I'm considering a cam on my Mini. I know this could turn into an absolute **** storm, but I am looking for cam dyno's, and specifically dyno's comparing the SAME car BEFORE and AFTER the installation of the camshaft.

Anyone care to share theres?

 

due to the cost of a tune and the level at which someone starts putting cam's in there cars there are very few people that will have direct before and after for cam shafts.

Plus, with the general way cam shafts work in altering how the engine actually breathes, it really does depend on other mods, although there are some general trends.

Cams that target low end should be paired with stepped headers, cams with top end (high overlap) should be pared with long tubes to shift powerband up. etc etc.

so what I am saying is, comparing a car with mods A, B, and C and adding a cam could be a massive difference from a car with mods D, E, and F with the exact same cam.

That being said,
Talk to a few vendors, do a bit of reading, browse the dyno sticky at the top of this forum.

I know I would never pay for a re-tune just after a cam, but then again, I change lots of things :3

If I am doing a radical enough cam, I usually am doing a lot of other stuff with it
So the tune really will not show each part individually, but the system as a whole.
