I promise that this post wasn’t by design, but rather is completely a coincidence that it follows hot on the heels of the neat supercharged E34 540i 6-speed from yesterday. How do you possibly trump that potent hot rod? Well, starting with a M5 is probably a good bet.
If the E34 was a potent athlete, the E39 comes across as a consummate professional. It was immediately the new benchmark for sports sedans once again, and when BMW finally did make the call to bring a M5 to market they produced what many consider to be the definitive driver’s car in super sedan form. Whatever you had from the period, the M5 was just plain better. With 394 horsepower kicking out of is snorting S62 V8 and mated solely to a 6-speed manual transmission, it was hard to conceive how that package could possibly be improved upon.
That didn’t dissuade Steve Dinan, though. His S2 package fixed a car that wasn’t broken according to Car and Driver. Power was up to a massive 470 yet the car was still naturally aspirated. Bigger, better intake was met with bigger, better exhaust, and the whole package was kept up with bigger, better suspension and slowed down with bigger, better brakes. It was…well, bigger and better. 0-60 was dispatched in a tick over four seconds and it would do a standing quarter-mile in 12.7 seconds. These numbers won’t scare a Dodge Demon, granted, but are still really respectable today.
Of course, if “respectable” isn’t quite enough for you and you really need to surprise that Demon driver…

515 wheel horsepower equates to just over 600 crank horsepower, which is admittedly far less than the 808 produced by the Demon. But the M5 is some 400 lbs lighter than the Dodge, and catch the owner off guard and I’d like to think you stand a chance. As a bonus, though, when the road stops going straight (which often they do), the M5 is still a M5.
Condition here is excellent with a host of serious upgrades. The performance is met with a slew of carbon bits which grab your attention – you’ll be noticed in this menacing M. But this car has the chops to back up the look; other RK supercharged owners have recorded 0-60 times of 3.6 seconds and 0-100 times some 3 seconds faster than stock. That’s close to superbike fast. On its own, the RK supercharger kit runs around half the asking price of this car, uninstalled. That’s a pittance compared to the original $36,000 in Dinan modifications, mind you. And at the end of the day, underneath it all is a lovely M5 universally lauded as one of the best cars ever made.
If you’re into wild performance and outrageous looks, this is one serious package.
