Ease of making a Triumph Rocket-3 Bike engine power a BMW Z4

[vlc]

imagine being asked to help fit a new m-bike engine from a 'triumph rocket III' into the engine bay of a new bmw-z4 to power it instead?
for i was wondering what all the problems would be in realising this.

first of, i reckon they'd be problems relating to fuel-timing an gear torque factors.
an i suppose if it couldnt easily be wraped around to directly power the rear axel, then maybe a chain could transfer the power thru the drivetrain - kind'a the way Cooper-F1 did it.

an all in the name of fun for people who like to think aloud

Given its shaft drive you wouldn't need the chain.

But the real problem would be power in relation to the Z4's existing engine, the weight benefit would be minimal

The bike weighs 320kg's DRY!!!!

i just had a thought about this...
for if you used this bikes engine instead of the usual powerplant, would its sound be noticly different from a typical roadsters engine, as while you are cruising down an motorway or 'a'-road?
* as i assume a 'car-engined' motorbike would probably sound different, then maybe an audio effect would occur either way?

for as i've never been in such a driving situation to note what difference there are i wouldnt know myself
* an i dont think a bike engined ariel atom or westfield xtr etc are comparable here, as there track-day racing orientation makes them less noise supressive than a volume car-makers more sound-insulated product.

ps- an does anybody know why lotus + mazda don't bother fitting a V6 into their roadsters?

if i was looking into doing an engine transplant for the Z4 it would be a V8! turn it into a german TVR lol.

Now all you need to fix is the looks!

And the first thing to change is to remove the Swastika from the radiator grill

Seems a bit of a strange choice to put Triumph rocket III engine that only develops 147lb/ft and 140bhp in such a relatively heavy car... especially as its less powerful than the lowest standard model.
