What’s the difference between thumpr and Xtreme camshafts?

While the Xtreme Energy camshaft showed a reduction in vacuum generated, the Thumpr camshafts were slightly more reduced and under the 16 inches of vacuum recommended for engine driving power accessories such as power brakes where vacuum is critical to safe operation.

What kind of power does a thumpr have?

Both are Xtreme Energy grinds, the former measuring in at 224/232 degrees of duration at .050, and the latter with 232/240 degrees at .050. The wild card of the bunch was the 227/241-at-.050 Thumpr, which proved to be the best all-around performer in our 347.

Which is better thumpr Cam a or C?

Cam C proved to be the most potent of them all despite giving up 5 degrees of intake duration to Cam B, and .034- and .059-inch of lift on the intake and exhaust valves, respectively. In fact, the Thumpr produced more torque down low than the smallest cam in the test, in addition to posting the highest peak output of 466 hp at 6,300 rpm.

How much horsepower does a thumpr Cam have?

As expected, Cam B improved upon those figures dramatically, kicking out 464 hp at 6,200 rpm and 426 lb-ft of torque at 5,100 rpm. Longer-duration cams typically sacrifice low-end torque for top end power, and predictably, Cam A held an advantage of 5 to 10 lb-ft of torque from 3,600 to 4,200 rpm.
