Luckily for us critters, the OEM engineers designing our chosen brand of UTV deliver what, in most cases, are stellar calibrations for the common driver piloting their rigs through average conditions while driving bone stock machines. We all owe them our sincerest gratitude for furthering our chosen sport – the ever-growing UTV craze. However, once a bit more power is added the raw output of our steed via hard parts (exhaust, intake, tuning), or an alternate tire is installed, or a UTV accrues miles on its platform, that wee-little drive belt struggles to keep up with the increased demand. This is when belt slippage occurs, power delivered to the ground begins to fade, and acceleration notably decreases.
The Continuously Variable Transmission(CVT) is notorious for high amounts of parasitic loss through the shift range, and further optimization is possible by employing the proper components.
Loading a UTV onto a Dyno and making a few pulls to characterize a WOT power curve is a tiny fraction of the true battle in developing a well-tuned engine calibration or clutch setup. Part throttle cruise RPM Ratio, upshift rate, response to load changes (backshift), side force, and many other factors contribute to that bottom line we’re all interested in….WEIGHT….Nope; hang on! – That’s part of a different article…. Those factors contribute to – SPEED! ACCELERATION! That throw-you-back-into-the-back-of-your-seat feeling, and that beat your buddies to the finish line thrill we live for. If you have a worn out clutch setup, you won’t be standing atop that podium. Or, if your wildly tuned engine makes 20 more ponies than the fellas lined up next to you and your tires have the best traction of all, but your clutching calibration can’t put it to the ground – then you’ll likely be watching taillights ahead of you going into the first turn at the big race.
Much like how the PowerVision CX can tune the engine of your UTV exposing its fullest potential, a Dynojet clutch kit will transfer that power to the wheels with the utmost efficiency allowing you to pull ahead of the competition. Utilizing the state of the art PowerCore Software and the renowned Dynojet 224xLC Dynamometer, we’ve crossed all of the T’s so that all of the I’s in your clutching setup remain dotted with the utmost precision. Heck, we’ve even built a nifty tool to measure physical sheave travel of both clutches and built a testing matrix to itemize what the smallest of change produces for an end result.
Not only does the Dynojet Dyno enable us to simulate all of the varied loading scenarios to expedite development and measure the raw acceleration or power output, but each calibration is field tested over and over to verify the maximum reliability and performance is delivered to you. If we can’t accelerate from one marker to the next in a lesser time than the prior setup, then it’s not good enough for us, and we return to the lab.
REGARDLESS OF THE TERRAIN YOU’RE GOING TO TRAVERSE THROUGH ON A GIVEN DAY, OR THE ELEVATION AT WHICH YOU’LL BE DRIVING, DYNOJET INSISTS ON EQUIPPING ITS CUSTOMERS WITH THE RIGHT TOOL FOR THE JOB.
Ripping up the dunes with monster paddle tires loads a rig far differently than the same machine moseying along a rocky plain during a family outing, and clutches will respond differently due to those vastly varied conditions. Thus, we won’t supply you with just one possible calibration set – but ALL of them – and we’ll instruct you which components to change to fit where you’re headed or even match the tires you’re installing.
