Listers:
As a result of winning a silent auction at a local benefit dinner the other
night (I was a little deep into the hops and barley), I find myself the
"owner" of a certificate for 1 hour of chassis dyno time. Now I need help!
Since the racer 1275 Midget runs SU's, there's no jetting changes I can
fiddle with. I have only one set of alternate jet needles (the Cooper S
spec needles recommended on the internet needle chart for a 1275 with a
little porting, header, and moderate cam). Timing? Well, I guess I could
screw around with that, but how do I know if I'm detonating with all that
racket coming from the motor? What else?
How do I make good use of an hour of dyno time? Are there any parameters I
can manipulate within the constraints of the dyno session, or did I really
buy just the opportunity to see a stepped readout of HP and torque at
mounting RPM?
Open to any advice and input from those in the know. Bob Kansa: I know you
can help me!
