Drag racing is not always about the biggest dog in the fight, but how much bite the dog has.  The classic formula to get the most bite out of your race car is to reduce weight and add metric tons of horsepower.  This type of action is a requirement for most old school muscle cars because of their size, but what if you start with a tiny car with an even smaller motor?  Bola De Humo Racing has the answer to that question, and it runs in the sevens at 175 miles per hour.

Bola De Humo racing’s car is a first generation Mazda RX-7 that had a production run from 1978 until 1986.  These cars came from the factory with a small CC Wankel rotary engine and either a manual or automatic transmission. The RX-7 was known more for having great handling rather than killer straight line speed.

Most first generation RX-7’s seen at the drag strip have some type of V8 stuffed into them, but not this single digit monster. The team at Bola De Humo decided to keep the 1.3 liter, semi peripheral rotary in the car. The 76mm displacement of the engine is actually LESS than the 88mm Precision turbo on the car.  Don’t let the small motor fool you, though, as the car put down 850 horsepower to the wheels on the dyno while lifting at 8,000 rpm. All of this power is put down through the stock chassis that was worked over by Allegro Racing to be certified to go single digits.

The video provided by our friends at www.1320video.com shows the RX-7’s first hit down the quarter mile with this new setup. During the pass the car cut a 1.19 60’, 5.13 at the 1/8^th mile, and ran a 7.95@175 all while having a very spirited launch. Click play to hear the pure wicked evil sounds of a rotary that rips!
