Thats odd, i fully believe your car is this power @ wheels and fly

but

As i've always been told that, Ava said 100 bhp losses on a 4wd (let alone 2wd) was unbelieveable, as that sort of transmision losses would melt the transmission.

also on previous decussion about this some of Ava's customers said a 4wd car would only have 30-40 bhp losses on a 500 bhp engine.
this "comparrison" was done by me and not by anyone at AVA.

they dont think my car has this power but quote about 30 hp more for a fly fig but are not intersted in fly figs at all.

im only going by what i have seen on other cars that have been on ava rollers after being on a dyno.

ie mike rainbirds saf made 515 on harveys dyno and 395 ATW at AVA.
Andy Gallaghers escos made 612 on harveys dyo and 484 at AVA.


bear in mind both mikes and andys cars once fitted into the car have restrictive exhaust systems and all other related losses(alternator,higher charge temps etc) along with transmission.

i stand by what AVA say and agree that massive losses thru transmissions are impossible
take from this what you will..

Ok, So you have a 440 bhp/fly T4 cossie set up, thats abit poor then really, i mean 450 bhp was being done on std RS500's with a 8inj mod and a remap in the mid 80's.

As for Mikes car, 515 @ Harveys, - 40bhp for in car fitment, -17% trans losses = 395 bhp/whe, which all seems correct.


Has anyone run a car at a different RR and then @ Ava?
as i guess the power/ wheels will be the same
get your car out out and ill show you how poor my car is
