If i want to run 6 lbs of boost should i get a 6 lbs spring or 8lbs spring....Im going to be running an IC so how much boost lost should i expect?
Im figuring if i loose 1 to 2lbs from the IC then with the 6lbs spring, i would only be getting 4 to 5 lbs to the mani? any ideas?

 

Which brand of wastegate is it? turbonetics? Tial? HKS?

 

tial 35mm....

 

depands if you plumb the wastegate line before or after the IC

 

You gotta plumb it properly... The line to the Tial should come off your TB, before the TB.

I have th tial... and with the 6psi spring i made exactly 6psi... however i changed it to the 9.5lb spring and it barely made 8psi.... so i changed it again to the 12psi spring and it made a perfect 10lbs which was what I was looking for...

 

Sorry i should have been more specific...but the waste gate sits on the mani....so im assuming the waste gate is plumbed BEFORE the IC? BTW the kit i have is from MaxRev....

 

TTT

 

he means the vaccuum line you connect to the side port of the Tial 35mm wastegate you tee it off a vaccuum line AFTER the throttle body. like the FPR vacuum line, brake booster vaccuum line, etc. this method will get you the boost you want (i think that's what he's trying to say). you will need a tee to run the vaccum to more than 1 source.
