Just wondering if anyone knows what the "sweet spot" is for the Apexi (IHI RX6) turbo?
Can it be run at 17psi or is 14-15 better?
Thanks, Don

Sorry I can't be more helpful with something like a compressor map, but here are some actual results I have collected:

You can see that most people run around 14-15 (probably due to the fact that 17 is getting into possible "race gas only" range... but one guy on rx7club.com (Cheuk in Seoul) did do a run at 18 psi. Maybe you should PM him or something...
