Can you run 2 external wastegates on a single turbo setup?

Can you run 2 external wastegates on a single turbo setup on a ford 6???What are the benefits?Would 2 38mm wastegates surffice on a 250 motor?

[adrianphu123 73]

yes you can, saw it in streetfords or something. Orange XD, plates GMKILR

sorry bro,doesnt really answer what im chasing.

Yes you can and it is done in some more serious combo's.This shows it done and on that very car.

 

 

But this is a $$$ heavy investment based on the amount hardware and fabrication needed to make it happen and in your case no benefit really.

Remember with a wastegate, you're dumping mostly pressure, not so much flow. It would take a serious amount of power to have that much gas going through the system to need a second wastegate.

 

I'll ask my brother if there's a rule-of-thumb formula for horsepower/boost/wastegate size. He's a big turbo head.

I always throught that car was twin turbo'd lol

 

why bother but, just run a wastegate and bov

Yes you can. I am running twin 44mm Tial wastegates on my 4L.

 

Basically, sometimes when using 2 small a gate, it will not hold low boost.

 

Some people also have split pulse turbos and run a gate off each bank of the manifold.

 

And yes, 2 x 38mm wastegates will be fine, but your probably better off going with 1 big single. Easier to plumb and less messy in the engine bay.

on my twin scroll setup i had to run two wastegates, because you need one for each half of the turbine housing.

 

i wouldn't bother on anything else... just seems pointless.

You don't need two, You can run a pipe off each scroll merged into one pipe and run the gate off that.

Kinda like this:

never even thought of that wes, very good idea
