Generation I, of which there were different versions and displacements for Chrysler, DeSoto, and Dodge cars throughout the 1950s. The reemergence of the Hemi as the Generation II “Elephant” motor, used in both racing and to power some of the fastest and most desirable street cars of the day, and then the modern Generation III Hemis, used in Ram trucks and Dodge and Chrysler performance cars.

How well do you know your Hemi history? Below are some questions and fun facts about the Hemi. It’s not intended to be a test of your memorization of bore:stroke ratios, but rather to arm you with some trivia for the next time the conversation turns to Hemi engines.

In what year did Chrysler introduce its first Hemi engine?

Called the FirePower, it was used in Chrysler passenger cars from 1951 to 1955. Most were equipped with a two-barrel carburetor and produced 180 horsepower until the 1955 model year.

Did you know the Hemi was actually outlawed from racing in the Indy 500?

In late 1952, a specially-prepared 331 CID fuel-injected Chrysler Hemi engine, producing 410 horsepower, was fitted to a Kurtis Kraft 500A roadster (a state-of-the-art Indy car of the time) and tested at the Indianapolis Motor Speedway. It ran a simulated 500 mile race which it completed four mph faster than the race record. Alarmed, officials lowered the maximum displacement for stock block engines from 340 CID to 270 CID. Chrysler chose to withdraw.

The 354 CID engine was released for the 1956 model year. The 354 was installed in the Chrysler 300B and available with an optional 355 horsepower version, making it the first American passenger car engine to be rated at one horsepower per cubic inch.

Was the original 426 Hemi intended to be a race-only engine?

The Generation II Hemi engine displaced 426 CID, with dimensions so large it was nicknamed the “Elephant” by Chrysler engineers. Intended only as a race engine, Richard Petty debuted the Generation II Hemi at Daytona, where he laps the entire field on his way to winning the Daytona 500. It’s was a clean 1-2-3 sweep for the 426 Hemi at the 1964 Daytona 500. Chrysler was instructed to offer the Hemi to the public before the engine could return to NASCAR.

Which driver was the first to use a Hemi to crack 200 mph on the strip?

Don Garlits shattered the 200-mph quarter-mile barrier in a 426 Hemi-powered Top Fuel dragster in August at Island Dragway with an ET of 7.78 seconds and trap speed of 201.34 mph. If you’re into nostalgia drags, K&N manufacturers the PS-3001 oil filter that’s a perfect match to the needs of an “Elephant” motor running the strip.

K&N RK-3947B intake for Harley-Davidson motorcycles

Most Harley riders would love a bolt-on solution that adds a little extra acceleration when passing slower traffic up a hill or going around a truck. K&N has the answer for many 2008 – 2015 Harley-Davidson FLT and FLH riders with its RK3947B high-flow air intake system, which adds over seven horsepower with a simple installation.

The Twin Cam motorcycle engines have been manufactured by Harley-Davidson since 1998. Although these engines differ from the Evolution engine, which has been evolved from the series of single camshaft, overhead valve motors that were first released in 1936, they share a number of characteristics. Both engines feature two cylinders in a traditional Harley-Davidson 45° V-twin configuration, both are air-cooled (although some touring models use liquid cooling for the cylinder heads) and activate valves via push-rods.

When Electronic Fuel Injection (EFI) first became available in 2001, it opened up a world of opportunities for upgrading and customizing the performance of the Twin Cam engine.

In order to get the most out of your EFI system, you need an air filter system that flows better than stock. The K&N RK3947B high-flow air intake system has been developed to add horsepower and acceleration to your Harley through an increase of up to 50% more air flow, which the EFI system can turn into more power.>

The K&N high-flow air intake system eliminates the stock OE air cleaner assembly and replaces it with a complete intake assembly. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. Inside the intake system is an oversized K&N air filter feeding a dyno tuned velocity stack specific to the Twin Cam which directs airflow to the engine. A black powder coated aluminum cover with a subtle K&N logo finishes off the package.

And the performance benefits of the K&N RK3947B intake system isn’t just advertising copy. In fact, K&N dyno tests show an estimated 7.03 horsepower increase on an otherwise stock 2015 Harley Street Glide.

The key to improved airflow through K&N air filters is that they’re manufactured from several layers of pre-oiled cotton filter media, rather than restrictive paper often found in many replacement filters. K&N filters also provides outstanding microfiltration, removing the most damaging particles to your engine, to ensure a long engine life for your Harley. K&N conducts its own in-house ISO 5011 air filter efficiency testing, which follows International Standard Organization procedures to verify that each K&N air filter meets these standards.

The only maintenance required for a K&N Harley intake kit is a service you can do yourself in no time at all. Once a year, depending on riding conditions, with just the K&N air filter cleaning kit you can easily renew your air filter, and prepare it for another year of riding. Your one K&N air filter is designed to last for the lifetime of your bike, which K&N guarantees will perform for up to 1,000,000 miles or 10 years without requiring replacement.

Kyle Benjamin won the pole for the NASCAR K&N Pro Series East race at Greenville Pickens Speedway in South Carolina. It was his fifth pole of the season.

Benjamin won the third race of his K&N Pro Series career and his second in the past three races. This one was a little more meaningful though. He was second in the K&N Pro Series race at Iowa Speedway in July, but was awarded a win for being the top-finishing driver from the K&N Pro Series East. Todd Gilliland, a driver in the K&N Pro Series West, won the race, which pits drivers from the K&N Pro Series East and West.

“I had a lot of family out tonight, a lot of people I know watching me,” Benjamin said. “It was really cool to win in front of them.”

Kyle Benjamin won the NASCAR K&N Pro Series East race at Greenville Pickens Speedway in South Carolina. It was the third win of his K&N Pro Series East career.

Benjamin won the pole, his fifth of the season, and led all 140 laps in the Kevin Whitaker Chevrolet 140. The K&N Pro Series East made its second visit to Greenville Pickens Speedway this year. In March, Benjamin led 122 laps and ended up second to Justin Haley.

“It’s cool to get your first win of the year that way,” Benjamin said. “We’ve been working so hard all year. All the guys have put in a lot of hard work at the shop. We’ve been close, had a lot of bad luck. You can feel the history here at Greenville Pickens, it’s pretty cool too.”

Kyle Benjamin led all 140 laps of the K&N Pro Series East race at Greenville Pickens Speedway in South Carolina.

Van Wieringen had a historic race at Greenville Pickens Speedway. She finished third, the first podium finish of her career. It was the second-best finish by a woman driver in K&N Pro Series East history. Kenzie Ruston was the runner-up at Iowa Speedway in 2014.

“I’m on top of the world,” Van Wieringen said. “It’s like a win. It shouldn’t feel like one, but it definitely does.”

Van Wieringen, a rookie driver in the K&N Pro Series East, has three top-10 finishes this season. Her previous best finish was a 10th place at New Smyrna Speedway in Florida to open the season.

Kyle Benjamin leads the field in the NASCAR K&N Pro Series East race at Greenville Pickens Speedway in South Carolina.

“It was definitely exciting,” Van Wieringen said. “I had to work my way up from ninth to third. There was a lot of good racing going on. I got to give credit to Haley for the crossover move before the caution. That was amazing.

“This is like a win to me because we have had so many problems this year. I am so happy. We finally have the finish that I think we need.”

Brandon McReynolds was second. Ronnie Bassett Jr. finished behind Van Wieringen in fourth place, followed by Haley in fifth place.

“We struggled in practice, a lot more than I expected we would,” McReynolds said. “But when they dropped the rag, we knew we had a good car and came up just a little short. The 40 was better on the long run. All in all a good finish for us.”

Haley leads the K&N Pro Series standings after 12 races. He leads Benjamin by 30 points with two races to go. The next K&N Pro Series East race is at New Jersey Motorsports Park on Sept. 17.

The Ultimate Funhaver is a 2015 F-150 on-and-off road beast with five Recaro seats ready to give passengers the ride of their life

What is more fun than riding copilot in a drift car? Try buckling into one of four Recaro race seats in the Ultimate Funhaver. Vaughn Gittin Jr. is known for his incredible talent behind the wheel, but when it was announced that he would be building a 2015 F-150 with on-and-off road capabilities, we couldn’t wait to see what he had up his sleeve.

The F-150 was released during the 2014 SEMA show. The truck, which was built by Kibbetech Offroad, featured a 3.5 liter EcoBoost V6, Magnaflow exhaust, custom Currie full-floating F9 rear end, and a K&N air intake.

Since its debut, the truck has attended several events including the recent Auto Enthusiast Day in Anaheim, California. Vaughn Gittin Jr.’s Ultimate Funhaver was seen drifting the course in typical fashion, but an additional element was added this year that caught the crowd by surprise.

K&N driver Vaughn Gittin Jr. is well known in the drift world, but his 2015 F-150 is a one-of-a-kind vehicle that extends beyond the drift track into the off-road enthusiast group

As passengers piled into each seat, buckled up, and pulled out their phones to catch the action, each rider quickly realized they were about to get much more than just a drift demonstration. As the truck drifted around the track alongside Cody Currie’s Pro Lite Race Truck, Vaughn Gittin positioned the F-150 towards the ramp in the middle of the course, mashed the gas pedal and went airborne. The jam-packed truck did not see much height during each jump, but it was also accommodating five people, including Vaughn Gittin Jr. Regardless, the crowd cheered as the truck landed safely and continued its demonstration.

This was not the first time Vaughn Gittin Jr. has jumped his F-150 at an event. The truck has seen quite a bit of airtime including some dirt action during a Speedhunters photo shoot last year.

The K&N-sponsored driver is always ready to put on a great show, but when the Ultimate Funhaver is present, there’s no telling what Vaughn Gittin Jr. will do out on course. As for the lucky passengers that rode along in the tricked out F-150, they will probably be talking about their experience for quite some time. By the looks on each of their faces, no one was disappointed by Vaughn Gittin’s show at this year’s Auto Enthusiast Day.

Tyler Dippel won the NASCAR K&N Pro Series East race at Mobile International Speedway in Alabama in March. He took the lead on lap 31 and led the final 124 laps of the race.

If it weren’t for flat tires, Tyler Dippel might be contending for a NASCAR K&N Pro Series East championship in his rookie season. The rookie driver, one of the NASCAR Next drivers, won a race and posted six top-10 finishes in his first 11 races in the K&N Pro Series East.

He started the season with a pair of eighth-place finishes in the first three races and won his first K&N Pro Series East race in his sixth career start. He won the K&N Pro Series East race at Mobile International Speedway in March.

“We got off to a pretty strong start there,” said Dippel, who drives for HScott Motorsports with Justin Marks. “Probably the midseason we struggled a little bit with flat tires and breakdowns a little bit. We need to get back going again as a team and rally back. We’ve been running good the last three races. It’s been really good lately. I think it’s been a success. We were struggling pretty bad in the middle of the season there. I think we are starting to turn it around. Hopefully we can finish off strong too.”

In the race at Mobile, Dippel qualified fifth and moved up quickly. He took the lead from Dominique Van Wieringen on lap 31 and was out front for the remaining 124 laps of the race.

“We just unloaded really, really good,” Dippel said. “It was one of those few times when you have the absolute perfect car. Nothing to complain about. The car was absolutely perfect. We started fifth and got up to third really quick. Just cruised around, tried to save my stuff. The race really unfolded in my favor and we came away with it there.”

Dippel enjoyed success early in the season. The 16-year-old driver was also learning how to market himself and his team through the NASCAR Next program. He said it was a huge honor to be part of the class and he embraced the opportunity to follow drivers like Kyle Larson and Chase Elliott who went through the program, too.

“You could be one of the next ones because you’re following exactly what they did,” Dippel said. “We’ve gone through a lot of social media training. It helps marketing us, getting our names out there. It’s been a huge help and it’s great to be a part of. It’s a great group of guys to hang out with.”

Dippel went through a six-race stretch in which he finished outside the top 10. He blew a tire at Bristol Motor Speedway in Tennessee. He blew a transmission at Virginia International Raceway. He had tire trouble again at Dominion Raceway and Columbus Motor Speedway.

Tyler Dippel won the NASCAR K&N Pro Series East race at Mobile International Speedway in his sixth career start. He is fifth in the K&N Pro Series East standings with three races remaining.

“The team meshed together really well,” Dippel said. “I got a good group of guys behind me. We got stuff figured out in the beginning. We just had a couple of breakdowns, a couple of blown tires. A lot of bad luck there in the middle more than anything.”

He bounced back in his last few races. He was 10th at New Hampshire International Speedway and seventh at Watkins Glen International in New York. In the race at Iowa Speedway, which pitted teams from the K&N Pro Series East and West, he was 14th overall and eighth among East Series drivers.

Through 11 races, Dippel is fifth in the NASCAR K&N Pro Series East standings. He is two points behind Hunter Baize for fourth place and 15 points behind Austin Theriault for third place.

“I would like to be a lot higher. We are really capable of it,” Dippel said. “All the bad luck we’ve had this year, I would like to be higher. I think we should be a little higher. We are a couple points away from fourth. Third we’re not too far back from either. We are going to strive to move up here in the next three races. I think it’s definitely possible.”

There are three races left in the K&N Pro Series East schedule. The teams will visit New Jersey Motorsports Park and Dover International Speedway in Delaware before the season ends in September.

“The car keeps getting better. I keep getting better as a driver,” Dippel said. “Just working together, we just keep getting better. I would like to pick up a win in the last three races here. That would be the ultimate goal. I think the rest of the season will be good for us.”

Racing in the K&N Pro Series East has given Dippel the opportunity to hone his racing skills. He said the longer races and the style of cars have helped him develop as a driver.
