A Perfect Engine

[pimento]

In my mind turbos are the devil's work.

Superchargers are ok, though.

Your mind might be a horrifying place.

Or something.

You've gone soft, Sr. Ferrer!

Something in the neighborhood of a 300 cid (4.9L) straight 6 sounds nice.
I guess I would think about it as a cross between the the BMW S54 and the AMC 4.0 with an alloy block. Something a little more revvy, powerful, light, and efficient than the Jeep four-oh, but maintaining its reliability and, to a lesser extent, torque (yes, I know the BMW has more torque, but I mean low-down grunt).
Throw in some fancy modern direct-injection system, the tech from Mazda's high-compression SkyActiv engines, individual throttle bodies, and Koenigsegg's upcoming camless valve actuation just for fun. Then, to bring things back to the good old days, attach glasspacks.

It is.

Probably.

You've gone soft, Sr. Ferrer!

I must be getting old... Death to sat-nav systems and automatic wipers!...

Ah no, all is well.

Or something.

In a completely unrelated note I'm for straight sixes too.

Straight sixes for the proverbial. Not sure about a 5 litre one though, might be hard to get them fat pistons moving quick enough.

I also think the turbo's the best but the prefect engine is not that one which is good when its new I think the prefect engine is that engine which is prefect and less of any fault after running a long period and it depends on usage and maintenance of engine.

We start building a 12.9 Liter straight six Euro 6 engine in the very near future. Pre-production is running now.

That's gotta be a truck engine

Sounds like fun, but doesn't seem like it'd meet F6's definition of 'revvy'.

[f6fhellcat13]

The pistons, conrods, and crankshaft are made from melted-down GTRs such that they can do miraculous things and/or they're all made from lazers.

EDIT: In my engine, not drakkie's. That said, I'm sure mahogany pistons would be nice.

It seems appropriate to mention this now.

Jep. Daf MX-13.

Not exactly. Optimum torque is achieved at about 1500 rpm, 510PS and +/- 2500 Nm. Perhaps not revvy but sure to propel your car forward rather fast If you ever race one of them trucks without load, it's surprisingly hard to beat!

Chevrolet swiped Occam's razor across many technological barriers of the mid 20th century, and tho most of their solutions were contrived to save money and reduce production costs, the resulting small block V-8 has proven to be one of the most versatile and useful dynamo's of the machine age.
Though not exotic, it was perfect for Chevrolet, as well as several dozen European exotics, untold race car builders and drivers, as well as Aunt Mildred, hot-rod Vinny, and who knows how many teen age boys first patch of rubber (double entendre intended)... and... and after 55+ years, it's basic architecture still moves sedans and exotics on public roads and over blistered tarmac.
Perfect? Not by a long shot, but right in so many ways.
