Dyno

[tinbender0]

The dealer did my baseline dyno in 4th gear. Which rwhp was 149.59.....I had it done again (for free) the other night at a local bike night..This guy did the bike in 6th gear. Anyone know anything about this? If he would have done it in 4th would the outcome be different? The bike dynoed at 153.6 this time....I would have thought it would have been a little higher since I've added a few things. Yoshi slip-ons, power commander and map, and a K&N air filter..Help

Dyno pulls in 4th. The mods that you have will add at most 4-5whp.

Don

You will make more whp with the stock filter. I have a K&N in mine as well, but it came with it.

wonder why the guy ran the dyno in 6th? jeeze,,why will the stock air filter make more power? K&N says mo power??? false advertising huh...

6th due to the load (dyno is torque converet to HP)
6th will always give you more.
also remember how the bike is position on the drum, tied down, rear tire condition pressure and type , all play a factor and the most important on is operator and correction factor

what's the formula from hp to torque?

 

[Johnnycheese]

T = 5252 x HP
----------------
   rpm

 

[gazza414]

thats "divided" by rpm

oh yer max torque isnt at max horsepower if thats what you might of be wanting to establish
