twin engine
Just wondered if anyone had any ideas on putting two R1's into an MK..
Possably 4 wheel or 2 wheel drive.
for 4 wheel maybe use the hub's off of a XR4x4 ish....
thought it may be cheaper than trying to afford one of those transfer box's (£2000) plus....
So i thought i'd ask...you never know.

A transfer box to get both engines to the back wheels will be 5-10 times CHEAPER than the electronics you'll need to keep a 4wd car pointing in
the right direction, Z Cars 4WD cars have about £10-15k's worth of Motec engine management on it in order for it to handle remotely well.
Have a look at this Twin Westfield website, it is a friend of mine's car who converted it from a
car engine to twin bike using a Z-Cars transfer box, and just the conversion cost him about £12k. Drop him an email and chat about it if you are
seriously considering it, but personally I think its too much hassle and complication, and a large chunk of cash when you could get maybe 90% of the
performance (and probably be quicker round a track) with a 'busa.

Tiger do a twin engine car which uses very complicated electronics to control the engines which independently drive the front and rear wheels (if that
makes sense) because it is so complicated they will only do it as a turn key car and yes it costs a damn fortune - bloody quick though 0-60 in 2.8
secs!!!
The other complication is have two sequential gearboxes which have to be shifted in unison....
Another thought - is the MK big enough to take 2 engines ?
General drift is - on your budget - no hope sorry...

Yep, the Z-Cars and Tiger's cars are one and the same thing, Z-Cars built all the twins for Tiger. I agree about budgets, unless you've
got a £20k budget, any twin is likely gonna be out of reach.

It's intriguing though - always wondered how it handle through the bends if you had the engines in different gears? maybe you could just knock
down the front and then floor it through ?

I just wondered.......
way...way out of my price range.

its easier to do two sequential shifts off one lever then it is to do two normal gearboxes off one shift!
there was a twin engined golf in max power a while ago. not my copy of course...

It was a thought that popped into my head , wondering how much work would go into making one. didnt realise about the electrics..
i thought one diff at the front and a diff at the back one engine running each diff...who no's
It's only cos i still cant make up my mind what to do about the MK/FURY...ZX12/R1 ect.... and the more i try and figure it out the more piss@~
off i get...

That twin engined golf got a good whipping by a bog standard GSXR1000 on it's back wheel!!!!! see a couple of weeks old MCN.

I don't think a BEC would have "a" back wheel, and be able to pull wheelies

Hi Simon
agree with the back wheel but having just been out in MK's red rocket with Martin not to sure about the not pulling wheelies !!

well it just seemed a bit obvious that a bike is gonna be faster! if BECs are quick then bikes must be twice as quick minus the hang on factor!
is the golf like i remember reading it was, two nitroused supercharged VR6 engines? must weigh 1600kg then at least... so if he gets 500bhp from both
engines then a BEC only needs 166bhp to equal the ratios, and the BEC will handle much better due to the weight being nearer to the center. a heavy
engine at each end cant assist turn in!

Bike acceleration is not that much faster than the BEC up to 60mph, cos of getting down the power, they will leave you for dead after that though and
keep going long after you've run out of puff cos of the gearing.

If anyone needs convincing how quickly a bike accelerates, then watch
this video clip
Admittedly its a turbocharged Hayabusa, but up to 150mph or so a regular Busa wouldnt be far behind.

an amazing video but my computer didnt like it, caused a big crash when i tried to save it.
shocking how it goes from 150 to 180 after the wheelie ends!

I agree about the 140-180mph acceleration is absolutely phenominal.
It saved OK on my machine tho, I can e-mail it to you if your e-mail doesnt mind a 1.75Mb attachment.

I made it approx 0-200 in 20 sec, and reckon he could have done it much quicker if he kept the front wheel on the ground!!
I saw something on one of the Sat channels last weekend - standard GSXR1000 vs WLR/911 Turbo/Mercielago and numerous other "fast" cars on
the Silverstone "Indy" circuit.
Bike pissed over the lot. Closest was the WLR.
I think a diesel Rover 200 beat the M3

Sorry but on careful examination - I think the video is a fake....
If you watch the white lines on the road they just aren't going by fast enough and if you watch the left hand side of the road at about
(supposedly) 210 mph - well it looks more like 50mph.....

maybe its reading kph? i agree that the white lines don't quite seem to be moving quick enough as it were, unless the lines are longer and
further apart wherever it was filmed?

you can see the small kph guage inside the mph dial, reading 300 ish.
i think it is real, for two reasons. one, it is possible, and two, white lines can be hard to judge. who knows.
anyone seen the getaway in stockholm videos?

The turning on the left at >200 is the damning bit as I can see

I initially thought it was fake, but I changed my mind for several reasons.
Firstly as Joel mentioned, its perfectly feasible for a bike of this type to go as quick or quicker than this (a standard 'busa will do 0-140mph
or so in 10s), so why fake it?
Secondly, I think the scenery will always look slow because its not close to the roadside. Watch an on-board video of an F1 car doing 200mph+ at
somewhere like Monza and it will probably look very similar.
Also, I know it isnt accurate, but Ive just played it back frame by frame at a couple of different points. If you have a look at it frame by frame at
around 30mph or so, it takes approx 35 frames to go from the start of one white line to the start of the next one. At 220mph it takes between 4 and 5
frames, so the ratios approximately stack up (~7x faster speed, ~7x less frames)
cheers

After a bit of research on the net - I would still say its a fake....
If you trawl around the fast bike sites you will find that getting a Bike- even the 'mighty Busa' - to achieve over 220mph is nigh on
immpossible..
I found only 1 guy (on a news group) who claimed to be able to achieve 215+ and he was shot down in flames by other people who know far more than
me...
And sorry - the scenery may well be deceptive ... but that turning as you pass 220... nope

I don't claim to be any sort of an authority on bikes or high speeds for that matter, but to my eyes, that video looks pretty fishy. The left
turns, as protofj points out are just way too slow. And the other thing that makes me suspicious is how still the bike is, I'd expect there to
be a lot of shaking at over 220 Mph. It's not even as if it's on a pristine race track, just some random bit of road. It's very
difficult to tell when all you've got is a view of the road about the size of a postage stamp, and nothing in it for a lot of the time. Sorry to
sound boring, but I'd prefer it to be a fake, because if they really are doing over 200 down what appears to be a public road, then
they're idiots. There's next to no chance of you surving a car crash at that speed, I doubt if they'd be able to identify the body
of the motorcyclist.
