MONROE'S CHAMPIONSHIP WINNING 8-71 BLOWER AND DUAL T2 FUEL SYSTEM

James Monroe's 2012 championship-winning engine was built by Jim Evans of Rolla Competition Engines in Rolla, MO in early 2012.  Evans is a famed carburetor builder in the circle track and drag racing arena and is also the car owner of Troy Galbraith's 2011 NHRA Division 3 Top Dragster championship entry.  The 540" BBC features a Brodix Aluminum Block, Callies crankshaft, Carillo connecting rods, Ross Pistons, Moroso oil pan and pump, Pro-Filer Performance cylinder heads and T&D shaft rockers.  You can see all of the photos of this build by clicking on the engine below.

To compliment the engine Monroe utilizes a Transmission Specialties "Tech-10" torque converter and Proline 5500 Series transmission, a Blower Drive Service 8-71 "Hi-Helix" supercharger and Fab Shop "zoomie" headers.  The race car of choice was a Spitzer Race Cars built 272" slip-joint dragster that has won vitrually everything there is to win in this class since it debuted in 2009.  

We are extremely proud of the fuel system on this race car.  The components are solely from Ron's Fuel Injection and are the basis for what is now the "Black Widow" blower fuel system offered by KillerRONS.COM.  To our knowledge this is the first time all of these parts have been utilized together in a blown fuel system.  James Monroe,  his father (Mike), Scott Offermann of KillerRONS.COM, Jeremy Camacho of Ron's Fuel Injection and Jim "Shorty" Rader put many hours and much thought into the development of this "protoype" fuel system.

This combination carried Monroe to the 2012 NHRA D3 Top Dragster championship posting wins at the Route 66 Raceway (below) and National Trail Raceway divisional events as well as a divisional runner-up at Beech Bend Raceway Park.  Monroe also garnered runner-up finishes in the JEG'S All-Stars event and inaugural Moser Sportman Shootout.  The car's best performance numbers during the season were 6.387 and 212+ MPH.  This was with less than 15 psi of boost and with the utilization of only 6 of the 8 possible port injectors in use.



The engine was fully disassembled and checked by RCE the week after the final race of the season.  All checks were great with no signs of cylinder wear and no bearing degradation other than normal wear.  The engine was freshened along with intake porting and then tested on the dyno the first week of December.

What now? The engine will be installed in Monroe's new Spitzer race car and topped with a Blower Shop 10-71 "Hi-Helix" supercharger for the upcoming 2013 season.  The fuel system will be unchanged with the possible addition of the final two port nozzles as necessary.  Boost levels will continue to be in the mid-teens.
