best engine?

[Nappa]

the 265 hemi 6pack

[nugget378]

VG30 kills the RB's, But for me it's the cleveland for the the impact it has had in this country.Just look at how the value of the 70's GT's is climbing daily

[Des]

I hate to admit it, but the small block Chev would have to be close, just out of sheer volumes and versitility. Kent series of motors for the same reason.
Technologically? BMW M3 6cyl., then new V10 BMW M5.
Race motor = DFV without doubt....though 426 Hemi would be a close second (turned into fuellers especially)....

186 Red Motor wins hands down ! ! !

or

The Saturn 5 rocket engine had more than 7 MILLION Foot/Pounds of Thrust...

I think it wins !

Less than half the displacement and over 50% more power.

F1 engines are unbelievable albeit they cost over a million dollars each.

Ahhh, yes, but as you say, F1 engines need 19-20,000 rpm to do it. the V8 5 litres only have just over 1/3rd the engine speed. It's very easy to make power with revs.

It's a bit hard to explain what I'm getting at, but obviously F1s have a greater specific power/displacement.

mk1 cortina lotus 1558cc twin side draft.lol :

[TEaaron]

I'd probably have to say the honda H22 Vtec, amazing amounts of power from a N/A 4cyl, 200hp+

[xf pano]

Have to say any of the Nissan RB series engines, specificaly the RB26dett godzilla. Although nothin beats the sounds of a hard revving clevo, you gotta give these rice engines respect for what they are.

Go on then, make your car rev that hard and put out 1000HP if it's so easy, and show me how to do it, cos that would be awesome

Everything I've read about it has been positive.......it's technically brilliant, heaps of grunt, forced MERCEDES to go forced Induction on all their top spec models to compete. A street production V10 that can REV to 8,250rpm and generate over 510 HP will always get my vote.............

It also won engine of the YEAR in 2005 as voted by a panel of International judges in the automotive Industry........It beat the Ferrari F430 !!!!!!!

It doesn't make over 510hp. It makes exactly 500hp @ 7750rpm. It also didn't force Mercedes-Benz to do anything. They came out with the Supercharged E55 in 2003 - two years before the M5 came out with the V10. The S/C E55 came about due to the inadequacy of the N/A engine that came before it, and their desire to produce the fastest vehicle in that class, which the S/C engine insured - the V10 M5 couldn't take it down.

Anyway, I take those International this and that awards with a grain of salt.

So, most impressive engine of the last 20 years? Hard call. There are many standout motors...

BMW F1 1.5 4cyl... they got 1500hp out of it. Not in race mode, it would tear itself apart, but still, that's 1000hp/litre. Normally I don't talk HP/Litre, but that is impressive.

Bugatti 8.0 Quad-Turbo DOHC 64-valve W16. To have an engine in such a light state of tune produce such power is phenominal. 736kW @ 6000rpm, 1250Nm @ 2200-5500rpm. Unlike every other supercar, it's not a whiz-bang rev machine with no torque until 329084903247863452343rpm that needs gears and revs to get going. It's my kind of setup. Any gear, and rpm, any time, bone-crunching power. And there's a hell of alot more left in it.

Porsche Air-Cooled Flat-Six, various forms. Absolutley gun engine. From the 176kW 2.7 Boxster to the killer 545kW 3.0 Twin Turbo 962 LeMans, they're a phenominal and unique engine.

Volkswagen 1.4litre 16-valve petrol inline-four. Ok, may seem odd, but bare with me. In a time of expensive petrol and uncertainty with future reserves, this engine is outstanding. It's a naturally aspirated petrol engine. No special technology. No variable this, electronic that. Just a 4v per cyl four-banger, which returns better fuel economy then Toyota's hybrid four-cyls and most diesel's. I rate it very highly.

There are so many more, I just can't decide...

The 2.4 V8's do not make close to 900hp. They make in the 700-750hp range at 19,000-21,000rpm.

The old 3.0 V10's had 900-950hp at 17,000-19,000rpm.

A V8 Supercar, limited to 7500rpm, makes close to 700hp.

It's impossible to compare race engines, because they are all limited by rules. At the moment the F1 engines utilise mainly RPM to make their power, whereas the Supercar's have capacity to fall back on.

In V8 Terms and car terms I would say Hemi V8 would be best.

In History & Application Terms Rolls Royce Merlin - They won the war for us.

Remembered in History Terms - V8 Chev Motor

In Australia close between The Holden 6 & the 308 V8. Repco V8 is another.

Oh, I forgot to mention, the CSRV (Coates Spherical Rotary Valve). Would do away with the inadequacy and inefficiency of the poppet valve design for good. I hope one of the big manufacturers takes the design on.
