Got the headers on the car, and dynoed with my sae software program, which before the headers the car dynoed crank hp @ 420 hp & 358 tq which was advertised. Now the car dynoed @ 470 hp & 376 tq the inox headers really improved things as i thought. All things being equal with the loss to the wheels being about 15% hp if figure now the car makes about 400 rwhp.

 

but this is w/ forced induction. Correct me if I am wring but the power increase on a NA car will be much less?

 

Brian,From your post I take it that they were ok.
Thanks for your business.

Neil sent some for a few customers out here and for the price they're darned good. Well made and they fit sweet...

 

Sharky your check is also in the mail,

 

Um no it isn't:P That would be the other way around

 

I just installed a set of the INOX Headers from Orton Performance. They bolted up easily, sealed great and there was a noticable difference in the zip to redline. The car feels both more powerful and it definitely revs quicker which I love! The sound is just a bit louder, especially through the midrange and at full throttle, but it's not annoying. The bang for the buck was awesome.

 

UH...50 hp from headers...I must be in lala land.

 

You and me both...

 

Are you NA? What other mods did you have when you installed them first?

 

I am NA. I have an Evo intake and a Porsche Sports Exhaust. I will be re-chipping next and that will likely be the extent of the power mods on the car as my father will be picking it up from me in the near future... I'm not sure what I'll wind up with next...

 

please get a REAL dyno run. the numbers are waaaaay high for NA and are still high for a supercharger, especially since you have a 3.4L.

i have a feeling your input numbers for your software is wrong.
