If you want noise from a BOV, don't change your stock diverter valve out, just get an intake. You'll here it, trust me.

 

make sure to dump the clutch at 6k to, for the best launch!

 

He speaks the truth, although I would wait to get an intake when you have more mods and cash for a tune.

 

It will surge.....not could, or might.......it will.

If you dont believe anyone try it (it wont hurt anything - short term), and I guarantee you wont blow a coupler off but you will hear the compressor surge, mine does it stock on low boost

 

What is this "again" stuff? I wasn't saying the car will not crank up and run without these mods. I'm saying the car would not work properly. This is quite obvious - not sure why you're trying to refute me on something so simple.

Plus, you try to say I'm wrong then go on to say that the car will have uncontrollable boost spikes and the turbo will die from the surge! What the hell do you call that? I call that "not running." Good Lord...some people...

 

the diverter valve was developted for supercharged cars at first. these were designed to release pressure into the intake system to prevent compressor surge and engine wear. so u can run without, but not well.

 

So there are no turbo cars without a BOV or DV?

Ever look under the hood of a Grand National? Thunderbird turbo coupe?

My guess is not since they do not have any BOV. WHen I am in boost and let off guess what happens? Compressor surge! And it does not leak out of the couplings either.

 

Poor guy... He got scared off...

 

God. Forum people take comments so literally. I was initially joking when I said cars can run without a WG. Which they can, but it'll just be really bad.

 

woops..double post.

 

GOOD LORD SOME PEOPLE. OMG it was a joke! ARGHHGG im gonna pull out my hair at work. Maybe I need to use more emoticons.

 

Without a wastegate you will have nothing but boost, there would be no way for the exhaust gas the bypass the turbine.

Now if you leave the wastegate in place and remove the actuator that would be another story cause some portion of the exhaust gas would always bypass the turbine (most likely most of it)

To the op, the folks giving you advice may have good intentions, but the obviously have poor information. you don't need to replace the wg actuator or the bov. Your money would be better spent on an exhaust, drop in filter, and a retune. A manual boost controller and a retune. Best bet is full exhaust, mbc, retune. If money is tight, mbc, testpipe, catback, retune. If money is even tighter, mbc, catback, retune............

If you just want the vent to atmosphere blow off valve sound... well then you are just a silly little ricer VTA is not the best bet on these cars, you can do it right but that would require converting to a blow through maf setup or speed density.

 

Exactly

A guy I knew had a low cost turbo kit he bought for his civic it had a t-20 turbo and it didnt have a bov, he just let it surge...and this was an off the shelf kit. Never blew a coupling

It wont kill a turbo right away anyway but long term it wont last as long as one that doesnt have constant surging....

 

If that is the path of least resistance than you are right. I said my guess is you would blow a coupler before surging all that compressed air back through the turbo but I didnt say it was a fact.

 

When did I ever say anything about any turbo cars and bovs/dvs??? The post you quoted me saying was related to wastegates which has nothing to do with bovs/dvs. To answer your question I am familiar with Grand Nationals/GNXs a bit and I know there are many race cars, Supras for example, that dont run BOVs and let the turbo surge. Warrtalon was the one on page one that said you need a bov for the car to run, quote him.
