dual wastegate using external and internal?
I've had this idea lately, since I have a T3/T04E with a internal setup, and a manifold using an external, why couldn't I utilize both simultaneously to prevent boost spike? I could just T off the line going to the external and run it to the internal as well.. any input?

Re: dual wastegate using external and internal?
yes. The problem with internals is they usually don't stay shut and cause you to build boost later/not build as much as you want. But if all you're worried about is spiking, I don't see why it would hurt anything.

Re: dual wastegate using external and internal?
trying to regulate both wastegates would be the trick
they arent gonna wanna open at the same time so youll have to use a pair of boost controllers and set them independant of each other so you can match the boost between them

If your running the internal gate on such a large turbo and having spiking issues, switch to the ext. gate and rig the int. gate shut.
Keep it simple. Dont overcomplicate a simple concept.
run a 38mill

true.. i've seen a lot of high hp setups running dual 38mm ext. gates so i figured that running the internal would be a cheap solution.. i might still try it for ***** and giggles
