Hooking up the waste gate to a vacuum source

Rocknit4x4 · Jul 9, 2024

Hey All
So today was my first day driving my truck with a turbo kit installed. 92 F250, CDD stage 2 kit, R&D factory NA pump turned up 4 flats, R&D injectors. On flat roads unloaded I got up to 9-10 PSI. I’m totally happy with that but was reading about others who mechanically bound the waste gate to prevent it from opening and this thought process led to this thought:

In lieu of mechanically binding the waste gate, has anyone tried hooking the reference line up to the vacuum distribution block or direct to the pump? If so, what were the results?

I havent tried that, but something I did with good results was use a worm gear hose clamp that goes around the wastegate arm and the diaphragm bracket. Has to be like a 5" diameter clamp to work. Definitely helped my boost issues until I installed a wastegate delete flange

I’m sure the vacuum thing would work.

Using a piece of all thread or a long screw works too. Here’s mine

On my factory 093 I just drilled the spot weld off the wastegate actuator arm and can now thread it to whatever I want. How is your tailpipe smoke at 4 flats and 9-10 psi? EGT's?
