I needed clutches with a 3.85 Pulley (Went 10.08 @ 142). That should be around 800-850whp on a cold day with 22 degrees of timing. 1/4 mile time depends on a lot more than just power, other mods need to be factored in. I’m on a 3.5 Pulley now (850-900whp with 22 degrees) and in the fall, hoping to be going mid to low 9s with stock converter. Best 1/4 is 9.88@143 in 3000+ DA. Highest MPH is 148 in 2300 DA.

Not really, clutches were slipping and my launching wasn’t very good lol. What half shafts are you using and how you launching the car?

Stock shafts, but do have r lock.outs and end links. Going off idle with a foot brake. With my pump gas tune, I tried leaving at 1200, 1000 rpm and the car was slower

Congrats,what race track were you running?
Hey David,
That was at woodburn 2 weeks ago. A group of us were roll racing in Bremerton Saturday and drove down Sunday morning. They have been really cool about me running over135mph. The 9 sec pass not so much. After my first pass they told me another 9 and I'm out. To bad too. The next run my 1000ft was faster but had to get out of it. Car might have a 9.7 in it. PIR is open this weekend. A group of us are shooting for the 8/7 weekend there. Have you been at the track?
