RJR has been drag racing since 1969 on the track, and maybe the street, and built his first Hot Rod, 1940 Ford 3 window coupe w/283 12.5-1 compression sbc, in 1967. Since then has opened RSC Performance Group Inc that owns rscspeedshop.com, efispecialist.com and Radical Street Cars, a small brick & mortar shop specializing in Performance Street Cars, Resto Mods and Pro Street builds and performance mods. Check out the websites. We price match all online stores, and by phone we sometimes beat pricing. (910) 833-7565
RSC Speed Shop is a complete aftermarket, performance site with over 700 manufacturers, while EFI Specialist focuses on Standalone EFI Systems, TBI EFI conversion and conversions and induction, including Forced Induction and Nitrous Systems for Track and Street. Our Mutant Mustang is a 1,200 HP, nitrous fed, daily driver w/4 link back half by RaceTech Racecars in Burlington, NC. The 396 stroked LT1/LS Converted ignition, SpeedTech plumbed nitrous system, is controlled by a Holley HP ECU, Rossler brake in a highly modified 4L60E 4 speed OD transmission. The fabricated 9” housing runs a locker with 4:30 gears sending the Fox Body in the high 8’s down the 1/4 mile on a good day.
