Is the Billet Compressor Wheel vs the Cast Compressor Wheel Worth It.  The Billet Compressor Wheel is Usually Over 100 Dollars More than the Cast Compressor wheel, Which Leads You to the Question, is the Billet Compressor Wheel Worth It or is Your Money Best Spent Somewhere Else? I Made This Video To Help You Make an Educated Decision.

Some Billet Compressor Wheels Weigh Less than the Cast compressor Wheels and Some Billet Wheels Weigh More than the Cast Compressor Wheels. I Would not Make a Decision Based on the Weight Alone. I Would Chose Based on Usable Surface Area that the Blades Can Use the Capture More Air.  In this Video I also Demonstrate an Example of a Billet Compressor Wheel that I Didnt Think Was Worth It. The Main Advantage Of Billet Compressor Wheels vs Cast is:

  1. Lighter Weight (some cases it is heavier)
  2. More Room for Air Flow
  3. More Durability (Cast Wheels can Have Air Pockets Creating Weak Spots, But Billet Wheels are machined for Solid aluminum)
