Cruisin through the "internets" and came across a new Greddy Type FV BOV

FV standing for "Floating Valve"

Thoughts? Has anyone pre-ordered/ordered one?

 

Looks promising, should be interesting to read the reviews.

 

^^ Reviews are usually good but you can't trust them all. Best bet is to find someone who already has them and see whats their take on it.

 

looks original and interesting but not obvious that part throttle boost control will be any better. i'm mildly interested in trying one, but my Cobb valve works too well to bother.

 

. I don't immediately see how the second spring really helps. Is it not just a second spring right between the plunger and valve body? Does the valve body slide?yes appearantly Is it a reincarnation of a hks ssqv?

I do agree with greddy's piston to valve area ratio though. And they tend to make a valve that drives very well. I also set mine to be light on the seat at idle.

Actually it looks like the plunger is short almost even with the valve body and the diaphragm unloads the top spring under normal vac and the boost in the pipe only has to overcome a light spring . Makes sense to me now and seems like you could make a standard type valve into that easily.

 

Yes...but will it have the little bird fart sound like the RS???

 

Anyone try this yet? I'm with te don't fix it if it ain't broke idea but my type s is getting old and the rubber will tear sometime..

I also like the recirc option as the type s didn't lend easily there

Gasp.. I might jump to a tial.

 

I think we can set up the main spring pretty soft due to added floating valve spring, so when there is only one spring, the optimum operating window was relatively small to ensure closed at idle and open freely at even low boost, but this one should have larger window theoretically.

I like the fact Greddy BOV has diaphragm style like stock unit, so no need for oiling maintenance of metal piston type BOVs.

I might try this one when my GFB StealthFX is degraded, but it functions well, and I do like this adjustable vent to air ratio feature (Cool sound and minimal impact on driveability in another word. )
