Hot Rod Garage series premieres with 700-hp big-block Jaguar XJ

Roadkill hosts Mike Finnegan and David Freiburger have broken up - kinda - to spin off a new show, Hot Rod Garage, that mostly gives up the driveway and parking lot wrench work for the confines of a garage. We say kinda because while Finnegan is the primary host for Hot Rod Garage, Freiburger plays guest host and the new show starts off by wrenching on the Roadkill Draguar project car.
What's the Draguar? It's a 1974 Jaguar XJ12 that's about to be force-fed a 383-cubic-inch Chevrolet long-block engine with tidbits like Holley carbs, a Weiand 6-71 roots blower and a "custom WillBlow transmission," all good for about 700 horsepower. After that Finnegan gets into swapping parts on his wife's El Camino and some TIG welding lessons.
You can check out the first episode below. And in case you're worried, no, Roadkill isn't going away.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.

Why Ask Questions When You Already Know The Answer?
"Is it fast?"
We get that question a lot. Several times a month, in fact, and it comes from every corner of our lives - friends, family, complete strangers and even colleagues from time to time. And it's an understandable query. After all, speed, either in a straight line or around a twisty bit of tarmac, is a universally accepted line of demarcation between the typical family sedan and something much more fun and therefore desirable.
