I couldn't help it, I just had to share this..

Ok, so with an understanding of how turbos work, I am wondering:

I have a 05' Sti...

I have the car in neutral, clutch out, and I rev the engine, the boost on the little gauge reads -.5 bar(or maybe it's -.05, i forget...it's negative anyway.) , and it won't go past that no matter how much i press the gas.

Same situation if i have the car in gear but that the clutch all the way pushed in...

And when i am driving, car in gear and putting down the road, if i have my foot on the gas steady, but not accelerating, the turbo drops back to -.05.

So if i want to roll ona nd get going again, i hav eto wait for the turbo to spool up and then i get my boost back.

So when theengine is going, there is exhaust being created, so why is my turbo not always spooling? I understand there may not be enough exhaust pressure to turn the turbine, but at 5000 RPM i would think there would be plenty of exhaust pressure.

Is there some kind of factory clutch thing on the turbo that tells it to only spool when i am pressing on the gas enough to accelerate?

I also understand that starting out at a stop and having the boost at max then tearing off the line could hurt the drive train, but i am sure the drive train can take more than 0 boost at the launch, right?

Whats going on here? is there some simple tweaks i can do to get some more performance out of the turbo by eliminating some of these odd limiters?

LOL someone needs to put this guy in the passenger seat and then beat the car within an inch of its life

Thats a pretty good one. I should unleash some of the rampant retardation that runs through the BMW community...

That's actually tame compared to some of the shit I have heard at the lot.

I'd like to try to dig up the one where Cossey tells this kid with an automatic Impreza RS to put it in "R" for race mode

We're both staring at this thead here at work and wondering how someone could possibly...

ugh. learn some fucking science before you mod a car.
