i was wondering right now there is a 10 psi spring in the wastegate. if i want to run less boost with a manual boost controller,and just turn it up when i want to do i have to get a smaller spring, like a 5 psi spring???

Thanks!!

 

sounds right to me. Throw a 5 psi spring in there and then the boost contoller will hold the spring shut until the psi you have chosen. I was looking into the Voodoo Boost last night.

 

yep thats exactly what you need to do.

 

That's the only way you can run less boost (change springs).

 

You will only be able to run about twice the spring pressure in boost before exhaust starts pushing though.

 

so basically a 5 psi spring will yield 10 psi max??

 

with boost controller of course

 

roughly, yes.

 

ok thats what i thought im new to turbos so i kinda didnt think i could use a 10psi spring and get lower boost (matter of physics) thanks!!!!!!!!!!!
