hi does anybody know where hp ratings are taken rear wheels,flywheel,???.the 2008 vette is said to have 430 hp thats 8% more than a 2007 , a big increase or a change in the way hp is measured?i know that hp measurments have changed before ,has this happened again? in the 60's hp was on a engine dyno at the back of the crank if i remember correctly,then i recall something called brake horsepower,and of course rear wheel horsepower measured on a chasie dyno anyone know what is the standard now and do all factorys use the same rating system[i see tv ads for 250 hp 4 cyl toyotas ]
