IND Green Hell 600HP BMW M3 Coupe

So this thing has no hood? Wow, for a German tuning company, this is a rat-and-stick approach, don’t you think? Well, in any case, it is difficult to argue with the BMW M3 coupe that has been squeezed (swallowed) to 600 horsepower. In any case, the German tuning company in question is called IND, and they like exaggerated car names and a lot of power.

IND Distribution says they specialize in ‘primo’ BMW M3s (Primo, now there’s a word I haven’t heard in a long while). In the past they’ve built such modded up M3s as the Dakar Yellow E92, Silverstone II E93 drop-top, another E92 the called Red Death, and a carbon-fiber-roofed E90 M3 sedan.

Their latest is, yet again, based on a BMW E92 M3 coupe, and showing the same restraint and good judgment that has got them to where they are, they’re calling this one the Green Hell. It has something to do with the Nürburgring. Or was “inspired” by it. Or it just sounded cool. Or something. Sure.

The latest IND-massaged M3 is supposed to be a track car that is also fully street legal. How much it’s overall drivability has been effected I can’t say, but who knows, it might be able to serve both its track masters, and the rigors of daily driving. The Green Hell’s 4.0 liter plant has been improved via an ESS VT2-600 supercharger setup, selected for its abundant power. The ESS VT2-600 supercharger puts out 6.5 psi of boost and generates 600 horsepower.

Other details were not as forthcoming from IND, other than this: The blower breathes through a Challenge X-Pipe and one-off Eisenmann Inconel exhaust system.

Inconel? That’s an interesting material to use. I had actually played around with that stuff before. Its full name is Inconel-X, and it’s a nickel-steel alloy that was first used on the X-15 rocket plane back in the 1960s. It’s highly heat resistant (which you would expect), but it’s not exactly light either. It’s also a real bitch to work with. I gave a plate of it to my dad, a tool and die maker, once. It was about the size of a dollar bill and about a 16th of an inch thick.

“Here. See what you can do with this,” I said handing it to him.

He turned it over in his hands twice, and started picking at the edge with his thumbnail. “Huh. Nickel? It’s got nickel in it ... but it’s too heavy.” Now curious, he turned away to his workbench and set it down, returning to refinishing that steering joint for his Sunbeam.

I saw him a couple of days later.

“Jeez, what WAS that stuff?” he asked.

“Oh that plate? It’s this stuff called Inconel-X. You have fun with it?”

“Fun?! Ron and I burned through two drill bits just trying to punch a hole in it! The second one was tungsten carbide! Where on Earth did you get it?”

“Boeing surplus. It’s a nickel-steel alloy that’s real heat resistant. They used on the X-15. Boeing uses it for a bunch of different stuff. I know you can weld it.”

“Yeah? You can also bend it,” he said, holding it up, grinning, having rendered it into a square section. “Makes a good paperweight for drawings.”
