Differences between century cylinders
Hi guys,
Have a look at those two cylinders. Ports are different. The one with the bigger ports could produce more power?

Re: Differences between century cylinders
Stelious you have to compare like for like, not a century with a silver century, I can't remember the figures now but there are probably more than 10 different cylinders for the century family.
Make it idiot proof and someone will make a better idiot.

Re: Differences between century cylinders
Sorry yes your right, there are 4 or 5 of those, I've only built one of those for racing & I made it a twin cab one. With the high inlet cylinder, where I felt the port time areas were more favorable.
A la Raoul Lealand who came up with the idea.

Re: Differences between century cylinders
Well you have started it Stelios, you have 2 different types of Century cylinder.
Picture taken from crankcase side, exhaust port at top.
Here is type 3
Anyone else got a different one?
This is Century not Century Plus, carb stub on the Starboard side.

A little.
I'm not going to give you any of my racing secrets & figures, if I did, I'd have to shoot you!
I don't have a gun, but the other Charles does.

Re: Differences between century cylinders
What for?
If it's for that 5R you will need an 8" pitch one, that has been pitched up, but the 5R should have a splined propshaft.

Re: Differences between century cylinders
I am just making some fun but in the back side of my mind I have a plan to tweak a silver century.
The 5R is not in the back side of my mind yet.
