Can anyone tell me what figure you would use as a calculation for flywheel horse power....
I know it won't be accurate, but it would be a way of telling how may car compares against others....
If it makes a difference, i'm running an STI V7 6 speed box and diff...

my figure would be at the hubs!

multiply wheel figures by 1.18 is close

what did you get then Mike?

If using Delta Dash mate, add 16%...

Or if youre like some tuners... add 25% ha ha ha

It was a hub rolling road run.... not delta dash, but direct hub figure

Sounds pretty good, but numbers aside...

How does it feel for you as a driver?

drives great, with more to come i know.... a slight hesitation, which the curve seems to show.....

Thats good,

On the road, my 303bhp ATW equated to 351bhp using 16% and 377bhp using 25%.

So yours producing some 15bhp more should be well up there.

In a little light classic.. thats pretty damm good in my book

Mike's figures are hubs fugs so wont have tyre losses in there so I would expect that the 18% would be less.
