I read the post by Tim about The Glen on May 10th and 11th
http://www.dsmtuners.com/forums/showthread.php?t=227197

I was there with my '99 GS-T. My brother took some video, which I edited and threw some music to. I'll put the link at the end of this. I don't have an in-car camera mount yet. I was just signed off solo at this event (2nd time at Glen), so I really didn't need a camera yet.
The only issue I had, was that my Wilwood brake rotors expanded enough from heat to start milling out the caliper on the drivers side ! This was an error on my part, since you have to decide how far to shim the caliper from the rotor. I got greedy for pad surface I guess. A quick shimming after the first run fixed the problem. I thwarted knock by running 100 octane, and on the second day I turned on the water injection (3gph). I wish I ran that the first day ! It didn't use that much of the tank at all, and the car ran like a monster. EGT's were lower, and water temps crept much slowly up. I need to add a larger radiator, or rid the FMIC like Tim did. I was thinking of putting a 11x7x1" radiator where the SMIC would go, and use the 3/8" connections that would normally go to the oil/liquid cooler. They are currently blocked off. Thoughts on the heat ejection I would get from that would be appreciated. I ran 15-17psi boost for safety, and the car survived the two days and 400mile round trip drive. A dyno tune before going to the glen, let me know where my A/F was. I ran it richer than 11.5:1 somewhere around 11.
I was pleased to be signed off solo, after only two days of experience (one in october and May 10th). My head barely fit out of the car after the compliments my instructor gave me. I've never done 1/4 mile racing, and I never plan to. This is just too much friggin fun!
I passed every car in my group (white) except a newer 911 Turbo. Yeah 4wd and 2 turbos are slick. In the video you can see him either always ahead of me, or passing me. After actually holding him off (for a short time).... later in the pits the instructor of that 911 came to me and asked what the heck was powering this eclipse ! Well let me see.. Does EVO III 16g mean anything to you ? Guess not. Never mind. 100 octane and let's leave it at that. It was cool to see Tim and Mark there again. That is the only other DSM that was there. Where are all the EVO's ? The GS-T is awesome on an open course like this. My gut feeling is that if I had the same everything and AWD it would be SLOWER. The quaife let's me pull out of the turns nicely. See you guys later this year at THE GLEN !

This is a free link, so there are some ads and whatnot. If you wait out some timer or whatever there is a 100mb video I put there.

Man... what a great track! Actual trees and grass, every track here in the south-west is dry desert. Who was putting on the event? I noticed you said you were running HPDE so can I assume it might have been through NASA? Looks like you had a blast:thumb:
 
Porsche Club of America (PCA) High Performance Drivers Education (HPDE).
The track does ROCK !

Interesting... in SoCal (PCA) won't let anything attend an event if it's not a Porsche. Here there call it (POC) Porsche Owners Club... they don't like getting passed by DSM's :p
 
How thick is that IC core?

In doing road course/time trial heebie jeebies, I've never had problems with overheating with my Apexi front mount with a Koyo radiator, Greddy 13 row oil cooler, and drilling three holes in a 90°C autozone thermostat. I also run a pair of wide holes where the typical "black area" of the front 2G bumper is.

I usually keep the AC fan on the whole time, however as a little extra margin because I'm not running a hood-vent right now.

If any problems I ever have, it's with the 2G rotors that chew through pads within 3 sessions because they overheat so easily with me doing my typical braking style.

Consider running 109 Unleaded next time. It'll help more with timing as well.
 
The intercooler is only a 18x9x2. I'm sure it's the radiator that you have that is keeping things cool. I'm going to have to upgrade that before racing in hot weather. My temps were only elevated, they were not out of control. I do have a air oil cooler in the drivers side opening. Oil temps were always perfect. I have the FAL fans, and they are wired to both turn on when the ecu decides (210deg). The intercooler end tanks block some air flow too. A bigger radiator will do the trick for next year. Or I could try throwing more water down the intake (currently 3gph). A SMIC (thus ditching the FMIC) isn't a possibility because I have a cold air system and water injection there now.

Are you running the 82C thermostat? What's your coolant mix like, like 90/10 or with radiatior relief.
Wrapping the coolant hoses help a bit for me as underhood temperature so high were haeting up as well the coolant. I guess a good and large Koyo would help also and a hood vent.
Just asking but where did you get your WI kit? thanks :)

Around here they have gotten used to it at the track, at autocrosses, at pretty much every racing event around. They are much more humble now. :D

The West coast DSM community is pretty inconspicuous when it comes to any type of road racing… I have been seeing a lot of EVOs ripping up the auto-x’s and time trials in the last year and a-half though.
 
The cold-air intake and water injection are high-quality home-grown DSM late night in the garage built !!!
I should have time in the next two weeks to take some pics of the setup. The shurflo pump is mounted where the SMIC was on a custom plate that also holds an override switch and the boost switch. The cold air intake is next to the pump and routes straight up to the MAF. The windshield tank in the rear is used with distilled water. The fog light wiring is 15amp and since the power was there...when in rome... So the only current drawback is you have to have your lights on for the water injection. I'm going to correct that at the switch internal wiring in the future. It is set to turn on at 15psi. No surging or problems. I'm getting equal timing and no knock to running c-100 ! That's at 19psi with 93octane. I just did a run. Intake temps 50deg stable. 2175hz at 6712 rpm. That is a new high for me I think.... Anyhow very clean install.

Sweet! Yet another dsm on a road course! Just wondering, do you still have your a/c functional?
 
Jaraxle said:
Heck yeah. Why wouldn't it be ?

-Jaraxle
Some people have tempurature problems with a fmic/a-c combo in track day situations. I'm keeping my a/c too! :cool:
