Default Went to 1320 Friday, how'd I do?

Friday, I went to the 1320 at Bradenton. I can't find the receipt we wrote the numbers down on, but out of about 4 runs, I managed to get a a few mid 14's and two 14.1s. My trap ranged from 99-105 and my 60' was about 2.2 -2.5. If Jordan still has the receipt, I'll post the exact numbers. My last 2 runs were getting better because I finally figured out how to launch without a lsd. My mods consist of a fmic, a bov, 3" exhaust after the stock turbo outlet pipe, and a manual boost controller.

Now, for the excuses. I wasn't holding boost well. The boost control was set at about 14.5 psi and it would boost to about that and then drop/level off at between 9-11 psi. I understand the t25 can't hold that much boost, but I don't think it should drop that much. Could my bov (Greddy S, vented to atmosphere) be causing this? I believe the turbo is going, but other blame the boost controller. The reason I do not suspect the mbc is because it has worked perfectly and held boost on a mr2 turbo, supra tt, fd, and gsx. Then again, all of them had a stock bov which was recirculated.

Hopefully I'll have the boost problem sorted out in time for the next track day. I should also have some stickier street tires (not the all season tripe I was running), along with wider wheels and some other stuff by then.

Sorry for the long post,
Johann
