i just ordered a steeda cai for my gt... im just curious what increase i should see with my headers, h-pipe, high flow cats, and cat-back. they all say 10-12hp but maybe i could see more?

 

My best friend took an automotive engineering class here and he was told by his teacher that often when you start combining the bolt ons the gains are less than if they had been bolted on to an otherwise stock engine. Don't know how accurate that is, but that's what I've been told.

 

I would have thought the opposite. I figured the more you had done the more each thing would do since your car would be more efficient to begin with. Who knows though.

 

get yourself on the dyno now....

then get back on that dyno after.....

 

I could dyno it but that costs money to go to a performance shop lol. Kinda on the opposite end of the money tree. But would be the best way to tell lol.

 

shes in and she fits like a glove

 

Looks good!

 

Now for a new plenum and TB.

 

well hows it feel!?!

 

it feels lovely lol. i chose the steeda CAI for its engineering... yeah its only a tube with a filter but it has one less 90 degree bend than the competition. and the filter is massive. i have to drive her from south florida to virginia today... should be a good time! i always loved the sound of a CAI. the way it sucks the air and does it loudly! it really dresses up the engine bay. The Plenum and TB are next. probably a 75mm TB. eventually i want to supercharge it. i only want to build it once... you know what i mean!
