Curve
A
shows a clutch set up with three 10-gram
type roller pins. This amount of weight will govern
the engine to 7200 RPM and allow engagement
of the clutch at 4000 RPM.
Curve
B
illustrates the effect of exchanging the
three 10-gram pins for three 14-gram roller pins.
The additional weight has virtually no effect on en-
gagement speed but pulls the peak RPM of the
engine down to 6800 RPM.
Curve
C
illustrates the effect of using three 16-
gram roller pins. Again, the additional weight has
little effect on the engagement RPM but further
reduces the top RPM to 6400 RPM. For example,
by adding 2 grams per arm for a total weight in-
crease of 6 grams on an engine turning at around
7500 RPM, there would be about a 200 RPM de-
crease in full power engine speed — approximately
the same effect as going 1 clicker position lower.
On a high RPM race engine it may only take a 1
gram, increase per arm to see a 200 RPM de-
crease in peak operating RPM.
