Open Turbo good or bad?

ok ive heard a few ppl say good n bad things bout open turbo…my buddy ran his turbod gsr open turbo for like a month or more and it didnt hurt squat. but i ran mine open turbo for like 2 wks and just 2 days ago like it makes a wierd noise at full boost(6psi) and feels like its holdin back on power. it has a lil ticking noise behind the open turbo racket…and it sounds fine at an idle…just makes noise at partal throt thru w.o.t but like i said it just happen like 2 days ago…any ideas??:wtf:

What do you mean by open turbo?
No air filter or no exhaust?

o my bad lol…no exhaust

I don’t see any problems with that personally.
Long as it’s routed away from anything.

yea it is…but the reason y i was askin was cuz my car startin actin wack 2 days ago…n didnt kno if that might of screwed sumtin up

What is the car doing?

what? so you have nothing bolted to the exhaust side of the turbo? there should not be anything wrong with that but you are dumping all of the exhuast gasses in your engine bay? im going to assume you have at least some kind of piping to get the exhaust out of the engine bay. There will be a decrease in power if you have the intake sucking in all those exhaust gasses. Thats why they make dump tubes. They actually make hp when the wastegate is open. You don’t want that lack of oxygen in your engine bay where the intake is.

look up n read my lil info

lol yea i dont have nothing there so yea the fumes n shit r runnin free. but like i said it was runnin fine like that for like 2 wks and 2 days ago it just started actin up

i would get at least some piping and get that exhaust out of the engine bay. You are not allowing oxygen/clean air to get to your engine.

sometimes u can get them over boosting because an exhaust system helps with mufflers cats etc. with back pressure but removing the exhaust or even havine a straight through system removes all backpressure and therefore can over boost even with a gate present…

for example i changed my old supras dump pipes to better flowing ones and (this was without a boost ctrler and stock everything else) i gained 6psi boost i went from 10 to 16 or when cold (with no cat like what ur talking about) sometimes to 20psi

having said that my turbos (being shitty ct12as ) didnt last very long

so its a possibilty that i couldve f’ed up my turbo lol…not sure how turbos act when they blow seals…but yea. funny thing is there is no play n the turbo n it spools alright but it sounds like i have a bad exhaust leak…which i kinda do considerin no downpipe on the exhaust side of the turbo…

it just gives blue smoke… or sometimes white depending on how the turbo is made but most the time blue because i dont think ive seen a water cooled turbo break in the way u would get white… but sometimes it can look white

its possible u overspun the turbo yes.

well shit this sucks lol…i swap out turbos n c wat that does…thanx for the help

i still dont understand y u wouldnt run a dump pipe or anything still… i understand minimal restriction but if u put a dump out the side the car and that way u evacuate the exhaust away from the engine bay and get cleaner air to ur intake but thats just me
