no HD built a 110 drop on kit as well.. again these are tool steel liners. just because its thin is like comparing a watermelon to a peanut. and again steel liners are being used in the automotive side today and have been for over 18 years in V-8 chevy LS engine , millions and millions of them in production.
Chevy doesn't have a spigot. The liner is completely inside the block. I'm not saying an opinion one way or the other. Just that the comparison isn't a direct one. I read on the internet that the spigot has no load on it, but why did the HD older 113 kits crack right where the spigot started?
Tool steal or whatever it is? Is that harder and more brittle than ductile or cast iron? I don't know, and I am asking.
It is tougher and less brittle than cast iron.
Right from HD's propaganda machine.
I agree with all of you.
1.) I understand that steel liners have been used successfully in the automotive industry for years.
2.) Steel liners in a liquid cooled aluminum block are vastly different than what we are talking about here.
3.) Steel is stronger and less brittle than cast or ductile iron.
4.) Steel (in general) has a higher heat conductivity coefficient than iron.
I am a mechanical engineer by profession and I can’t help but keep coming back to heat transfer issue by taking a casting designed for a 4” bore, boring it out to 4.125” for the pistons, and then boring to 4.185” for the liners. There cannot be much cast iron left and what happens with the additional heat from a more voluminous combustion?
Since the 103ci to 110ci kit appears to be a scaled up version for the 110ci to 117ci kit (steel liners and all) and the 110ci kit was out a little sooner, maybe we should look to 103ci owners (and upgraders) for emerging problems.
