If you mean why is the torque figure so different from the power figure it's because the power figure is at higher revs than the other cars.

bhp = lbft x rpm / 5252

Check out peak torque and power figures for an F1 car. Silly revs makes lots of power with relatively low torque. The same goes for most bikes.

hi kingsley. no mate the power. on the thor graph car made 519bhp @ the hubs. at well lane made 518 @ fly????.
looking at that thor dyno it looks like 446 at the hubs? which would work out about right for around 510-520 at the fly ;)

what hks turbos are you running? if there 2530s then 450-480 ATH is about right for them :)

I thought that Mike but on the Thor printout the TCF is set to 1.00 which, if I remember right, is the compensation factor. At 1.00, it's not adding anything for transmission losses but simply reading out what it measured at the hubs.
