hey guys i need help choosing a wastegate size. the turbo ill be using is a Borg Warner s362. the specs for the turbo are as follows:
-Compressor wheel Ind. 63mm extended tip
-Turbine wheel 71mm
-.88 turbine a/r
-Flows upto 67lbs/min
-Supports upto 675-700hp
-included: T4 mounting gasket and oil drain gasket
-SINGLE ENTRY INLET T4 FLANGE
-Supports up to 675-700hp

I only want around 350-380rwhp and was told that i could achieve those numbers at around 12-14psi when tuned on a microtech and stock port...

with that said; what TiAL wastegate would you guys recommend?

ive tried to read and understand a bit on how a wastegate works and what i hear is that if your running a big turbo with low boost than u need a big wg... im just not sure if my turbo is considered BIG or SMALL and if 12-14psi is low for this turbo.

 

Johnny Post this in the single turbo section. Way more people with big turbos in that section that can give you advice.

 

ahh thank! you come through once again! lol

 

Get the tial 44mm, i got it with a t78 works great, Other thing is You don't need a big waste gate because you have a big turbo and running low boost, don't forget if u running at 15 pounds there is 15psi coming from the exhaust side after combustion, So lot more flow coming from the wg.
