Dyno page

Under construction more to come

Well Darcy and myself finally got around to do some dyno testing on my old RZ350 engine which is basically stock except for some mild porting, head cut, and stock carbs bored out to 28mm's. A little info. on the dyno: This is a engine dyno which Darcy has built himself and it spins up a large wheel of considerable mass. Darcy has fine tuned the software with the help of the designer and friends and it is quite accurate. The main use is for snowmoble R&D work so that the differences can be seen.  So how do you mount a motorcycle engine? Well I had an old RZ frame kicking around which I cut up and welded studs on the bottom so it would fit on the dyno frame. Darcy machined all the coupling pieces to work on the RZ flywheel. I will post some pics soon. First dyno test: We decided to use my old race engine first as a test run after some wiring issues with mismatched flywheels it fired up and we were up and running. I only had stock exhaust to try and we only tried a few combinations.Stock modified airbox versus K&N filters.The stock box lost about 4hp to the K&N's. TZR cdi unit which is what I used on the TZR/RZ against an RZ cdi. To our suprise the TZR box lost hp to the RZ cdi unit lesson learned. Our best result was 63hp running stock pipes which isn't to bad. Next dyno test Well we want to build a set of dyno pipes that can be reconfigured and adjusted so we can find out what works best. We have a combination of Jolly Moto, Swarbrick's and Darcy pipes to try. We will try them on the old engine first then its onto the new race engine for extensive testing. Stay tuned.
