Headers better et's?
 

i just put my QTP and a ory on. Iwent 13.2 @109 with some other bolt ons, the only thing new is ssra ram air, QTP's, ORY, SFC, and LCA. My 60 fott went from a 2.1 to a 2.0 but i ran a 13.1 @ 108 shouldnt the headers help me out more then that? :confused: It alos may have been a crapy day to race a little warm.

the weather could of played a huge role in the discrepency....if it was say 15 degrees warmer then yes, the headers effect was negated somewhat by the shitty weather. are your tires worn more then last time? more gas in your tank? you on nittos, if so, did u let any air out? you gain some weight? :jest: lots of things...

True, what was the air/weather like when you ran the 13.2 before the headers went in?
Also driving style/skill, you're making more power now so you might have to change how you race it a little bit, your 60' still improved so hopefully you're not losing too much traction due the recent power gains.
The car will improve as the weather gets cooler and your driving improves, a 6 speed car can be all over the place, it's very driver dependent. :drive:

well, if you just put them on it seems like you didnt tune, my guess would be tune it up and get your A/F straight and head back to the track.

With a air lid, slp-sfc, ftra, pro 5.0 I went 13.44 @ 108 2.23 60 foot

With the addition of headers, true duals, LCA's, PHB and Shaner S2 throttle body. I went 12.94 @ 110.x w/ 2.13 60 foot. I expect this to drop to a high 12.8x when the weather cools off, still on street tires. My car has not been tuned.

Lt's made a huge difference for me. :D
