James that was at wheels wasn't it?

 

I could be wrong but I believe that was flywheel HP. Only difference is it was calculated using the 6speed transmission losses rather than Auto. The auto losses a bit more so the figure is actually higher than the graph, hence James adjusting the calculation for his actual HP figure.

 

It's definitely not ATW though.

may i ask please, what conversation figure do you use to get flywheel BHP. obviously the DYNO you was on reads at the wheels but for some reason always gets converted to flywheel.

 

 

Do you all know what your true wheel bhp is?

 

My wheel hp was 594 mate. Tdi say auto lose 20% transmission loss so flywheel is 742.

Nice work D :thumbs:

 

RE: auto's, I think the numbers can be real messed up especially when the car is running a hi stall. Torque Convertors = Voodoo on the dyno IMO :D

 

Absolutley mate, the hi stall doesnt help give the most accurate reading until after 4k rpm when its not being used :)

 

(sorry to clog up your thread Homer!!)
