FoT,
I need some input regarding the use of roller rockers on a race
prepared TR6. If you are running a cam with .500 lift and 300 degrees
duration, does the use of a higher ration roller rocker (1.65) really
add that much more power? This is assuming that the head is well ported
and you are running the largest intake/exhaust valves that fit in the
head. I was just made aware of some engine testing recently that
indicated that there was only a 2 h.p. gain by using roller rockers
with the above modifications. It also indicated that the increased
ratio caused more wear on the cam, tappets, etc. The logic as presented
seems to be that you can only draw so much flow through the head
before you get diminishing returns. Any thoughts on this?
