Here is a shot of the completed exhaust side of the motor. Still need to build the bracket to support the turbo and the Airbox. The airbox will come this week. I should be okay on the bracket for dyno runs. The turbo is tapped at the start of the scroll for the boost controller. The fitting on the lower wastegate is a M12x1.5 to AN4. The hose end on the top of the wastegate is a clamped end type. The top of the 2nd wastegate is currently plumbed to to the intake manifold. It will open and close, but it does nothing since the 2nd wastegate is capped off

Plenty of high horspower cars run dual wastegates... its not all that uncommon. I see setups like that all the time.

For instance, Dual 35s are far less expensive than an equivalently sized 46mm tial. Also if you look at the GTP cars of the 80s, they often used dual wastegates. This is a fairly common technique for controlling boost when huge wastegates are impractical, whether it be a size constraint or price.

Thats an answer I get from friends.

it can also be used as an anti-lag by letting fresh air enter the ehxasut manifold
