does anyone know what is going on with the intake manifolds that are supposed to be coming out for the 2.0's? Or even the cobalts in general..I was curious because I've heard of vendors discussing porting the stock ones but no one seems to have alreadr really made an aftermarket one that gives good gains..anything??

 

For the supercharger... there isnt one... Just a ported version of the stock one...

i think it was RAW who was trying to work on one but no one paid up for them to develop it.

If your turbo, hahn makes one.

 

i think over the top performance sells the ported stockers and the single pass. both great options, do a couple searches and youll see a few people make them just for fun i bet you could buy one from someone on here

 

single pass.. really? i gotta find that...

Ive seen 2 or 3 people offer there service to open 'er up... But you have to be w/o your car...

 

im getting the single pass after my head gets port and polished. You wont notice any gains imo with a single pass until you clear the head's bottleneck.

just my opinion but i will be dynoing differences when i get my new head on and then after with the single pass.

 

over the top ports them... 15whp with free flowing exhaust
they can also do the single pass

 

OTT is guaranteeing 15 whp?

 

thats what there testers are getting out of them, but they have full exhaust... testers that did not have full exhaust, did not gain as much

slightly cooler temps also... there is a thread around here somewhere about it

 

i have full exhaust.... lol
I dont believe it unless an ott vendor can vouche for it.

 

search... its on here, ive seen it

i recieved my manifold last week and they did an amazing jo
