Andrew FrankelHOST
There are lots of cars out there which don't manage that.
Jez MedingerGUEST
Um, I've, I've a brilliant 2CV fact, if, if I can share it, and that is that in 1978, the 652 cc 2CV engine got Nikasil-coated bores.
Jez MedingerGUEST
And this is interesting.
Andrew FrankelHOST
Oh, like a Ferrari.
Brandon ClarkGUEST
I say similar in they install a complete replacement cylinder, but even then, most of those are open deck at the top, and so you still haven't addressed the main flaw of the design that Porsche moved away from in 2009, which is the unsupported top and bottom of the cylinders.
Brandon ClarkGUEST
Then moving from there, it comes down to the material itself and why Nikasil is so much better than ductile iron.
Brandon ClarkGUEST
First and foremost, it's much, much harder, about two to three times harder than ductile iron, and so much less susceptible to scoring and to additional wear over time.
Brandon ClarkGUEST
Because we do a aluminum replacement cylinder that's nicosil coated, we don't have any thermal expansion issues.
