The Mitty and Deal's Gap were a success! Had a ton of fun. Yesterday I was at the drag strip and tomorrow I'm going to Putnam Park road course to spend the next two days with 10/10ths doing track days.

Here is a teaser of the car all ready to go...

A couple vids from this past weekend! First one I just a short session I did at the end of the second day. Remember this is my first Track weekend so I think I did ok since I got moved up to the Intermediate group the second day. Track temps kept me from really running the car hard back to back, so you will see a few cool downs in here:


Next one is my one mess up of the day, trail brake too much going into turn one and almost spin it! luckly I bought it back together and stayed on track though!

Default Long due update!

Wow, can't believe I haven't updated this in a while.

So here is a rundown of the last few months:


Went with my GF to Mid-Ohio for the Rolex/Grand-Am race and took a few shots of the Subaru Road Racing Team's STI:







Had a busted inner CV boot on the passenger side and decided to buy a remanufactured axle from NAPA. BAD CHOICE! after one fell apart just trying to put it on and the second one fell apart within about 15 miles of driving I went with a reman from subaru and havent had an issue with it. here is the NAPA(LEFT) Subaru remanufactured(CENTER) and OEM(RIGHT) looks can be deceiving!



Next session at Putnam was July 1st. It was a hot one with highs around 98F! Apparently my car had a vacuum leak the last time I was at the track which was causing it to over boost and then cut boost down badly. I fixed that this time around and the car was MUCH faster. I now needed to brake for a turn i normally didn't have to and I eventually ended up going in too hot and braking over a small crest. The RCE springs are just too soft for track use and the car has a lot of dive while braking followed by a long recovery time. the following video is the result of all of these factors combined:



Needless to say I decided i needed more spring rate so I picked up the ground control kit with 500lb front, 450lb rear springs. This would be around a 70% jump in spring rate from the RCE yellows but keeps the same overall balance. Installed the kit but soon realized some modifications needed to be made:



The original spring perch is in the way of the GC perch so you can adjust them the full range. Took it all apart and took them to work to fix the issue:


few minutes on the lathe and the old perches were gone!

here is a comparison and the final result after i added some helper springs:

Default Part 2

Second issue was that i wanted adjustable rear camber so i bought some Vorshlag camber plates for the rear since they come with the spring perch for my new springs to fit. Problem was i ended up ordering them for 8611's instead of 8610's so the spacers were 1mm too small (I emailed Vorshlag but never got a response on sending me the correct hardware) so off to work again and made short work of that problem with a reamer. But then i realized that the bearing was so big the original nuts could only start maybe 1 or 2 threads before being tight so something else had to be done.

I took the idea used for the MSI front plates i have which use tube nuts. After a little measuring and comparison, ordered some 316 stainless bar stock and made a couple at work from scratch:


Here they are installed with just enough room to still get to the adjustment on the koni.


So coilovers were finally on and i set them to the usually recommended ride height of 14" front 13.375" rear. Here is what it looks like now:




After that went to Mid-Ohio with my boss (btw I love my job) to run with the Allegheny region Porsche club of America. This was my first time at Mid-Ohio and I LOVED it! The track is so much fun and so complex it is like a roller coaster. My instructor drove an EVO IX and was surprised at how well my car turned in compared to his. I went for a ride with him and his car understeered pretty badly on turn 11. I dont know his exact setup but I cant say I want to switch to an EVO after riding in it! lol

Anyway I only got two sessions without him in the car. He weight 220 and wanted me to use the "School Line" (Read safe/slower line) So I didn't get any practice on the line i would prefer and still need to work on several areas where i didn't carry enough speed. Either way I was doing good enough the first day that my Instructor bumped me to C group (which they usually require at least 10 track days before going to that group, I had 3) and I was out pacing some of those guys in faster cars than mine.


The Car in the video in front of me was a CTSV Wagon. 556hp helped him a lot on the straights but i made up a lot of ground in the turns. Behind me was a guy in a '12 Cayman R. He approached me after the session asking what all was done to my car because he said he couldn't catch me at all. I blew his mind telling him I had probably 50hp less than him and weighed 400lbs more!



Here was the joint run group with D and C together. You will see a friend I made there in a BRZ at one point in the Vid. Props to him for taking it to the track right after break in!


Had to cut this session short because I was almost out of gas! Filled up before I got to the track that day and averaged 9.5MPG!


Now up to date! I just got a set of Fifteen52 Tarmacs in 17X9 to daily on so I can put NT01's on the Team Dynamics. Here are some shots of the test fitment:





well that is all i have now! going to Putnam again in 2 weeks for the last track day of the year. will post updates again after I get the Tarmacs on and that track day over!

Default Data acquisition goods.

So I'm a engineering nerd and want to set my car up to the best of my abilities, so I'm slowly picking up all the tools I will ever need to diagnose, tune, adjust and setup my car.

First off after doing some re-search I realized that sting alignments are pretty much the most accurate you can get at aligning a car. More so even than some quality alignment racks. The local shop I always take my car to has a pretty old setup, which may be way out of calibration. Two alignments ago I only got about 2.5 degrees negative camber from my front driver side. So I slotted the lower strut bolt more to get more. Went back and still was only able to get about 2.5 degrees max which had me scratching my head a bit. Just by looking at it it seems to have more than that.

Downloaded an app for the Iphone called Clinometer which measures degrees using the phone's gyro's and appears to be pretty accurate. I got a flat piece of aluminum square tubing cut to length so that it will touch the outer edges of the wheel. Holding that up flat against the wheel and putting the phone up against it shows 3.4 degrees negative camber.



Passenger side is exactly the same and it is suppose to be 2.8.

So needless to say I'm doing my own alignments from now on and now have tools that show repeatable results.

Since doing my own alignments, I need to know exactly how much camber I can run. This also allows me to get a little more extreme with the camber since I can simply re-align the car once I get back from the track. The best way to tell if you are running enough camber is by reading tire temps, so I picked up a Longacre pyrometer.



Probe pyrometers are the most accurate since you can get down into the tire and read the core temps. The temps read from an infared pyrometer are only on the surface which rapidly cools down once you leave the track.

I will be taking data on tire pressures and temps on my Star specs and reporting back on here anything I learn.

I'm probably going to string align the car this weekend so I will post then how it went.

Got my Carbotech XP12's in and put them on with some new centric rotors in the front. Still running Ferodo DS2500's in the rear and I think it will be way too front biased but its only for one track day with light braking anyway.


One problem with the Carbotech's was the pad material was slightly misaligned on one of the back plates and wouldn't go on, I had to grind down a small bit of material for it to fit. You can see how the back one is off in this pic:


As for rotors i use plain old centric blanks and they seem to hold up pretty well:


I used the ABS cycle procedure and a Motive power bleeder along with ATE Type 200 to bleed out my old Super Blue.

I know have a very firm pedal!

Default Alignment

took the time yesterday to do my own alignment. probably not the most accurate but i got it as close as i could. took about 5 hours.

First I canted my camber plates more so I could gain some camber. Ended up being just enough. Originally had them set for maximum caster only and slotted the lower strut mounting bolts to try and get some camber. Only had about 3.4 degrees but wanted a little more. So I moved the studs over one position in the MSI camber plates and ended up right at 4 degrees camber on the front drivers and 3.8 on the passenger side:


strung it up and dialed in the toe which was pretty close, just moving the plates added a little toe out. after a lot of checking and re checking i got it as close to zero as possible.


Final numbers are:
Camber:
DF: 4.0
PF:3.8
DR:2.6
PR:2.6

Toe: 0 on all corners

Car is all ready for Putnam this coming weekend. The Carbotech XP12's are a pretty good street pad IMO. Have much better initial bite than the CL RC6's I had previously. Will update after I get back from the track with some vids.

Few Pics of the Tarmacs finally mounted on my car! Went with 245/40/17 Hankook RS-3's since my Star Specs are about out of life and I just signed up to do a track day at Road Atlanta next month! Cant wait!

Quick update after the track. Dropped over a second off my time from the last time I was there. The star specs did great! My alignment was also pretty good for my setup with temps having a 10 degree spread across the tires. For reference to anyone else I ran (cold pressure) lf36, rf35, lr35 and rr34.5. This was Putnam park which has a lot of right hand turns and concrete. I still have at least another half second in driver error and I never changed rear swaybars setting which might have helped balance the car a bit more. Also my brakes started to get spongy the second day. I probably need better rear brakes to help out the front and also some brake ducting wouldn't hurt.

I'll post some footage tonight. Next month I'm going to road Atlanta to finish off the year. For now here is a pic of the new wheels in the daylight. The RS-3's did good but still need to be broken in a bit before I can really tell if they are faster. Definitely softer sidewalls but not really bad.

Just got my used oil analisis back from Blackstone labs. Things are looking great!

Sent this out after my Mid-Ohio weekend and I'm amazed by the results. I hoped it would be good but this is a huge piece of mind! Rotella T6 is the Chuck Norris of oils!

Default Putnam Footage.

Here are a couple of videos from last weekend. First is my data overlay of the fastest lap i did: A 1:23.4

Not too bad but there is still a little more in the car, I think I can improve in a couple of corners so maybe i could get that down to a :23.0 then all I need is some NT-01's and I will be knocking on the door of the TTD record. Cant wait till next season to take a crack at it!


Next is just a few laps and me running up on a couple Lamborgini's. The Diablo in the vid is non other than the one this guy brought as a backup since he crashed his Carrera GT and caught it on fire that morning: Carrera GT Crash



Road Atlanta in 1 month!

Default Update

Haven't updated this in a LONG time, but im getting the car ready for the next track season and figured id post my progress this season:

This weekend I finally got around to getting all my brake ducting installed.
My setup includes Chargespeed brake ducts, Rooduct intermediate ducting, Quantum Motorsports duct plates and some 3" high temp silicone brake hose.

I trimmed the OEM dust shield so the plates would fit around them. its a good idea to keep the dust shield to protect the ball joint and tie rod boots from the heat.

Drilled and tapped holes 8-32 holes for the Rooducts. These are made to keep 100% of your stock wheel clearance while still routing air to the brakes with minor modifications to the car.

Routed the hose to connect everything and made sure there was plenty to extend through the wheel travel.

I ziptied the Chargespeed ducts into the fog lights holes and it actually holds them very securely. The pics below are the end result:











Last pic shamelessly stolen from Chuckles (Charlie Smith)


Still need to replace my front driver and rear passenger wheel bearings and then ill be ready for my first track day which is at Putnam with 10/10ths on May 5th. Then 2 weeks after that at Putnam again I will be at the NASA event. Probably wont update this until after those events.

Nice build.

Couple questions though, how do the oem brakes hold up on the track? What kind of fade, if any, do you experience with the carbotech? How do the rotors hold up pair with an aggressive pad?

Thanks!

Well the OEM brakes do pretty well. Biggest problem is heat, which I'm hoping the brake ducting improves on quite a bit. I have zero fade issues with the carbotech's or the CL RC6's. Only issue i had was the fluid braking down quickly and the peddle getting spongy by the end of the second day. After i switched to the RT700 brake fluid no spongy peddle.

Rotor wear isn't bad imo. I tracked and DD on the same rotors all year last year. (9 track days) They are actually still on my car until i put a fresh set on before the first track day.
