[Fot] Distributor centrifugal advance curve for race engine

[timmmurphh at gmail.com]

What advance curve are folks using in their race engines? I have 87mm
pistons, a Kastner G3 cam and about a 12:1 compression ratio. I am using
about 19 degrees advance at idle (no centrifugal advance) and 30 degrees
advance at 3000 RPM.  I don't know what I have at higher RPM's because I
never looked. I'm currently doing an engine rebuild so I will have to look
what I've got at the higher RPM's when I get the engine running. I'm curious
as to what others are using and if anyone has done any testing on a dyno
with different advance curves.

 

Thanks in advance for your input.
