Anyone had their engine dyno'd and had it roller dyno'd and compared the difference?

 

Just wondering what 1000rwhp would be at the crank?

 

It's running a built ZF.

 

Surely someone has done both.

 

Cheers.

ZF has 14% loss, you can measure converter slip via road speed, rpm and gear ratio. Most converters will have no slip cos the stock tune keeps them locked. In this case 1000hp atw will be 1140 at the crank.

Wow that seems like less loss than a lot of manuals were getting.

 

Has Anyone actually had the same motor on the Engine Dyno,

Then measured at the hubs or wheels and compared the difference? 

 

Am sure someone on here would have....

 

Cheers for the reply.

The more data the better.

The zf doesn't slip in gear when it's operating properly, all the relevant clutch packs are locked and the converter is locked. It may as well be a manual trans for that comparison.
