We went to the dyno yesterday, my buddies got a 340HP Ford Crate motor in his 93LX hatch.
he pulled 271hp and 294 tourqe at the wheels, But his power curves were not smooth, and his Air/Fuel readings were starting out at 19:1 and finishing at 15:1. I was told that was running way too lean and 12:1 was where it should be.
he's running 24' LB injectors, 65mm TB, C&L powerpipe with 76mm Mass Air. The problem is we have his FPR cranked to 55psi with the vacuum off!!! and that is way too much, but its still running lean
I know the FPR doesnt make that much difference, so what could be wrong? The computer, or the mass air's not calibrated? what should we do...
Oh I pulled 251 and 290 at wheels with no cam, and Iron heads
in my ride
