ok i just changed my turbo(stock turbo s4). ported the wastegate and opened up the exhaust part of the turbo. i have a turbo back rb exhaust. there seems to be ALOT more hot air coming from the engine bay that i didn't notice before. and my exhaust note seems very deep in 4th gear wot @ about 4500 rpms. checked the exhaust for leaks and didn't find any. anyone have any sugestions? please.

 

**** man, u should be happy u got a nice deep tone at wot lol. as for the under temps. it could possibly be because there is no longer a heat shield blocking the piping but i thought downpipes actually cooled down the under hood temps because more exhaust actually went thru the pipes instead of radiating off the pre-cat. eh, i dont know but it shouldnt be to big of a problem.

 

exactly!!!

 

the thing is before i took the turbo off to port it the heat shield was off the turbo and it was not blowing this much hot air. anyone else can help?

 

wrap the turbo, get a nice efan rad and fmic setup, turbos = heat , no leaks then dont worry, heat sheild wouldnt hurt though
