Wastegate Modification

[GTScotT]

Man that would work well on evo's lol. Their actuator sits in quite the position.

Any ideas where to buy random springs? lol, cant wait to toy with some actuators now!

is that whats goin on here?

is the bov also blocked off for maaad fludderz?

No heat issues here, and my turbo used to get very hot, no sheilding. The spring should lose tension and lower boost if there is a problem, there's 6 or more stageas running this setup with no complaints yet.

This thread has me thinking. Here is my story hope someone can help. I installed a hypergear atr43 SS-1 and after putting the smaller actuator on it runs about 6-7psi as it should until it gets high in the revs(above 4000) and rockets it's way to boost cut. Is my wastegate too small? Is my actuator wrong? Any input appreciated

The wastegate hole is too small, to open it up much more than stock you will need to put a larger flap on it. The upside, it should make more power then. The downside, with a larger hole there is more area for manifold pressure to be pushing the flap open, so you may need a stiffer spring/actuator.

Il just stick with babying it until I find someone to install a nistune and tune it. Thanks

Correct me if I'm wrong, but wouldnt heat (over time) work harden the metal therefore increasing spring tension? Or do you figure the fact its constantly made to move (while heated) it would more likely fatigue and soften the metal?

Actually HG's wastegate controller is now built into the housing.. It has an alen key adjustment that reduces flapper surface area to make them hold more boost up top. You will need to speak to Stao about adjusting this OR you can leave it alone until you put a tap on it and turn the boost up.. Which is what I would do.. Stop thrashing a car thats not tuned lol

Lol I've talked to stao and decided what I'm doing. I only have a problem when I want to overtake and forget I can't drop to 3rd.
