Your down pipe is too small

Got to the track yesterday.

I was being a big baby at the line and never launched hard. Best time was 11.88 @128mph, just under 15# of boost rolling start 2.40 60'. Truck weighed 3700lbs with me. Shes got more in it, messing with the tune and launching harder.

Number 860

Nice sleeper! You can barely make out the turbo sticking out thru the black grill.

What type of fuel tank/fuel pump are you running?

The tank is junk yard special 99+ V6 camaro, Fuel pumps are a walbro 400 and a walbro 255 "Y"'d together to a -8an feed line. Both pumps fit inside the stock bucket

67-72 Chevy trucks
 

Nice truck. Nice woork on the turbo setup also. I just had a 6.0 put in my 71 but no turbo. Hope to get final tune done the end of this week. Having the 2.5" pipes and mufflers installed now.:D

I pulled the old girl out of winter storage. She's ready for summer

Finally put her on the rollers today. It was impressive and scary all at the same time.
I was very happy.
