This is what it looked like over the winter-

http://i252.photobucket.com/albums/hh15/siford/DSC02970.jpg

I am doing everything I can afford and have time for to make this a competitive XP car. It started as a '96L 2dr Impreza. I swapped in a WRX engine, did the wiring myself (with help from Nasioc and my co-driver), deleted AC, airbags, radio, and every other extra (not necessary) electrical component possible. Switched to a braille race only battery that weighs 5.4 pounds mounted in the rear passenger seat area. The interior is gutted, no sound deadening, no carpet, no passenger seat or belts. Hacked the dash to lose weight where I could and keep a decent mounting points for the gauge cluster. The front a rear bumper beams were cut up to just support the bumper cover, but don't lean on the bumpers. Fog lights are gone, all AC components are gone, all airbag components are gone, this car didn't come with power windows or ABS, so that saves me a little weight. Last I think is the home-made CF hood, reference this thread (http://forums.nasioc.com/forums/showthread.php?t=1487666). Final weight on the scales was 2367 lbs with 1/4 tank of gas.

Power comes from the '02 WRX engine through an 11 lb flywheel and excedy stg 1 clutch to the stock '96 tranny (I like the 3.9:1 ratio). I added a LSD rear diff last year to help direct power to the 225/50R16 V710's at each corner. The engine is helped by no cats, a 3" turbo back with a stromung dual dip muffler, TGV deletes, 665 cc injectors, Grimmspeed Phenolic spacers, an APS 65mm intake, and an enginuity tune to make it all work together. 236whp 240wtq is what it put down on a dynodynamics when it was tuned.

Suspension is Koni SA's in stock housings with a GC coil-over kit and 600F 650R springs. Helper springs are 200F 150R with 1.75" of travel in the helper spring at each end. 22mm whiteline bar up front, 24mm Helix in the rear through Helix endlinks. Noltec camber/ caster plates up front with Cusco GC specific camber plates in the rear. Whiteline ALK in the front with custom UHMW front control arm bushings. Chassis stiffening provided by GTspec fender braces (fitment on these is crap, but the work great once you get them in), a GC STI CF front strut bar, Whiteline rear subframe lock bolts, and a Rally Innovations Harness bar (these guys are awesome).

Interior additions include a Sparco 333mm steering wheel, a Corbeau Forza seat, Schroth 5pt. harness, assorted gauges on a center gauge cluster, and the ECU has been remounted on the center tunnel (just to be different).

My first event this year with the car in the described setup was in Iowa this past weekend. The car felt great and was much faster than I could handle. After some practice in it I think I should be able to post some decent times. Locally I have Steve G's (Mnbiker) XP Miata to chase, so the competition will be good (assuming I am anywhere close to him).

In the next few year I am planning on too many mods to list as the budget allows. First and foremost will be ~275 or 12" wide R-comps or slicks, a built tranny with good diffs, and more power.

I won't be at Nat's this year or next due to work, but 2010 I am planning on being there with this car to push for a decent placing. Should be a good challenge in the coming years.

Dude, that is so awesome! Best of luck

Oh, and you should definitely put an EJ257 in it, and get some 15x10" wheels with 275 hoosiers

Oh, and you should definitely put an EJ257 in it, and get some 15x10" wheels with 275 hoosiers

The 257 is on the list, but I'm still split between 15x10's and 275's or 15x14's and 23.5 x 13.0R-15 R25 compound slicks.

Thanks for the compliments.

Note that wheel widths beyond a certain point carry weight penalties in the Prepared category. At least, they used to.....

That said....I'd put some 13's on it just to be that much different!

I agree that an EJ257 would be a nice addition once you get a handle on what the EJ20 can do.

+12345 Sweet project! I'm jealous. :devil:

Sean, that's awesome!! First thing I thought when I saw that hood, is "man, he's getting really good". Glad to see you are finally able to make this your full blown toy car now!!! Can't wait to see some video from it once you've adjusted to it :D


oh, guess what I did this past weekend that reminded me of your garage?...more frozen lateral links :lol:

Congrats!
That is quite an accomplishment.

That is one cool car!

Got a good picture taken of my co-driver last weekend.

Geez that's low. Did you find it beneficial to lower it that far? I know I should lower mine another 1/2" or so, but it looks like your car is at least 1.5" lower than mine.

What are your ride heights (if you don't mind sharing).

Well, I'm guessing running 13" wheels has a little something to do with the overall height as well.

looks like its going well so far. I think u will progress quickly enough to show the limitations of the ej205. if u have the extra weight, always keep an eye out fo that ej257 shortblock.

i think u may be to heavy to see the best results of teh r25. r35 maybe more suitable?

bigger bar up front, and eventually ur gonna cage it and ditch the stop gap sreet bracing. then u'll have fun!

Yeah, the 13" wheels really drop the car down. To the point where it just doesn't roll much at all. That above pic is with 600F 450R rear springs and no bars at either end. My ride heights are 12.5" up front and 13" in the back. Here's another pic in a fairly heavy state of cornering.

I'm anticipating a little raise once we put the 15x10's on.....

Jay Storm

Sean, you need some new seat brakets :O

Got to take this thing out for a run during buck runs... i'm all strapped in, rev rev rev... launch... and the seat slides all the way back!

the best part, is the car's owner is running start marshal for me while i took the run!

Called the seat company the nest day and they are sending me a new set. I was less than pleased with Courbeau. Apparently they had a few QC issues with the early sets of sliders this year and I got one of those sets. For now the seat is riding on some modified stock seat brackets and it works great. It might just stay on the stock brackets for how much better they work (and they aren't any heavier).

yeah, I use to work at a shop that was a corbeau dealer...those seats are crap IMO...

"cheap" but you get what you pay for...

that is a pretty awesome setup!

Some video that was taken at an autoX/ high speed run. Very fun event, a short autox course followed by a ~0.2 mile straight before the finish flags. I took 3rd at the event behind a pair of Evo's.

2008-'09 winter update-

I took 1st in XP for one of the two local clubs mostly due to showing up to every event and a certain Miata not being so reliable, and not very drivable in the rain. I'm happy with that, but for next year I want to be competitive when that Miata does run. My local XP competition took 6th at Nats this year 2.244 seconds out of first.

Plans include-

275/35R15 A6's on 15x10's
lexan
Front splitter
PnP turbo
Turbo inlet
equal length headers
E85 tune
3" lightweight turboback- just far enough back to be legal
Cross drilled rotors front and rear - weight savings
built tranny
Clutch front and rear diffs
35/65 center diff
and I'm aiming for it to weigh in around 2100 lbs ready to run

This car won't be going to any road circuts, it won't be driven on the road, it will just be an autox car. :)

I got started last weekend-

http://i252.photobucket.com/albums/hh15/siford/DSC03935.jpg

http://i252.photobucket.com/albums/hh15/siford/DSC03939.jpg

Next I have to get out those pesky door beams. :)

Compare the wiring to the pictures above from last year.

http://i252.photobucket.com/albums/hh15/siford/DSC03890.jpg

sounds like quite the recipe sean...I'll be following the thread for sure.


Curious, how much does the car weigh now?

It was 2367 with 1/4 tank of gas at the beginning of 2008, right now it's probably 60 or 70 lbs lighter than that and dropping weight every time I work on it.

Sick!!!

Nice.......this gives me inspiration to take mine off the street for good.

Jay Storm

Made some progress today. :D

Finished cutting out the door beams-

http://i252.photobucket.com/albums/hh15/siford/DSC03989.jpg

Moved some wiring to shorten all the wiring lengths improve weight distribution-

http://i252.photobucket.com/albums/hh15/siford/DSC03986.jpg

Once I figure out the permanent mounting for all the wiring I'll start shortening up all the wires to their minimum length. I'm pretty sure that even with all the extra wires gone there is still 10 lbs of extra length of wire in the car.

It was really nice of Subaru to include the mounting points for the relays and fuse box on the passenger side of the car. :banana:

http://i252.photobucket.com/albums/hh15/siford/DSC03987.jpg

Got some work done this weekend, and I've been getting a lot of parts in lately.

http://i252.photobucket.com/albums/hh15/siford/DSC04029.jpg
I am really looking forward to the feeling of less rotating mass and this clutch off the line. Launches last year were good (thank you COM events :banana:), this year they should be even better if I can get the hang of it.

http://i252.photobucket.com/albums/hh15/siford/DSC04028.jpg

http://i252.photobucket.com/albums/hh15/siford/DSC04026.jpg
The wiring has been reduced to the bare minimum and cleaned up significantly. I decided not to tape it up just yet (at the advice of my co-driver) until I make sure that everything runs correctly.

http://i252.photobucket.com/albums/hh15/siford/DSC04027.jpg
Mmmm... extra light trunklid... Hinges weigh too much.

http://i252.photobucket.com/albums/hh15/siford/DSC04025.jpg

http://i252.photobucket.com/albums/hh15/siford/DSC04030.jpg

Keep up the good work. Progress is good, no matter how small it may seem right now.

Jay Storm

Man. I need to get working on the miata. NOW! lol makes any little thing I do seem like laziness.

Nice project. Would look better with a UND sticker on it though!

so messy with all the wires

It's gotta get ugly before it gets pretty.....


Jay

I'm jealous there's so little wiring in it.

Looks good!

Thanks.

The nice thing is that once you get it close to the minimum amount of wire, the ones that are left are pretty easy to figure out. :)

Got a little bit of work done over the last few weeks. Lots of weight is going away all over the place.


http://i252.photobucket.com/albums/hh15/siford/DSC04081.jpg

Cut down the rear brake mounts. The "new" piece weighs less than the material that was removed from the original.


http://i252.photobucket.com/albums/hh15/siford/DSC04084.jpg

Seriously cross drilled rotors for lower un-sprung, rotating weight.


http://i252.photobucket.com/albums/hh15/siford/DSC04088.jpg

The debris left over after you do this->

http://i252.photobucket.com/albums/hh15/siford/DSC04086.jpg

I have almost all the undercoating off underneath the driver's area and the drivers side wheel wells. A scraper was used for the larger flat areas and the crud thug finished it all down to either primer or bare metal.


http://i252.photobucket.com/albums/hh15/siford/DSC04093.jpg

The plug for the new and improved front bumper is almost finished with shaping and fits amazingly well. Glass will be ordered soon along with the materials for the splitter and the bumper.


A few other things are coming along nicely. I welded in the EGT bung in my new headers and wrapped them and the uppipe. I picked up the reworked turbo, the polycarbonate, the flywheel, and the crank pulley last week. I'm getting anxious for VF on May 2nd. :banana:

Front end looks good. :)

How big where the pieces you started with and what is the material?

I assume foam of some sorts.

Looks like 2" thick insulation foam. Found at your local Home Depot :D

Right on the money.

Started with 4' x8' sheets, cut out the basic shapes, glued them together and worked from there.

Excellent work!!!!

All ideas noted for future use.....

Jay

Nice job on the front end.

Nice I hadn't seen this before - I'm building my '93 wagon for XP as well, lots of good ideas.

I dunno if I'll go as far chopping down wiring but is certainly interesting. I think my wagon is in the 2,400lb range, I need to weight it again after I did some more weight reduction. I wanna do Lexan windows too, I think the wagon can drop some decent weight with it. Need to pick up a Braille battery too. Have you considered doing a fuel cell? I've been kicking around the idea, not sure what weight savings there is there but maybe can play with weight distribution?

I need to really decide if I'm going completely dedicated autox car and get rid of my front big brake kit... so I can run a much lighter/smaller tire setup.

I was pondering gutting all my e-brake hardware and possibly trying to track down some aluminum hat rotors for that rear that don't use the center drum style e-brake to drop some more weight.

Mine rides really high, especially compared to Jays:

On GPMoto coilovers right now but pondering something different

Definitely cool to see someone else going to a little different class. I have my work cut out for me at my local events - there's a guy with a LS3 powered 240z widebody on 13" slicks (formula atlantic ones iirc) but he's more of a hill climb guy I think... still tough competition. Not to mention the Volkswagens here that thrive on the short courses.

I'll have to take some pictures of my gutted interior and that sort of work - guess I don't have any hosted right now.

Pure titstacular
im loving it
and i know you can get it at 2000 even ...
Ever think of cuttin the stuff in the trunk or getting a CF trunk or the trunk you have now is light
enough?

Loved what you did with ecu mounting/gauges also

+5000 to you

I built a 98 Impreza for SM that is about $500 from being finished that I haven't worked on for some time (like 2 years...) Of course now it's way underweight for SM so I was thinking of just playing in XP.

When I built it the minimum weight for SM was like 2600 lbs. I was able to get it down to around 2400 lbs with JDM bumper beams, and that's prepped for SM and not XP, so I think getting it own to 2200 lbs is doable with all you can do in XP. The car still has all the dash elements, the headliner, etc. etc.

I rebuilt the entire wiring harness from scratch to save weight, and also remounted the ECU. It's hard to get around the "mess of wires" however when things are all bundled together.

I've been contemplating selling the car since I haven't worked on it, if someone wants to save some time and money. :)

Phil

Phil....you're a bastid.....tempting me like that!!!! An STi drivetrain in a 2200lb REAL IMPREZA shell??? Are you kidding me? This is exactly what XP needs!

My wallet officially hates you...... ;)

This thread has somewhat re-invigorated me to just finish it. I went ahead and bought one of the parts I needed, an alternator. Now all I need is an air/air intercooler. The air/water route sounded cool initially but it's a bit of a hassle and I found the heat soak to be pretty bad if you weren't cycling new ice water into the reservoir. Here is what the car has currently, not sure what I'd want for it, I'll have to do the math.

1998 Impreza shell
JDM Aluminum front hood
Autopower roll bar
Battery relocated to trunk
ECU relocated to under passenger seat
Recaro Prodrive front seats, newer G-force harnesses


GC Advance Design Coilovers, MRT caster/camber plates up front, MRT camber plates in the rear
STI CF front strut bar
Ebay rear strut bar
Cusco Type-2 GC front underbrace
Rev-Lab 10.5:1 Steering rack
STI (pink) rear trailing arms w/Solid bushings
Poltec Aluminum lateral links
Poltec Aluminum swaybar links
Cusco 22mm (i think) rear bar
Whiteline 24-26MM front bar
Modified RS subframe to use a WRX swaybar
Willwood lightweight 4-pots front/rear
H6 rear rotor upgrade
16x10" Real racing rims (15" shells could be used instead)


2.5L STI block w/CP pistons
Ported V8 RA heads (Pure tuning) with DPR AVCS came (264)
External wastegate setup (Ultimate Racing Ext Gate uppipe)
Couple different turbos, PE1818 and a 20G
Magnaflow Ti catback
PE650 Injectors
Hydra ECU w/launch control (older revision)
JDM V8 RA ECU that was programmed by Cobb Tuning (could be used instead of the Hydra, but the car has no MAF currently)

6MT trans w/Cusco Type-1 RS front LSD
STI front axles
Cusco engine/trans mounts
STI rear differential mount (
R160 rear with Kaaz clutch type LSD
Lightened flywheel (12.9 lbs), I also have an STI lightened flywheel (~15 lbs) that could be resurfaced
Decent race clutch (I honestly can't remember who it's from, isn't that sad)

I thought the light weight bumper beams were illegal in SM:confused:

They are, I had both the lightweight and the regular ones. I weighed the car with and without them at different times.

Auto driveshaft out of a 97 OBS (that's my baller piece right there:lol: )
15 lbs flywheel
stock clutch

Still have the full interior (except the back seat/back seat hardware per SM rules) and I'm going to be pulling the air bags this winter to drop some extra weight up high. Never weighed it, but I did some basic calculations and it should be right around 2700 lbs. If SM allowed light weight beams and carbon trunks I think it might be down to 2620 or so, but that's just dreaming right now:p

Be careful of how light you go in SM, the minimum weight is fairly high for a 2L, turbo, AWD car. Think of it in terms of the more weight you can take off, the more you can add where you want it in parts that will help you.

On a more cheerful note- My car runs! :banana::taco::banana::taco:

Seems like it's been a long time since it made some noise. When it makes a noise it's really loud. :D

SM has a new weight limit this year for 2L forced induction AWD cars with tires of 275 and under: 2620. They upped the weight allowance for 275 or less tires to 200 lbs from the 100 lbs last year. So that's my new goal:D

Good deal on getting the car running! Mine's still in the garage waiting for me to put the intake manifold back on:(

Got an alignment and corner balance today at Jeff's. Front camber was a bit of a pain to get dialed in, but Jeff got it right where I wanted.

With heavy wheel spacers made from the centers of old brake rotors the car weighed in at 2095 lbs without the splitter. The splitter weighs in at 13 lbs with mounting hardware putting my running weight at 2108 without driver. With my fat butt in it I'll be at 2300lbs even on course. I have aluminum spacers on the way that should cut a little weight out of it. :)

Cross weights were set to 50.1% / 49.9% along with ride height and toe front and back.

Tonight I finally got the clutch pivot arm plug in (thanks Shane), and the rear half-shafts seated in the diff (for everyone who I discussed this with).

With a few final touch ups to the placement of the splitter...

http://i252.photobucket.com/albums/hh15/siford/DSC04153-1.jpg

And some final work on the splitter itself...

http://i252.photobucket.com/albums/hh15/siford/DSC04169-1.jpg

Along with engine tuning later today we will see our first event on May 2nd at MOWOG #1 in Minnesota. :banana: :D

Looks like great progress!!!! Can't wait to see how it runs now!

Jay

Awesome Sean!!
Can't wait to see how it turns out!!

Wow quite a car! That front splitter is interesting! Cant wait to see some pics of it in action. I wish you the best of luck. It will be inspiring to see an Impreza running competitively in XP.

can you post or pm me your specific corner weights? I'm currently running a 05 sti in SM. Just bought a 93 that is going to get swapped for SM. Curious about how the swapped gc is balance-wise.

thanks

brilliant build by the way

Those are as of last week with me in the car and enough fuel for a full days of autoX. I have done quite a bit to move weight back and to the passenger side. I'm not sure how much you can get away with in SM anymore (it's been a while since I played there).

Just for fun-

The new dyno graph. :) I think my engine and turbo may be getting tired.

yeah, definately chasing a dropping torque curve there. what turbo are you on now?
I know its still the stock EJ205 and are you still on the wrx drivetrain?

I can't wait to hear about how the new setup runs and even more so, see video of it :)

EJ205
CAI
Turbo inlet
PnP Td04
Sparco Intercooler hose
PnP TGV deletes
665 cc injectors
Perring headers
Crucial up pipe
Stromung down pipe
3" Titanium tube for the remainder of the exhaust.

Drivertrain is an '02 WRX tranny case, with a Cusco 1 way front, PPG gears w/ Andrewtech ratio's, Cusco 35/65 center, Cusco 1.5 way rear, and 4.44 FD. Should hold up pretty well and put the power down without a problem.

It sounds loud. Ridiculously loud. I will post video once I have one.

Wow! Only 2000#, but 67% front weight. Hopefully the interior moves the weight bias back a bit for me. How many g's did you design for under braking? I bet those front tires are pissed :lol:

and thanks for the info

It's 61.3% front bias. Not great, but not horrible either.

I didn't design anything in the braking system, it's all subaru parts. With less mass to stop, they are not as highly loaded as if it was stock.

I ran my first autoX with the new setup this past weekend. Here are my driving impressions.

First off- Clutch diffs require a break in period, I did not have time to completely break in my diffs, so they were very grabby at first, and got better with each run.

Second- I was using year old V710's due to the lousy tire shredding surface at this venue.

My first run was embarrassing. From the start line I bogged the engine a little, then 15 feet later hit full boost just as I was starting to turn into the first corner. I was the first car out, and the lot had quite a bit of loose rocks on it. I spun 180 degrees. When I stopped spinning I had made it 30 feet from the start line. The rest of the run consisted of me trying my best to modulate the throttle and keep the car pointed approximately the correct direction.

My second run was slightly better. I made it until the 7th corner when I spun the car, this time 360 degrees and I was going fast enough when I spun that I never stopped making forward progress. I didn't hit any cones either, and got quite a few cheers from the crowd.

My fifth and last run I finally managed a decent time and finished .2 seconds behind 3rd place in class (out of 5).

My co-driver won the class (beat me by 1.2 seconds on a 68 second course).

Day 2-

Still struggling with learning to drive the car on a much more technical course I again placed 4 out of 5, but this time with my co-driver placing 5th.

The car is amazing. More power than I can handle, but the diffs keep me from ever spinning 1 tire. It doesn't handle like an AWD car anymore when you get on the power. The rear toque bias is great for rotating the car whenever and wherever you need to. The power delivery is awesome as long as you are above 2500 rpm. Throttle modulation is required everywhere on course. If the steering wheel isn't close to straight ahead and you get on the gas the car will start to rotate. Part of this is the diff's not being fully broken in.

Assuming I learn to drive this car again it's going to be amazingly fast.

sounds great Sean!! too much power is always a good problem to have when you consider the stock EJ205 still being on a TD04.

What is the biggest issue with the power of the car? torque delivery? lag to sudden spool? peaky/sudden torque (turbo spooling too quickly perhaps?)?

Regardless, I can't wait to see some video, ESPECIALLY once you get the car (and driver ;)) dialed in :banana:

MoAr seat time....that's all. You'll get up to speed with the car and the diffs will mellow out. Keep up the good work!!!!

68sec course? :eek:I'm jealous!!!!

I'd say the car's too tight.:p;):)

I'd say I can sympathize on learning to drive a different car, and adjusting to on throttle oversteer. I had similar results this year the first time in my car with new diffy goodness.

No where in the description did you say you had one of these :D on your face. You must have and that's what it's all about.

I'm with Jay more seat time in it and I'm jealous of the ~70 second course. You'll get acclimated to the car.

G/L sounds fun.

wow thats really impressive. its amazing the work you do just to shave off the littlest of weight. btw, what is the weight of... lets say a stock 2000 rs coupe loaded with options? just to compare it to yours =)

From the references I could find a stock 2000 RS with the 5 speed manual weighed in at 2857 lbs. So take off 750 lbs and you have my car. :D

750 lbs is anything but "littlest". Do the math and come up with a percentage. It's work....but WELL WORTH the effort.

bumpity for video ;)

We had a '99 STX class 2.5RS down to 2710, with stock seats and battery. I think Corey Ridgick had his STS 2.5RS down to mid 2600 range.

Anyways, love the build. I think the process you are taking is much smarter than most of the monster HP SM/XP builds I've seen. I can never understand why Subie people think going for the 400-500hp mods first will make a great autox car. It is as if they've seen the ST Civics or CSP Miatas run before.

I'll try to get some video this weekend and post it. I didn't get any during the test and tune and even if I did have some from my first event, I'd be too embarrassed to share it.

This is great info and thanks for all the updates! The transformation has been interesting to see.

Very nice keep us updated on the progress... If only I had money to fix up my h-stock honda civic

Finally- after much messing with trying to get video processed.

It's not a good run, on my best run of the day the camera battery died.

A quick vid of the start by someone else.

Looks pretty good! Nice progress on the car.......witholding comments on the driver.... :D

In the vids, were you still on the year-old v710s? Car looks like it has some real potential, now drive the lines and use the engine.....

You should throw on some fender flairs or go $widebody$ in the future just a suggestion unless thats not allowed in xp.

:huh:

Why? It costs money, adds weight, takes time, and doesn't help performance.

^^^ I agree. Leave the exterior alone......Once you get used to it, it's gonna be a rocketship!!!! I'm jealous!

Interesting autocross site in the videos, where is it? What sort of use does the site normally have?

Looks like a Kart track to me. BeaveRun in PA is very similar. If it IS BeaveRun....I'm gonna be upset, as it's a litle over 1hr from me. :(

I was on the new 275 Hoosie A6's. "Drive the line" is what I repeat to myself every time I'm at the start line. After thinking about it for a while I should have been shifting back to 2nd in a few corners.

Interesting autocross site in the videos, where is it? What sort of use does the site normally have?

It is a drivers training area. Normal use is training Semi-Truck drivers and police how to drive. Pretty nice place overall, but the course designs are fairly limited due to the road course type of layout.

Not BeaveRun, I live in Minnesota southeast of St. Paul. Thus the "They eat fish soaked in lye" comment. Lutefisk is Cod, soaked in lye, then soaked in fresh water, then cooked and it's ready to eat. Minnesotans eat a lot of it, and yes- it's as gross as it sounds.

St Cloud HP test center? If so, "DON'T CUT" should be a mantra as you drive. Fall off the inside shoulder and you are into 1-2 foot deep ruts. :eek: :sadbanana:

Dakota County Technical College. No one runs at St. Cloud anymore as there were a few incidents there with a few different clubs.

who was the driver in pro that drove your car today?

MAN that car was moving!

Neal Tovsen. I was glad to finally give the car a driver that was worthy of it. He finished 19th in PAX, which is pretty good considering the competition that was present. With Neal coming in behind Mr. Aro in the CSP miata on RAW time tells me the car still needs a little work, but the driver (me) needs a lot more work than the car.

It was a great event in Milwaukee. Had a few problems towards the end of the day with what appears to be a sticking relay, or a dying fuel pump, or possibly a crankshaft position sensor that is going bad, or maybe something else. Troubleshooting this week with a small local event next weekend to finish figuring it out.

Even though I'm not a good driver, this car is a blast to drive.

That is what it's all about man....keep up the good work!

some pictures of you

Glad you are having fun with it Sean. Such an awesome build.
So when are you going to do some weight reduction from inside the engine :p

glad to see this car signed up for the Midiv this weekend. Looking forward to seeing it in person and in action.

Mid-Div's were awesome. I ended up taking the last trophy spot in XP (3rd out of 8) behind a S2000 and a RX7. I needed to go much faster on Saturday, and only a few tenths faster on Sunday to catch them. I'm pretty sure the car could have done it, but my driving needs work. To make up for my lousy driving I have a few ideas in mind for this winter.

Meeting a few of you in person was nice after getting advice and help with my build problems. Hope to see you guys again soon.

I won't be at Nat's this year, but next year am planning on making it to Cen-Div's in Milwaukee and Mid-Div's in Lincoln as well as Nat's. Hopefully with more skill behind the wheel. :)

If you find any pictures of the event please post a link.

Was nice to meet & chat w/ you for a bit this weekend. Good luck w/ the car.
