Just thought of another one.. the new v8 in the upcoming M3. Word on the street is that it another version of the modular V10 in the current M5 but with 2 pots lopped off the back.. if this is the case, it will make 298kw and 416Nm from 4 Litres. Otherwise, all the same fruit as the V10, DOHC, Aluminium/Silicon block (no need for cylinder liners..) and variable timing, all with a redline of 8000rpm. Nice.
Oh, and all hail the V8 Hemi in the Chrysler 300C. It has 'Variable Displacement' as every big capacity engine should. It shuts down 2 or 4 cylinders when the demands on the engine are low to save fuel and cut emissions.. one of the few 8s to meet and exceed euro 4 emissions standards.
the new v8 hemi is in all the new aussie delivered jeeps also. Very very fast engines, they took the record for fastest mass production 4x4 by plonking in that 5.7L v8. And to top that they Chrysler are now about to plonk in an even bigger engine, 6.1L V8.
Let me start by saying that these threads are common across lots of forums and in my experience are completely random and stupid guesses based mostly on hearsay and marketting except in the rare instance of a well-informed engineer (eg. not me) stumbling in and giving real hard information. So back to the pointless guesses and hearsay, I'd like to put forward the cosworth DFV (and its successors) for excellent packaging, its leading power output for its time and for sheer racing pedigree, no other motor comes close.
Why do people say SL55 AMG engine?
I LOOOOOOOOOOOVE those cars and yes they make amazing power but how is it better than an M5 4.9L V8? Ok less power but it has no boost. Not to mention mercs have SOHC 3 valve engines. I am sure they are great but I pick BMW still
You've gotta say who it's awarded by and I would bet on it being best American engine, but look at all the other crap they produce.Quote:

Now that's a logical choice, no cut corners or design compromises. There's a good reason why BMW won engine of the year with the V10. Wouldn't mind betting M3 V8 may follow suit. :DQuote:

pure muscle the 351 cleveland, with a fat carb. its not rocket science but raw power.
But does raw power make a good engine? I don't think it does.. any engine can make shitloads of power but what makes an engine great is whether it can make it using a minimum of fuel, if it is well packaged and if it is reliable. I would hazard a guess that the 351 was a rather thirsty engine, by today's standards, it isn't very well packaged and they're about as reliable as a weather forecast.. Many new V8s are amazing pieces of kit which shouldn't be dismissed as an attempt to turn old school into something like a twin cam 4... just my opinion.
Road and track... they also gave the s2000 over the Z.Quote:

do you by any chance have a pic of the exhaust turbo manifold for this engine?
