Kaase launches new Boss Nine engine kits

By Titus Bloom, July 24, 2014 -Created for use on common Ford 429-460 big-blocks -Simple assembly with conventional parts Winder, Georgia: For engine builders, and enthusiasts with ambitions in hot rod engine assembly, Jon Kaase has introduced the Boss Nine in a new kit form. Among the kit’s more prominent components, Kaase includes his noted semi-hemi cylinder heads with accompanying pistons, pins and rings as well as pushrods, shaft-mounted rockers and induction system. Everything to complete the full assembly is supplied. Though power production may vary from 500 to 1,000hp in naturally aspirated form and up to 1,500hp under forced induction, it is the engine’s evocative appearance and heritage that heightens its universal appeal. Predictably, options abound and powder-coated cast valve covers are available in silver, red and black. Indeed, in any color that can be identified by a paint code. In addition fabricated sheet metal covers are offered in natural aluminum finish. In performance the Boss Nine’s magic is ignited by increasing its stroke length from the original late-nineteen-sixties specification of 3.590in. “Those big-port heads,” contends Kaase, “don’t like stroke lengths shorter than 4in., and respond enthusiastically to 4.150in, 4.300in or 4.500in, all of which we use.” Because the longer 4.500in stroke causes the piston to protrude from the cylinder at bottom dead center, Kaase recommends a Race block or a “79” block, which has a 0.250in longer cylinder wall. Produced from 1979 to the mid-‘90s these can be identified by the nomenclature D9 on the block’s external surface. “They’re robust,” declares Kaase, “and we have one at the shop. It is 0.030in over-bored with 2-bolt main bearing...

How a clever pump design saves 4 to 6hp

Tumultuous change? Maybe not but KRC has uncovered significant power losses with unique new test equipment By Freddie Heaney, August 1, 2014, Photography Moore Good Ink Kennesaw, GA: Recently, Chant, the engineering authority in electronic-hydraulic control systems, delivered new testing equipment to KRC, the engine pulley and power steering specialists. Strikingly, the tester, the first of its kind, has uncovered power steering system secrets reminiscent of aerodynamic revelations found in a wind tunnel. A sophisticated one-off machine, it reveals that as engine speed increases in 1,000rpm increments one power steering pump can consume twice the power of another. [See Consumption tables at end of article.] The news, a defining moment for some, could contribute a decisive edge to not only NASCAR race teams who cherish every part of a horsepower gain but also to road race teams and short track oval racers. Surprisingly, the tester further confirms that a small 5.9cc pump is capable of developing as much flow as a bigger pump while consuming half the horsepower. During recent tests with several GM-style power steering pumps modified for competition, the tester demonstrated they absorb around 3.6hp at 8,000rpm engine speed. By comparison KRC’s Pro Series 5.9cc pump used on Aston Martin’s victorious Le Mans sportscars absorbs 1.9hp. All pumps were tested with 125psi of load applied, which is the average pressure generated in a power steering system when operating in the straight ahead position. Using data acquisition and a GoPro camera to identify power loses Beyond this the tester not only measures pressure and flow and calculates power consumption but also duplicates the data acquired on a racing...

Brian Brown prevails at 360 Knoxville Nationals with Charlie Garrett power

By Alfie Bilk, August 10, 2014 Hanover, PA: The feeling on Saturday night August 2nd was one of jubilation. Brian Brown (34), the gifted sprint car racer from Grain Valley, Missouri, had won the 24th Annual 360 Nationals at the Knoxville Raceway, in Iowa and Charlie Garrett’s home was filled with mirth! “It’s everybody’s dream to win the Nationals,” declared Garrett, “but it’s very difficult to do—it’s so fiercely competitive it’s even difficult to make the field! Of the 106 entries at this year’s event, only 24 cars are selected to race in the finals. They are the best of the best and this year we won it.” “The 360 engine is not my specialty,” admits Garrett, “I’ve only built two in my life, but Brian talked me into building one.” The 360s are not as powerful as the 410s but they are more durable, and will probably run 20 shows. Assuming you have sufficient, reliable power your biggest challenge is to qualify well.” Qualifying for the Knoxville Nationals, which is determined by points, begins on Wednesday night when the organizers run half of the entered teams. The remaining half is run the following night. The total points available are 500. Quickest time is worth 200 points, heat win is worth a further 100, and winning the A-main on Wednesday or Thursday evening is worth a further 200 points. Good point scores represent a good starting position. Brian Brown’s 360 sprint car accumulated 496. Almost the perfect score, they put him on pole for Saturday’s night’s big race. Brown has been racing sprint cars for 15 years, almost half...

Muldowney to attend 60th anniversary of NHRA US Nationals

By Martha Maglone Cha Cha unites with Garlits, Prudhomme and McEwen at Indy More than three decades after she won the NHRA US Nationals, Shirley Muldowney will be one of several drag racing stars returning to the Indianapolis track to celebrate not only her own memorable victory there in 1982 but also the NHRA’s 60th anniversary at the famed track. Scheduled for Labor Day weekend (Aug. 27 – Sept.1) the three-time NHRA national drag racing championship title holder with 18 career victories and the first female winner at Indy, Muldowney will attend this year’s spectacular to reunite with her fans and accept a presentation scheduled for Saturday. Recently moved to Huntersville, NC from her home state of Michigan, Muldowney earned the greatest victory of her distinguished Top Fuel career in September, 1982 at Indianapolis. Her only victory at the prestigious drag race, the triumph propelled her to a third NHRA championship title and international prominence, portrayed by the 1983 movie Heart Like a Wheel that characterized Muldowney’s life and career. “The fact that it was Indy and the final pair was the quickest and fastest side-by-side run ever at the time made it so special,” Muldowney has said. “There is a lot of prestige gained by winning Indy because people remember Indy wins more vividly than any other,” she added. “It’s the biggest race. I think its sporting credentials and its rich history make it so important. A race win there is always the one most cherished. Not every racer can say they have won it. I can say I have won it.” At that time, Muldowney called the...

Garlits re-sets electric dragster record at 185.6mph…with a little help from the Magic Kingdom!

Archie Bosman, August 10, 2014 On Friday, August 8, during a record attempt at Bradenton, Florida, Don Garlits (82) and his team encountered a mechanical failure in one of the electric motors of his Swamp Rat 37 dragster. Luckily they were able to borrow a spare motor from Disney World. They worked all night, they returned on Saturday, and they re-set the record. “The power of the Magic Kingdom saved the day!” said Don. Earlier on Friday they made two runs at 183mph and determined that greater electrical capacity was needed to reach and surpass 200mph. As a result, the motor package, which consists of six electric motors, is being returned to the Ohio manufacturer Lawless Industries where the motors will be upgraded from 180hp to 250hp. “It didn’t smoke the tires but it was slipping around pretty good,” Garlits explained, “so we will upgrade the tires from Alcohol to Big Fuel for further record attempts. I’ve got a big deal going on at the upcoming US Nationals, so we won’t do anything more with the electric program until after that.” How does it feel to drive? “I shift it, I have two-speed transmission and I can feel when it’s time to shift. But it is totally different from a conventional dragster. When you are sitting on the starting line, it is quiet and you just step on it and it flies! That takes some getting used to. In a conventional dragster it makes all kinds of noises and the car’s rocking all around. But in the electric dragster, hell, the crew can come up to you and talk...
