ATPT Dyno #'s
#1
I was thinking this would be a cool thing to do now that the races are over. Dont be shy about the results, all was equal. the thing i am thinking is maybe give a basic of what you ran IE: Samcoe 720 with ported head, MBRP race pipe, cams, 12:1 piston, on Alchy Dyno numer was 85 HP and 91 Ft lbs LMAO just kidden i know that motor would be lower than that but seriously, what a great way to share results from mods. That way there are more and more fast rides out there, thats what makes it fun is having some competition, not to mention helping the builders out that did the quads. If you just have to keep your mods to yourself then just say confidential but give your numbers atleast.

I saw a few dyno's. Adamsbad650 dynoed 45hp with a ctraptor 686 with 12-1 and mega cycle cam. He had nos but do not know if he dynoed with nos. I do not think the Bom dynoed any of his. Dunedevil was dyoning over 70 on his DS650. I am sure others will fill in.

My bike is stock internals with the Ct pipe, jetting, and Alba cdi. With the stock airfilter and lid on. I dynoed 39.4hp and 33.9ft./lbs torque. With the bike running extremely rich according to the sniffer on the dyno. I was hoping to get to redyno my bike after a few hints from Mr. Horsepower and Buttfungus. But the bike said no. When I get it fixed I'm planning on redynoing at HighLifter in Shreveport, La.

MBRP full race, 45mm, RWR cdi, K&N clamp-on= 40.7hp and 36.4ft/lbs running alittle rich up top and way lean down low(lean from 3500rpm to 5000rpm). Temp was pretty hot outside and very humid. DA 2867. Rejetted from147.5 to 145 and activated the accel pump(nozzel #50) and went back(temp even hotter. DA3300)= 40.5hp and 36.4ft/lbs. A/F MUCH better(no lean spot down low, slightly leaner than before up top). Given the same conditions as the run before(almost 4 hrs before), it may have run 41 something. That accel pump really woke up the bottom end. At 3500 rpm it gain'd almost 10hp and 10ft/lbs(the dyno operator pinned the throttle around 3400). by 4100 rpm all was the same. So if you are trail riding and putting around at 3500 or below and pinnit, you WILL smile!!! Still have some fine tuning to do, but the mods are fixing to start...

As mark says, I got 45hp off of my mild 686. It's a gas 12-1 with hotcams, not megacycle. stock carbs, etc. I did not dyno on nitrous. Oh yeah, and 41lbs of torque. I am a bit lean and have a terrible bog, I have to play around and try to get that bog out of there.
