Can you get knife edging done anywhere or is it like P&P that should be left for the pros like portflow or alaniz? There is a local shop that can do it for me for pretty cheap (friend). Just wondering what kind of things to look for, as in terms of a job well done. What types of questions should I ask shops before jumping into this?
How much does it cost normally?

 

I have not heard very good things about knife-edging a stock crank. Ask the machine shop about the downsides.... Other wise, most machine shops can perform this procedure well, unlike head porting, which is a very delicate process. I would ask about the strength of the crank after knife-edging.

 

knife edging shouldnt harm the crank at all since it is forged from the factory. just have it counter balanced and then knife edged and if you want your crank even stronger just have it shot pinged. one of the best machine shops is mesa balancing in miami.

 

Mesa's top notch... get all of my parts worked on there now.

305 884 5368 got their number on hand...

 

mesa balancing is super cheap compared to others and he does it to your extac specs.

 

my racecars crank is knifedged. if it is done right it will reduce reciprocating mass and slice through the airborne oil flying around in the crankcase at high rpms.it will not weaken the crank.l

 

Knife edging is pretty much worthless on a honda crank IMO, save for the minimal weight savings. Knife edging is carried over from the "dark ages" when cranks used to splash through the oil in the pan. In our hondas the crank doesnt so much as go near the oil supply, and most Bseries motors have windage shields from the factory to further prevent it.
If you have a full on race motor and want to cut the absolute last few grams of weight, then go for it. Otherwise i would seriously just look into a lightweight flywheel. Also keep in mind that you run the risk of weakening your crank, if you take it to a lesser shop. You'd be doing more harm than good.

 

i agree w/ rioninja, the only time I've thought i necessary is on a na full drag engine that gets rebuilt quite often to check for tolerances. Even a decent job won't carry too much risk towards structural strength but many times it doesn't inlude counter-weighting which is the entire point. If you don't care for counter-weight, take the whole thing out

 

I had it done on my race car, knife edged and balanced. Worked great but dunno if it had any difference cause I never compared it. Motor was a nine sec motor though...*Tisk im sorry its dead now R.I.P
