Just wondering what 1000rwhp would be at the crank? It's running a built ZF. Surely someone has done both. Cheers. Link to comment Share on other sites More sharing options...

Most converters will have no slip cos the stock tune keeps them locked. In this case 1000hp atw will be 1140 at the crank. 1 Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

It may as well be a manual trans for that comparison. Link to comment Share on other sites More sharing options...
