V8, V10, V12
 

I have a question:

Which engine, either a V8, V10 or V12, would produce more power/torque, if all had the same displacement (for instance 5.5l), all had the same amount of valves per cylinder, all were naturally aspired, etc., etc.,...???

hmmm, im not totally sure but if they were all exactly the same except for the number of cylinders i think the V12 would produce the most power as it dosen't produce any (or very little) vibrations. I think the difference between the 3 would be very small though

I totally agree with mindgam3 about the fact that a V12 engine would get the most final power if the three of them have the same total volume of cilinders, although the V12 would get the slower to rev an engine once it has to push the largest number of cilinders, and the friction of the V12 is the higest of them as well, in addition, the fuel comsuption of the V12 will be the higest, once it has the engine has to push 12 cilinders itself.....for instance during the ninetees, ferrari was the only formula 1 top team which had the 12 cilinders engine, the ferrari was the best in racetrack which had long straight lines, such as Hockenheim, Monza, whereas in other racetracks where the straigh lines were shorter such as Silverstone, Imola,....ferrari was seriously struggling to keep up the mclaren, the williams.....

I am just guessing here - but I think a 346ci push rod V6/V8/V10/V12 (based on the GM LS6) that maintains the same stroke, cam profiles and fuel system would produce the following numbers:

346ci V6 - 315hp @ 5000rpm & 367lb/ft @ 3500rpm
346ci V8 - 408hp @ 6000rpm & 396lb/ft @ 6000rpm
346ci V10 - 476hp @ 6500rpm & 416lb/ft @ 5500rpm
346ci V12 - 517hp @ 7500rpm & 428lb/ft @ 5500rpm

But of course, these are just random guesses... :)

[edit]

What? No takers for this debate? ;)

They aren't all the same displacement though are they?

The same displacement - that is what " I think a 346ci push rod V6/V8/V10/V12" means... ;)

If they are all 346ci then they all have the same displacement :roll:

Here they are then (since no-one wants to join the frey.. ;))

Imagine an LS6 small block chevy that is able to have 6, 8, 10 or 12 cylinders - maintaining the same stroke and cam profile and fuel delivery.

The astute amongs you will notice that the intake and exhaust valves of the V12 are the same as the V8 - of course these would not be able fit in the cylinder bore.. but this is to keep all things equal aart from number of cylinders.

I will go back and adjust details to be closer to reality at some later time.

:D

nice little program you got there RC45 that is one hell of a V6 :wink:

RC: is that Chris' program you're using? What happened to that guy anyway?

When it comes to the engine producing most power, I think it would be the V12.

Uhm no.

Let's just say that his program was so far from reality it wasn't real.. :P

This a commercial dyno-simulator.

Well - considering that's what the math shows... ;) I am guessing that's a good call.. :P

"Go with the flow." I can't believe I said that. :shock:

Dude - you must had your fibre this morning - you seem to be in a chipper mood... ;)

lol, im asuming ci stands for cubic inches then?

We never use cubic inches over here so i just thought it was part of the engine name....

To be honest i wouldn't have thought the difference between them would be that great - not saying your estimates are wrong, but still

yes cubic inches
