Modification Update
Okay, after installing headers/exhaust, air intake, inter cooler, new k27/29 turbo, Tial 46mm (1 bar spring), Patrick Motorsports Clutch and LWFW, Leask WUR; keep in mind that this is the first run out of the box, still needs some dialing in; she produced 352 rwhp at 4800 rpm and 436 ft/lbs at 3400rpm. She is a little rich below 3500, at 4000 rpm AFR is 11.44 (ideal) then she starts to lean out to 12.75 AFR at 5000rpm (shut her down after that).
I'll try to post up the dyno sheet later today. I think we need to work on the timing (too much torque?) and add fuel above 4500rpm to keep her under 12 AFR. We also need to dial it down (fuel is at 10 AFR or so) below 3500. I think if we dial it in, we can achieve 375 rwhp/400 ft/lbs. Any thoughts?
Motor is a stock '79 3.3, all new hoses, oil cooler, spark plugs, plug wires, etc, etc.
