YACT: Any Subaru WRX or STi owners on right now?

[SithSolo1]

If you have a factory installed boost gauge can you tell me what it reads at:

idle
cruising(3K ish RPMs)
full boost

and to your knowledge has it ever gone below zero a.k.a. negative boost?


Thx

Ok so it should never be in the negative while driving. Guess it's time for the shop.

 

[amish]

not sure, but i did stay at a holiday inn express last night.

Maybe it's going negative if you come off the throttle. The recirc Dump valve will release excess boost back into the air intake, so boost will drop completely.

I don't have a boost gauge on mine....yet.

Just cruising you shouldn't be boosting anyway. What do you mean by negative? Do you mean vaccuum? It shouldn't go into boost unless there is a decent drag on the engine/on the gas a decent amount.

 

[SithSolo1]

the boost gauge goes from -.1 to .15

The car is idling at stop lights at -.08, cruising it is sitting at -.05, but when you upshift or really mash the gas it's instantly flips up to .1 and then bounces back and forth between .1 and .07

I know in idle or cruise it shouldn't be boosting but to me that would imply it'd be right at 0 not negative thus impling a vaccuu situation.

 

[PaNsyBoy8]

your car is fine, u shouldn't be in boost, all the time, and it should be in vac when idle or ur just crusing.

 

[Platypus]

No boost gauge, sorry.
