Bonjour is all.

Here is a small info, on a scale 1/5 th prototype has 4 time engine.

The 12/13 next June, I organized a 24 hours endurance race has Besançon France (1 hour of Switzerland) and I committed a Honda GX 35 cc engine a prototype.

I'll demonstrate that time 4 engine and very suitable for endurance racing!

I post soon a few photographs of this prototype named RS67 4-stroke Engine.

I'm running a Honda 4 stroke engine in a dirt oval car, it's a bit like a dirt late model

Bonjours,

My post is not relevant to many people, it is true that it is 1/5thof model.

Me is mainly to demonstrate is that we can achieve with a block Honda GX35!

what Id like to know is how much bigger the gears need to be to get the same speed out of the 4 stroke compared to the 2 stroke??? The 2 stroke being some much lighter and being able to lay the engine down in the chassis for better centre of gravity, how did the penduluming effect the body roll through corners??? Did the more fuel efficient 4 stroke have better serviceing intervals in the way of pit stops for refuelling?? was this a benefit in making up time over the higher revving 2 stoke that consumed more fuel? was it more brutal on the gears or less brutal? I would be interested in seeing your pros and cons list for going this way. Jay C

Hello my brothers,
I apologize I have not seen your discution!
The 2 motemps time will always be more powerful than 4-stroke engine.
But after five years of endurance racing 24 hours, I got a good performance, 24 hours of Besançon 2015 rrive 2nd place behind a 2-stroke engine ........
