This is exactly what I’m looking for, I’m going to speed density and too much boost for my 9 mr bov so if you have one of these setup for vta, message me. I would prefer if you have the bottom flange but if not, no biggie. Thanks!

I also have a ton of stock Evo parts for sale that I will post later on today. If you’re looking for a stock part for an Evo chances are I have it ready to ship or get picked up.

You should get a tial 50mm instead…

Tial is way over rated, the GReddy I can set perfectly on the fly for the amount of boost I’m running. Tial’s are known for compressor surging so I’m going with the GReddy. I used this exact valve on my dsm years ago and loved it.

I’ve never seen compressor surge with one as long as you use the correct spring in it, and it’s the BOV of choice for pretty much most speed density users so that in itself has to say something. But good luck with the greddy and if I see anything ill post it here.

I know I can swap springs out quickly and all but then I’d have to sell my current GReddy upper ic pipe and go with an STM style short route, then spend the big bucks on the tial, I’d much rather just stick with what I know works for me. Thanks for the input though, Tial was my original plan until I learned about the compressor surge issues, the GReddy is incredibly easy to adjust, no spring swaps needed.
