What's up guys, this may be posted in the wrong section and if so my bad. So I just installed defi bf series gauges and my boost gauge is showing me my vacuum at idle is about 17 inHg, and my boost max at wot is about 13.5 psi but tapers down to like 9 psi by redline. Do you guys think I could have a vacuum leak somewhere?
Okay thanks a lot. Also I was wondering, is it normal to hit a higher peak boost at part throttle? Mostly like passing on the highway. Sorry for the newbish questions, but this is my first turbo car
Hmm. Well it'll do it in fourth gear also. It just depends on my rpm's and throttle position. Peak at wot is about 13.5 psi while my peak at part throttle is 16 psi for a brief moment. That seems like quite a "spike." Does something seem wrong here?
Sorry for the really late reply.. but to answer you question Paul, no it doesn't seem to matter how cold it is outside (although it's easier to replicate when colder). Also the car is at normal operating temp. I try to stay out of boost as much as possible until it reaches normal temps.
Well i turned the preload screw a half turn ccw and now it'll hit about 13 psi under the same driving senarios!Thumbs Up Thanks for all of the inputs guys
