gjm 3258 Report post Posted November 4, 2015 I didn't see any numbers, but the curves on the screen are impressive. I have seen a lot about Robert Karlsson's M10-powered E21 (940+ whp) so I've no reason to doubt the figures. Quote Share this post Link to post Share on other sites

CamB 48 Report post Posted November 5, 2015 Pretty cool - hadn't seen that yet. He's developed roller rockers for them, and cam profiles to take advantage of it. http://www.bmw2002faq.com/topic/133673-new-cnc-machined-roller-rockerarm-for-m10m30-by-dynotechse/?view=findpost&p=960883 http://www.bmw2002faq.com/topic/163327-roller-rockers-for-m10/#entry1031813 1 Quote Share this post Link to post Share on other sites

He can manufacture roller solutions for most cam/rocker-equipped engines. The M10 solution is still being prepared for market. There is a guy in Oz - Rama @ RHD Engineering - who has developed a kit for the M20. I'm unsure how effective that will be given the variable ratio rockers the M20 (and M30) use, but it seems to work. I know Robert has had similar design concerns for the M10 which he has ironed out.
