No hp numbers or graphs but they may actually have grown the engine big enough to start using the big ports in the M-8 heads.

Nikasil       

Not the right application for that stuff.

I bet Randy Torgeson can make some nice iron cylinders for this. That would be the route I'd prefer.

Is Nikasil really the problem or was it the butchers selling it? As an F1 fan, I don't have a ton of respect for NASCAR, but I'm sure this guys knows more than the infamous HD Nikasil guy.

Or was it the aluminum cylinders with no sleeves? I don't know.
Nikasil left a bad taste in a lot of mouths but this was not limited to Harley. BMW and Porsche had bad spells with it too. That said many use it today successfully.

So the p3R flywheels aren't a proprietary item then?

Neat stuff

Just by "looking" at those cyls., it seems hard to believe that they will cool "better".

Same thought. Those fins are about as useless as you can get.

Nikasil coated on steel sleeve? Does that not negate the positive of transferring heat directly through the aluminum? Nikasil is a great product but some plating processes leave a lot to be desired and knowledge on finishing Nikasil. I would think the steel sleeve would have to coated and then pressed into the cylinder due to the chemical used to plate the steel would harm the aluminum.

Knowledge on Nikasil good read great guy.

Are these discussions about liquid cooled cylinders? If not, it may not be relative to the HD stuff. Liquid cooling is a game chager with cylinder expansion control etc..

Yes i agree but found the finishing process very interesting. Since the topic of failure  came up i thought i would share this info. Honing a Nikasil cylinder is honing a Nikasil cylinder.  Read if you like or not.

The article is interesting. Ring seal, piston and ring life, and oil control are all critical.
Baby with the bath water as far as Nikasil in my opinion. Lets wait and see how these motors hold then decide. This guy obviously brings a new set of eyes and experience to the HD world and his approach is fresh. Give it a shot

The guy just about went out of business standing behind his work which in today's world is very admirable. I sent him a set of brand new cylinders from the factory before the motor was ever run to have him finish them better then OEM. Very interesting about how porous the finish is and cross hatching is the enemy.

Back to topic the steel cylinders liners coated baffles me? A lot better minds then me have a reason and i would like to hear the reasoning? Defiantly not to cut costs.

Please don't misinterpret my post. I do find the info very interesting and have been following the nik development. It would be interesting to know why there has been some successful use of nik cylinders on Harleys (although it seems minimal) and why some have been repeated failures.
