open wheeler with roadcar engine

[sliderule]

Can anyone please tell me how reliable would be to put lets say an unmodified Ferrari 599 engine and transaxle in an open wheel monocoque and run it around for 1 hour?

Stressed member or unstressed?

Idle it or race it?

unstressed, racing it.

If you provide adequate cooling for oil and water then why should reliabilty be an issue?
I'd also look at the sump baffling to keep oil pressure up as an openwheeler would be producing far more g-forces.

Now what about a race of openwheeled chassis with roadcar engines and transmissions. For example imagine mating an engine and transmission of a Ferrari 599 GTB Fiorano to an openwheeled chassis and racing it to a similar chassis with the engine and transmission of a BMW M6. There you could also have one of the cars opting for the engine and transmission of a Mercedes SL 55 AMG and another using the Lamborghini Murcielago's powertrain. You understand where I am coming from. Basically have the powertrains from cars like the 7 liter Corvette, the twin turbo 911 Porsche, the new Audi v-10 complete in similar if not identical open wheel carbonfiber monocoque chassis and see how well they do against one another. Would it work and would enthusiasts be interested?

Only one of those cars really has an appropriate transmission, that being the Murcielago.

I can see where you are coming from though, but I think most people would choose the Porsche engine depending on the tyre size regulations

sounds cool but those engines were desinged with a certain chassis in mind so they will be less than optimal in the open wheeler

and where do you plan to find these engines

About the transmission I would think the Ferrari 599 GTB Fiorano would probably have a suitable one however I do wonder about the others. Concerning tyre size and regulations I thought of big fat low profile slicks on large diameter rims. One may think I am nuts but I would like to think about these fictional cars with no aerodynamic devices, basically no front or rear wings. Let them be all about mechanical grip.

I doubt the 599 gearbox would work effectively - you'd still need a diff after the output shaft. This would make the drivetrain so long that the wheelbase would suffer. Sure it would work but it would be engineering suicide

I suppose the 911 gearbox might work too if you swung it around and turned the diff upside down.

I like daydreaming too

True these engines are best suited for roadcars however it still would be interesting to find out which ones do best in such an agressive racing environment. About finding these engines and actually racing them is the essence of why it is only an idea I have. However I would like to know about the reality of it in mechanical terms and not so much about the reality of its financial terms.

But doesn't the Ferrari 599 have a transaxle at the rear much like the Corvette Z06?

i belive teh vette has a regular old pumpkin back there no transaxel unless you mean the c65 in that case i have no clue

to often you cant have one without the other

you can make any thing fast alls it takes is money

same way with bolt in engine swaps as long as you have a 3 axis cnc a big hammer a torch and a big smelly guy to do the tweaking they are a peice of cake

The old 550/575 did but I understand they have reverted to a normal transmission now.

Even so, it wouldn't be as space efficient as a transaxle that bolts directly to the engine as there will be a flanged section between each.

[sliderule]

Lets say the transaxle was made as a standard part just like the chassis and the the different manufacturers engines were bolt on parts to the package to see how well they fare against one another. Would it be interesting, and how fast would they go? Would they be faster than F-3 cars?
