And it loses hp… i think some big gains will be made there once its leaned out. ---

what PSI is this at? I wouldn’t have guessed that it would drop off as much as it does at the top end… :dunno: ---

> [@gearhead](#): > > what PSI is this at? I wouldn’t have guessed that it would drop off as much as it does at the top end… :dunno: It was all done on pump gas so I think jay tuned it conservativly as you can tell by the AF ratio on top end. usually drop in power up top is due to: 1. head/IM CFM 2. turbo CFM 3. thick AF ratio and conservative timing. ---

The turbo is so massive, i would assume its breathing ok (not knowing the a/r and trim). So, must be the timing staying fairly advanced or something. Only reason i’d guess that is b/c in my nova i run a high speed retard to pull the timing back so the 468 can keep makin power up to 8400rpm… im just tryin to learn. sick numbers can only do one thing…get sicker!!! :burnout: ---

> [@gearhead](#): > > sick numbers can only do one thing…get sicker!!! :burnout: …or go BOOM!!! j/k :doh: Congrats on the nice numbers. I’m sure it’s quite easy to swing the back out with that power. BTW, on my MR2, I have the air-fuel ratio tuned to about 11.5:1 on pump 93. That is generally accepted in our community as the best ratio for our setups. Is that what you guys aim for in the 240sx world? Just wondering… ---
