Torker 2 vs Performer RPM?

As for the intake. typically a single plane intake will work best above 3000 rpm, not very good below that. Its a total combination of all the parts. A few mismatched parts and the car will be a dog. You will spend forever chasing it with new parts. This is why i used to hate the car magazines that lied about combos and ho fast the cars went. now the internet has take that job. Go speak to a reliable engine builder who has built performance engines and get him to design a motor for the application your seeking.
