Wastegate Sizing

Just a curiosity question. How do you go about deciding what size wastegates to use on a system? I know what they do but have no idea how they are sized.

I could never get a solid answer from anyone. Just said to copy what sizes others were using. Cause that always works so well lol. I feel as mine is under gated now.

I have never seen any type of equation as you only have a few things to go off of besides drive pressure.

What else should you consider besides drive pressures?

He guy who runs turbo smart USA advised me for the boost pressure and the size motor I have. He said to go with the hyper gate 45hp. These have a better spring system that's good for a higher psi diesel. I haven't put it on. I will when I put the nitrous kit on it.

What psi and what spring were you recommended?

I have heard a lot about the hyper gate 45. And know a few people that run them.

I found this pretty decent article. Still sounds like you just need to call the wastegate manufacturer to size it though, lol. Power Adder Tech: Properly Sizing Blowoff Valves And Wastegates - Dragzine

I told them for my set up I want to go a max of 65 or about. They Set me up with a 35psi spring. When I hook up my eboost 2 black boost controller ( their regular eboost2 only goes to 60psi they have one that goes to 120psi) that I should be able to hit my boost goal rather easy. I make 65psi with no gate right now.
