Some dyno's monitor drum speed and compensate for different gearing. Correct me if I am wrong, but it would seem to me that a dyno that didn't have that capability would show more relative power from a bike in 4th gear than one in 5th. Also whoever was running lower final drive would have an advantage.

 

Sounds like the dyno you were on would do a stocker at around 36-38 You've got good increases from there. Thats where the dynos around here put us at with similar mods.

 

This dyno gets 32 hp from a stock yfz. And probably 32-34 from a stock ds.


DSNUT- We both ran in 4th gear.

 

a stk yfz pulling the same as a ds?? at little sahara they where about 5 diff.

 

Yea it was a good day. On the same dyno but in a different location, my stock bike ran a 32rwhp and with pipe and RWR CDI. With my stage two from RWR I ran a 46.

So I gained a peak of around 11hp. that was not the impressive part though. the impressive part was the graph that the dyno plotted. Between 6400 and 7800 I had less than 1.5 variance in HP. Compared to my stage two, I made almost 18ftlbs more torque and at 6250 made almost 17ponies more than before. Obviously I'm making a great deal more power with my 730 and was EXTREMELY happy with the numbers.

As far as Mario's numbers are concerned. I touted this motor a month ago, and let you folks know that this stage 2 from Bigger is INSANE. It is for sure.

Also know that Mario is running an HPR drag pipe which is probably good for about 4 - 6 ponies. No excuses, his sled flat out hauls can!!!!!

Props to Tony over at Quad Mania. We spent 4 hours in the shop doing what ever was needed and the price was absolutely AWSOME!!! go see Tony, he definitely looking to help serious quad guys out.

I got you next time Mario....

I'm bringing a little sumthin' sumthin' to the table.

 

LOL, Mike I got sumthen too. all motor... And I think we should change out pipes and run them again. [img]i/expressions/face-icon-small-shocked.gif[/img]



You know your bike hauls too. Thanks for the props on my rig. Your a feakin mechanic yourself so you have the upper hand. ME?? I dont even know how to change the spark plug...[img]i/expressions/face-icon-small-wink.gif[/img]

 

Were you running alcohol or race gas, annihilator? What compression? How much advance?

 

That says alot for DSMIKE and BIGGER. I believe this motor is a couple years old.[img]i/expressions/face-icon-small-smile.gif[/img]

 

110 octane


180 PSI when we did a comp check


about 37 degrees advanced. Dont quote me though.

 

That is impressive bigdaddy, Those are some very good improvments over the stage 2. I would be happy also.

And I believe that biggers motor was built more then a couple of years ago. He will have to chime in here and let us know for sure.
