When the Sprint Cars Notables Take Note of Our XTS Belt Drive

We can’t think of a single thing that makes us happier than having an engine builder tell us how much they like one of our products — and that holds true for every racing item we manufacture here at CV Products.

Take our XTS belt drive for sprint cars, for example. We know it’s a great system and apparently, so do our customers. A proven race winner, our belt drive features a two-piece design aluminum hard-anodized cam gear that not only eases, but also reduces the time to degree the camshaft.

Charlie Fisher of Fisher Racing Engines in Plain City, Ohio, is a big fan of our XTS product, but he admits had some doubts about using our belt on his sprint car engines. He said the camshaft drive systems in sprint cars are often subject to additional loads from the oil pump, magneto, power-steering pump and the fuel pump.

Nevertheless, he banked on obtaining more power and dependability and went ahead and pulled the trigger on running our XTS belt drive system.

But let’s let Fisher describe his experience:

“I immediately noticed during dyno testing that our detonation light does not come on when the engine is properly fueled and timed. Before this, it would come on two times during a run. I am seeing 0.1- to 1-horsepower per cylinder again when using the belt drive in conjunction with the crank trigger. Often we see a loss of top end power with a crank trigger due to lack of retard.”

Available in an XTS90306 standard cam and XTS90300 .391 raised cam blocks, these belt drives offer a patented friction-reducing roller thrust bearing that completely does away with cam thrust setup.

The back cover takes advantage of a continuous O-ring cord that seals the timing cover back plate to the block. The low-backlash belt dampens vibrations and harmful frequencies from the valvetrain, withstanding temperatures of 300-degrees Fahrenheit — and more.

And each and every one of our belt drives feature an integrated crank trigger complete with rare earth trigger magnets that don’t lose strength at higher temps.

“In brief,” Fisher concluded, “the system is easy to install, set cam timing, makes power, reduces harmonics and is priced right.”

It’s comments like these that keep us on our game, cranking out what we think is some of the best race equipment on the planet.
