dyno percentage loss

Post by ktmkazza93 » Wed Mar 14, 2018 9:01 pm

hey guys just reading on dyno chat there seems to be alot of diffrent numbers for duke gt 146-148 on diffrent forums.i know diffrent dyno conditions ect ect but surely mid to high 140s is alot of loss. I hear 10-12% is 18 to 20 bhp loss is more realisticso 25bhp and up loss is a lot dont u think from 173 at crank i heard that almost shaft loss??? .

When mine was on the dyno I had the Rotty stacks and air box with Pc3 and my GT made just a hair under 150 hp and 90 ft pounds, the dyno op said if I yanked the Cat I could maybe expect another 7 to 10 hp. He also said the stock muffler with Cat out worked quite well.

Hi all, losses are losses....... chains have to be just right (clean & tensioned) tyres not worn and correct pressure, air filter perfect, new plugs(?) oil etc etc for a perfect figure. Maybe the other forums prepared their GT's and maybe they just hooked them up and did a run...... also, the motor needs a few kms/miles on to loosen up and give full hp figs...... I was talking to a guy who got 200hp out of his ZZR1400 Kawasaki and the detail he went to to get a good result was worthy of a Gold Medal :lol:

Now Healtech has their ESE (exhaust servo eliminator) out, more cats might be shelved for link pipes and 10 more hp's ..... :mrgreen:
