I went to a ski-doo shop yesterday (AERO PA in elgin IL) to buy a few parts... i was asking about local dynos to find one of the mechanics there takes his banshee to freeport il Honda. (i guess its about 50 an hour) he said i would probably have to find some flat track tires or burn down my ohtsus to get a proper reading.

i was thinking of getting new tires anyway (some 22 inch tires) so i guess i could do that (although the traction on the ohtsus is great...)

let me know if you guys have suggestions. (anyone care to explain the process of dynoing a quad? ive seen vids of it done before, but dont know exactly all of what is involved)

Thanks guys

 

You can use your ohtsus but your numbers will be lower. flat traks give a truer reading because all the rubber is hitting the dyno drums and the knobbies give alittle under load. (that how it was explained to me) Keep in mind everything can change a dyno reading. Besides temp and humdity outside if you change; air pressure, tire size, tire type or gearing your number should be different. Also remember that every dyno is different and will give different readings. I know we all want to know our numbers but unless you are fine tuning or going to do mods and want to see the power difference don't waste your time or money. If you are going to do mods remember use the same tires, gearing and the same dyno when comparing numbers.

 

Hey Roost,

Where is this dyno you found? Im not far from Elgin,and I would like to get mine done also. If you get a number, please let me know. I know there are alot of dyno'sn around here that run street bikes, but they only have one drum, and you cant get an accurate reading like that. The only other alternative is using a car dyno, and that would just eat up a clutch in no time.

Thanks,

Gary

 

i got my banshee dyno'ed the other day they used my ITP tires and it was dyno'ed at 58.3, does that sound about right to you guys??

 

i guess the place is in Freeport illinois (freeport honda he said)
im from dekalb (nearly an hour from the aero PA store) ill have to search for the freeport honda and contact them (wouldnt mind going at the same time so i could compare results)

And i would say that is probably about right for your shee.... but then again i dont know what mods do what for a shee (just comparing it to what other people have claimed thier HP to be with similar mods) i was reading some back posts and i guess there was a difference of like 12 horsepower between two dynos.... (makes me wonder if its even worth the 50 bucks or whatever to do it... )
