Lock out timing on E85?
Those of you running E85 on your race cars, do you lock out your timing?

yes, locked, however, I have scrapped a flex plate or two. as long as your ignition is on a switch where you can get it rolling and then hit the ignition should be fine. This seems to work much better than a start retard, for me atleast

I have my 4 cyl locked with 9 to 1 With no problems.
My 461ci is 11.3 to 1 with 92 octane and that one gives my hassles with out turning the ignition off while cranking...

locked out
my 12.25-1 461 on e85 has it locked at 36 degrees. I did switch to 16 volt on a Robb mc started to save flywheels as the start retard and cranking then hitting the ignition on button was not working for me. when it was on 12 volts it cranked fine but would occasionally kick back and knock teeth off flywheel. did the same thing with timing locked or unlocked just for reference.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
