Wastegate Battle: 38mm vs 44mm vs 60mm

[vdubkilla]

Well I've actually been discussing running 2 three port solenoids to reduce the boost pressure and was pretty certain it was possible and thought a 4 port can do the same but I have yet to delve into this aspect of my build so I'm not certain yet .I am sure in the near future I'll have a good education on the exact workings of either (2) 3 ports or one 4 port but I hope it can be done .What you say does make sense though I guess I'll just have to do a little more research on it .I will say this I've def made over 30 psi with a 3 port and a 7 lb spring in the gates

I agree with Almk, i am not certain where you read that you can reduce spring pressure but i also do not believe it is possible. Essentially you can't run a boost pressure lower than the spring pressure. A boost controller is only used to increase the total boost you want to run but adding pressure to the top of the WG. Would be beneficial if there was a way to reduce it but with the range a 4 port can operate in, just running a lower psi spring is also a reasonable option.

I think a 44mm wg is perfect for almost every application on this site. some people run twin scrolls and 2 44's might even be overkill but when it comes to preventing creep overkill is best lol. A 60mm wg unless your running some 800hp monster is unnecessary.

I didn't read it anywhere apparently I was given the wrong info or misunderstood the guy that I was discussing it with last week at Cecil .As I said this is my first time exploring with 3 and 4 ports but you can bet when I'm done I'll know it well and have it perfected .I'll be making the change to reduce the amount of boost I can run if it means changing my wg springs then that's what I'm gonna do as I'd like to lower it to a few lbs in first and second on the street so I don't have to back pedal so much .I do indeed love the twin 44 mvrs they control boost so good up top it holds rock steady and you know I'm always one for overkill lol
