Steeda UDP
JLT CAI
LT headers with x pipe (cats included)
Axel back exhaust (Magnas, flows, slp)
Bama Chips or Bren 93 octane tune

just wondering?

If you know your RWHP that will also help.

 

Based on what others have gotten I was say more than 313 (headers, no CAI with 91 tune, pro-flow axle back, and no x-pipe) and maybe less than 330 (headers, CAI with 94 tune x-pipe, hi flow cats and performance muffers).

So 325rwhp +/- 5hp

 

mine was 345 with the mods in my signature.

 

was that RWHP or flywheel? and no headers?

 

That is flywheel hp. No headers.

 

350-360 flywheel hp with a custom dyno tune, not an internet tune even if provided by Bama or Brenspeed (no offense its just the truth).

With a JLT intake, Hooker Long Tubes, Jet TBS (and 4.10 gears) I can make 300 rwhp with a good custom tune.

I just had my car on the dyno last week. Basically all i have is K&N intake, Jet tbs, SLP loudmouth and Diablo predator which is now custom tuned. I put down 295hp and 312ft lbs. I would say with those mods you have listed 315-320 hp.

 

I put down 313rwhp and 325rwtq with those mods. Not sure what that equates to in flywheel horsepower.

 

How does one work it back and forth? If you have x in FWHP how much is y in RWHP.

Also remember, these 4.6 make between 262 to 272 RWHP depending on how your car was put together. heck, I think I started out on the low side out of the box, I feel I had a 262 to start with. I had mine dyno'd and not really sure they did a good job, it was a quicky for a quicky price. It made only 291 rwhp with JLT stock 93 octane tune, UD's, Flowmasters. I want to find a quality Dyno and see what I can get now.

 

try a low side of 245rwhp in some cases.

Figure a 15% drivetrain loss from FWHP to RWHP.
