Twin Tial BOV's?
 

Has anyone ran two 50mm tial BOV. ? is it even possible. ? i was just wondering.

Thanks

Pointless if you ask me. Can it be done..sure. Think about it, 1000whp cars usually run 1 50mm.

Yeah it has been done, but with the mods in your sig you really have no use for anything besides a stock IX bov.

pointless like already mentioned Evo's with 1000hp only use one so why would you want two....

The only time I've heard of people running dual Tial BOVs was on some TBs that were known for shaft breakage. Sizing the spring properly would probably have helped just as much though.

Yea i agree with everyone. i had a buddy that wanted to run twin bovs and i didnt know anything about that so i figured id post a thread.

Serious overkill. You could go with twin HKS SSQV, some Supra guys do that.

That would sound pretty good with twin hks. but how would it affect your performance

PM antilag_200

HOLY SH*T YES.lol that is NICE. were can i find one of them lol.

We run 2 BOV for 42r / 50+ psi applications like our 1000whp Evo.. {thumbup}

antilag_200 made it by hand. One of his hands is a welding gun. Freak accident - but it comes in handy.

PM him, I am sure he will be happy to talk about it.

well im out of luck. lol unless i can build a 1000 hp evo and i dont have the money for that. that is really nice setup tho.

Arent the tial BOV's setup with psi springs? correct me if im wrong but what if you get twin bov setup each with small number of psi spring like 6 psi in each. that would be just like one 12 psi. or do i have the wrong idea

EXCEPT for the fact that, thats just about the worst BOV on the face of the planet!!!

Just found this thread from Mike and your Pm.

IMO, for high boost applications/high HP cars, you do not NEED all that discharge of air. On my personal GT42 DSM I use only one valve.

my whole idea with the twin BOV was to counter "surge" if you want to call it that at all load conditions. so by using two valves, with different spring rates in each valve, I would be able to eliminate all conditions of surge/stall.

My theory comes down to placement of the valve in relation to distance from the turbo or distance from the Throttle body. Which one do you want to protect ? BOTH hopefully.

My vehicle is a little different since I use a PMAS air meter in blow through configuration. So before I DID THE twin BOV
if the spring rate was too high I would experience reverb/surge
if the spring rate was too low I would experience stall down low.

it is more of a driveability thing to me, but it really NOT required to run 2 BOVs, it is overkill.
if you are interested about reading more about how I went through the project go to this thread and read through it

I think the twin BOV theory begins around page 5 of my log.

Remember this is my solution to an issue I had with my car, it works for me, but may not work for everyone else...

Hope this helps
here is a picture of the set up in the car
