check out the new crank!

 

Does it slice and dice too? j/k.

Very nice.

 

They should make a horror movie out of this photo...

"Attack of the killer crankshafts" or something...

 

This is the roughed out crankshaft from the Evo8. There still is a fair amount of work that has to be done to it. So far the modifications have shed 3.5 lbs from the entire crank!

 

3.5 pounds is alot of weight off the crank! good buy

 

dont think they bought it, probably more like they are cutting away at some of the counterweight of the crank

 

No, that began as a stock crank

 

Nice work ! BTW - Ferrarokid built my last motor which has already 3,000 hard - HARD miles on it !!! he did a world class job ! If you want the best possible engine work consider him for the job!

Hurry up and get that engine built and ready to run !

 

We are also removing some weight of the exeddy flywheel .. the new piston/ rod combo is about 60 grams per cylinder lighter .. so this thing should rev pretty good .. Al, thanks for the positive input ! ! should be running soon .. waiting for the manifolds / turbo to arrive ! ! trying to decide what intercooler im going to run ! ! it all takes time ! !

 

yeah, i was there today at the Dark Horse shop, in Madison, NJ.... these guys really know their stuff....nice job guys....see u guys on the 30th!!!!

 

How are you going to get the balance correct? I understand the knife edge will reduce the drag as the crank swings throught the oil but I thought the reason the weight was there was to balance the reciprocating mass. Are you taking off an equivalent amount on the rods/pistons?

 

The crank balances out just fine. A four cylinder crank has it's throws 180 apart, so by taking an equal amount off of each counterweight the balance does not get upset. All it needed was some fine tuning on our balancer after the modification to zero the crank out in both kinetic and dynamic planes.

 

I remember seeing pictures of balance jobs where the machinist bolts calibrated weights to each crank throw to simulate the weight of the rod & pistons. Then they balance the entire assembly. Sounds like you are balancing the crank alone, but maybe I am misunderstanding.

 

Holy ****... Leathal weapon 5! Good luck tom...

BTW: He knows his ****! My clutch works great thanks to him!

 

That is a good and honest question, and not to be disprespectful in any respect, but inline engines do not require bobweights to be installed in order to get them to balance out. An example of a crankshaft that would need bobweights installed (Probably what you remember seeing) would be a small or big block crank from a V-8 motor. This crank gets balanced on its own, and the rods and pistons separately.
