THE BUTCHER CRANK
This was once only available as an option for those that ordered a shortblock or longblock from us. Now, if you can provide us a good core, we can do the same magic for you to install in your own block. The Butcher process is standard procedure in every full boogie motor we build. If you want to be competitive, this is where it starts.
Knife-edging a crank has been around for years and normally involves a standard procedure to classify as such. Well, being of the different sort, and always looking for improvement, ours is of a slightly different design. Instead of the leading edge of the crank being cut and the trailing edge left alone, we knife-edge the trailing edge and round the leading edge. Much like the shape of an aircraft's airfoil. The result is a smoother "cutting" crank through the oil without the turbulence and parasitic drag that "normal" knife-edged cranks can and will give you.
Here you can see the leading edge of the crank. A nice machined, and smooth rounded edge leading up to a slight point. This will glide through that oil faster than Lydia during oil wrestling night at the Pip.
7 and 7s?
Yep...we can even butcher the 7 bolt 2.0 and stroker cranks as well. You know everyone just loves the shear anxiety behind using them. Let your crank do the walking and sign up here. By the time we're through shoveling the Dexatrim down their throats, they'll tip the scales at a lean 29 pounds. In pure, non-diet doughboy form, they weigh in at 35 pounds.
A Butcher in your EVO?
Of course...we can do it! The EVO cranks in stock form are rather lightweight to begin with, but we don't let that stop us. We're able to induce vomiting and puke out another 3.5 pounds. Weight after butchering...a mere 26.5 pounds!
STROKER 6 BOLT CRANKS?
Sure we can Butcher them...the muscle of all muscle...
As if that was not enough, and feeling a little sassy, we can lighten the 6 bolt crank by an incredible 7-8 pounds which results in even quicker revs and increased horsepower by eliminating that extra rotating weight. Now, I know what you're thinking but don't sweat it...our lightening procedure does NOT hinder its reliability nor its function. In other words, GO POUND ON IT! Couple that with an aluminum flywheel and rods, and you're talking about a motor that will rev as quickly as a crotch rocket.
Lastly, each crank is then fully balanced for race operation. We're talking around .1 ounce/inches of tolerance when we balance these Butchers. To put that into perspective, "RACE" tolerance is .2 ounce/inches (the industry standard) set by Stewart-Warner Engineering. "STREET" tolerance is .5 ounce/inches. What does all this jargon mean for you? By the time we're through with playing spin doctor, you will be able to safely spin these cranks up to 15000 RPMs. Can you handle it??

WHAT ELSE IS UP OUR SLEEVES???
We don't limit ourselves to just Butcher-izing DSM cranks. No sir-ee. Practically any 4 banger crank, such as the Honda B16/18, Nissan SR20, Volkswagen, Toyota 22R, select Bimmers, or whatever 4 cylinder crankie you can pitch to us, we can do it. For example...
NISSAN SR20 BUTCHER
SR20 owners rejoice! Experience the ultimate unique edge over your competition. This heavy Fat Albert tipped the scales at 41 pounds. Grabbing the cutter tools, we got him down to 33. An incredibly brute crank!
MITSU MIVEC 1.6 BUTCHER
Pictured here is a crank from the MIVEC Mirage...the 4g92 powered cyborg car from Japan. This little brute, the lightest crank we've done so far, weighed in at a lean and mean 26.5 pounds before surgery. After facing the Butcher, a mere 21.5 pounds was achieved...not to mention copious amounts of reduced parasitic drag.
