Running a Turbo with no pressure on it???
 

I have a quick question. If I run my car with the turbo bolted up but not conected(Basically not connecting my charge pipes). Is that in some way harming my turbo because its spinning with no pressure . The reason I want to know is when I get my new turbo for Westcoast Turbos in, I want to run my car a while without boost until I can get it to a dyno and have it tuned. Plus I just put my head back on and I kind of want to make sure everything cool before boosting again.

It will eventually ---- your turbo up by over-spinning. That fucker will spin balls out forever if the pipes aren't hooked up. If you *had to* do it I would make sure the WG is all the way open.

yea and make sure you hook up the oil lines....

Re: Running a Turbo with no pressure on it???
 

So your saying that I should make sure that the wg is hooked up. My wg is set a 8.5psi how would i make it stay open.

Re: Running a Turbo with no pressure on it???
 

take off the wg arm n make the flapper stay open... do not connect the wg in any way. basically take it off so the turbo can't ever over spool. but it will still possibly mess up with no pressure. why dont you just hook everything up n just dont boost? its easy to stay out of boost. even going up hills im just at 0... part-throttle is your friend.

Try that with a T25. :P

i had a t25 for 6 months... n i only upgraded to a gt28 which aint THAT much bigger... :P

indeed, you can really overspool the turbo by driving it without the charge pipes hooked up. Like mentioned you would have to completely dissconnect the wastegate in order for it to be safe to drive.

Re: Running a Turbo with no pressure on it???
 

yeah just disconnect the wastegate. Thats what I'm doing right now cause I doing one thing worse than you, I'm running a turbo without the oil lines hooked up :-X

Well I would hook up the oil lines if there was an oil pump on the motor ;)

Re: Running a Turbo with no pressure on it???
 

carb spring method?? very loosly done.. should make it run like 3-4psi.. which isnt ---- really.. so.. i think thats his best bet.. or connecting the pipes and purposely having a leak... soemwhere in the setup.. to bleed off most of the boost..

Re: Running a Turbo with no pressure on it???
 

Ummmm.....is it going to build 3-4 psi into the atmosphere? That must be one hell of a turbo. :S

definitely wouldn't work, you'll still be overspooling the ---- out of it. unhooking the wastegate would be the best way to go

Re: Running a Turbo with no pressure on it???
 

If you drive very easy/low rpm, you can get away with it. Just try not to punch it and get the charge pipes hooked up asap. Also just in case you didn't know, by no means even turn the car on without oil to the turbo. It's also a good idea to prime the oil line into a bottle/container so you can get any dirt/shavings out of the line - it only takes a small amount of contaminants in the oil to tick those bearings off and have you smoking down the road.

Re: Running a Turbo with no pressure on it???
 

Just connect your piping up, its really pretty easy to stay out of boost if you're not retarded. I drove two weeks with a full turbo setup without engine management. I never went into boost at all-- its pretty much all on throttle position-- you can wind out to high rpms without ever coming near boost if you don't go high throttle, but if you floor it at low rpms you will hit boost or raise up enough that the map sensor will throw a code. Just drive conservatively with your charge pipes hooked up and you will be fine
