RWHP Guestimates?

I have a 2006 Mustang GT with a few mild bolt ons and a larger cam:

Stage 3 SPR XFI Comp Cam
.237 .244 .547 .560 @.050 Degree @112 LSA
Comp hardened valve springs
Phaser 20* Limiters
FRPP Intake Manifold
IMRC Motor / Runners Delete
SVT 44# Fuel Injectors
Walbro 255LPH Fuel Pump
JLT Series 2 Cold Air Intake
Brentech Twin 62MM Throttle Body
Pacesetter 1 7/8ths Longtube Headers
2.5in Full Exhaust
Custom Xpipe
Muffler Deletes

Anyone know what kind of power it SHOULD put down through an TR3650 with factory 3.55 gears?

Okay good to know. It made 371 in Texas 101 degree weather after being dynod for 6 hours. So I figure it could make a little more in some cooler temps with less time on the dyno. This was also on a Dynojet dyno.

When I got mine dyno'd, the guy showed me how there are 3 equations on how they do it. Pretty cool. They adjust to air temps and humidity. So you might be right on with the #'s.
Either way 371 is great

We had some problems with my aftermarket throttle body not opening 100% throwing us through loops so spent alot of time swapping parts on and off the car. The car was Dyno Tuned by Manny Alvarez at Hpp Racing in Lewisville Texas. Guy is an amazing tuner. Ill post up a graph. Found out I have to do a little port and polishing on the intake manifold now though

He said he thinks the dip in the graph has something to do with the manifold / throttle body somewhere. He said we can port match it and see if that eliminates it. Its not in the cam. And never happened until the manifold went on. So thats the only logical answer we have found.

Yeah no joke. 370 seems quite high for those mods
