I installed a tvs, dual pass with option b and phenolic spacer. I am getting it tuned from Trifecta via Bad news racing. I just received a response from them after sending them data logs:

Looks like there is an intake leak. Were seeing higher manifold pressure at idle than we should, idle is pulsating, and trims are very positive.

You're going to need to double check the install (possibly make sure the supercharger is sitting flush on the intake manifold).

My question is how do i find this leak. I have taken the supercharger off a few times already because of leaks coming from the dual pass. I have not had any issues putting the tvs back on everything seems good. Any ideas or comments?

 

Spray brake cleaner at random spots from intake to intake manifold and u will hear the engine bog down when u hit the leak

 

what he said

 

Try this: take the phenolic spacer off. If you installed it with one OEM steel and one composite gasket it will leak. The spacer needs a composite gasket each side. BTW I have had no positive success with the phenolic spacer on my TVS .

my .02 c

 

the phenolic did not do **** for me the only way you will have a vac leak is if you did not put the green bypass gasket on or what mr powell has mentioned

 

That's wut I keep hearing that the phenolic is nothing but hassle

 

Depends who you talk to

 

Ok guys took the tvs off and put back on my idle issues are now gone, I did the brake cleaner trick and did not find any leaks, going to send trifecta another set of data logs.

 

off topic but did vince charge you more when u put the tvs on?
