Thanks! I need a new set of plugs then I'll go back to the track and turn it up. Driving the car every day has opened up the plug gap enough that it was blowing out the spark. Seriously, 485whp should put me in the mid-11s. I ran my actual track numbers in the Wallace Racing calculators

http://wallaceracing.com/Calculators.htm

My best MPH so far is 116mph = 457whp, which is exactly on the money! On 18psi that same day on the dyno it made 450whp. I was running 18psi all weekend at the Pontiac Nats. With a new set of plugs and some race gas and ice, it should be 500+whp on 21-22psi. That would put me 11.30s-11.50s at 125-ish. (COUGH COUGH!! <dailydriver> COUGH COUGH!!)

Ran it through the ringer last night! 11.98!!!! with a best 118mph. I only made two runs, but accomplishedwhat I went there to do! The first run, I red-lighted and slept on the tree, the clock was ticking and I was still sitting there waiting for some reason. I rolled thru the light on the foot brake trying to build boost. But when I saw the red, I just held it instead of going! HAHA! It went 12.60, bit at the 118mph. The 11.98 was 114.5 for some reason. Not sure why the mph was down. I'll post the timeslip later.
