So on hahn's website when it says internal wastegate 8-10psi. Can I tighten the actuator arm to get it to 10psi? Right now max boost is 8psi.
I don't think you will gain anything from that. Best thing to do would be get a manual boost controller, or if your looking for super cheap you can make a "leak" in the line from the wastegate to the compressor, with a t fitting for vacuum lines.
Built and boosted 2.2 ohv
Yeah I don't know what I was thinking when i posted that. I've looked into it more now. I can't decide on an adjustable internal wastegate (like a turbosmart universal one where you can change springs). Or a manual boost controller. I know with an Mbc I can only get maybe double of what the spring is in there right now. But I don't know which is better, mbc or adjustable iwg.
