    One of the desirable qualities in a track car is the need for the engine to stand up to many hours of abuse. For this, a big, "lazy" engine that is putting out less power than it could is a good thing. A big, naturally aspirated V8 or V10 with relatively low compression, low rpm, and low stress will last longer than a finely tuned tiny engine that relies on high rpm and/or high boost to generate power. How many of the Japanese or German sports cars can spend 40-60 minutes on a track without overheating? (even the so-called "track specific" models?)

    Viper engines are lazy engines. They were designed that way on purpose. Put a supercharger on them, and you get 800hp. Put twin turbos on them, and you get 1000+ hp. But in stock form, there is a lot of unused potential that translates into track durability. Factory Vipers dominated endurance racing because of their big lazy engines.

    Having a big, flat torque curve is another benefit of a big lazy engine.

    So, I guess we have a difference of opinion regarding engine size and track use. I'm definitely a believer that a Viper or a Corvette make great track platforms in no small part because they have bigger engines.



    The ZR1 is a "straight line beast?" There are only a very few cars that can keep up with a ZR1 on a track. I would not characterize it as a "straight line" car.

    The Chevy small-block V8 as found in the Corvette is already more efficient, powerful, smaller, and lighter than engines produced by those guys. I'm not sure what they'd do to improve it.

    It's both a straight line monster and track car. I still think the interior is up for a refresh, it still look straight out of the 90's. With the new Corvette looming, I guess they won't be upgrading it for this current body style.

    The corvette has a 6.2V8 and 430hp, the old 6.2 V8 from AMG had 525hp, so I don't know about that. I would still like to see what they could do with an 8.3 in the Viper.

    I only see the 6.3 with 518hp NA V8, is that the one you meant?

    Thanks, stupid Benz website and it's layout makes it difficult to browse. The SLS with 570hp is just nasty. Just saw the report on the new SL65 with V12 twin turbo with 621hp & 738lb-ft of torque. Too bad the car doesn't look that good.

    You can buy a 650 HP LS7 for $18.5K:

    http://www.enginefactory.com/ls7_650hpfi.htm

    That is for a brand new engine, lightly modified from the factory. There are more powerful versions for slightly more money. $19.5K gets you 700 HP, normally aspirated.

    You'd have better traction if the Cayman were AWD. ;)

    It's roadster season again, so I traded the Fiat 500 in on a Boxster S. :)

    987? Or ordered the new one?

    Been enjoying the Z4 the past few days that's been warm here in Cali.
