Also Someone should go back drag times / myslips and compare all there back 1/8 times. subtract the 1/8 mile et/mph from the 1/4 et/mph to see what the car "picked up" in the back 1/2. I think it's safe to say that the back half is almost all car and not driver. that way you can do a comparo factoring out the driver.

I've said it before, I think it's ALL in the tune. I'm sure the timing on the tunes the larger pulley's are seeing is basement level. Add to it the ecu is probably pulling out more timing because of charge air temps. I'll bet almost anything a 185+Sunoco+more timing would be the answer for some smack down times. My statement is further backed by the substantial gains these N20 cars see. the N20 cools the Charge air to the point the ecu starts adding timing back in to complament the larger pulley.

Stop chasing boost, 1 degree of timing is worth way more then a pound of boost...
