New Mustang Dyno numbers...
New Mustang Dyno numbers... Yesterday afternoon after the fuel pump episode, we made it to the dyno for tuning. It was a long afternoon/evening. We started w/ about 355hp / 363tq, by the end of the night we were at 390/390. Since the fuel line in the pump is screwed, it was startving for fuel. The pressure was dropping to 40# at WOT. We never got the A/F better than 13.7 @ WOT. It had a nasty miss throughout. For as bad as it was running, I was both impressed and dissapointed. Needless to say, we didn't get to spray the 175 at it. We had to change the line again before we left the dyno.
Mods are:
Comp 220/224 530/534 112*
Comp Pro-mag 1.85 RR (made cam 581lift)
PP S2 5.3 heads
Weiand Aluminum intake (port matched)
Ported MAF and Tbody
SLP Lid w/K&N
March Crank Pulley
Taylor 10.4mm wires
Hooker LTs
Lane's 3" X-pipe w/ twisters and turn downs before the axle
Moser 9", 35 spline, detroit locker, 3.70 gear.
RAM VDS 910 clutch
All the suspension stuff.
160* Tstat
There's a ton of other stuff I know I'm missing.
When I get the miss worked out we'll be back on the dyno. We're hoping for more than 400 on the Mustang. I would be satisfied w/ that since it's such a small cam.
Oh.. the race weight was 3685 w/ me in it. For someone needing a race weight, the only addition was the Wolfe cage.

The raceweight was 3685# with me in it. They added an extra 160# for the driver. My tuner took my place in the co-pilot seat. The only thing not accounted for was the wolfe cage. I have to find the miss and we're headed back. I think the fuel rail and the NOSzles are coming back off. I hope to do some more tuning this weekend.

Those #'s are AWESOME at that raceweight. On my last mustang dyno run with my old setup I netted 400rwhp/387rwtq with a much larger cam. The raceweight we used was 3700lbs. This was with cutout closed. 
My old setup was old TEA Stage I's that flowed 290cfm at .600 lift and I used the MIGHTY FMS-9 cam. I am surprised more do not use this cam. It is awesome and idle quality is great.
