New numbers just diffrenet short block (same compression) new heads and catback dyno numbers:

670rwhp 608rwtq SAE 11psi 14degress of timing 10.9 A/F Ratio
both old & new numbers were on 91octane so this time we detuned the car alittle to 655-660rwhp just to be on the safe side.

Damn nice! Congrats on the new power! Im betting she hauls out pretty good!

 

Thats some nice gains for just heads and cat back.

 

Is that car getting tuned in the "matrix" world or is that a monk? Weirdest outfit ive ever seen in a dyno room

Congrats man! Looking good! Good gains off what seems to be a decent flow increase. I'd like to see a before and after Lb./Min comparison....she obviously flows much better! lol

 

Quoted that from your "estimated gain thread" Damn I'm good, add that 1lb of boost and I'm right on the money. Congrats!

 

Thanks man yes she does flow much better

Thanks man very soon I'll post a thread about estimate power gains with 20psi

 

How do those Nitto 345/30/19 hook with the new power?
