Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

The narrow LSA cam
immediately delivered the authoritative and extremely choppy idle we expected from it.


“The 104 LSA cam is going to exhibit some drivability
problems,” said Crane Cams Valve Train product manager,Chase Knight. “ Torque between 500-1200 rpm is going to suffer.”

The high amount of overlap in the 104 cam allows exhaust reversion at very low engine rpms. This dilutes the intake charge and contributes to poor slow speed torque and part throttle manners.

The anemic idle
vacuum also rules out the use of power brakes. “This would be a good cam for a manual transmission car or an automatic with a very high stall,” said Knight.

If you can stomach the extremely aggressive idle,lack of power brakes and have the proper driveline to take advantage of a tight LSA cam, it would make for a very peppy ride.


Also, spoiler alert. The 110 made the most HP. Not the 104 nor the 114.
