my best run of the day- route 66 in joliet il

r/t- .177
60'- 2.214
330- 6.166
1/8- 9.349
mph- 78.95
1000- 11.985

e.t.- 14.231

mph-100.33

iv had runs anywhere from 14.8-14.5 usually. 1 pass at 14.2

some runs i had wheel hop some i didnt. also my shift from first to second gear loses boost. second gear boost is at 5psi all the way to 6k rpm and then its back to normal 10psi after that.

because there is something wrong with your car, not necessarily you. seems you have boost issues.

I'm hoping that is the case. I am putting on a HKS downpipe and also i want to check that solenoid by the oil pan that i have read about.

The only thing that i dont understand is if the solenoid was sticking wouldn't i have the same issue every time i shift?

Also during the 14.2 pass, the boost was fine through all the gears.

Out of curiosity what rpm do people launch at? Stock wheels, bfg 255size tires. i want to get my 60' down!
