Mustang Dyno numbers stock
298 rwhp 302 wrtq
lt headers and tune
313 rwhp 323 wrtq
I then installed the B2VR and could feel the diff.
Oh, I also have the performance hood seal!

Any CAI + LT's should be good for 30-40 rwhp so that'd be 35-50 crank hp.

Manufacturers only list flywheel horsepower as actual wheel horsepower is influenced by TOO MANY variables such as:
Chassis dyno used
Ambient temps
Elevation
Drivetrain
Condition of engine
and probably some other factors I can't think of off the top.

Prior to having the head/cam install, I had my 99 A-4 dyno tuned. It went from 299hp to 326hp. I had a twin cone intake & corsa pacecars. Torque went from 291 to 328. The best $300 I ever spent.
When I first completed my cars about 7 years ago and made over 500 hp, those numbers were pretty good. Compared to what many modded cars are making today, it's nothing.

HP vs TQ
There are too many variables, yet one factor that is missing is "Torque". You see, the closer the HP = TQ makes a Huge difference in performance.
Yes there is a large difference between B and F Horsepower because of the load. The LS1 is equal in 350 HP and 350 ft. lbs.TQ. That said, when your at
1/4 throttle to 3/4, the response is extremely precise and almost chilling.

Better math would be
315/0.85~370.6 hp
the 15% conversion factor for manuals needs to be factored in by divisor rather than multiplied.
but you got the right idea
Also, It's my belief that GM used that crappy 4 3/4" hole breathing stock air box to get the LS1 DOWN to 345hp(I've seen it posted on the forums as well so I won't take all the credit), as soon as you remove that terrible flow restriction, you'll find most people can pick up 15 rwhp just from a true CAI.
