DYNOTEC tuning/ DAS-Mototec tuning

[Dimitris]

Hi!!

 

Haw anyone tuned his bike with Dynotec? Or DAS-Mototec? They offer some upgrades for our bikes. They speak for good power (108 hp) and torgue (115 nm).

That must be at the crank, right? I don't want to hi-jack your thread but hopefully this is a valid inline question to go with it: Do anyone know the ballpark figures for transmission loss on a V11? If you've got 100 hp at the crank, what could you expect to register on a roller dyno?

Transmission losses are typically about 15%. 100hp at the piston crown should net you about 85hp where the rubber meets the road. Again, this is typical; some bikes are down around 10%, some as much as 20% [some of the shaft driven transverse Japanese fours are in that higher bracket, since the power goes thru two 90deg turns...]

 

In terms of efficiency, a freshly lubed chain drive is best. But tests have shown that chain drive bikes lose their advantage in as few as 20 miles [back in the day, before o-ring chains. Much longer nowadays.]

And what is your opinion on the losses with belt drives?
