finally got to the track with the car, ran into some issues but first pass off the trailer since last year it went 10.85 @ 133 with a 1.95 60' launching at 2800 rpm 2 psi.

2nd pass got all messed up, launched it at 3800 6 psi, front wheels came off the ground scared me a little so i short shifted 2nd gear because im a vagina, then lifted at 1000 foot because i saw it was getting hot. came around to get my time slip pissed off on how bad i messed that run up and found out i pulled a 1.511 60' and went 10.46 @ 129 . . . . .

hahaha well i wasnt expecting that but ill take it proudly! that was the last pass i got, we noticed the car wasnt making anymore boost and had the controller set pretty much full tilt, looked inside the turbo and saw the impeller had no blades left . . . .

so packed her up for the night, but i went home with a smile on my face.
the motor is a bone stock short block, stock lt1 castings, with manley stainless 1.94/1.5 valves and a 220 230 comp cams hyd roller and 15 psi of boost from a gt4202.

we will be heading back up this weekend with the new GT4508 (80mm) and launching it at 4200 rpm around 9 to 10 psi and see if we cant dip this thing into the 9's.

all this is being done at 7000 feet altitude on a 9" slick and a full street car at 3630 pounds.

129mph at 7k feet is no joke, especially at only 6#s boost.

Wonder what will happen first, getting it dialed in, or grenading the motor? . Can't wait to find out!

thanks guys, im trying to get back to the track but the rain is not wanting to let up, ill try and get it out there this weekend or next wednesday. that 10.46 pass was on 15 psi, but only 6 psi on the launch.

its got lots more in it once i turn the boost up, its tuned for 20 psi so it will go 9's if it hooks up.
