Slant 6 Turbo 68Dart Project

yes you can do it in park with the throttle linkage. at idle its not gonna be doing much of anything. its only when revved hard that it will start to build pressure. hold your hand on the opening that the air comes out of on the turbo. block it off completely. rev it hard.

I covered it up and crimped the wastegate hose so that wouldn't leak. I pulled the throttle hard but no air seemed to blow on my hand, and I could leave it there willingly without it being forced off. I did feel some nice hot air coming from between the manifolds, but I'd think even with that, I should get some pressure. But nada. The compressor wheel spins, and everything is doing what it's supposed to. I can't move the blades in or out, and there's no play laterally either. The turbocharger as it sits seems like it should function wonderfully.

Exhaust leak that's too large?
