So the dyno results are in, The 405 stroker made 30.7 Hp and 27 Ft Lbs. to the tire. I have 25" GBC dirt Devil AT's. Peak power was at 6,500 rpm and peak torque was at 5,000 rpm, however the real tail is that this motor held over 25HP to the tire to over 9,000 rpm, was still making 23hp to the tire at 10,000 rpm, and finally the carb gave out at around 11,000 rpm as the motor started to lean out towards 14-1 AFR's, and started mis-firing. It pulled over 54 mph in 4th gear, this motor has the full big bear trans swap and the 02-06 big bear front diff swap so I have electronic 2x4/4x4 modes, which means its capable of 65+ in 5th.
Which after trail riding it the deeper 1st gear is very welcome for tight technical terrain, it makes the rough terrain easier to deal with, and with the extend RPM's it still pulls faster the the stock trans by 2 or 3 mph in the same gear. It has so much power its honestly like riding a 450 sport quad, in 3rd out on the trails just mildly rolling into it blows the hides off and full corner power slides are epic and easy, 4th pulls way harder than it used too, and beats 5th for outright speed, lol. 5th gear is so long but still pulls hard, and honestly cruising at 30-45 mph the motor is so much happier with the lower rpm.
The dyno graph images may not load today as Photobuckets is down so check back to see!!!
