Jay Leno drives a 1970 Dodge Charger with 1,650 horsepower

When Jay Leno says a vehicle might have too much horsepower, he's got our attention piqued. That's exactly what he thinks about the 1970 Dodge Charger Tantrum from Wisconsin-based SpeedKore Performance. While it still looks like a classic muscle car, the front end now features a carbon fiber hood and fenders. Underneath the lightweight parts, there's a twin-turbo, 9.0-liter Mercury Marine offshore boat racing engine with an astonishing 1,650 horsepower, or an only slightly less asinine 1,350 hp on pump gas. Jay is very mechanically intrigued by the Charger at the beginning of this video, and puts it on the lift to take a look at the underside. The engine plumbing is a thing of beauty, and the mill packs a massive radiator and intercooler to keep things running cool. Leno's drive in the Tantrum is especially interesting. The beastly engine is difficult to control, and anything above half throttle in most gears can spin the rear tires. The significant turbo lag also makes the power unpredictable. When Jay finally finds a straight piece of road, he puts the hammer down and rockets into the distance. And, of course, you know Jay's not going to end the video without some suitably smoking tires.

Fiat Chrysler to get $105M fine from NHTSA for recall woes

The National Highway Traffic Safety Administration is about to send a powerful message to automakers doing business in the United States, assuming reports of an upcoming $105 million fine against Fiat Chrysler Automobiles comes to fruition. In addition to the record-setting monetary fine, according to The Wall Street Journal, FCA will have to accept an independent auditor that will monitor the company's recall and safety processes and will be forced to buy back certain recalled vehicles. In other cases, such as with Jeep Grand Cherokee and Liberty models with gas tanks that could potentially catch fire in certain types of accidents, FCA will offer financial encouragement for owners to get their recall work done or to trade those older vehicles in on new cars, according to the report. FCA could reportedly reduce its fines if it meets certain conditions, though those remain unclear at this time. These actions against FCA are being taken after NHTSA began a probe into the automaker over almost two dozen separate instances where the government claims FCA failed to follow proper procedures for recalls and safety defects. Included in those safety lapses are more than 11 million vehicles currently in customer hands. These penalties and fines are separate from the investigation over security problems with Chrysler's Uconnect system that allowed hackers to obtain remote access into key vehicle systems in 1.4 million vehicles.

Before Jay Leno, this 1970 Dodge Charger was a SEMA star

When Jay Leno drives an awesome car, enthusiasts take note, and this week the internet blew up over the 1970 Dodge Charger resto-mod that starred in a recent Garage episode. But you might not remember: this strapping Charger, called "Tantrum," was one of the highlights of the SEMA Show in Las Vegas last fall. Here's another look at a true Mopar monster. The power: Yep, Tantrum has 1,650 horsepower. That's more than two Hellcats worth of power under the hood. It's a twin-turbo 9.0-liter Mercury Racing engine with a quad-cam four-valve setup. Basically, it's a V8 boat motor developed for cars. Mercury Marine is the crew that developed the V8 for the 1990s Chevy Corvette ZR-1. That all-aluminum LT-5 under the hood cranked out 405 hp – an astronomical figure for the time – and helped make the ZR-1 an icon. Take a listen to Tantrum's 9.0-liter Mercury mill below.

You might not know: Tantrum won the Best Domestic category of the GT Awards at SEMA – chosen by your author. The sinister looks were the hook, and the crazy engine solidified its performance cred.
