Crushed MR BOV
I know someone that daily drives on a 20g with studs,cams,meth, the bolt ons and has a greddy boost controller. He daily drives his car in wastegate and when needed hits hi boost and runs 30 pound spike then tapering off and makes good power with no problems. His car has been like that for over a year now with no problems. Just like one member said high boost does not destroy motors, turning up the boost without having it tuned does.

What's up with those comments, Turbotoyzz? I've tried to help you from day one and am still trying to do so. You don't have to listen, but I'm only trying to help. Right now, your eyes are glazed over with visions of grandeur instead of remaining grounded in reality.
Turbo you are just gonna have to understand that Wartallon is a dick writer, and thats just how it is. He thinks because he is "Sponsored by evom vendors" he can talk to the community like we are retards. Turbo if you were on here every single day, and have already read every problem you would know all the answers too. Your best bet is to take in everyones advice even Wartallons and then make your own decision. Some members will speak out of their ***, and some will speak from true knowledge and wisdom. Its your job to pick and choose the best and then decide while not listening to the people in here as a popularity contest.
A 20g is also built to run more boost than stock, and I haven't said anything about blowing a motor. It's just a bit presumptuous and irrational to get an Evo IX, read a bogus thread, then think it's normal (and wise) to run that much boost on the stock turbo all the time without doing a little more research.

Life doesn't revole around drag racing and ET's + MPH. Some people can't drive, or have a hard time driving (shifting the evo trans).
If a car is tuned properely what is stoping one from running high boost. It tappers down and lets the turbo perform efficiently.
If I make 400whp or 1765whp , I don't care. As long as I am happy and modified my car. I mod everything, sneakers , cars you name it. If the car runs 110mph, I know that there are people who will second that. Some wont but, who cares?
Not trying to be an *******, but you need to either soften up, or not reply to people. I asked a simple BOV question. That's all.
what's with you guys bashing warr right now? he's telling you all of the problems that can occur and most likely will with running that much boost. i don't see how he is being a d_ck writer right now. why do you even want to run that much boost in the first place on a stock turbo? it's most likely going to end up blowing, you're going to have to rebuild a lot of things, spend more money than needed, and not be able to drive your evo all the while waiting to install a new turbo. you can just buy a new turbo with all of the necesary mods and run that boost reliably with higher power gains. your mod path really seems senseless to me. but good luck...
Does anyone run a crushed MR BOV? And what kind of boost numbers can it hold? I know a regular MR BOV can hold up to ~26psi, Any input?
Looking to run about 34psi (spike) What are you guys doing for that kinda boost, and what drivability issues are you experiencing?
Thanks!

The stock MR BOV was never designed for that much boost. The trick of crushing them is a double edge weapon, it could hold more boost when crushed but it could also permanently leak if crushed too much, so it is your choice.
Running at 34psi you might consider some adjustable BOV or runing a tial waste gate to complement your goals. Also I want to piggyback to one of the true comments that Warrtalon mentioned, it is proven that perhaps the stock turbo wouldn't make power above 28psi.
I once ordered my tuenr to go nuts with the maximum boost and extreme tuning and we found out that going from 26 to 28psi yielded only 3whp but lost torque. Anything above 28psi on my car was loosing power and dramatically shortening the lifespan of my mechanical components.. cough, did I said I also had absolutely all the bolt on supporting mods?
It is your choice but I highly recommend other alternatives like a slightly bigger turbo and injectors that would provide you a much healthier flow of air without sacrificing reliability and performance.

Uhm, he has his way of bashing everyone. Welcome to EVOm. I want to run high boost. Why do you modify you car if your complaining about breaking things. Sell your car , and buy an Automatic Solara. Then dye your hair blonde.
Also, I'm pretty sure I answered both your questions about the BOVs - both the crushed MR bov question and the recommended BOV question.
I know the Tial is awesome, but i have tried a VTA valve in the past, and it definatly made my car run noticiable sh!tty; not to mention the CEL that stayed on constantly.
I think a crushed IX valve is a very realistic solution for me to not waste more money on pointless BOV's that dont work, but i think i might have to go the Evo15 path... Though i have heard good things about the APS duel valve as well; just not sure if it will hold 30+ psi.
Warr is actually one of the most helpfull or trustworthy members of this site. He is a little dry and harsh with his answers but still knowlegeably answers. He sure has no patience for bs and lack of research but is a great asset the community at least respect that. The reason anyone would want to blow 32 lbs of hot air into their engine is beyond my understanding because it is way past the turbo effective flow range. Coming from a couple of Dsm before the evo I know that properly crushing the bov helps it hold more boost but also turns it into trash if not done properly or overcrushed.

Or to be even easier said, stop jumping on the bandwagon. You want to follow , vote for Hillary.
Turbo is just sayin a spike not holding it to red because it will never happen. All I am trying to say is people need to lighten up on the way they answer questions. If you ARE responding to a "noob" remember that he or she is in fact just that a "noob" and does not know! They came here to the forum to ask and look for the answers he or she needs. Guys lets stop being a**holes when answering questions and have more patience. Responding in the wrong manner only turns people away from the forum and to trading their car in and making a really bad decision like..buying an sti!!
