Re: NGR Type S BOV
oh, gotcha. You made it sound like a hybrid. So it's just a loud recirc. Some of that depends on your intake piping too, because that can really amplify or muffle the volume depending on the piping material, etc.

Re: NGR Type S BOV
And like anything else, if the racing world (probably WRC in this instance) hasn't latched onto a turbo system component and refined it to within an inch of its life, it probably isn't worth doing. I know that's a lame argument for anything, but most things trickle down from motorsport down into street cars, not the other way around.

Re: NGR Type S BOV
no its a bov that i recirculated. a hybrid valve does both, recirculates back into the intake and blows off into the atmosphere. most of thoese are adjustable as well.
i know turbosmart has one and i think forge motorsports does too..
but either way NO the ngr type s is a bov that can be recirculated. like the greddy type s, type rs, hks ssqv, etc. cept all of those have a muted sound when recirculated. not the ngr type s.
heres a pic of how i have the hoses on mine.

haha mines a custom setup, im fine w/the hoses and not hard pipes. it doenst affect anything except itd be louder with hard pipes.
and its $130. email them at ngrperformance@gmail.com

Re: NGR Type S BOV
Silicone works great, lasts forever, love it. Easy and cheap. There isn't anything wrong with flexible hoses for a BOV, and airflow is much more affected by internal area than by internal surface finish. Besides, in this application the duration of the flow is so short that you can't even remotely worry about the same things that affect steady state flow, like boundary layer problems, etc. Hard pipes look more finished and professional, but that's pretty much it.
Why would flexible hoses matter? Is someone going to jump in and argue that the internal volume change of a short, small diameter piece of tubing is going to somehow affect turbo system performance? I could probably show that every silicone coupler in the main piping system has more compliance than that one piece of tubing, and then there's the argument of why none of that actually affects performance...

Re: NGR Type S BOV
Lemme know how that works out, greddy type s has been on most of my cars over the years. They are getting harder to find. It never leaked on me but i never ran more than 22psi on my type s. and while it may be rice to pick a bov based on sound type s sounds the best by far IMO
