Re: Who says Americans can't build exotic supercars. --- If Chevrolet tried to recoup the cost of the Lotus R&D by adding it to the cost of the ZR-1, then that's the only accurate way of measuring whether the demand for the LT5 was strong enough to offset the cost. --- Actually, it isn't a good way to measure demand because the added price for the engine option doesn't accurately reflect the added cost of manufacturing. GM was just being greedy and lazy - something that isn't new when you're talking about their attitude toward the Corvette. --- These guys really thrash their cars, but they don't have enough money for alot of repairs. You see very few exotics in this type of competitition in the USA. The cars are mainly Japanese, German, and American. I haven't met anyone who blew an engine or anything like that. --- Then they're not really thrashing the cars that hard, are they? ;-> --- Apparently Mosler wanted this type of engine for the MT900, yet it's still very light and powerful. --- I'll bet you'll find that Mosler chose the engine because it was common, cheap and familiar. Plus, didn't a few of their employees come from GM? I'm not saying the LS6 was a bad choice for them, it was a perfectly logical one. I'm just saying that the car would be more impressive if the engine were more impressive. It wouldn't have been a big deal for them to design their own engine even using someone else's bits as a jumping-off point. Look at what Radical did with their Powertec V-8. http://www.radicalmotorsport.com/news_folder/v8stepsup/indexspec.php 400bhp from a 2.6 liter, 32-valve, quad-cam V-8 that weighs 203 lbs by itself or just over 300lbs with the gearbox as well. With the flat-plane crankshaft and a 10,000rpm redline, it must sound like the absolute business. Not bad for a shoestring budget. No reason why Mosler couldn't do something similar if they wanted to. The thing is, they probably want to concentrate on building the car and leave the engine to others. --- We're still not sure that any street engine is lighter AND more powerful, because none of us has determined whether or not TVR weighs their engines fully dressed. --- By "fully dressed", you mean the engine with all the things that would normally be attached to it (apart from the transmission) when installed in the car, right? I'll ask them at the TVR booth if I make it to the show this weekend. --- it's almost certainly taller and more thirsty. --- Why do you assume that?
