Sounds like a boost leak to me.....Boost leak test it
Ive got a 306ci with the F-Cam. Great power and awesome drive ability
Yup I dont see any issues with the orientation it is mounted. If you have concern with the water building up over time, just drain it every month...
The E is designed for supercharger apps....But I have heard of a large number of people using them in Turbo applications, and have made good...
I like the single set up....Less things to buy and a prettier engine bay to boot.
I have at PT72GTS with am .81 exhaust housing. I put an Ebay T4 blanket on and is still somewhat lose. I would try the T3 if I were you.
Never heard of it before, but very interested to see if it works.
Looking forward to this site!
