Holy Moly! Hennessey Jeep Trackhawk Rips 0-60 In Just 2.3 Seconds - Sub 10 Second Quarter Mile

It takes a special kind of person to look at a Jeep Trackhawk and think “That’s nice. Shame it doesn’t have a bit more power”. John Hennessey – Top Gear’s favourite Texan – is one such person. As standard these things make 707bhp from a 6.2-litre supercharged V8 – good for 0-60mph in 3.5 seconds and a quarter-mile in the mid-elevens. John Hennessey’s Trackhawk is…faster. Much faster.

That’s thanks to something called the HPE1200 upgrade. It involves upgraded pistons, rods, ported cylinder heads, a camshaft upgrade, long tube stainless steel headers and a bigger 4.5-litre supercharger. Running on 109-octane fuel and 22psi of boost, Hennessey’s Trackhawk makes 1,003bhp and 892 lb-ft. At the wheels. At the crank, you’re looking at 1,200bhp and 1100 lb-ft. Or if you’d rather, enough to win a tug-of-war with a medium-sized aircraft carrier.

@MD- Running 22psi of boost will tend to do that to an engine. Piston-Block Wall-Hole.

109 octane fuel? Is that race fuel or something? Not from any pump I have pulled up to.

It's not pump gas. Hehe High octane race fuel is expensive, but has its purpose.

109?? The highest I've seen is 101 and that was labelled "Racing Fuel"
