Best recirculating BOV for 400+ BHP?
HI
I need a new BOV for my 425 bhp hawkeye sti.
The car has a FMIC so can either be a universal fitment one attached via hosing, or a Subaru specific one in which I can buy an adapter plate.
Which is the best recirculating valve to handle the high boost pressure of my car?
Not interested in vent to atmospheres of any kind.
Thanks

Can you guys send me links to the forge ones you have?
I know the standard ones are good but I want something uprated that I know will handle the uprated boost
Cheers

Thats the same one I have now, how do you turn it into a recirculating valve? I'm boosting at 1.6 bar 425 bhp

I run forge on my track toy. You'll need one of these for yours

I like the look of these and aren't a bad price. I see they do a FMIPCV valve as an optional extra which would come in very handy.

i took a punt on one of the China Tial QR's - for £30 delivered. its literally the same bar the brand naming. even when disassembled it had the same diaphram/cylinder assembly.
only thing i found was the hexhead screws where a bit soft so upgraded them with some Tial screws which werent exactly expensive either
and seeing as there aint a lot of engineering behind them i thought it was worth a punt....been on for 6mths now with no issues at all - we even ran it up to 1.7bar at one point
just about visible in this pic

the turbosmart spring is adjustable, soft to hard, adjusted by turning the cap. On installation they recommend starting at the softest setting at idle and turning clockwise toward hard until the car idles normally, in effect the softest setting you can get away with. On boost it relies upon equalisation of pressure either side of the piston to keep it in place. The OEM DV relies on a very hard spring to keep it in place when the turbo's at max.

Interesting. Still tryin to decide, I'd say it was probably between the tial and the turbosmart on now as they are guaranteed to hold boost up to 600 bhp. Tial is significantly cheaper too...
