I just ran my pump gas 610 on the dyno. The build used a stock 39 fcr, stock pipe, stock filter, stock valve size, 10.9 compression, and stock air filter, my porting. And it made 58 hp at 7600 and 48 ftlbs at 5200. It also made over 50 hp from 5400-9400 rpm. I ran this on a dynojet dyno on pump gas. I will have my other 610 on the dyno in about 2 weeks with a pipe, 43 fcr, bigger valves, bigger cam, and higher compression, my porting, and a few other goodies. I think I can reach high 60's hp with my race gas 610. I will keep you guys posted.

Sounds awesome and powerful. Did you happen to dyno it stock to see the increase?

Posted by: Sparky YFZ

Yes it made 36 hp bone stock just off the showroom floor.

Is that HP or TQ? Racers Edge, a shop in Tucson AZ just dyno'd a totally stock 450 and they show'd 45HP & 33TQ. I'm well aware of dyno differences and how a dyno is only a tool to show differences between modifications done on the same day with the same temperature and barometric pressure and yada yada yada. . . . . Just curious if you got 22 additional HP just by putting in the stroker & bigger cylinder?
Either way, thanks for posting the info. It's nice to see more and more builders taking these quads to the next level. I love mine and will be doing some engine mods once my pipe is completed and all dyno runs are done.
And please, let us know how that 610 did with your additional mods (pipe, porting, valves, etc. etc.???)

36hp and 30.5 ftlbs on a dyno jet dyno at 4500 ft and 55 deg.

I have made MUCH higher #s in my other 610 with pipe, carb, + valves, and a little more porting. Im still testing this build to see how well it will hold up. Before I will sell this combo. Big #'s dont matter if they wont make it to the top of the dune.

All the mods are stroker crank, big bore 11.1 comp, my grind cam, and my porting.

Does John own Racers edge? If so he has seen some of my stuff run at Sand Mt Nev.

the 36hp is the 450 right? or the 525
