STIs and EVOs define large power out of small engines, neither of which are european but i tend to agree that american engines seem much less efficient in the power to size ratio.

The engines used in Top Fuel Dragsters are basically 426 Hemi's, with 2-valves and push-rod driven. Although the ones used today are a solid block with no water cooling built-in and have a displacement of 500 cubic inches.well if by racing you mean revs limit then hydraulic lifters (or similar) are better. AFAIK F1 cars use a kind of double hydraulic lifter that pushes the valve open, and then pushes it closed under force. Valves in combination with a srping will have a maximum closing acceleration based on the weight of the valve, and the spring force. This maximum Acceleration wil determine how fast the valve can close, thereby limiting the maximum revs of the engine. I think F1 engines easily rev to 20K rpm. I was watching the Bahrain F1 GP last night and one of the team managers was saying to his driver "dont let the revs drop below 9000rpm". 9000!
I guess if you could transfer the technology (4 valve/cyl,turbo, variable cam timing, EFI, Elec ignition) from a small jap-type engine to a large US style one it would be insane. People who currently drive round in a 160kW 2litre 4cyl would be diving around in a 480kW (650hp) 6 litre V8. Death and carnage all round. Id like to dive one tho.
"Dang!"Wiki said:Power output of these engines is most likely somewhere between 6000 and 8000 horsepower (approximately 4500-6000 kilowatts).
This is calculated from performance as a dynamometer capable of measuring power output of these magnitudes has yet to be built.
This would suggest a torque output of 5100-6750 Nm (3760-4980 lb-ft) and also a brake mean effective pressure of 80-100 bar.
One of the good things about the new computers is the vehicle will help you diagnose the problem with trouble-codes. But my hands are definitely too Big to work on import cars. DXCapt.Marion said:f*ck technology. All that means is that A) its metric B) it has computers, so you can't work on it yourself, which makes it pointless. I'll take a 6 cylinder Cummins Diesel or a Ford Flathead-4 (Gasoline) or a Chrysler Flathead 6 230 (Cubic Inches, who cares about CCs? They just make you sound macho when its asian crap under the hood) any day with an honest-to-god mechanical fuel pump and an actual carburetor. I mean, who wants to buy all new sockets and wrenches, and get the mechanical engineering and sculpteral arts degree to actualy be able to work on your truck?
so will this
they will last longer and have less problems than their european rivals as well.
There was so much power to the rear wheels that the control arms could crack, Ford retro-fitted the cars with machined steel parts while the made new titanium parts iirc.Jeremy Clarkson bought one, but ended up selling it and getting a Gallardo Spyder because he never got from point A to point B with it - always broke down.
