i know what the advantages are... but i've have been told many things about disadvantages, some say none, others say it weakens it. some people even say it will mess up the harmonics of a honda engine....

anyways, i have a basically daily driven 97 Prelude that is about to have a turbo setup from hell. i wanted to lighten the crankshaft to reduce turbo lag. i already have a lightweight flywheel, but i figured being able to rev it even faster shouldn't hurt.

regardless, what do you guys think??? does anyone have it done to street application, specifically to an H22. have you had any problems. people without the H22, please remeber that it has a cap bridge that includes ALL main caps and that knife-edging usually include re-balancing

There is only 1 reason to knife edge a crank, and it's so that the crank can cut through the oil in the pan.

Since honda cranks don't cut through the oil in the pan, there really isn't a reason to do this.

If you're just drag racing, and you want the lightest rotating mass possible, then knife edging may be for you. BUT, it doesn't really do much for the daily driver, and the expenses involved don't outweigh the benefits.

If you do anything, just have it balanced as a rotating assembly.

HTH.
