thanks.. dd..

you can use it for a street engine.

It really helps at higher RPMs like 10,000 RPM since it is more aerodynamic.

Boyz...I just spent the last two hours creating a post on the intricate machining of doing a knife edge, only to have the internet crash as I was proof reading, sorry I'm F***ed off and over it!

Here is my crankshaft.






Try use a crankshaft that has fewer (drilled) sections removed from the counterweight lobes. These create some drag/resistance along the knifed edge which won't help with the knife edge effect.

Also, try getting a hold of a scalloped A14 crankshaft (assuming your K-edging an A14 crank)these are lighter already and may save on costs. The counterweight Lobe is also located further out making it easier to work on.

This is going into my street ute... haha.

Aside from making all the counterweights as much the same as possible, do you have any other tips for someone who plans to embark on this challenge Gary?
I have most of the bits to build a turbo A14, and I'm now leaning towards knife edging the crankshaft. (I've got a bet with a mate who is also building one, and I want an edge over him)

this kind of modification applies only for race purposes or can it be used for daily driven too???

any advantage or disadvantage of doing this kind of mod??

thanx..

This is my new crank(A15) i'l be trying out soon. You can also see the balancing. Milled and knife Edged.

LOL..glad to hear u're using engine mount to support it.. reading my question again making me laugh..haha

thanks lemonhead..

Nah Morgan it's a vee belt drive head, it's the biggest single phase unit I could get, variable speed would have been nice, very happy though. I've bought a whole bunch of other gear as well.

bituten, in Australia we use engine mounts to support our engines, not oil pumps, lol.
(sorry mate, it's just my bizarre way of literally reading your post, no you do not need any mods to an oil pump )
