9A camshafts in KR

Hello. The question today is: what difference will make it, if I replace my KR cams with 9A cams?

 

 

Thanks!

Prob have a negative effect on performance tbh. The usual swap is to put Kr cams in a 9a head, as the Kr cams have higher lift + duration (iirc)

if you've ever seen comparable torque plots I'd say you'll gain a bit on mpg, particularly if you drive round town a lot, much flatter torque curve from the flat 9A intake cam.

much lower power band and alot flatter.

 

9a cam inlet cam 8.9mm lift

Kr Inlet cam 9.6mm lift
