Here is a dyno run from a CPC
246 (240 big bore w/ a 4mm stroker crank). This run is from the CPC
rigid drag blaster shown on this site going 4.5's. The 60hp pull was on
motor and the 73hp pull was with a 16 shot of nitrous. If you look at
the nitrous pull graph you can see the gearing line with a large dip in it.
That is indicating that the clutches are slipping very bad while spraying
nitrous. We have not been able to run the bike at the track with the
nitrous due to the severe clutch slippage problem we are dealing with.
We are running a lock out with new clutches on that pull. We are still
working on fixing the clutch issue so that we can run the bike at the track
and get some even faster times.
 Here is a dyno
run from a local customer with a CPC 240 big bore with a 6mm crank. You
will notice that the clutches are slipping by looking at the gearing line with
the large dip in the curve. The bike should make in the mid 60's once
the bike gets new clutches and gets back on the dyno.
