    I thought ceramic engines are expensive?

    yes but relative to the total cost of a vehicle it isnt that much.
    no more expensive than equivalent hybrid vehicle

    Yes, ceramic engines are expensive to make and they crack easily. Ceramic engine is viably only if technology from the F-22 were to filter down to the lowly automobile industry. If I recall correctly, the F-22 has turbine blade that is ceramic in the outer layer and titanium compound matrix in the structural core. The idea is similar to Yonex's Armortec system.

    however, we dont need nasa grade ceramic for automotive use tho.
    also, there are more cars than jet planes so the cost would come down due to mass production.

    Pete,spending all that money for a low P turbo system isnt cost effective. I may come across sounding like anti turbo but not really. Turbos in the 70's and 80's were poor but had improved alot since then mainly from better materials (ceramic) and electronic (computer). I see lot of innovation in turbo and technology been filtering down to do-it-yourselfers now. Have u heard a remotely located TC system?

    I wouldn't go that far. Your mechanics probably only know small cars(aka ricers :p) GM does make good stuff if ur willing to pay for it. For example.

    http://www.gmpartsdirect.com/results.cfm?singlepart=1&partnumber=12498827

    not bad consider it is made to be abused. 720 hp, naturally aspirated, non fuel injected:)

    I wonder how much a racing engine with similar HP made by toyota and honda would cost. Found one site.

    LOL, copycat


    Super Power: AMG V8 proves there’s no replacing displacement
    DUTCH MANDEL and GREG KABLE
    Posted Date: 7/15/05
    In what Mercedes-Benz claims to be the most powerful, naturally aspirated eight-cylinder engine extant, the firm’s performance arm has developed a powerplant that will make it into virtually all its high-horsepower models.

    M-B claims the 6.2-liter V8 develops “a minimum” of 510 horsepower and 464 lb-ft of torque without a supercharger, and has 20 percent more torque than other free-breathing engines in class. Cars fitted with the engine will get a 6.3-liter badge.

    The engine and cylinder heads are high-strength aluminum and created with the latest metallurgical technology. Cylinder walls undergo a process to minimize friction, increase durability and add strength: The cylinder walls are twice as hard as conventional cast-iron liners.

    AMG developed the engine without Mer-cedes. It has a throaty exhaust note reminiscent of late-1960s Trans-Am cars. It not only sounds better than the supercharged 5.4-liter models it replaces, it is smaller and lighter—438 pounds vs. 485 pounds.

    AMG fitted a CLK DTM street racer with an engine for drive impressions. A bit of a shell game, on-site engineers privately agreed the car developed near 580 horsepower. Regardless, at first blush and full throttle the engine is a torque beast. That the 6.3 can fit in a current C-Class lends expectations that of the 24,000 engines AMG can build annually, they will be spread across the lineup. The 6.3 debuts at this fall’s Frankfurt show in an M-Class. It will be available in the States next year.

    honda engines are nice. small displacement but big in horsepower, all motor engines, i had a b18c integra type r engine tuned by spoon sports that pumps out 220hp:D

    wow, what did the dudes do to it? new camshafts, new chip, new ignition system, . . . etc.? No turbocharger & intercooler? And 220 hp is wheel horsepower?

    Horsepower doesn't mean anything by itself. A 600 bhp power car may be easily beaten by a 90 bhp car in an acceleration test. It is power-to weight ratio, OTHBE, that really counts. :D

    i think ur exaggerating the hp difference in making your point as u didnt specify the test duration. What good is beating a 600hp car for the first 0.25 sec?

    In performance cars power-to-weight ratio, AOTBE, is the key. A 90bhp car like in one model of the Lotus Elite, which weighs 600 kg, will out-accelerate a 600bhp car weighing 4,000 kg, on the straight and on a curve, for 1 minute or an hour, even when both cars have the same power-to-weight ratio. The heavier car is let down by it's massive rotating unsprung weight-huge tyres, brakes, wheels, etc. :D

    give me a break, who drive around a 4 tonnes car and has 'only' 600 hp?

    a better comparison should be with this foreign car eater AND IT'S A AFFORDABLE CAR.

    http://www.americancarfans.com/spyphotos.cfm/spyphotoid/6050701.001

    oh, btw, it weighs 1317 kg, power to weight ratio=0.46 vs your lotus of measly 0.15


    taneepak, if a car is 4000 kg, u need to up the hp to like this one :p

    Cooler, you have now come around and are talking sense, like "...power to weight ratio=0.46 vs your Lotus measly 0.15". See what I mean? :D

    i 'never had to' come around, it's in me all the time :p The problem with your comparison is that it has very limited application. Your lotus elite excel in low speed and/or short distance and/or for short duration, so what. There are many things in nature that can blow away both lotus elite and blue devil corvette. Take an ant, it has far more power than any cars compare to its weight. A dog flea, about the size of a pinhead, it can jump about 100 times its own height, a far greater leap than that possible for the multi-million dollar basketball player. However, can they do those feats when i sit on top of them? How about your lotus elite if a couple (american size) get on it with some golf equips or camping gears, watch the lotus elite performance go south, FAST :rolleyes: The only time when i refer the 90 hp lotus elite as 'fast', LOL

    Also, power to weight ratio alone isnt everything. There are many other design parameters that can enhance or degrade acceleration

    On it is right. they won't get IN it ! :p

    I thought he meant the Elise at first, but as the Elite is a 40 year old car I guess he really means the Elite.
    Dunno why pick the Elite though if you're after acceleration. Closest model to that described that i can see is the 1962 @ 660kg and 83bhp 0-60mph 11s (maybe there was a sportier version back in the day)
    why not go for the recent Exige @ 930kg 243bhp 0-60mph 3.9s
