Here's what my 300 pulled at the dyno:



That's with:

cleaned up exhaust ports via dremel
204/214 @ .050 cam
walker downpipe, 2.5" pipe to $17 cherry bomb
19lb injectors at 39psi

33x10.5x15 BFG M/T running on stock steel wheels 4.11 LSD

the red line is the one with the T-bird fan on HIGH.

the other two lines the fan is OFF.

I LOVE a flat torque curve. It means you have power whenever you need it, wherever you are in the RPM range. I particularly like how it slowly rises to a plateau instead of a quick peak and tapering down. Yet another reason to love the inline-sixes!

Just out of curiosity, which gear did you have it in? I'm assuming this is a chassis dyno.

proof there is no reason to rev a 300 past 4000 rpm.

that is a roller dyno, rear wheel numbers.

4th gear, as thats the 1:1 gear.

the stock dyno charts fall off in torque much more abruptly past 2800rpm.

:rockon

Now I have an idea of what to expect from mine whenever I get motivated enough to finish ordering my parts :doh0715: Are you running the stock FPR or an AFPR?

I'm running an adjustable fuel pressure reg.

Stock injectors and fuel pressure would keep up with these modifications, but just barely. A cheaper route would be 15lb/hr units from accel. Stock are 14lb/hr.

well according to the wideband on the bottom of the dyno, the S/D does pretty well at WOT. There is a slight lean spell there. I may be able to up the pressure very slightly and see if that helps.

The idle quality is fine. Part throttle cruise is perfectly fine as the O2 sensor really takes control. No bucking, sputtering, or any driveability issues.
