It would be pretty scary if it did. The turbo cam has a higher lift but I guess (and I can only guess as I don't have a turbo cam to measure) that the rise of both cams are similar around this initial lift area <= Is that well explained?

Here's what I measured for a non-turbo cam



Also please note you are not measuring a 2mm rise on the cam - but a 2mm deflection of the valve - after the cam has pushed down onto the rocker on to the valve stem...

...I'm planning to get round to making a measurement of this valve stem movement and comparing with the cam measurements I've already made.
