This is the road to the most powerful two stroke (relative to cc) ever. Aiming for 30+hp from 50cc.
Lofty goal!
Here's a few key points:
- 100% bore width single exhaust port, no bridges, non. This leads to unrivaled blowdown specific time area.
- What should be excellent transfer duct geometry, large radius on inner walls to minimize flow separation, constant side wall angles for control, large duct volume for gentle "delivery"
- Valveless tuned length intake with nitromethanol injection, aimed at the transfer inlets.
- Ridiculous crankcase volume, no piston pumping here, it's all about resonance!
- Tuned pipe, tuned crankcase, tuned intake, tuned everything, resonance!
To be able to run such an monstrosity of an exhaust port without instant catastrophic failure there's a special two-piece piston with a retained piston ring(thanks Mark Atkinson). It has no holes in the skirt either, no short circuiting between the transfers and the exhaust.
I've designed the whole thing from scratch.
3D printed, cast(lost PLA), and "Nikasil" plated the cylinder myself in my garage. Designed the case and pipe for it. I've received lots of help from the community with things I haven't been able to do myself(lack of machinery and/or skill)
Especially machining, until recently I didn't even own a lathe.
Thank you guys, you're the best!
I've designed and built a landspeed bike for the engine, plan is to set a new class record at Bonneville.
Thanks for following the adventure, and fear not, I've already got plans for the next project - Symmetric transfers, four exhaust ports, two rotary valves(but not where you think they'll be), forced induction, no need for expansion chamber(!) ++
Many years of two stroke madness up ahead!
Easy is not worth anything
