In the realm of speed parts we aspire to own, a Winberg crankshaft is right up there. If you are using one of these arms in your engine, changes are there’s big boy power being produced. Winberg rolled out their unique and self-developed WINfinish polished cranks a little while back but this is the first time we have checked them out in person. Luckily for us, we already knew of the process and didn’t look like half the people walking up and telling the Winberg people that they liked looking at the chromed crankshaft! We saw the Winberg guys shiver a time or two when someone said that.
The WINfinish process involves an additional eight hours of labor on each crank that is enhanced with it. It is an 8-step mircopolishing process that is 100% mechanical. There is no chemical etching of the crank like other companies use. According to the guys at Winberg, this is a superior process because it leaves a finer finish than any known process developed to this point.
So far, the technology has been a big hit with, NASCAR racers, Pro Stock racers and the Competition Eliminator crowd is jumping on board strongly as well. Interestingly, the nitro burning teams have begun to buy the cranks as well, and it is saving them money. The teams are able to get 20 to 30 more laps out of a crank that has the WINfinish because the process perfects the fillet radii, the area most prone to cracking in a ground pounding blown nitro engine. Obviously the finish helps oil shedding, the associated drag, and it decreases oil foaming.
To the touch, the finish is surreal. It feels like the crank is actually made of glass. Scroll down to see some true high horsepower bling!
Is it the lighting, or do these have the appearance of a dark chrome? Is the polishing process similar to the micronite process?
Man… that sure is purdy.
I’d have to put a clear oil pan on my car if I was running one of those.
eight thousand dollars for a crank ..no wonder DG drive a 500 dollar truck
that piece looks to be chromed. but i know its not!!
I would like to see a dyno test with the only change being a regular forged crank and one of these. I would like to see the difference in power & torque. Also if oil temperature and pressure are affected and possibly how quickly the engine will rev.
