hey anyone with experience with this waste gate?

I have two of these just sitting was wondering if one would be sufficient to hold 20 psi boost on a rotary?

or modify my eBay manifold to use one for each runner?

anyone?

 

one will not be enough. if you are going to modify an ebay manifold just build one...

 

The problem with a single 38mm style gate is that you will most likely have more boost than you want, not less. The wastegate spring and the boost control plumbing affect the maximum achievable boost.

 

I'm using one on the stock turbo and motor. You will want two for anything more.
