I am assembling/ building a procharger system and will be running the D1SC. Not sure what boost i will push with it, but knowing me I will be running it as hard as possible at some point. My question is why does everyone run prochargers race bov instead of another brand like tial? It seems you can find the Tial bov's for about half the price of a procharger red raceing bov, so am i missing something? What bov would be recommended for my application?

Do a quick search bov vs bypass valve. Big red is a bypass valve and is used specifically for supercharger applications. Hope this helps

I ran a tial 50mm bov for a while on my lt1. Had to get a custom spring that allowed it to open at idle. Worked great. Can't use it with a maf sensor though.

why couldn't you run a maf?

Basically what i could find reading other posts was you can run a BOV but you need a lighter spring so it is open under vaccum (at idle etc...) then closes under boost. A couple people said that Tial had supercharger springs for them, so with the right spring i'm assuming it will work and thinking about going this direction since they are so common and much cheaper.

I guess you could run a MAF if it is AFTER the BOV. This way if the BOV releases air, it is un-metered air.

Oh okay i see what you are talking about. I was actually planning on installing either the BOV of the bypass valve before the intercooler. This way it releases the pressure before it comes back into the blower, and also so you aren't heating up the intercooler with air you will not be using anyway. not sure if this is how most are done?

TiAL

correct

maf before the bov and it goes pig rich and idle surges/stalls

TiAL

when you dump pressure, it doesn't matter where it is as long as the air can escape

put the bov where the vacuum line will be the shortest

i have procharger D1 on my 395 stroker. Have oil in charge pipes. Would like to install BOV. Is this possible and would it help?
Also..is there a kit? I have the Dual intercooler set up.
Thanks

I'd like to bump this back up. I have read more about people using the tial 50mm BOV on procharger kits, but they have to use a special spring for it to work properly. What spring should i run with a supercharger. Thought i read -3, is this correct? I'm seriously considering running the tial bov instead of procharger bypass since it is $150 cheaper.

I run the Vortech mondo BPV on my setup. Its cheaper then the red race valve and works just fine. I ordered mine off summit and it was like 300 for the valve and flange. A BOV with the right spring will work too. The more boost you run, the bigger the valve you need.

you need a catch can sir.


your dual intercooler should already have a bypass valve, its that little black thing with the linkage on it. thats ur BOV/bypass valve. i guess you could run 2 if ya wanted.....

He needs a catch can and a properly routed PCV system.

It looks like there are a few out there running a tial with a supercharger, but was wondering where they get the special spring for the superchargers at? I don't even see it listed on Tial's website.

you just need to specify it's for a blower at time of order and need the hot pink spring
