Previous best ET was 14.97s. My 2004 average times were 15.0x and average speed was in the 89-90mph area all last year. Results with just the addition of Y303 heads, FRPP wires, Accel cap and rotor, and AL3924s:
----->1st run----2nd run----3rd run----4th run
60'-->2.208-----2.206------2.165------2.090
330'->6.215-----?????------6.176------6.048
1/8-->9.575-----9.563------9.522------9.355
mph-->73.60----73.95------73.95------74.85
1000'->?????----12.456-----12.414-----12.217
1/4-->14.913----14.885----14.841-----14.623
mph--->93.12----93.20------93.33------94.16
The ???? above was were there was no data on the slip. Don't know why for sure.
I ran with 275/40R17 BFG DRs @ 18psi. I think with some more practice on the DRs I could knock off a couple tenths. The weather was around 70* and humid and the track was in pretty good shape. When you correct for the 2700' elevation the best 1/4 Et is 14.15s @ 97.35mph
Overall I am very happy with the heads
