    M50 horse power.

    Ok so I got in to a argument with a guy about how much power an m50 single vanos motor has. Does any one have any runs that show how much Power a m50 has with no a/c, no power steering, no manual fan, single vanos, and headers.

          So true -- You got me all nastalgic...

          I wasn't at a dyno to be all "how much hp do I got and shiz" -- i was just trying to get my AFM right, Karl at Active Autowerks wanted a baseline in order to send me a few burns.

          all that to say, this was a healthy engine and didn't make that, lol....

              That's too rich after 3500 if those written AFR's are right haha - some power to be had if you lean it out a bit.

                    oh that car is long gone, just reliving my e36 days -- i did manage to get things squared by removing the AFPR and adding AA software though.

                    yeah, and i think the later versions a bit more. same was the case with this engine which was an M52 -- wasn't trying to hijack/derail this thread.
