I just talked to chad not too long ago to inform him of my boost progress. He said in the end they made just shy of 3lbs and had 365lbs of torque at the flywheel. They swapped from their custom Golen cam-grind to a stock grind and it actually made no difference worth noting. Based on those numbers I suspect the 3.2~ more boosts should land me somewhere between 415-425 in reality. Online calculators suggest 440-450.

Predictions-
I have only seen dyno results on 3 strokers. 2-4.6L, 1-5.0L. All 3 were 5 speeds and built with cam and head porting, etc.
The AW-4 auto zaps an additional 5% drivetrain loss.
193rwhp/236rwtq 4.6L 5 speed 2WD ?dyno
202rwhp/258rwtq 4.6L 5 speed 4WD Dastec dyno
208rwhp/280rwtq 5.0L 5 speed 4WD Mustang dyno
expect 10-12 hp and tq less due to the auto trans.
So N/A 4.6L cam head headers exhaust Auto 4WD-
expect 180-185rwhp and 225-235rwtq which is about 253-260HP/317-330TQ at the crank
Not bad considering stock is 135rwhp/170rwtq and rated 190HP/225TQ crank
Sprintex Supercharged- (if charged air temps are less than 170*)
4 pounds boost +20% 218rwhp/276rwtq (307HP/384TQ crank)
6 pounds boost +30% 236rwhp/299rwtq (333HP/416TQ crank)
-the 20% and 30% are conservative numbers
Can't wait to see the actual dyno results.

Now find a dyno, preferably Mustang and not DynoJet, and spend that last $100 for 3 pulls.
