+1 on alot to read and focus my attention. Most are on dynojet and a mustang dyno can show less HP, but they're so many factors. i've seen a ford focus dyno a certain number on a dynojet, then it was later dyno'd on a mustang dyno, thinking it would put down less when in fact the HP numbers were higher than the dynojet. Usually it's a 10HP decrease from a dynojet to a mustang dyno but all the factors will make it vary. Just like when people dyno from SAE or STD, usually STD will add about 10HP more, but the factors will play a part too.

you might dyno 300rwhp and another car will dyno 280rwhp, you take them to the track and the 280 gets a better time and beats the 300, so...you might make certain numbers to the wheels but its all abouthow you drive it. Numbers to the wheelsis one thing but the 1/4 is what i'm concered about.
