Anyone else have a boost creep issue and been able to resolve it without porting the wastegate?
Specs- Turblown IWG Borg Warner 8374 Kit, turbosmart actuator, streetport, 3 inch exhaust (Reinhard blast pipes with magnaflow muffler in midpipe)
Currently I am just running at wastegate spring pressure at 15psi and creeping up to 18-20psi.
Check your preload on the WG actuator. If you have too many turns it can cause you to boost creeps. @ what RPM does it start to creep?
I haven't had any issues with my setup.
I tried all the way until there was no preload and still nothing. On my original setup I had the opposite problem. I had the stock actuator and a the Bonez highflow cat and my car held 14psi and dropped to 10 psi by redline so I swapped the actuator and the midpipe (turned out the cat was melted) I’m not sure if I have another underlying problem since my car seems to be running hot causing the manifold, DP to glow red
Gotcha! Try switching back to the stock actuator and see what happens.
My buddy @estevan62274 had similar issues running the turbo smart actuator using a 4 port BCS and the boost creeped. He ended up switching back to the stock actuator no issues after.
What are your AFR's and timing in boost? Also @ what RPM are you creeping?
With my setup, I only saw a .5 psi creep REVVING it out to 7k. I also have 5 turns on my WG rod.
Hmm okay maybe it would be worth a try to switch back the actuator! But my AFRs are around 10.2-10.5 in boost, not sure timing. And usually in the higher RPMs I start creeping like above 6K
