What kind of manifold was it????

 

Was a DIY Log manifold, usually pretty stout manifolds, first time I heard of one cracking.

 

Put on my SS Autochrome manifold for now, jus to get me out tonight, and well, the boost is spiking like crazy.. What would cause this? Maybe the port where the wastegate meets needs to be opened up b/c it's alot smaller than the old log manifold? I have no clue why it would spike so much, but it hit 20psi a few times, lets just say.. thank god for boost cut

 

The integra's pretty quick.Blake will hopefully be back with a faster car.I say your boost spike is probably due to that manifold.

 

38mm wastegate on a 35mm wastegate flange is probably alot of the problem?

 

That vehicle has a 2 bar map sensor which doesnt read boost past 15 psi hence you do NOT have a boost cut in place....

 

I think Blake had a 3bar if Im not mistaken....

 

Fixed the boost spike, the boost controller was set at 17psi, but the ports on this manifold were HUGE compaired to that DIY log manifold so I guess 17psi on the log manifold was around 20+ on this manifold, turned down the boost a little bit and it stays at 17psi now and doesnt spike at all. This manifold looks sexy aswell

 

Yea it's a 3bar map..

 

Ehm, no you are all wrong. Trust me I would know.
