  • roller cams

    sorry for the dumb question, but what is a roller cam, and what are the advantages to them? i've heard that they were in the aspire and not the festiva, but what is the difference?
    Thanks!

      the odd thing here is the factory festiva flat tappet cam is more agressive than the aspire roller cam.

        Correct me if I'm wrong but the aspire cam is a flat tappet cam with roller tip rocker arms

          It is more aggressive, but less friction from the roller yields a better gain on paper? Is that why the aspire's engine is rated slightly higher? I brought all this up in the hijacked b6 manifold thread, trying to figure out if fitting a b6 with aspire's upper valvetrain is worth it. Since I do not already have a b6 in hand my conclusion is no.

            Did you ever get an answer to this question? I have the B6 head currently with solid rockers, I have the Aspire valvetrain sitting on the shelf and I have the FMS cam on its way.

                no, it's a steel roller cam.

                  By more aggressive, do you mean higher lift, longer duration, more overlap? Or the rate of valve acceleration?
