Justin’s Performance Center out of Maryland has made a name for themselves for building and racing the fastest NMRA Factory Stock cars year after year. They have also ventured into NMRA’s Pure Street and Real Street classes, along with sponsorships of Mustangs in other classes. The silver S197 car JPC built has raced all across the country in True Street events and even participated in Hot Rod’s Drag Week event. After seeing Justin build the first 2005 Mustang in the 10’s, 9’s and 8’s – a Canadian customer decided to have Justin and the crew at JPC build him a turnkey street monster. The specifications given to the JPC team were that it must be streetable and run in the eight second zone.
Using the experience they have gained in building, driving and racing some of the fastest late model Mustang’s in the country – they got to work on this new project. The 2005 Mustang was stripped down to just the bare chassis and then the work started. Some chassis stiffening was added along with a custom roll cage to protect the driver. You can never take safety too seriously, especially with over a thousand horsepower at hand in a street car.
The front suspension was handled by Anthony Jones Engineering strut and coil over setup. Anthony Jones was one of the first to make a tubular K-member and front end kit for the Mustang. And out back they have Racecraftfabricated nine inch housing, anti roll bar, and thru-floor upper third link to get the car to leave hard. It is hard for you to go wrong with Racecraft, since them building some of the fastest heads up Mustangs in the country. Metco, who builds machined aluminum control arms, provided the rear lower control arms to round out the package. The car also features a hidden and removable parachute mount, which was placed behind the license plate area.
To make things comfortable for the drive,r the Kirkey seat was mounted on the factory seat track so it will move forward or back and they retained the factory steering wheel for now, along with the power steering.
The engine is built by Rich Groh Racing and started with a Ford Racing Modular block with RGR four bolt billet main caps, to hold the custom billet crankshaft in the block under all that boost. The Oliver connecting rods and CPpistons were also custom pieces spec’ed out by RGR and JPC.
The short block comes in at 322 cubic inches and it is topped with RGR’s cnc ported three valve heads that have been hand finished. RGR also spec’ed out the camshafts, topped off with titanium retainers and Jesel solid followers and tappets. The intake is the JPC racing intake manifold with a 2003 Cobra single blade throttle body to get the air in. The LS style coils were used and custom mounted under the intake to keep the clean look under the hood. Rich has been building some of the fastest engines in several of the NMRA classes for years and that is just one of the reasons JPC use him for their engine needs.
The engine is fed all of the boost it can handle by a pair of Precision Turbo 67 mm liquid cooled units to keep the car streetable. The turbos pump the compressed air into a custom JPC front mount air to water intercooler, mounted in front of the radiator. The timing and fuel controls are done with a Big Stuff 3 stand alone engine management system tuned by the guys at JPC, and it was nicely hidden where the passenger air bag would be. The power is run through a TCI TH400 race transmission and a TCI Pro X race converter before it is sent to the nine inch rear end.
The car also has a full length custom fitted stainless steel exhaust system that exits out the rear bumper. The full exhaust system along with the turbo keeps it very quiet for the unsuspecting encounter on the street. Aerospace Components gets the call with race brakes all the way around and even the dual caliper set up in the rear. All of the carpet and interior panels were cut and fitted around the cage and other additions to give the Mustang that street car feel.
The first time at the track was at the NMRA Finals in Bowling Green Kentucky. The team was fighting new car bugs but they still ran a beast of 9.54 at a low 114 mph. As you can see by the mph, there is a lot left in the beast. Additionally, they were fighting transmission issues most of the weekend with Justin even taking the transmission out of his True Street Mustang to try to get it fixed for eliminations, but they could not make the call for the first round. The have estimated the horsepower to be in the 1200+ range, so I would look for the car to lay down some low eight second time slips and even dip into the seven second range and still have the ability to go out and cruise around.
