I’m in the process of putting together a dyno test program for aftermarket snowmobile drive belt performance comparison.
The concept is to take a stock sled, dyno at crankshaft like we usually do, then install drive clutch and driven clutch, slide the sled forward on my dyno table, connect dyno drive shaft to custom sled jackshaft that will allow jackshaft to drive SuperFlow dyno driveshaft instead of chain to driveaxle. This will allow us to measure horsepower delivered to jackshaft/ drive axle at various engine/ vehicle speed with various drive belts.
I need to “rent” stock engine sleds to do this testing if possible.
In exchange for one or two days of of drive belt/ clutch testing, the sled owner will get a day of whatever dyno testing he would like to do, value 8 hrs x $125 = $1000. Or we can work out less dyno time and cash to boot. And there will be drive belts (the ones that work better than OEM) to go to the sled owner. Engine/ sled safety will be gauranteed by DTR/ belt manufacturer.
The first sled I need for this is a bone stock (other than timing/ fuel tuning that we can temporarily put back to stock) 03/ 04 Firecat F7. Then I need to line up a dozen other performance sleds for similar testing, I will post a detailed list next week. If you are nearby, have a F7 EFI stocker we can use, please Email me at info@dynotechresearch.com.
