Unorthodox Racing Crank Pulley VS Stock Crank Pulley (weight only)
 

I just got my unorthodox racing crank pulley from fellow the370z.com forum friend CJBinder. Thanks man!

I busted out my scale and the stock crank puley weighs 2146 grams.

The UR pulley weighs 460 grams.

Now if you want to compare apples to apples... The stock pulley weighs five apples (one half eatin) and 3 cans of beer (because I ran out of apples)

The Unorthodox Racing pulley weighs about two apples

Sweet, today I weighed a bottle of Coke & a can of Pepsi, which one could potentially ruin my engine?

So how different is your drive/application of power with the new pulley?

Yeah I will post the drive application later. I am going to have my mechanic put it on in about a month. I took that pulley I was taking pictures of off of a blown engine on a hoist and it was not fun... I do not want to try it with my engine in my car.

My car is supercharged so I am just thinking less parasitic loss... Hopefully it makes a noticeable difference since the supercharger is already creating parasitic loss. I am sure it is going to be hard to tell the difference. I put a lightened pulley on my scion TC and couldn't tell a difference.
