I have a ap1 with the comptech aftercooled kit. and i was wondering what aftermarket blow off valve will fit. i want a externally vented one. maybe hks ssqv?? any help will be greatly appreciated

 

why the hks one? sounds like someone is shooting a laser or something. the blitz one is loud, the greddy one sounds ok, the sard one sounds crazy. never heard the tial one yet...

 

I think the HKS ssqv sounds good.....also it's probably one of the most well designed ones for higher boost street applications. As far as the "most venting one" it's not critical to have a high performance BOV on a SC car, because there is no real fear of overboosting. Just get one that you like and someone can make a flange to fit the car

 

This is about the 3rd time I've put this out today.....

Anyways.....

The Turbonetics Godzilla BOV will work with the stock Comptech 4 bolt flange. Any other BOV will require modification buy using an adapter flange.

Here some pics of my old Godzilla setup.... it was loud and had a "Swoosh" sound to it... I turned the horn downward because of the constant venting was annoying....


Here is my new set up with the Greddy Type S.... This has the "Swoosh..Tweeeeet" sound. It has a very distinct high pitch whistle that the Godzilla did not. I like it...




Don't hack on the weld job.... I didn't have many options for aluminum welders at the time..

If you want to use a two bolt Greddy BOV you will need this flange


Hope this helps...

oh that help a lot! i was wondering about that cool

 

is there any other vaccum lines i have to run to get the bov going?? i am leaning towards the turbonetics one just for ease of install thanks for pics too!

 

Yes.....the vaccum lines run as such....

 

There are different outlet diameter size, which one will fit the Comptech A/C ?
19 mm 11900511
29 mm 11900512
32 mm 11900513
34 mm 11900514

It's NOT an "Outlet Adapter"........it's the "Aluminum Flange". This is not a Turbo set up.....it's for your Aftercooler.
