Must be Rod Coon.

If the test is conducted properly, there should be little difference. it really depends on how fast the drums or axles are accelerated. a dynojet is worst case, because it takes into account some inertia. brake dynos do not, so,in theory, they should always be higher for a given car. but, its also why drum dynos are done in 4th gear with large heavy drums so the factor of the inertia is factored out for the most part.

i did 335 several times with the holbert car stock 5 liter, but after many years it stablized at 320rwhp.. same as Rons GT with the exact same mods (i.e. no cat, but headers and exhaust)

291 is the rear wheel hp number. where did the 311 come from?
