Dumb Question But I Need Help
 

Hey i have an 2003 evo 8 and i have a greddy blow off valve install on my car. Turnin it to the hard does what and turnin it to the left does what. Sorry stupid question but i jus wanna know. and rite now, its makin a flutter sound. is it supposed to sound like that, and is it bad for my turbo. Because ive heard serveral greddy blowoff valve that doesnt sound like that. Its a greddy type rs blowoff valve.

As long as you still have that little pipe connected, your fine : )

All it does is depress the spring a little more (harder) and when you loosen it, it makes the spring looser (softer). Harder will make the sound crisper, but too hard wont let the air out efficiently enough. Too soft and it might not hold all the boost properly. Most likely its fine where it is.

wow thanks alot man. so that pigeon flutter sound is what the greddy rs bov suppose to make rite? its not makin what they called compressor surge rite.

RE: Dumb Question But I Need Help
 

Thats exactly what its supposed to sound like.

Do you still have that pipe connected?

RE: Dumb Question But I Need Help
 

you're talkin about the little pipe thats supposed to connect with the blowoff valve rite. if thats it then yes it is. why what happens if its not connected

RE: Dumb Question But I Need Help
 

Your car will just run like **** : )

Yeah im talkin about the one that runs back to the intake.

RE: Dumb Question But I Need Help
 

Yeah its connected back into the intake. thanks alot for everythin man. hey but i do notice one thing though. after i installed the greddy rs valve, im hittin alot higher boost than i do in the stock bov. is that what its suppose to do. and everytime when i switch gears, it seems my rpm would drop down alot faster. turbo lag i think thats what its called. im sure i have it recirculated and its installed rite.

RE: Dumb Question But I Need Help
 

Dont worry about anything man. How do you know your boost levels are higher?

RE: Dumb Question But I Need Help
 

well its not higher but i think im pickin up boost faster than when i had my stock bov on. i have a boost gauge on. i think its jus what im feelin then if the bov has nothin to do with that.

RE: Dumb Question But I Need Help
 

Eh, i think you have been smoking a little too much of the fresh green : )

RE: Dumb Question But I Need Help
 

hahaha. yeah i think so also but yeah thanks alot man. u helped me out alot.

RE: Dumb Question But I Need Help
 

actually sebba you have to remember the stock evo BOV is very similiar to the 2g BOV. It is a POS. They are plastic and leak boost like crazy. Stock boost of an evo is around 18psi. But mikes would spike 18 and then it would drop to 15psi. They are horrible. So putting a new BOV on an evo is usually one of the first things people will do to be able to hold that boost. So yes its normal to feel the car alittle faster with the new BOV.

RE: Dumb Question But I Need Help
 

Yeah but boosting more and picking up boost faster?

RE: Dumb Question But I Need Help
 

well if the old BOV was leaking then i guess it would feel alot faster

RE: Dumb Question But I Need Help
 

hey yeah. the engineer, thats what im feelin. its the fact the new bov is holdin the boost where its at instead of going back down. i remember when i was drivin with the stock bov, when i reach a certain boost level, the stock bov wouldnt hold it there, it would drop back down. and on the greddy bov, it seems like it would hold the boost level better than the stock bov. i think thats the only reason why i feel a little more power to the car. sorry guys for such a dumb question.

RE: Dumb Question But I Need Help
 

no problem. For some good help on modding that thing its a good idea to post in the evo section and check out some of the faq's. There is alot of good info there

RE: Dumb Question But I Need Help
 

Seb its def what happens. the Evo VIII stock BOV is so bad that yes a new BOV will help spool a little quicker and of course hold boost higher in turn making the car faster. just go listen to my videos of before the BOV and after you can eve hear the difference up top in the exhaust note. (of course Im talking pre turbo upgrade and cams)

RE: Dumb Question But I Need Help
 

I knew it was a POS... but DAAAMN

RE: Dumb Question But I Need Help
 

i have a rs bov and it doesnt make a flutter sound....loosen it up to where the bolt is sticken out about 1/8
