Just thought I'd introduce myself, since I will be needing a lot of help. I'm Rich, the slow old poop.
I sold my 3000GT track car and bought a 1990 Eclipse GSX that was built to run One Lap of America in 2003. I plan to run it in NASA events. At the moment, it is a very streetable race car, getting 28 mpg on the highway.
It has a built motor, roll cage, StopTechs, Ground Control, and all the usual mods. It runs 21 psi on pump gas and (allegedly) 29 psi on 110 race gas. We haven't been able to get it to 29 psi yet (see below).
First track day at MidAmerica Motorplex (MAM) near Omaha, we blew off the oil filter (running 120 psi oil pressure requires running Wix filters, not the spare Amsoil filter that came with the car). The seat was all screwed up, and I had to drive the car with my head cocked to the side to avoid the roll cage. We discovered some serious boost leaks, which required replacing all the intercooler hoses and welding up an intercooler leak.
Second track day was again at MAM, with a bunch of guys from Minneapolis who rented the track for hot laps. We had planned to kick the boost to 29 psi, but it rained most of the day. In the rain, we kicked butt, passing some cars twice in one session. When it dried out, we just ran it at 21 psi.
Next up was the drags. We turned a 13.4 at 105 at 21 psi, but I am not a drag racer and kept hitting the rev limiter, which kills about a second. I am guessing that it is a mid 12s car at 21 psi. The big problem was that we could not get the boost up much higher than 23 psi, even with the boost controller wide open.
This past weekend was as an instructor for the 3000GT national gathering's road course event at Gingerman. We got another manual boost controller, but still could not get the boost up over 20 psi! As the day wore on, boost dropped off to 18 psi, with lots of sputtering. Got plenty of track time though, and the car ran well otherwise. Looks like we gotta do some more boost leak tests before we go out again.
We continue to sort the car, as we await the first available NASA event. Got the boost leak, problems with the brakes (see my other post), and crummy Dunlop race tires to fix/replace, but the car appears to be built properly, runs strong, and is reliable. I will keep fellow road racers apprised of whatever progress we make through the year. We'll be running NASA time trials this year, and plan to run the races next year.

We have another DSM doing some real driving. What type, size, etc., tires are you running? Doing the time trials will really help you to hone your driving skills, especially when you start racing and need to qualify.
