I mean there is def. some bias in the article as he is interviewing dude from LA sleeve, but at least transworld does some decent articles from what I have read.
The thing that made me question it was when he spoke of the heat transfer to the sleeve. It one thing to say that, but you should back it up with facts to prove it imo. Perhaps the materials they are using in the sleeve actually have decent heat transfer #'s..... I dunno.
As for the F1 cars, well I mean they are limited in HP so power to weight ratio means every thing. Imagine how much weight 12 cylinder sleeves would add. Much more weight than they can find to shed off the cars no doubt so take it all for what its worth. And I'm just playing devils advocate here as well so don't shoot me.
I would love to see some power #'s of sleeved motors vs plated motors. I may try to run my 500 on a dyno the summer, but we'll see.
And you know, talk to 100 different people and you will get a 100 different stories. While I don't race or hold WOT for long periods of time I still ride it for what its worth.........well, for what I'm worth lol, so I think a sleeve will do just fine.
