I installed my turbo wednesday and just fixed my dp and crap today. the car pulls really hard at 10psi and runs great. I installed a btm last night and now I am noticing my boost is hitting 15 psi!! I am running the wastegate (deltagate) and btm off the brake booster and boost gauge and bov of the fpr. I am running an safc and new btm and 440 DSM's. I have a .50 trim T3 (brand new) , custom manifold (wastegate port mounted right on top of the "log" ) custom 2.5" charge pipes and no intercooler yet. 2.5" dp and bosch bov. Am I safe boosting to 15psi? somehow I doubt it so what should I do?

also, what setup should I have engine wise to run 15psi daily ?

EDIT: I am not throwing any codes when hitting 15psi!

I am guessing that you are getting boost spikes off of that delta gate. Is the motor stock?

What kind of spring does the deltagate have. I know I have one that is adjustable from 9 to 15psi.

legendboy

My motor is stock, fresh rebuild. I have the 9-12 lb spring in my deltagate.

rjardy

Delta gates are adjustble if i am correct, so try turning it down.

How can you tell what kind of spring you have in the deltagate and how do you adjust it? I am hearing two things, tighten it and you have more boost and also, tighten it and you have less boost!!! Which is true

legendboy

take the spring out and look what color it is. the black spring is 9-12 and the green is 3-6 or something like that. tighting will increase boost.

oh, I installed a new T from the local parts store for my BTM. It was one of thoes T's that have the 3 levels of diameter on each leg. I didn't cut off the smaller openings and make the hole bigger for my bigger wastegate hose so the wastegate was basically runnning unlimited boost cause it wasn't getting enough pressure through to actuate it. I cut the small tips off and vola! 10psi

next step for you 1:intercooler, 2:ditch the deltagate for a tial, or say peace out to the rings

I'm one of thoes people who think deltagates are ok. Just hook them up right.
