Comp Cams (R) has taken camshaft technology for open wheel Modified racers into the next century with the introduction of its T/C Camshaft line. The series is comprised of 10 new cam designs in four categories available for mechanical flat-tappet and solid-roller applications.

Comp's engineers set out to design a camshaft specifically for the requirements of open wheel Modified racers. To accomplish this they had to take into consideration the tire restrictions, chassis technology, engine combinations, and common rules packages found in open wheel Modified racing, such as IMCA.

By marrying existing technology with some of the newest, most innovative lobe designs, they produced a package that delivers an extremely wide powerband, pulling hard off the corner and all the way down the straightaway. This design also minimizes tire spin, effectively creating legal traction control. These camshafts have been extensively track tested and proven faster than any camshaft Comp has ever tested for this type of racing.

Of all the cams in the new T/C Series, the 287CRL R7 and 291CRL R7 are the most intriguing for more than one reason. This is actually a roller cam, but it looks like a flat tappet. And it makes more power than a true flat tappet. But just how did Comp achieve that? Simply put, the CRLs use the same top-end valvetrain as a flat-tappet cam, so the difference is below the manifold.

As the chart below shows, the T/C Series offers a cam for just about every open wheel Modified racer.

The newest lobe designs and a nice broad torque curve with great power and little to no tire spin-what open wheel Modified racer wouldn't want to try out this legal traction control?
