Here's a couple shoots of CODE3 having a blast with  an LS1 powered Gen 4.  Scott Townley built this car with his dad in 9 days in his garage.  Does it look like he's have fun?

 

 

Here's Chris Herb with his new Gen 4 powered by an Outfront 3.0L R6 Subaru motor.  This is the latest rage in light weight motor setups.  The interesting feature of this 6 cylinder motor is the length, only 1.5" longer than Subaru's 2.5L four cylinder motors.  This short length and the light weight make the R6 a perfect combination for sandrails to maintain optimal handling through the dunes. 

No problem bring up the front wheels on Chris' new car with over 500HP.
