About 5 weeks ago I blew a head gasket at the track. While I had the heads off I gave them to FrankG off of this board to do some work to them, ie. port, polish the combustion chambers, back cut the valves, new springs etc..
My previous best with the RA 93 chip was 12.35 at 110 or so and my best with the RA 107 was 11.90 at 114.9. 23 - 24#'s of boost.
Tonight with no other changes then the heads I ran the following times with the RA 93 chip and 112 octane. Same boost levels.
run 1---------12.10 at 114.7
run 2---------11.99 at 113.7 (I let it cool down a little longer)
run 3---------11.91 at 115.6
run 4---------11.82 at 115.3 (after this run I was told only one more run then I had to park it because I have no roll bar)
run 5---------11.76 at 115.76 with a 1.68 short time.
I wonder what it would have ran with the race chip and 116 octane!
