I don't buy the % of loss. I believe that the parasitic loss is a number. True you can make it a percentage, but that is a meaningless statistic.

Vendors hide behind the veil of mystery by making flywheel HP claims that cannot be measured, but sure sound more impressive...
I agree with you John, It is just a number that people use.... I think the only way a person could come up with a "real or close" number would be to have a motor dyno'd on a motor dyno and then dyno the truck after installing the motor, then you could have a close number for that truck I think.... I know that dyno's very from one to another, and the numbers need to be looked at with that in mind....
