What makes a cam lumpy?

[ari666]

mines 110 when i ordered it the build was gonna go in a different direction.... nevermind.

Mines 113 but i dont have much overlap. Its smooth as silk. But my car's a hektic twin turbo emotec.

my cam is 113LSA
as said, LSA isn't the only determining factor of 'lumpiness'. Duration also plays a big part.

My 304 has a 'lope' to it's idle. But nothing over the top, as drive ability was a high priority for me. The quality of the engine tune also can determine the quality of the idle

You wouldn't want much overlap with turbo setup, is that right?

in the tune lol, when i had a 224/228 112 cam fitted it didnt have much lumpyness on idle so got the idle changed to make it more lumpy.

My LSA was 114 and it had a bit of burble and shake while idling in a M6 VX Monaro. For the new beast it'll be at least 112 or maybe even 110 cause it probably wont be a daily driver.

However, everyone is different and each to their own. It would be best to go to meets and listen to cam combos and try and scam a ride with them to help you decide.
