I have recently installed a new 415 Stroker, big blower Cam, and a Procharger D1SC. My problem is my vacuum is extremely low do to the big cam and this is causing my blow off valve to not work well. I had originally installed a new Greedy type FV 40mm, but even with just the lightest springs I still couldn't get it to work. I finally found a BOV that is working, but I really need to use a larger one. I've read that by installing a racing vacuum that there are some good benefits and that they can actually give some additional HP. I'm wanting to install an electric Air pump. Have any you done this & fix it help. Thanks

In the old days we would install big or bigger vacuum canisters ??????

Tial makes bov's that will open for you. Tial is considered to be the best bov for any application by most forced induction gurus.
