Okay, after my ITR Intake Manifold was installed, I am not building any boost I used a new Hondata IM gasket too. The car idles fine, and i retorqued all bolts and check all vaccumm hoses... tried spraying wd40 b/t the IM and TB, but did not see any differences in idle. What could be wrong??

Also, can copper spray be used on the hondata gasket? Would that be advised?

TIA

 

what do you have SC or turbo?

 

Turbo... i hear a hissing noise when the motor shuts off... i can't distinguish where its coming from, but the car idles and drives fine... just wont build any boost...

 

what kind of vaccum reading do you have at idle

 

-500 mmHG. I believe it was the same prior to the install also...

Could vaccumm hoses that are too long, or have too many tee's attribute to this?

Yes.. I am going to say it is a problem with your vac lines. The BOV could be stuck open or even the W/G. Find out wich one it is then go from there. Also check all your intercooler piping for leaks

 

just check everything that you touched while taking off your manifold...retrace your steps...because the car is idling fine, i doubt it would be a vacuum leak and in order for you to not build ANY boost, you would have to have all the vacuum hoses disconnected...maybe the charge pipe that connects to the tb? blowoff valve stuck open? what do you have the boost gauge connected to? does it sound like its boosting? could be a lot of things man...
