Rolls Royce Silver Shadow with Hemi Engine Named World's Fastest by Builder at SEMA

The World’s Fastest Rolls Royce stopped foot traffic at SEMA (Specialty Equipment Market Association) at the Las Vegas Convention Center in Nevada. Little Joe’s Street Rod Shop named it and put it on display in the show as an outside feature vehicle.

Luxury additions on the 1970 Silver Shadow include a leather trunk with matching battery covers and one of four television sets

The 1970 Rolls-Royce Silver Shadow is a daily driver. The owner has two of the same models and wanted to do something wild with one of them. “He has a fascination with Hemi engines and wanted more power on his Rolls,” said Joe Richardson of Little Joe’s Street Rod Shop. “As a result the modified Rolls Royce is a plush luxury car with a huge motor.”

It has a fuel injected 572 cubic inch Chrysler Hemi motor. There is also a nitrous-oxide system and a BDS 671 style supercharger for more power. “There is a K&N air filter on the end of the idle speed control motor,” said Richardson. ” Richardson ran the Hemi on a dyno and said he made 1350 horsepower.

The Silver Shadow went to Richardson as 6200 pounds of unibody stock. “We cut from bumper to bumper and rocker to rocker,” he said. “We had to gut the car for a complete aftermarket chassis.”

“All the suspensions from Chris Austin Chassis are either chrome plated or polished stainless,” said Richardson. “The entire roll cage is hand stitched leather. It’s made like a baseball stitch and is very time consuming. It took 8 hours to do one single bar and five months to finish the interior.”

The Silver Shadow has stock bumpers, door handles, and lights. “We received all expenses paid invitations from corporations at SEMA to tour car shows in Germany, France and Canada,” said Richardson. “Rolls Royce is making a comeback.”

K&N has released a new high flow custom intake assembly (RK-3930) for all 2008, 2009, 2010, 2011 and 2012 Harley-Davidson Touring Models. See the complete list of motorcycles below. It is designed to fit neatly behind your Touring Model’s air filter cover as it provides a substantial increase in airflow resulting in additional horsepower and torque.

The RK-3930 includes an oversized original high flow air filter which provides an extra large filtration area while offering longer service intervals. This filter, like all K&N original high-flow filters is washable and reusable, pre-oiled and ready to ride.

A Bump-Seal is used at the base to provide a perfect seal. The cast aluminum backing plate includes built-in, internal breathers. A bolted-in, dyno-tuned velocity stack increases airflow velocity into the throttle body.

Spacers and hardware are included to mount your stock Harley Davidson air cleaner cover. Fuel management modifications are not necessary to obtain increased performance.

Covered by our famous K&N Million Mile Limited Warranty, it will be the last air filter your motorcycle will ever need.

Applications for the RK-3930 are as follows:

“I like the constant change and the options of so many different designs,” said De Encio. “There are so many ways to express yourself when you customize a vehicle. One of his designs was the star of the Infiniti booth at SEMA (Specialty Equipment Market Association) at the Las Vegas Convention Center in Nevada.

“We call it the G37 Sedan Concept,” said De Encio. “Our design was European, inside and out. Our G37 Sedan is equally ready for the Autobahn as it is for a night on the Las Vegas Strip.” Automotive Design Concepts extended the fenders for more than 2.5 inches for a wide body approach. “The paint job, however, really stood out,” said De Encio. “It’s from PPG Industries Vibrance Collection Radiance line. We put eleven coats of Sunset Red Candy paint on top of a gold base.”

K&N supplied De Encio with its 69-7082TS air intake system. “K&N, hands down, makes the best air intake kit on the market today,” he said. “K&N sees the fit and enhances the way vehicles perform. We noticed the increase in horsepower immediately. We also equipped our car with a K&N oil filter.”
