Building my own ignition.... - Page 2

You should be above 200 WHp by 7,000 rpm. The old engine in my car did that with a cleaned-up stock port, factory manifold, factory ignition, and 8.2:1 polished turbo rotors. I also use a mustang dyno - you can't improve on steady-state loading...

I think that the carbs are running very rich. I always had trouble getting a carb to run at all with vacuum if I leaned it up enough to make power at WOT.

I really like fuel injection.

Still, there is something to be said for old school.

It is running perfectly fine as far as AFR's go. We had it hooked to a wideband on the dyno as well. If I remember right it was in around the 12's or 13's. The big problem is the carb and intake. A 48IDF is too small for the engine its on and the intake isn't the best flowing intake ever made. Also my exhaust isn't ideal for power. I traded maximum flow for my hearing.

The first exhaust I built for it made far more torque down low but I just could stand it and neither could anyone else (like the cops).
