i need help choosing a WASTEGATE!
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.

TiAL 44 will be fine if routed properly. If his turbo is not running a divided housing he can still run a divided manifold with minimal loss. Ideal? No. Noticeable? A little bit. The plus side is it will have the potential to make a bit more power with the slightly larger (in volume) A/r than the divided housing of equal size, Noticeable? Again, a little bit and not worth choosing a divided housing IMO. As a example, We compared two 20B cars we did here once one with a divided housing one without. we were surprised how little difference there was overall. On that comparison we thought for sure the divided housing was going to be a noticeable hinderance and it proved to be only a minor difference.

cause the whole arm leading up to the flange is smaller than the opening to a TiAL 44mm. in that case, wouldnt i have to get the whole arm cut off to replace it with an arm with a bigger radios and 44mm flange just so it can flow the way it should?
take a look. i feel like theres no easy way to do it.

That, is a poorly designed manifold. With the wastegate runner at 90 degrees to the primary runners, you're going to have boost control issues regardless of the size of wastegate.

f*ck sh*t d*mn b*lls... uhhh looks like im going to be shelling out 750 for my mechanic's manifolds than
aaron, the one i have is considered a short runner? if my mechanic's is a long runner, are there positives and negatives to either? can anyone elaborate? since my search on that answer in other threads usually seem to turn into arguments between two sides ;/

well im looking for a "streetable" car and im more into autocross than dragging so response is definitely priority.
i read that short runners like the one i have are typically more responsive where long runners can net you higher power levels. i know my mechanic's long runner is divided so maybe it can still help spool? wouldnt you think so? sorry for noob questions lol

Being divided will help and it's more complicated than just short will do X and long will do Y, there is number and type bends involved along with tube diameter, size of turbine and turbine housing etc. Usually on here people are comparing their apples with your oranges and it gives you a peach for a result.

i did end up dropping the doe for my mechanic's manifold.. but im still curious to why the one i have isnt ideal? cause i may still want to put it on another less serious set up or is it not a manifold you would recommend using at all? thanks
