Exhaust valves on a two stroke.

This is where KIVA software simulations would help, Los Alamos.

Honda made a 16,000 rpm 4 stroke in the early 1960's

With itty bitty valves to match the tiny bore and stroke. Not the same problem as a 450cc cylinder like the 3.6 V8 under discussion. But certainly a Formula 1 or MotoGP budget could get it done.

Hi - FMP, thats beyond my skill level. If I give you all parameters, can you produce a simulation for me?

If you and your partner are considering this, contact them and inquire as an option.

Pete, Just say it like it is .. FUMpY like all your posts, that makes no sense what-so-ever ..

Power valves that lower the exhaust port are one thing. A supercharged two stroke needs a positive stop type valve ..

I had a look at it in Maranello, they just needed some ficht technology but a little too soon for that

How'd they hold the heads on?

Do you have any more information on this engine?

2 pistons per bore..... staggered crank/ port timing........huffed......you can boost then........
