anyhow 3 turbos that are brand new at 11psi blowing up? need more info after you check the oil return and oil line restrictor. also i would take apart the turbo to see exactly where it is failing so you can get a better idea of what is going on

I have worked on more turbo cars than I care to count, and I have seen my share of ghetto turbo setups with no BOV to, and incorrectly adjusted BOV. But whats makes that even worse is they paid good money for that nice looking BOV and it was adjusted incorrectly because the user didn't know better. I have seen with my own eyes what it does and im to smart to not run a BOV/CBV.

There's atleast 1 or 2 users in this thread that I could see frequenting my newly suggested sub-fourm haha

thats great that you have worked on SOOO many turbo cars UNISA, I don't think anyone is questioning that. what everyone is questioning is the relevancy of zero bov causing a turbo to blow prematurely. now unless you can say you have first hand experience of a brand new t28 boosting only 11psi "blowing" which the thread creator I think needs to clarify, I think that there are many more reasons that would take priority to putting on a BOV and assuming the problem solved.

I'm not trying to attack you statements, just trying to point out that you saying, "Let me take a guess in the dark your running and aftermarket BOV because it makes cool noise but you dont know how it is suppost to be adjusted." sounded like you being arrogant and assuming this guy just put on a BOV to sound cool. Not really helping em out in the first place.

Your right, but he never answered the question so all anyone can do is guess.

BUT who the hell does have experince with "blowing a 3 day old T28", now, who knows it probably was due to bad lubrication or restricted in the return line.

I ran no bov because the car was only going to be a track car. No bov on a daily would be stupid. Don't believe everything you read on the internet, use some common sense.

i not going by what is on the internet like he is...

i ran my car for couple of months w/o a bov and notice no diff in spool or power. no extra blow by... nothing... and nothing changed when i put a ssqv on it.

but since then i blew that turbo and have sold the ssqv and will prolly run w/ a bov for a while..

It's all "real" compressor surge. It's just a lot rougher on the bearings of the turbo when you surge at high massflows(on boost) vs. closing/reducing the throttle and getting some light surge.

Uhh... Ok. No point making this into a Who does/doesn't run a bov thread.

Even if he DD'd his car across country, the turbo wouldn't blow THAT quick.

i feel bad for all those poor turbines.....

200$-->

renegade_ewok · 08-25-2008, 04:25 PM

3SGTE motors in japan never ran BOVs from the factory to the best of my knowledge - my friend has one swapped into his celica and he is on stock turbo at >100k miles.

He got the swap in the 70k range I believe. Thats 70k without a BOV. I think that the hundreds of thousands of dollars in research that toyota put into the GT4 outweighs pretty much what garret has to say.
