Hey Paddock,
I'm heading down that slippery slope (already started) and been looking for information/opinions on case and crankshaft modifications. I already had my case boat tailed and was looking to complete the task by having the crankshaft knife edged. Then I found this article from Neil at Performance Development. http://performancedevelopments.com/living-on-the-knife-edge/ Sounds like he's legit and I haven't done crankshaft mods yet. Thinking I should leave it be. (IMG:style_emoticons/default/beerchug.gif) Shane |

my favorite ....
So why knife edge Porsche crankshafts? I think the answer points to two main reasons. First, the assembler feels good. And second, the customer thinks he is getting something really racy. If you want to feel real racy without compromising your engine, put a number 1 on your door and a racing stripe down the middle of your car. It will be cheaper too. |

Neil seems to be respected in the Porsche community. As for knife edging a 911 crank, I suspect there are better places to drop your money. The counterweights on a 911 crank are nowhere near as thick and heavy compared to, say, a small block Chevy. I would think you'd have to be at the pointy end of engine development spend before that kind of mod would really make sense. Just my opinion ...
Edit - didn't actually read Neil's article until after I'd posted. He said it better than I can. |
