Well yeah, thats definitely not the tires to dyno your bike with...yall need to go run er again and let us know what she pulls.

 

a 60hp stage 3 would be dead on. Many a RW stage 3 have made that number, in fact, that's what his advertisement graph showed for a stage 3. Is your graph up somewhere, we can take a look at it.
Do keep in mind, that 6hp loss is an average on a stockish bike- it varies from run to run (very inconsistent on knobbies) and it depends alot on the amount of torque the bike is actually making as to how much loss there will be ( the more torque and the faster the accel rate of the engine, the more slippage). So, don't write that 6hp number in the front of your Bible.
222

 

so the bigger the motor " more hp" the more slip with the knobbies?? usually right? 222 do you use a brake on your dyno? when getting the final numbers??

p.s. so basically the dyno #'s that we have are not worth looking at other than tuning the carb...???.. thanks randall!

 

If I was an engine builder like Kenscycle, craycraft, woods or HPR, I'd find me the "friendliest" dyno I could to show some awesome numbers for my kit. Then I'd find a lot of reasons why those numbers couldn't be duplicated on MOST other dynos so that nobody would be disappointed. They'd still have the big numbers but you'd have to get them a very specfic way.

 

OK, a stage three Woods bike is 60 hp, what i'm seeing is an 11.5-1 piston, a1-a2 cams, and a ported head with bigger valves is worth 2hp over bolt-ons with a drag pipe, Is this correct? If so opening a motor is a waste of time and money!

 

the dyno #'s out there on any bike are not a comparison platform, that takes place in the sand, boils down to set-up and driver, build it how you like, line up and have a good time, see ya'll at Sandfest ![img]i/expressions/face-icon-small-smile.gif[/img]

 

XR650warrior, what days are you gonna be there?

 

also the kit that made 53hp with the lectron, intake and end cap, was 42 on the dyno at little sahara. so some are using the brake and some must not....????....

 

Actually torque slips the knobbies not horsepower. When the tires are slipping you can not get accurate O2 readings for carb tuning either.

 

misterhp do you use a brake on your final #'s???
