Oh it's possible. I made 473 at the wheels and when I had the 5-speed I ran a 10.90 @ 126 on 11lbs of boost. With the auto and running out of gear way to early it went 10.59 @ 129 or so. You just need to work on the suspension and run more tire psi.. You are all overt the track and simi bog off the line because of your low tire psi.. Try 13-14 next time. If it spins then go down a 1/2 until it hooks. Mine likes 11-12.
