Never Enough: Dinan to shoehorn 628-hp V10 into BMW M3 - Autoblog
Dinan strokes the M5/M6's V10 to 5.7-liters, 628 hp - Autoblog

The hefty price tag and somewhat limited availability of the BMW M5 and M6 ensures that only a select few get behind the wheel of a 500 HP masterpiece. That kind of power, coupled with the razor-sharp performance of a precision-tuned BMW suspension make for a driving experience rivaled by few automobiles on our planet. No matter how great these M-tuned Bimmers are, however, there are some who strive for more. That's why companies like Dinan are around to transform the sublime into the ridiculous.

If you have a passion for power and an additional $40,000 in your budget, Dinan can transform your "ordinary" M5/M6 into a race-ready athlete with the heart of the champion. For your 40-large, Dinan will take the 5.0L V10 that powers the "standard" M5/M6 and bore and stroke it to 5.7 liters. The end result is a legitimate road beast that cranks out 628 hp and 482 lb-ft. The additional hp under the bonnet of the Dinan M's still revs freely to 8100 RPM, and much of the torque is available as low as 3000 RPM. To keep Dinan's 5.7L flamethrower breathing freely, the engine tuner added high flow Intake/air mass meter assemblies, high flow throttle bodies, free flow mufflers and a racing exhaust. Sure the extra $40k can almost buy you a spare 335i, but if you want to make your M5/M6 even more exclusive, Dinan's solution is as good as any.

Ever meet one of those parents who are never satisfied no matter how well their kids do? The child comes home with a 98% on a school exam and the parent asks "How'd you lose two percent?" Dinan is one of those parents. But instead of overstressed children, Dinan produces overachieving performance automobiles.

Take, for example, the latest M3, which BMW unveiled with a V8 derived from the award-winning 5-liter V10 found in the M5 and M6. The eight replaced the inline-six on the previous model, but instead of remaining content to say "good job on the extra two cylinders", Dinan asks what happened to the extra two from the V10. Not that they would have been happy with the V10, either. On that, Dinan pushed and pushed, boring and stroking out the engine's ten cylinders until they got it up to 5.7 liters and 628 horsepower. Pretty sick, but saddled with the heft of a BMW 5 or 6 Series, Dinan couldn't help but ask what would happen to its pride and joy in a more suitable setting. Word has it now that Dinan is preparing to shoehorn in its 628-hp concoction into the M3's engine bay. Thankfully they'll be lightening it up a little after that, removing some of the bulk from the front end in order to keep the weight balance in check. We can't wait to see what it can achieve.

if BMW wasn't so goddam common on the streets and I were just starting to shop for a car now (i.e. have not sunk six figures into my Skyline), I'd be looking mighty hard at Dinan's offerings.

But true to my retro tastes, I would be asking for big power shoehorned into the E30 M3 chassis. The E92 has been Bangle-ized.

Hartge did it first with the E49 M3 and the M5 V8 but also did the M5 V10 into the E93 M3 first!
