dual DSM BOV on a high boost setup?
 

sup nigs? I plan on boosting ~ 20 psi w/ a T3/T04E 57 trim 63/60 in the new few weeks, and I've been thinking about a BOV setup since that's the only thing i'm missing along with charge pipes.. instead of spending a good bit on a tial bov that is capable of releasing high amounts of air quickly, why not run 2x DSM BOV? has anyone tried this before?

why stop there, try running 4.

i'm pretty sure if you ran a dsm blow off at 20 psi it would leak, thats why people crush them so they can handle more boost.

I believe 2 bov would still see 20+ psi....Not sure it would be divided by 2 if that is what you are getting at. Imagine if you are underwater and there is 1000psi on the submarine...If you have a hatch that is rated at 500psi, it will blow, if you have 2, it will still fail..you need one that is 1000psi..right??? yea I am pretty sure I am right... :y

I have two DSM BOV's because I'm planning on doing this and while it holds 20psi+ it also makes them open slower. Anyway it seems simple enough, and I'm willing to try whenever I get a turbo capable of high boost.

That does make sense, never thought about that...I guess it would vent twice the amount of air to help avoid compressor surge, ect. btw, good site^^^^lots of good usable info that is applies to many configurations.

Just crush the DSM BOVs and run 2 of them. If you crush them thy will hold more boost. If you run two they will evacuate a lot more air. Plus two DSM BOV's are cheaper than 1 Tial or something.

I can tell you that 2 DSMs, one on each side of the intercooler under the headlights with the outlets pointing forward (away from tire sludge) sounds tits.

that wold be kinda cool

Re: dual DSM BOV on a high boost setup?
 

thats why they crushem :S
nice
never ran one uncrushed and always wondered why

Re: dual DSM BOV on a high boost setup?
 

ud be fine with one crushed DSM BOV

Re: dual DSM BOV on a high boost setup?
 

word on the street is jd's setup will be hosting dual bov's.

Re: dual DSM BOV on a high boost setup?
 

Don't forget about the garage mod you can do to the 1G BOV to allow it to hold higher boost levels. There's a nice write up floating around the internet. Just search 1G garage mod. I think 2 of them modified for high boost would do the trick and then some and still cost about 1/4 of a Tial.

On my old rx7 I had one of the dsm bov's with the bottom bleed hole JB welded and it held 30# no problem.

Re: dual DSM BOV on a high boost setup?
 

I've never heard of doing that, did it open a bit slower?

Re: dual DSM BOV on a high boost setup?
 

what the advantge of haveing a bov by the intercooler?is it just to hide/make room for the bov?

Re: dual DSM BOV on a high boost setup?
 

I place mine before the intercooler so it is not charge cooling air that would otherwise be potenially wasted. It also heats up unessesarily when you could have just bypassed the air instead of making the intercooler work that much harder.

Re: dual DSM BOV on a high boost setup?
 

It is the same thing as doing the above link

just without the option of hooking a vac line to the underside port.

It still opens up fast, just blows of harder. Don't think I would do it for anything under 15#, but I never had that car under 30 so it worked perfect. :)

Re: dual DSM BOV on a high boost setup?
 

By putting the BOV near the intercooler and not the throttle body, air that is between the throttlebody and the intercooler, will have to reverse directions in the piping to be evacuated by the BOV. This will create more lag as the airflow isn't as smooth.

Re: dual DSM BOV on a high boost setup?
 

Some say put it right after the turbo, some say put it on the pipe going to the TB, so I did both. I need to do the mod sometime, but I'm lazy.

I linked it above.

but wont 2 BOV be Cool? make a Unique sound when dumping?

Re: dual DSM BOV on a high boost setup?
 

And the splog. :6
Speaking of JD I need him to find me some ---- I need soon.

Re: dual DSM BOV on a high boost setup?
 

Yeah it does sound different. My drivers side bov sounds different than the passenger side, it even opens first (I guess because the vacuum line is shorter) so you get a neat effect.
