i tried to raise the boost past 9psi, but it would lean out way out of range. so @ 9psi was the best air fuel ratios.. left it happy at 9lbs..

I was unaware the stock ecu could run an extend port or larger secondary's. Nice work though!

I am amazed at this, your making around 100HP over stock, just with upgraded exhaust, fuel, and porting.

best part about this is. this amount of hp is enough to keep most of us happy in a street car. not much went into achieving this hp goal. ofcourse some people want more, but the average rx7 enthusiast would be very happy with a simple set-up like this. I drive this rx-7 once in a while (when my kid breaks an engine mount, and drops it off for me to fix it) and i could tell you it's a fast and great car to drive.

Is this the same car you put in the other thread that ran the 13.0 at 104mph?
