Shelton Racing Enterprises, Inc. proudly owns a state of the art SuperFlow 902 Dynamometer with over 10 years of operator experience.

After many years of renting dyno time on other's dyno beginning in 1990 on the Atlanta Speed Shop's SuperFlow 800 Dyno, I realized to build the best racing engines you must have a dyno to test, tune and make sure your work is as designed before it leaves the shop.  For a professional engine builder, a repeatable, precise dyno is mandatory.

 

 

 

 

 

 

 


I spared no expense in the construction of this dyno cell and associated equipment.  The SRE Dyno Facility is one of the nicest in the Southeast.  I completed dyomometer training at Superflow's headquarters in Colorado Springs, Colorado and my facility was inspected and certified by Superflow in 2006.  

The dyno features an independent thermostatically controlled air system that feeds the engine while the cell creates a vacuum to remove all engine fumes so engine air is not contaminate during testing.
