With a solid "street" roller with approx the same specs as the one Brian used there would very little if anything in it. Virtually all the dyno programs inputs don't differentiate between hydraulic roller and solid roller, why do you spose that is? I will admit if you have a VERY serious engine that makes power at high RPM a solid roller is a better choice.
It would be interesting to get Brians views on this 'leaving 100 HP on the table statement'
