Default Re: hmmm...it might be a buzz box...but the new AMG A-class takes a 2L into our terri

Did I need to say "on pump gas" and "with 500 cc per cyl" or did I need to go into combustion chamber design and flame front propagation?

Or shall we talk about how the undersquare design reduces flame travel ? Could not find mention in a quick look but suspect the rods are long for a 2 liter 4.

Certainly for a 50cc engine at 14,000 rpm 200 hp/liter is easy, can even do it with a carb, meaningful torque is harder but the -45 is only turning 6,700 rpm (suspect 400 bhp might need 7,500).
