Hey Jeff - Very impressive 1/4 mile time there. Nice hole shot too. Are you running drag radials?? Do you do anything to cool the boost down?? How many psi is the blower putting out with the smaller pulley??
Sorry I can't help with your question. I was glad to hear these cars have forged pistons though...
