i was just thinking of doing a low boost (4psi) with a high setting of 8psi on a s4 turbo running the a stock s4 n/a mani set up and a medium sized fmic, or just put a couple top mounts in series behind the grill since i already have one, and top mounts are a dime a dozen

so i was thinking using this set up:

s4 n/a manifolds and tb
2 stock tmic's in series
stock s4 turbo+mani w/ ported waste gate
cheap motoria 3" downpipe into my dynomax rust back
550 primary 720secondary
fd fuel pump
microtech lt-10s
13b-t front cover swap
2.5" exhaust mani spacer
oil filter pedastal bypass line to turbo
large s/p with s4 na rotors

Ugh anyone think 8psi is too much even with a good tune on an lt10s? i dont wanna run too much and pop it haha

And is 5psi good for everyday?

thanks

the drawing board

umm comments?

 

How are you going to have the wastegate open at 4psi? You will have boost creep with the s4 turbo. And why don't you just use an ebay front mount insted of the ghetto dual intercooler setup?

 

Wastegate spring on the s4 turbo is 6psi I believe. You can't boost lower than that without leaving pipes unclamped or something.

@ Turbo II Rotor. He mentions ported wastegate, hopefully he wont have creep issues.

 

Simply brilliant........

 

Anything less then 8 PSI on that turbo is a massive waste of time.

If you must use the stock S4 turbo, just run it at 10 PSI and be happy.

If you really, really want to run 4 PSI, then just do it on the NA ECU with a bigger set of secondaries.
