I'm running a Paxton Novi 1200 on my truck right now. The kit came with a cheap, plastic, bypass valve. Who makes the best one's out there?

 

Magnusson!...silly

 

See if you can find a used ATI Pro-Flow. That is the stock one that the Procharger uses. It has a 1.5 in diameter. It does a decent job but does tend to leak a little boost because it uses a butterfly valve. Some people with the ATI have to upgraded to a vortech or the vortech mondo, so you should be able to find a used one.

 

I just checked on the Votech site. It looks like the Vortch Mondo could be a good canidate. I couldn't find the Magnuson site. Thanks

 

I have the vortech maxflow racing bypass and I have no complaints. Sounds cool too.
I picked it up on Ebay for $100
