i Have A 2007 Cobalt Ss 2.0 And All It Has Is A Cai On It But Everytime You Wind 3rd,4th And Sometimes 2nd Gear Out And It Gets To Like 5800rpm It Starts Making Like A Rev Limter Sound And My Boost Goes Down To Like 5psi But The Rpm Is Still Moving Up To 6500 But Very Slowly. Does Anyone Know What Is Going On With It? Or Has Anyone Ever Heard Of This Happening Before?

 

might be a bad seal from the intake to the manifold

 

I think most people I hear have this problem have bad seal. I'm not sure what the official term is but something to that extent. I could be wrong though.

 

maybe boost bypass is bad or not working properly.

 

Yeah, sounds like a seal problem, something isn't right with the intake. I would go over it with a fine toothed comb and tighten everything up that you can tighten and see if that helps.

 

not sure what the problem is....but wrong section and loose the bold

 

well thanks for the advice everyone except mike25. i will tighten it all up and see if it helps/ and mike25 the topic said i need help and seeing as how you didnt help you are in the wrong section.

 

lol...i guess this is welcome to another smartass on the board....not in the wrong section.....this is a forced induction related section..and your question isnt hardly about boost...was simply saying that its not in the right section...you would have recieved more help had you posted it in the right section

 

hey mike i didnt post that last comment my brother logged on and checked it for me while i was at work. im soo soo sorry he did that, but im not a smartass.lol. but he is so where do i need to post it at?

 

LSJ Performance Tech would be the ideal section to post this in.

 

its cool...wasnt sure what was up with the random post...yea the lsj performance section is the best place...itl def. get alot more attention

 

ok thanks
