Blow off valve

Hi just bought a 2006 evo mr and wondering what kind of blow off valve is best for my car? Dont plan on upgrading the turbo so I need one that isnt in excess of over the hp of the evo presently.... Ive seen some 500 hp and higher rated blow off valves but dont think I need that .... Just want a opinion on what is the best cause i rather spend more for something that is good then get screwed in the end :-) thanks

ok well BOV arnt nessesaryily measureding HP as it is boost PSI, a 500hp rated BOV could only need to hold 20PSI on some cars where as others may need 30+PSI. I would say the Turbo XS type H I belive or the Greddy Type S would be best for you since they are easily plumbed back into the intake as needed. other wise you can get the JDM MR DV which is just as good and is a cheap option. your car should be running around 20\21 PSI stock so they should be more than enough to not leak under load

I heard that the HKS sequential was alright. I have an 05 EVo and I just ordered one. It's the whole kit so there's no cutting I'm told. I'll let you know how it turned out in about a week. Question, The EVO runs 20lbs of boost stock??

yes the 05s run 20.5 stock the 03/04s run 19 and drop tp 16 at about 4500RPMs

as far as the SSQ if you dont get the recirc kit for it the car wont run 100%. it will have a bouning idle and you will get more turbo lag after shifts. and between gears if you let the cars RPMs drop all the way down it will stumble and nearly stall out

i'll go turbo x's....

Tail is a popular one... but everyone gets the JDM MR DV since its cheap and not plastic like stock it holds a good amount of boost, so no need to spend a fortune on a BOV ya know

turboxs h with the recurliate kit works great on the eclipses. Couldnt be happier with mine.

for the money on the EVO the way to go would be the JDM MR DV

greedy type s or type rs is good also but more $$

here r some pics of good bov
Turbo XS Racing Bypass Valve Type-H34 $149.99

Forge Motorsport Type RS Valve - Recirculating $219.00
bov for 06 click link for bov page

the JDM MR DV is like half as much as those and holds the same max PSI that is why I stand behind it. Im all about saveing money and getting good modds

im using a hks dump valve , and im running 350 bhp , in a 2001 evo 7 ..
and ive had no problems what so ever , .... hope this helps..

are the the blowoff valves the same,as far for being loud?and whats a loud one?

you dont want a loud one. If you vent it you will make any BOV loud but it will make your car runn horrible so recirclateing is a good odea and that means it isnt as loud but with an intake it is very noticeable still. just search the BOV thing we have a few LONG disscussions about venting Versus recirculating and explaing what it means and why one is good and the other isnot

Plus if u want to go Vented u have to buy a this little regulator that makes sure u don't stall when ur ideling, so yeah it's definatly a good idea to get the recirulating kit cuase it's less headache.

can you hear any of the BOV w/o going vented thats all i really want.a year or so i would like turbo upgrade,as for now i just want to hear that BOV sound if i have to il get the venting setup i dont want the headache.what BOV should i go wiht/what are you guys working with?

I am still on my stock BOV if you get an intake you can hear it just fine. people can hear it from a distance away still. I strongly recomend not to vent your BOV cause the car will still and run like ass and it will be slower and have more turbo lag.

The popular EVO BOVs are Greddy Type s or JDM MR DV they both hold boost well and sound better than stock. Just buy an intake and you will hear your BOV and youll be happy. I know my stock intake you could barley hear it at all and after the new intake went on I was surprised it was alot louder and the turbo spooled and sounded alot louder

with a vented BOV your car will run bad. at idle the RPMs bounce up and down. the turbo lags more after shifts it stumbles when you stop and nearly stalls sometimes it might stall, you cant go 1\4 - 3\4 throttle only all or nothing because inbetween the car bill buck up and down

No you need the BOV but if you vent the BOV to the atmosphere you will run bad. the BOV releases air on our cars that has been counted so it releases it back into the intake before the turbo so that wa the motor still gets that air since it was already accounted for. If you vent you BOV it releases the air out into the atmosphere (not into the intake) and because you are not sending that air back into the intake and it has been counted for the motor gets extra fuel and not enough air which causes it to stumble.

That is why why you add and intake to the car the BOV gets alot louder since the BOV is rleasing into the intake. I Hope you can make sence of that

who has a BOV thats loud and vents back to the intake??

if you have an aftermarket intake it will be alot louder than it is with the stock airbox...even the stock BOV is pretty loud. But everyone likes for aftermarket the Greddy Type S and the JDM MR DV (which is a stock BOV on the JDM MR)

THANX, i'll get the intake 1st and see how that sounds. ok 1 more Emonz,would you say the Greddy is as loud as the BLITZ ???
