Dynatek CDI And Coil For The Rhino
Dynatek Dyna FS Digital Ignition box, or CDI box, is one of the
hottest performance items you can buy for your Rhino. Yamaha limits
the engine RPM's on Rhino's to 7,700 rpm's. The factory does this
to protect the motor from being over revved, thereby causing
damage, particularly by inexperienced operators. It doesn't take
mush to peak this on a stock Rhino when zipping along at 45mph. For
many, the top speed of 45mph from a stock Rhino may suffice, but if
you are like me, at times you want a tad more.
Why We Like It:
CDI stands for Capacitive Discharge Ignition. The bottom line main
advantage of putting a aftermarket CDI on to go faster. The reason
is the aftermarket CDI allows your engine to reach a higher RPM
therefore higher performance and speed. Dynatek CDI's have a much
hotter spark energy and on those applications where it applies
there is no reverse gear rev limiter either. The Dynatek box
changes the entire timing curve and raises the rpm limiter from
8500 to 9000 rpm. The box does not add power to your vehicle per
se, it just allows you to use more of what's already there but
limited by the factory for protection of the motor and thus gives
better performance throughout the entire rpm range. The Dynatek
also eliminates the reverse rev limiter, and increases the spark
energy. This is a high performance CDI without sacrificing the
reliability of your Rhino After installing both products we found
that the Rhino started quickly and there was an instant distinction
in low and mid range power upon acceleration. There was more zip
and with the higher rev limiter our top speed was increased by
about 9-10 mph!
The Dynatek Rhino CDI will help you with this. It offers improved
timing curves, and a higher Rev limit (9000 rpm verses the stock
7,700rpm.) It'll makes your Rhino easier to start, give it improved
throttle response and increase the spark energy. Pretty much a plug
in module replacement, the mounting is super easy.
DynaTek also offers a Performance Coil kit that replaces the factory coil with a more powerful and efficient coil. When used in combination with their CDI box the duo will increase the Rhino's overall performance from low to upper range with a significant difference.
The bottom line:
This should be one of the first mods you do. Instant plug and play performance and I think for the money, about $210 for the Rhino, the Dynatek is the way to go. It had not of the start hesitation issues I've experienced with rival CDI units. The removal of the annoying stock reverse gear limiter is another big plus in my book. You will notice an instant change, with easier starts, better low and mid range acceleration and even some on top too. Who can beat that?
