Tony, what type of fuel did you run on the Dyno? What plugs are in the motor?



Harley - Sorry, I missed your questions earlier. NGK plugs and 93 octane from Citgo gas staion.

I think next time I will try the 1 3/4 headers they had. It would have hurt the peak HP numbers, but it would have given me a better idea of the true torque curve. Or better yet, maybe my engine guy should get a a set of 2" headers for the dyno Those 2 1/4 x 4 inch sewer pipe headers have got to be screwing with my torque/power numbers. Has anyone(AndyF!) done any header size testing before??
