40mm Tial External Wastegate too big for an E316g?

I already have it, but I have heard a few times that it is too big. It is highly doubtful that I would get rid of it since it's already in place, but what negatives can I expect?

Thanks

The bigger the waste gate the more control you have over boost. I dont think you can go too big because its supposed to open at your maximum boost and relieve excess pressure if you boost over your set limit. As long as ALL your boost doesn't drop off when it opens i think your good and i highly doubt you would loose all your boost when it opens anyhow. lets just say you wont EVER have to worry about boost creep.

Lol, ok. I have always had the same thoughts you had on the matter. Thanks

I'll go ahead and say this is *somewhat* true.

The bigger the wastegate, the more control you have over low boost. The function of the gate is to open fully when your maximum boost level is reached, the slowly close as the RPM's climb and the engine gobbles up airflow. If the gate is too large, too much exhaust will continue to bypass the turbine wheel- and the boost level will trail off as the RPM's climb. If you attempt to combat this with stiffer springs, then the opening of the gate can be delayed and cause a sudden spike/drop in boost which makes tuning a nightmare.


These new giant 60mm wastegates are designed for high-displacement engines at very low boost levels. With a DSM at 30+psi, a 38mm gate is all you'll ever need.

Thats kinda what i was saying about loosing boost, and exactally why i run my tial 38mm, jonesin to see how the hx40 performs, trevor at shep was sick while working on my trans and that extended my wait
