Interesting videos. The Renntech CLK goes on to fry its ECU on the track, the first car to drop out. A cautionary tale for those who belief that expensive mods always improve the breed.

Not sure if it's just rumor or not, but I heard that RennTech CLK cost almost as much as an SLR.

That would be a stretch, given the extravagent pricing of the SLR. But I'm sure all those mods would have cost more than the base car.

One Lap 2001
George Samuels Captures the Thrill of Victory and the Agony of Defeat in 2001

THE JOY OF ONE LAP

We were two, weary men in the autumn of our lives, searching, as men have done through the long, long years, for the Joy.

And the Joy seemed to be in short supply this year. Many of the older, more experienced competitors shared with one another a vague dissatisfaction. Often, they said that this would be their last year. Over and over, I heard the question, "Why are we doing this?" I always responded, "For the joy of it." They looked at me as though I were some poor, idiot child that an unkind fate had left on their doorstep. Rick Potter, my co-driver, was particularly quick to give me that look. I understood what he-and they--felt. This year seemed different. The pressure to win was higher. The light-hearted foolishness was less. Life seemed to be reduced to some humdrum sum: a number totaling the worries and wounds. As we drove through many of the long dark nights, pondered, "How is it that we are come to this: that we cannot find the Joy?"

On Friday, May 4th, we had the great pleasure of seeing all the friends from last year, comparing notes and catching up with one another's doings. We added the required decals to our cars and ran them through tech inspection, then wandered through the parking lot looking to see what the New Year had brought us. There were wonders and delights. Dan Kary had returned with a wonder, a Renntech-built Mercedes with a reputed half-million dollar price tag. It had devices and techno-magic that most of us had never dreamed of, let alone actually possessed. Kary told us that it had produced 700 lb./ft. of torque at 2500 rpm on the dyno. It had a fully adjustable suspension that could be reconfigured on the fly from the driver's seat. It had aerodynamic devices that would have been more at home at Bonneville. It was an automotive technological shrine. Aaron Quine and Bill Hoskins, a pair of Lap Puppies, showed up with a delight, a Corvette GSR featuring the best of 1963 technology. It was a real, hairy-chested, balls-to-the-wall, we-are-not-constrained-by-common-sense sports car that delighted everyone with its sheer effrontery. No top, no windows, no creature comforts of any kind; it was just enough chassis to hold an engine and keep four wheels upright. I liked it.

.....another snippet from the same article:

Not a bad beginning--certainly not as bad as the vaunted Renntech ubervagen. In spite of having been clocked at 185 mph on the back straight (according to Brock Yates, Jr.), its techno-wonders had betrayed it. The paddle-shifter actuated transmission downshifted to first in the middle of turns with predictably unpleasant results. It was withdrawn from the event.

Thanks, Chapster, as usual you are a font of knowledge!

510 HP and 520 TQ sounds low for a six litre version of our engine running 10 pounds of boost. But 700 pounds TQ quoted in the other article sounds too high - maybe we're talking about two different vehicles? I doubt the driver in the Car and Driver one would have been able to adjust the Koni suspension on the fly.

Anyway, whichever car(s), what a beast! On its consolation tracking it almost beat the RX-7;s lap time (albeit in better conditions) - and that Mazda beat the Corvette by 3 seconds, only losing the competition becuase the rules were rigged in favor of big power down the straight ... something which this CLK should have been able to deliver in spades.

So it could have, should have won the whole damn thing.
