I found this thread while cruzin the Viper board. In case this doesn't 'post', the site is pumaracing.com The Viper 'thread said, based upon this site, that to guesstimate rear wheel H.P., based upon ADVERTISED flywheel H.P. : multiply the Flywheel H.P. by .88 and THEN subtract an additional 10 H.P.--seems reasonable, to me.
