before i took my motor apart i was getting some serious creeping issues. i had the 8.7 psi spring, set via boost controller at about 1 bar and it would creep up to 19psi boost cut.

would throwing a 11 or 13 psi spring in my tial 38 solve this so i can turn the boost controller down more, or do i just need a larger wg? help me figure this out before i build my new motor. thanks

I have creep issues too and I was told to try to hold 15psi to use a smaller spring such as a 4 or 5 psi spring, and raise the pressure from there with your boost controller to what I want it to be. Depending on your turbo/manifold the Tial 38mm probably is just too small for your needs.

t3 60-1, miniram manifold. kinda wondering if i should get a whole new manifold, or just weld a 44mm onto this one in place of the 38. just looking for other options before i do something like that

springs wont help get the larger gate and/or a new manifold. i tried higher and lower ones, they end result was always the same sooner or later they hit the same boost level at higher rpms

thanks mike, that was the advice i was looking for

im having the same problem too... except im running the mini-me manifold w/gt3076 and a 44mm wastegate. I would think the 44mm wastegate would be able to handle a gt30 on that manifold.

ya it should be able to handle it... i'm running a mini ram, and 44mm gate, with SC61..... 9lb spring, no boost creep

hey guys, i dunno if this has much to do with it, but the creep really only became pronounced and real noticeble once i started using drag radials on the street. i think before it would still not have 100% traction and the motor didnt have a much load to make as much boost

jeez, i wonder if its the wastegate placement on the manifold?

Yeah thats what im thinking... I might add another wastegate onto that manifold but i'm just really shocked that the manifold is creeping with a gt30. I use to have a t3/t67 on that manifold and it held 10 psi no problem. But then again the old turbo was a .63 on the exhaust side compared to a .82 on the exhaust side on the gt3076. I assume that would cause the boost creep.
