i am currently running around 20psi on my car, (on high boost). but even on low boost my BOV surges. i have heard that this is bad for the life of the turbo. i have a greddy type s BOV right now. i am looking for a new one that is made for the boost that i run. it will need to hold 25psi for when i take it to the track as well. i would like something different like a SARD BOV, are those any good? i just need one that will be good for me.
thanks

 

You could always move up to the Greddy Type-R. I would recommend the TiAL blowoff valve. The machine work is very nice and it has a 50.5mm valve. My TiAL should be here in a few days.

 

for ease of operation, the best would be to just go with a greddy type-r. you wont' need to swap blowoff valve flanges that way. ive seen 600 rwhp supras with t66's use type-r blowoff valves, without much surge problem at all.

 

Hks Super Sequential is wat im goin with soon, it should do it , its made for high boost

 

thats weird...i've run 23+ psi on my greddy type s with no surge issues....anyway, i say go for a greddy type r, it'll save some headaches

 

thanks. i heard that the super sequential flows the same as the type s though.

 

If you look at the supras with the hks ss they have two of them one one each side of the pipe. supras normally use the hks racing bov
