Default blow by valve

hey guys, i'm about to up the boost on my vortech supercharger from 9psi to 16psi. how can you tell what type of blowoff valve will be best for your type of application? i was looking at the one vortech sells but its almost $300 and moneys always an issue.

If you want a vortech piece it's going to have to be the mondo valve at 16 psi, and yes they are $300. Are you running blow thru?

i don't want the vortech one only because of price and i am running blow thru. i'm thinking of ordering the cx racing universal intercooler kit that comes with a blow off valve but i heard there could be tuning issues with that since there more geared towards turbos

Im not sure how much boost those cx racing ones can handle. Honestly when running that much boost a BOV is not somthing you want to skimp out on too much. Because if you get one that cant handle the amount of boost you are running you will force that air back into the blower and cause compressor surge.

I have seen a few threads about your setup, do you have any pictures of it? Im interested in seeing your car.

yeah man, save up and wait and do it right. Im guessing you have a built motor and a good amount of $$$ invested into it...not a smart move to skimp out on a part and save $100 bucks when it can cause more harm than good. You dont have to get the Vortech Mondo, as there are other options out there but I would wait and just save and invest into a good valve

I did alot of wire tuck on my old car. I went so far as to cut open the harness and reroute wires to make the wires barely visible.
