They weren't going to dyno the headers until yesterday or today. They are probably running behind. Something new like this always have unexpected problems.rp718 said:Thanks for the link.
Looks sorta promising.
I'm concerned that Mossy's doing a lot of talking about his great headers, and can't manage to post a dyno chart.
Maybe they DID dyno the motor, and the results are disappointing. Who knows.
The NISMO setup got a 70hp gain? That's gettin' close to blower territory!

If you really believe the NISMO headers alone are going to give you 70 HP at the rear wheels then I have some prime resort property in Florida that I will give you a good price on!
70 - It's probably some sort of French HP rating!92TripleBlack said:Stay out of my house!
I'd guess 20 HP on the Nismo and wherever you saw 70 was a typo. They would be better in tandem with exhaust, intake, etc. but without the supercharger or Nos, there ain't 70 HP for sale yet.
I was thinking of 300 hp to start. You get about 20 HP from good headers on my vette. You get 70 hp from a good set of polished heads and a cam. I see claims for 70hp from exhausts for vettes also. Never seen one dyno for another owner at higher than 20hp more though without lots of other work done first.rp718 said:I'd bet 70HP is wrong too, but that's what the claim is.
Don't forget, the starting point is 305, not 200 - 70 is only 22%.
It all depends on how detuned the stock setup is.
I bet the 5.6 is easily capable of 600HP.
Very steep. However, $500 for stainless exhaust like the Gibson seems cheap. Reverse those prices and that's what they charge for those parts for my vette.3100GPSE said:WOW $1100 for some headers. is it me or does that seem kinda steep?
