Everyone seems to love those tires

If I didnt want to stress the oiling system more I would go to an R Comp but 200tw street tires will do for now.

Do you guys have full length onboard videos of the car I would love to watch them

Hi Gigs,
I don't have any recent full length videos. Since I mostly do 1 hour enduros they are pretty boring to watch the entire thing, and uploading one hour videos recorded in HD takes forever. So I try to pick a few laps with interesting parts and put them up. For the upcoming Spokane races I'll try to make a medley of videos.

So far the heat is not an issue after two hours of track testing at ORP. One place the exhaust tip touched the cut out portion of the Alumalite is slightly melted, we'll cut it back another 1/2".

Rear Diffuser finished. Aero wool tufts and camera setup for test. Next stop Pacific Raceways (Auburn WA) on Friday for Test & Tune. If all goes well then the 1 hour Enduro race on Saturday afternoon.


Did you notice any temperature increases in fluid temps after doing the full flatbottom?
I did my first event with my new splitter/air dam that only extends about 3 feet total, and only covers about 1/3 of the engine bay bottom, BUT cut off all the air that used to flow under the car and up into the radiator/oil/power steering coolers. My oil, power steering and coolant temps all ran a good bit hotter than before the new front aero setup:

Oil temps are up. I'm going to make some mods to address it. It probably has more to do with the dry sump than the flatbottom. Coolant is fine except a leak at the turbo. Trans is fine, it hit a max of 220 during the Spokane Enduro. I'm finalizing a gauge on the Diff now, I should have temps on it next race.

The Blue Sake Bomber took First Place in Class and First Place Overall at the Northwest Motorsports Spokane Grand Prix Enduro. Special thanks to Subaru of Bend, your support over the years has been great! And thanks to Surgeline, and Arcflash for your help.

Yea, that's a fantastic result. You should start looking to live stream in-car of your events. If you need any assistance in doing so, PM me. I live stream all my AER races here in the East with great success.

Most tracks out here have awful or non existent WiFi. I'd like to hear more about how you do it!

Not wi-fi, LTE cellular. If you have decent coverage at the tracks, you can stream easily enough. I'll PM you.

On a related front, we've been chasing oil leaks in our 818R but finally got them dried up so we headed to ORP for some test & tune time!

The test & tune at ORP started off really well. The oil leaks were all gone! Once that was confirmed we started pushing it a little harder and harder.

Later in the afternoon when the track was at least 100 degrees or more, and with the help of another 818 builder, we did hot pit tire temps with a needle pyrometer. I was very pleased with the temps on my new Hoosier R7's. Very consistent 160-165 degrees across the treads. I was expecting them to be quite a bit hotter, Hoosier recommends 180-220 degrees for optimum stick. That's telling me that going to a wider tire is not going to help, at least not until I really start hammering on it hard.
Front: 225/40/17
Rear: 245/35ZR18

Then it happened. The 2004 WRX with Cusco 1.5 LSD trans broke. Loud clunking and an awful thump emanate from inside it now. We haven't taken it apart yet to see the exact damage, that will be later this week.

Then insult to injury: On the tow in the tow line came undone, the rope went under the right front wheel and wrapped around it, smashing/cracking the fiberglass fender out from the inside, and tearing off the brake line!

So back to the shop for fender repair, brake line repair, a rebuilt 5 speed, and this time a trans cooler package. I knew I should have done the cooler, and I can't say it would have helped for sure, but I will do it now that it's getting re-done anyway.

A few pics here, a one lap video later this week:

Sorry to hear about the setbacks.

If I remember right, the 05+ Legacy 5MT is considerably stronger than the earlier WRX transmissions. You should double check that theory before acting on it, but... if I'm right... the stock LGT 5MT transmission might be a better choice than upgrading the existing WRX transmission.

NSFW, thanks. Yes the LGT 5MT is stronger than the early WRX. It also doesn't have a speedometer connection inside, which leaves the speedo port available to run the return from a trans cooler. I had a cooler setup like that on my SRRT LGT wagon car that Phoenix Performance ran in the Grand Am Cup. But then the oem dash speedo won't function. That's fine if you are running an AIM or other aftermarket GPS based dash.

To keep the factory speedometer I should upgrade the internals with newer model gears/syncros/forks...

if you want to keep the speedo, you can get a wheel speed sensor adapter.

Thanks, checking into them now. Do you know if there's an adapter to fit it? Would mean custom CV axles, a new shifter and cables, clutch....

Precision Chassis (you can find their Boxster build on here) had done them but I don't know if they make them anymore.

After the high point of the season, winning the Spokane Enduro, things went downhill badly for the Blue Sake Bomber. The Turbo fried and came apart, the head gasket leaked, and general bad news. All of it traced back to the helicoil repair on the block. So out with the old and in with the new. And what's the point of a rebuild if you don't do some upgrades!

Outfront Motorsports V3 Closed Deck 2.5L Shortblock
BC Stage II Cams
ATP Gen II 3576 EWG Turbo
Dom's Cyl #4 Coolant Mod
Outfront Valve Cover and Block AN fittings for the breather hoses.
Radium Engineering Surge Tank mounted in trunk.
Electrical wiring cleaned up and better connectors.
Reroute breather hoses.
Heat shield for the Vehicle Speed Sensor in the Tranny. I've melted two of them now!
Re DEI wrap the headers.
Ongoing mods to improve the flatbottom undertray and dry sump tank breather system.
Additional gauges to monitor Diff Temp and Crankcase pressures.

We've fired her up and run in the cams for 20 minutes, then let her cool off before putting her on the ArcFlash dyno for another couple of hours of break in and engine tuning at wastegate spring pressure, around 12 psi, with a RPM limit of 5650. At that pressure and RPM it made 338 HP / 327 TQ. I'm looking forward to the full potential of this turbo and cams.
Coolant and oil temps were excellent.

The Plan: Go up to Oregon Raceway Park for a full track day of break in at wastegate on Friday. If that goes well then get up early Saturday and head to Portland International Raceway for the ICSCC race where I'll enter the Enduro in ME0, still running wastegate pressures. Then back to ORP Saturday night for a day of track time on Sunday with the BSB and some time in the Acura Integra, Rocky, that I still half own.

And a side note: The new tranny for the 818R has arrived from ZF Design. All new syncros and LGT gearing. AN fitting in the top rear for a transmission cooler return. That should be back on track next week. We have another Time Attack race at ORP set for Oct 5th, I hope to have the 818R in that one.

I'll post up some pics and hopefully a track video from the Enduro early next week.

Sorry to hear about the setbacks. Keeping a Subaru alive on a road course sure can be a challenge.

I'm super curious about your new turbo though... it'd be a straightforward swap from my current ATP GT(pre-X)3076, so I've been wondering where the powerband starts on that one.

I'll post up a dyno graph when we get the final tune done. For now I'm pleased with how it's starting off. However that will be awhile before we have that tune.

And yes, it was a straight swap across for my ATP 3067 EWG.

We had some shake down problems at ORP. We weren't able to control the boost to 13-14 psi and over-boosted a few times. Luckily the fuel had Boostane in it and the tune was setup to keep the AFR fueling going beyond the normal boost levels so no damage.

The excellent news was the coolant and oil temps stayed just right! the new Dom's cyl #4 seems to work, although water temp hasn't been much of an issue so hard to say for sure.

We are experimenting with a different system for the crankcase/block/dry sump vent system. It seems to work great with two major benefits:
1) The block NEVER goes into positive crankcase pressure. It typically stays around 12-14" of vacuum. And even while on full boost, even over-boost, the crankcase& heads stayed at 4" of vacuum.

2) The heat in the oil is reduced so that I never saw more than 220 degrees of oil temp.

Excellent!

We are setting up the 818 dry sump with the same system. If both cars have good results I'll post the details on what we're doing, but not until I'm sure it really works.

The excitement of the weekend was that two different cars caught fire while on the track. The first was pretty badly damaged, but since everyone had practice on the first one the second was saved much more quickly. And people ask me why I ALWAYS put on my fire resistant driving suit before I go out to run just a few laps to test some minor tweak.... No drivers were injured in these incidents.

Then it was off to PIR for the Enduro. That was not good. About 45 mins before I had to go to the grid I filled the main tank and Aux tank to the brim. I walked away, then came back 10 minutes before time to head to the grid and figured a few air bubbles may have come out and I could get another 1/2" of fuel in the aux tank. I popped the lid off and what do I see, almost no gas in the tank? What? There should be 3.5 gallons in there!

I looked under the car and sure enough there was gas dribbling at a very good rate on to the ground. I was parked in the dirt, so instead of it running out from under the car it just absorbed into the ground. And it was dribbling slow enough that it made a very small puddle. There wasn't time to trace down and fix the leak so that ended my race weekend.

The Blue Sake Bomber is back in the shop to figure out what was leaking.

There's always something, but at least I didn't go up in a giant fireball!

Amazingly I am still in first place in the Mini Enduro championship points race.

With a couple more Test & Tune days under our belt at Oregon Raceway Park the Blue Sake Bomber is in good shape.

This Saturday, Oct 19th, is the Cascade Enduro at Portland International Raceway. It's also the season finale that will determine the Enduro Championship. I am currently in 3rd place but because the Cascade is worth double points I have a fair shot at the Championship.

The BSB is primed and ready to battle for the Championship. The race starts at noon with one of the last LeMans style starts in the US. (Drivers run across track, strap in , and take off, all hopefully without running anyone over or hitting another car!).
