Twin Turbo- Single Wastgate I know nobody likes SS Autochrome but they have a 60mm v band wastegate on their ebay site. Anyone use a twin turbo / single wastegate setup (of any brand) ? Seems like it would be more efficient. Its not a race car.

On this particular application the turbo's are side by side (opposing) in front of the motor.
Wastegate would be 2 into one inlet and 1 into 2 outlet (does not have to be) as well.

I've seen it done, but I'm sure you could pick up a pair of ~38mm gates for a decent price. I think 2 would be more efficient and for a street car, I'd want the option of getting boost as low as I wanted from in the cabin and no worrying about creep or anything.

its doable. I would be pretty neat looking if you route it nice and put the wastegate up in the center all nice and pretty. I'd guess a big 60mm would work ok since the rest of your setup is so efficient....Jose will be on here soon, he would know for sure.

it would be more of a headache to merge the wastegate pipes to one pipe for the wastegate.
you could probably pick up two wastegates sized well for your twins cheaper then that single gate (how much is it like $300?) so you should be able to pick up two smaller ones for $150 even if you have to get cheap ones.
doing two will be more simpler to route, plus it will probably save space, so there is no advantage to using one in your case that i can see.

Not a good idea to do, but it can be done. Like mentioned, go with twin 38 gates. Also good luck with those SSautochrome wastegates.....they are pretty much garbage. Makes for a nice paper weight though.
