Harper's Racing is the Only Licensed Buick Grand National Specialist in the Southeast.

If you've been itching to make your Buick Grand National faster and even more awesome than it already is, you need to get it upgraded at Harper's Racing in Fort Lauderdale, Florida. Rick Harper has been in the business of racing and building high performance Buick Grand Nationals for over 20 years. He has successfully and consistently put them in the 11, 10, 9 and now 8-second quarter mile bracket, with the help of ASE certified mechanics Emri Visztenvel and Byron Liu. Emri, a master mechanic, has 23 years of experience working on Buick Grand Nationals. Byron is a genius that specializes in electrical work on these cars.

Harper's Racing has established clientele all over the country from Florida to California and as far north to Canada. Just in Florida alone, he has serviced over 840 satisfied customers. Rick's car racing experience dates back to the late 60's and early 70's when he drag raced Super Stock (SS/HA & B/SA, D/SA) Pontiac Firebirds. Working at Champion Racing Engines in Montreal, Canada, he built small block Chevy and Pontiac engines. Eventually he moved to Florida. It was here Rick started experimenting and racing Buick Grand Nationals as a hobby. He was so successful with them that his friends convinced him to open a Buick Grand National high performance racing shop in 1990. Named Harper's Racing, Up to date, Rick has built over 585 motors. Rick is now working on three New Projects for this year, his first is a Grand National from Quebec Canada. The owner Stephan Jacques from St. Leon de Standon has a beautiful craftsmanship GN with a Stage 11 motor prepared by Rick. The car should run low 8's at 170 mph. The next project is Nestor Valdes with his 87 Grand National from Fort Lauderdale. Rick's expertise in building high performance engines for Buick Grand Nationals has spilled over onto his personally owned Z06 Corvette. Some trick modifications gave it over 400 rear wheel horsepower. With the LS1 Edit and the help of Dan Tucker of Kelley's Chevrolet in Hallandale Beach, Florida, it produces 11.10's @122 mph on 315/35/18 BFG Drag Radials with 93-octane fuel. It still gets over 30 MPG at 75 MPH. Rick's next project is to purchase a 2008 Z06 with a 505 HP 427cubic inch motor. His project is to make it enter the mid 10's on Drag Radials and still achieve 26 mpg. Rick purchased GNX #180 in July of 2007 from the original owner out of Rhode Island. This car has always been garage kept and never driven in the rain. Now it's going to be only garage kept for future investment.

Rick's ingenuity in racing has lead to a new development for Buick Grand Nationals. Working with a major computer company, he has finally come up with a new Mass Air Flow Sensor. It replaces the original GM units, which were discontinued six years ago. Now the computer readings correctly match the original GM units and they are for sale. The newly designed units come without any cones in the middle and they have only one screen for better airflow. They have been corrected to compensate for the additional airflow, and they have a fiberglass printed board instead of the thin board that GM used. These units work extremely well with 9" K&N Open Air Filters and any compatible street or race chip. One hundred units have been sold to date and none have come back defective, proving the units work.

Call Harper's Racing for more details on this New Mass Air Flow Sensor Unit.
