‘The Fireball’, John Urist is most famous for his NMRA Street Outlaw exploits. The multi-time champion is a household name within that sanctioning body, and because of that rock star status, he’s also well-known outside of the NMRA circle.

Up until the middle of the 2015 NMRA season, Street Outlaw was a 1/4-mile class. However, the sanctioning body shortened the race distance to help bring in more racers. Being used to the 1/4-mile format, the change meant Urist and other NMRA racers had to reconfigure their cars accordingly, and run against those that were already sorted out for 1/8-mile competition.

John Urist’s hard work paid off at The Strip in Vegas with a win at SCSN.

The biggest change Urist made to his program was a switch back to a ProCharger F-3R supercharger from the turbo he’d been running. Urist is known for swapping back and forth between a turbo and supercharger depending on which he thinks has a competitive edge, and for his 1/8-mile program, Urist likes the ProCharger. Even though it took a small learning curve, with a win in Xtreeme Drag Radial at the most recent Street Car Super Nationals at The Strip in Las Vegas, it appears he and the Hellion A-Team have it figured out.

The ProCharger series of F-3R race superchargers, of which there are three, are capable of supporting between 2,100 and 3,000 horsepower. Maximum boost is between 40 and 50 psi, depending on which you choose. The difference between the three offerings is the amount of air each can move. The inlet hose diameter, inducer diameter, and exducer diameter are the only differences. Thinking of a supercharger like an air pump, the larger units are able to move more air than the others. The outlet hose diameter and outlet inside diameter remain the same, as does the supercharger’s gear ratio. Also, like much of ProCharger’s offerings, the F-3R is self-contained, using its own oil instead of engine oil.

For Urist, the F-3R he uses with his program allowed him to get down into the 4.30s in XDR competition at the Street Car Super Nationals, and get the event win in the process.
