Well I finally have numbers!
Setup:
4.2 v6 (1998 F-150)
M112 Supercharger w/2.93 pulley
SSM adapter Plate
Mild ported split port heads and intake
Comp Cams 259HR115 cam
Comp Cams 26918 valve springs
Scorpion 1.73 roller rockers
Lightning 90mm MAF
C&L boost pipe
Walbro 255lph pump
Cobra Blue 39lb injectors
94 3.8 v6 stock headers
94 3.8 v6 25% underdrive pulleys
Double roller timing chain

I took my car to Tecmotion owned by Matt in Calgary Alberta.
First, off Matt uses a Mustang Dynamometer (Powerdyne) which seems to be very difficult to produce high number on paper. He figures the number that come out on this dyno are about 14% less than a DynoJet.
If you are wondering about the project car in the video, its a 33? Coupe kit car that is going to be Coyote powered. Can't wait to see the car done!
He also has a Mystic Chrome Terminator with kennebell blower and a extremely mean N/A fox body that runs 9.44? and 0-60 in 1.9?
Problems:
Found a few problems with the car that caused a fuel trim.
1. The Cat(s) are plugged.
2. Oxygen sensors need replacement
Results:
On Mustang Dynamometer
247.8 RWHP
264.4 RWT
As a comparison a stock 3v V8 Mustang does about 225 RWHP on this dyno!
On Dyno-Jet (Estimated by Matt, 14% more)
288.1 RWHP
307.4 RWT
At Flywheel (Estimated by Matt)
330.4 HP
352.5 T
So I'm pretty happy with those numbers! Once I gut the cats (possibly put in resonators depending on sound) and new oxygen sensors I should be able to get pretty close to my 300 rwhp on a normal Dyno.
