Default Most boost anyone has ever run on a Subaru?

Kind of a noob question...

But I'm curious to know what is the most boost anyone has ever pushed on a WRX block, STi block, and any aftermarket blocks.

I have read of someone pushing 33 on GT35R. What are usually the highest boosting turbos?

I have heard of full drag trims running well over 40psi. The block isn't the limiting factor though, its the pistons and rods, and compression ratio.

Glad I could help.

There was some dude running a variable vane turbo out of an F350 that I think had mis-adjusted the wastegate while tuning it the first time. It spiked to some crazy nuts number, and then went pop. i really should look for that thread cause I'm curious as to how that project is going.

Not a Subaru but there was a Supra on ebay several months ago running 59psi on race gas.

I remember back in the day when I never used to come to NASIOC. Now I remember why. F****** christ, I feel like I'm on VWVortex or something.

Ever hear of Crawford, Cosworth, or Axis blocks?
I guess not


To those of you that posted with a bit of thought and decency, thank you. I guess carrying out an intelligent conversation is too much for these incompetent arseholes in the Newbie forum.

...ask stupid questions---expect stupid replies(ers).....

....boost is, really, irrelevant.....it is JUST a number.....not 'power' or 'speed' or 'macho balls' or 'jizzload' or any of that.

I know that an amount of boost doesn't mean that much. I was just curious to hear what some of the 600+WHP guys are running.

When you see a POS 1.8T Jetta with stock internals and stock turbo easily running as much boost as some highly modified STis, it kid of gets you wondering. Is their stock motor going to be reliable when pushing 20+ PSI? Probably not.

Hey, you never specified a subaru-specific aftermarket block, but rather "any aftermarket block".

If you want an intelligent conversation, have a look in the technical forums - in this case the Proven Power Bragging forum where I'm almost certain there are a few threads concerning just this very topic.

If you can't take a little tongue-in-cheek, then maybe nabisco isn't the place for you... All sticks must be removed from backsides and left at the door.

....deeeeeeeeeeewwwwwwwwwwwwwwd........boost is irrelevant, really.....what IS relavant is CFM.......a td04 at 20 psi isn't moving as much air as an FP Red at 20 psi....and reliability is uaually in the toon....NOT the boost level

Race cars and street cars are NOT the same thing and WAY-WAY too many kiddie ricers THINK that just because race cars do it is MUST be good and necessary for street cars which is a HUGE fallacy.....which is where all this stupid rice comes from.....

SOOOOOOOOOOOoooooooooooooooooooooooooooooo........ this 'boost' thing ya got goin is goin in the wrong direction....ya need more learnin 'bout boost/cfm/FI

...for instance, this thread which lists off the setups alot of the really fast guys are using, this thread on PDX Tuning's 424awhp car, this thread on Kingpin's 513whp/475wtq car (reached at 30psi) and finally, this thread on the kind of setup you can realistically expect to run on the street.

If a dumbass like me can find these results (and pages more) after a minute of searching, then anyone can. Next time you want to participate in an intelligent conversation, have a look to see if that conversation is already taking place somewhere. Otherwise, get used to us having fun while your questions get answered.

To reiterate what Uncle Scotty said. He to busy being abused at work to take care of noobs. CFM is the gem you are looking for. CFM at lower boost = a cooler charge also.
See Hotrods turbo printout.
