First 2014 shakedown passes for twin turbo 401
Made 3 hits at street car night. Track was cold and rain was coming late. Struggled for traction 2/3 passes. First attempt was 7 psi at 3800 of tbrake to 20 psi no ramp in. Blew first gear off and let out, ran 2-3 thru 1/8 and coasted out.
Next pass was my best all night. Same tbrake settings but 1 psi or so more boost, plus ramp rate of 6 psi per second. Hooked at first but seemed to unload as ramp came in. Spun top of first thru the 1-2 shift. Then it went straight.
1.49 60'
5.96 123 1/8
9.12 155 1/4

Next pass i tried higher two step launch and 5 psi per sec ramp but it didnt take. Spun 1-2 hit limiter 2-3 and went 9.63 152
Lots left in it. Car was about 3725 lbs with me in it. 3700 even this morning with less fuel and no helmet lol

I got tons of compliments on how this 5" exhaust sounded. Its really an awesome system
If i didnt spin it might have gone 8.99 that night. Track must have been damp. All the cars had condensation on them. Nobody was hooking well

Tons left! Adding a third fuel pump and looking to get a more aggressive race gas tune. Should see 1200 whp and mid 160's. also could drop 100 lbs in exhaust and skinnies

the first pass it looks like you're on the brakes early?

No it was brake pedal not being adjusted far enough out. Dropped at high rpm i think possibly from hydroboost setup and trigger switch to turn on lights? I wasnt on it early that run

I haven't been around in a while. What has changed since you were just cracking high 9's a few years back? I think I remember some 9.70's were your best?
