Thanks for the replies.
Thanks All for the replies. Thanks SuperRunner for the FP warning, I appreciate it. On GT Race Gas I am looking for 425rwhp with the little blower @ 8 pounds boost, 475rwhp with one nozzle (.021) of NOS, and 525rwhp with two nozzles (.021 + .021) of NOS -- on a dry NOS set-up ECU triggered on at 3600 and off at 5800 (shift trans at 6500 - to save the A342 trans on the 1-2 shift). This should be at the limit, I believe, of the Aeromotive A1000 fuel pump . . . and my 565cc injectors. If, or when, I race with E85 in the future I will have to go with bigger injectors and a bigger (or additional) fuel pump, that's for sure - - - - and a stronger bottom end (I have another 1UZ). I am thinking of blending the GT Race Gas with E85 to produce an exact/reliable E50 . . . the best of both worlds (anti-knock AND anti-pre-ignition).
I didn't want to cut the pistons to lower compression here, nor did I want the expense (on this particular motor) of forged pistons. The chamber machining and polishing cost me about US$75.oo - in Thailand. I did the chambers for a second reason other than the compression after taking to some road racers who do this: detonation. They run N/A with 13-14:1 compression and they knock with the chamber humps still in . . . . and don't with them out.
Anyone else been waiting for their Cometic head gaskets? I am looking into the copper head gaskets with embedded steel rings - are these available for the 1UZ? Anybody use them?
