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
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!! COUGH COUGH!!)
