[QUOTE="93_408_LX, post: 13526820, member: 76780"] I took the car back to the track this weekend for some heavy abuse. We made 24 passes between the 3 days, all in the low 9s. The major change to the car were changing the gears to 3.73s from 4.10s. We attempted to jam more boost at it, but regardless of what boost pressure we commanded through the controller it would not hold more than 21-22 psi. We believe the fairly long and "bendy" 3.5" exhaust is restricting the turbo, causing a backpressure issue forcing the wastegate open. The boost controller is only the single-solenoid FAST controller, so we feel an addition of C02 or a better controller would also help. I'm going to try and build a 4" exhaust for it and change the controller by next weekend to hit it as hard as we can! Also, the rear suspension does not seem happy on any of the passes. It's a light car at 2900lbs with the majority of weight up front, currently the car has 200# 12" front springs, 110# single adjustable rear shocks, these passes were near the soft end of the adjustment. Any advice on what spring rate or shock settings to use for this thing would be appreciated! [youtube_browser]sYgr1Wss0W0[/youtube_browser] [/QUOTE]
