Default thought i would share

stopped by PDX while Tim was mocking up his new dually wastegated twin scroll setup-....dually?:huh:
TwinscrolledHS37R
Two Tial 38mm wastegates
Onto the porn:

the smaller inlet is from a Green








37 twin scoll hot side
40 inlet picture`d, soon to be 42 inlet.

what is really cool IMO, is that there will be 2 wastegates, one for each bank.


on the 37/40 Tim made 600whp with a simple Perrin manuel boost controller, with the Dtek i think he upped it a little more.

this is a 700 dollar turbo, lol...


non ball bearing, weird flange on the exhaust side....

with the 42 inlet i would assume 650+ and he will probly run NOZ to spool it so we shall see....

2 external wastegates... wow. Where do they hook up on the pic, or is that the "old" header set?

You know, I had never really given any thought to how to go about doing an EWG on a twin scroll.

twin scoll uses both banks of the engine to scoll the turbo, it keeps them seperate, thus utilizing them more efficiantly.


useing the dule exturnal waste gates on a suby has not been done befor, to my knowlege. so this is going to be pretty cutting edge right now.
