Sounds like some good thoughts, What about roller rockers, they would redice the friction between rocker arms and the cam, why doesnt someone make them? And isnt there a certain amount of power being lost, going from the front sprocket to the rear sprocket, since the power is only being delivered on one side (in this case rappies left side) Therefore pulling on the axle forward on the left side creating a certain amount of friction betweenthe swing arm and the axle. Now I have no way to offer a solution to the swingarm thing, and no one does, just a thought.


Never thought about the goldball thing, sounds interesting.

 

I myself wondered why no one is making roller rockers for the raptor. Just one thing... those rollers will be real small judging form the OEM rockers. They might not be that difficult to make. It’s not a complicated thing.

 

All this is over increasing fuel and airflow and the mixing of both.,
Why not experiment with (TORNADO) intake designs, like those
that were on TV infomercials for cars. it makes the air spin faster,
through the carb ,therefore mixing air/fuel more effieciantly, hence, better
combustion and exhaust and more POWER.
The theory is sound, and it would be a He!! of a lot cheaper
and faster than taking your whole top end apart drilling and grinding
on things.
At least that's what I would start with.

tried the tornado on my 03 neon. did not do a thing
i want my money back!!!!!!!!!!!!!

 

We also have some local stuff here that is supposed to spin the air and create better HP and save fuel. I had two fitted to my car and it might save a little fuel, but for power, I have not noticed anything. I am thinking of trying them on the Raptor and ill give you feedback about it.

Here is the local web site I got the stuff from. It's about $20 each.

First of all......damb good thinking!!!
Second.....how would you put the dimples on the side of the piston? I work as a mechanic and we "pein" things all the time. By "piening" I mean to put small dimples all over an item to make them fit better. IE a bearing race outer side. Depending on the method of putting dimples on the outer side of the piston you can actually increase the size of the piston and as soon as your engine warms up.....WAMO. your locked up. ????????????

 

I was thinking that the dimples should not be little pumps on the outside of the piston, but rather little small dents in the outer surface of the piston. When the motor warms up, it will not add anything to the size of the piston and the outer diameter will still be the same. IE the dimples will be pointing away form the cylinder wall. I also thought about how the he11 you get it on in the 1st place. I was thinking that you mould a piston with big dimples on the outside. It must be larger than the actual piston size. Then you put the piston on a lathe and you cut it down to size, reducing the dimples size, but the finished product will have the right outer diameter, but still with very small dimples left after the machine work. I hope you get what I mean here. Then another way... and more time consuming will be to us a small grinder with a very small stone to cut very small dimples into the piston sides. If you can get a programmable machine (PLC) to do that for you that would be great

Maybe someone have another idea.

 

Hi ThrashAndCrashUntilItsTrash.

I gave your idea about getting little bumps on the outside a thought. (If I understood you right). It might work. The little bumps will also reduce surface area and reduce friction. We might have a problem with the bumps, maybe not. The idea I have with the little dimples is that they will act like little buckets that trap oil on the side of the piston. If it will work, who knows? The little pump idea will not help to trap the oil, but the smooth surface of a normal piston also don’t trap oil. If you can make the little bumps out of some sort of ceramic that will have less friction and maybe harder wearing that the piston material, it might also work great. These little pumps can my extremely small, so long as they reduce friction. You will have to make the piston outer diameter a bit smaller, so when it expands under heat that it fits properly inside the sleeve… with the bumps on the surface.
