Default can you drive an STS car untuned?

just like the title says, i'm going to pick up my car today and i just had my sts kit installed. i need to fix the exhaust, so if i drove it like 30 miles to and from the exhaust shop and back to my house, would everything be ok? i dont mean like driving the **** out of it, i mean like keeping it under 3k and just cruisin. its gonna be like a week before i get a tune... but until then, would everything be fine?

and one more thing.... my tranny is stock with a tranny cooler, so how long is it gonna last with the sts as long as i keep my street tires? thanks for the info!

As long as you stay out of WOT you should be fine.

as long as you don't even remotely reach any signs of boost, you should be able to drive it a short distance, not sure if 30 miles is okay. But your tranny would be something that could say bye bye as soon as you get into some boost and start driving it like you should

I was seeing 3 psi at only half-throttle on mine, so watch for that.

i am gonna have to agree with the last guy...but again if you HAVE to.....you should not go over like 10% throttle and 2500rpm...you are gonna have to drive like a moron to avoid any sign of boost and you still might do something bad to the motor. i would say avoid it

It will be all in the THROTTLE. Personally, I'd screw it up going that far, just using the gas pedal like you might be used to... Those are alot of miles to chance a mistake on.

i disagree , as long as your stock injectors are in and dont go into boost nothing will happen to the motor. i had to drive 45 miles to get my tune. i kept stock injectors in and drove carefully not ever going into boost. when i got to the tune shop i swapped in my 42 lb injectors and tuned the car. . you wont be able to have jack rabbit starts but you can drive away from stops just as fast as other normal driving people, i drove on the hwy at 75 mph with no ill effects. watch your boost guage and dont let it get into boost period....

i still have my stock injectors in, but i have 60's for when it gets tuned... i did just put a cam in, but before the turbo, it ran fine. i just need to fix the exhaust because it hangs too low..... plus i need to get rid of the cats

do not do it. chances are u will see boost even if ur careful not to go in it. if you load up the car in like overdrive ur done. u wont even know it, but you will be detenating like crazy, and the start to your engine failure will have begun.

so unless you got another 3k+ laying around, do NOT mess around with this

Unless your running a HUGE turbo, chances are you will run into positive manifold pressure at anything over 10% throttle.

on my car i can afford to give it 30-40 percent without worrying about getting into boost, but thats cause I have a big *** ******* turbo

Default don't do it

I was in the same boat, I figured I would just drive mine with stock injectors to the dyno taking it slow. I ended up paying 90 bucks for an enclosed trailer insurance included from taylor rentals. Now that I look back at it, it was a no brainer...not worth the risk. If you know somebody with a truck definitly trailer it. Unless you can leave the charge pipe off and run stock injectors untill you get there then just put the parts on.

that is an other idea...if its an sts kit you can dissconnect one of the pipes and drive there basically without the turbo hooked up....make sure you take a pipe b4 the maf off....and right up a filter if you can....or at least something to keep the big stuff off. I know its kinda ghetto but if your not willing to pay to not drive it then thats prob you best bet.

with a front mount turbo like 2000 tran Zam it spools alot faster, on an STS it takes much more to spool the turbo, i have a gt67 and when i drove to the tune shop under normal driving conditions you will not go into boost. even now with a tune and wrapped exhaust i wont go into boost unless i load up the turbo and get above say 2500 rpm. you do what you feel is best for you, trailer would be the best but not everyone has a trailer. if you must drive it just take your time keep you eye on the boost guage when taking off and drive normal.

navymitch do you go into boost all the time daily driving???

Wait, why dont you just remove the spring from teh wastegate and let all that pressure bypass out?

Will be easier probably then disconnecting the turbo...

Just remove the wastegate entirely. I tried this just to see what would happen.

Default taht would work!

just disconnect the front pipe and run the stock air cleaner setup till

yah get there. its not hard to switch back or time consuming at all.

i would go that route before taking chances

for some reason my car didnt like the sts kit at first

and it really didint want to idle correctly or run part throttle

dont take the chance on your car stalling and it dying

out on the highway

YOULL BE SCREAMIN

NO BRAKES!

when i do it im just going to take out my wastegate spring, even though ive heard they are a bitch to re install......

If i keep a close eye on my wideband, as long as it doesnt go anywhere from 9.0 to 12. i should be fine right? if im drving and its at 10.5 could it be denonatng without me knowing it?
