Oh I forgot - it has some mild tuning

and gets into top gear @136mph - enjoy Smile

Still sounds like a pissed off lawnmower though.

Which speed record did it beat?

Was that a light-gate speed averaged each way?

I was under the impression the Kreidler record was for an old-school flying mile which frankly, fucks a light-gate speed up the arse in my book.

Oops - mind you I've not been on much this past month as I'm doing a lot of building & decorating indoors. I came across it whilst researching world records for some stuff I'm doing next year.

Didn't realise that liner had a turbo on it as well? On a 50cc cylinder FFS! It looks bigger than the smart turbo that SOND is fitting to a 400! How it ever makes any positive boost pressure id like to know? I wonder what the power is on that engine, and how long it would hold together? You need to know what your doing with a 50cc to make 16bhp+ so i can't see a turbo being able to add that much more power surely?

Haven't checked out any details on the power output but I'd be surprised if it made less than 20hp. Getting 3x normally asphirated power is commonplace on bike turbo engines, but I think you need to be something special (and have a big pile of parts) to achieve that with a tiny turbo stroker.

My first turbo kit made 300hp and was boosting a bit to quick to be really comfortable as a roadbike (though the current owner (also a member here) loves it. That's a 100% increase. My own bike is 500hp-capable and has great road manners. Easier to ride off-boost and less of a mid-corner rush than the smaller setup. Also, I should think that adding 10hp to a 5hp engine is easier than adding 360hp to a 180hp one. The work that needs to go into turbocharging a zx12-r to 3x output is quite extensive.

I think it'd be very difficult to run an AM6 engine with a turbo still inside of an RS50 frame. They are very tight inside the frames and judging by that image it wouldn't fit in.

Geri you should make it your next project to turbo an RS50!

Pete. · Super Spammer Joined: 22 Aug 2006 Karma :

Or a R125 perhaps?

Yeah I suppose a RS 125 would work out better.

A 4T would take the turbo better I suppose?

Never thought about it. 2-stoke tuning is a bit of a dying art, at least with 4-strokes you can easily mess with the valve timing to reduce overlap. I wouldn't know where to start to do that with a 2-stroke. I gather there might possibly be a limit for reed-valve engines where boost pressure will hold the valve open, have to give that some thought.

Anyone know of a crashed r125 going cheap? I hear those minarelli engines are quite strong.
