blakep82 - 11/1/09 at 07:37 PM

ha ha, think we may need a little more info than that
we might need an actual question first


sillywil71 - 11/1/09 at 07:44 PM

soz i'm new to this,i was going to put engine in back but just thought it mite be easier to go for front mounted

Welcome to the madhouse
Do a search. There are a few people with bike engined mini projects. Not sure if any are front engined though.


alistairolsen - 11/1/09 at 07:52 PM

problem is you need the bike engine and box, and some form of final drive (diff)

Rear drive rear engine tends to be transeverse mounted and chain driven to a muffet diff.

Front engine rear drive like locost use a conventional diff nd mount the bearbox on the centreline with the diff offset.

to achieve front engine fwd is near on impossible due to finding room for the diff, chain drive, engine and box and keep it all low enough, and why bother

got r1 power unit ,so looks like rwd then

Hi,

Welcome. I am currently building a Mini with the engine in the front and rear wheel drive. Sound like you might need to do a bit of research. You can either go with a Live Rear Diff Set up or go for a Sierra Diff with you own home made independant rear suspension.

What engine are you going to use? Have you thought about how you are going to cut the tunnel and run the prop? How are you going to maintain ridgidity in the shell? How are you going to mod the front sub frame or are you going to make a custom one?

Sorry but these are just a few of things you will need to look at. A good place for some info is The Mini Forum. Also have a look on the Mac 1 website for Nick Mossop's Front Engine rear wheel drive Mini. There is an artical on it.

HTH.

It is not near impossible at all. I have seen several front engine rear wheel drive Mini's. Read above

Without trying to sound rude, if defo looks like you need to do a bit of research. A motorbike engine has it's own gearbox and there would be no way for you to get it working with a Mini gearbox.

What cage do you have? Got any pics of the Mini?

sillywil71 - 11/1/09 at 08:11 PM

yeah i have bike engine and box,mini gearbox i would't use its just the fact the shafts would slot in ,i was thinking chain drive diff somehow(remove gears from gearbox)i'll show pic's of mini soon


Omni - 11/1/09 at 08:16 PM

You will have to make you own front subframe for the Mini or buy the Pro Motive one. As suggested you best bet is to look at Pro Motive who make a front wheel drive Mini Kit

Here is a pic of what you would be talking about

More useful links to read, plenty of people putting Bike engines in FWD mini's.

Kawasaki ZZR1100-Powered FWD

Another company doing FWD R1 kits
http://www.miniexvo.com/

and best of all a build diary of an R1 FWD with lots of photos

Omni - 11/1/09 at 09:32 PM

Nice one iank

I didn't know about the Minexvo. Looks cool

That R1 Manx build page will be VERY useful for me too. Ta'

sillywil71 - 11/1/09 at 10:08 PM

yeah all links are very welcome just need the diy spec as everything mega money


iank - 12/1/09 at 02:25 PM

The build diary link I posted is to someone who's engineering the whole thing themselves so is the closest you'll get to a diy spec.

Basically you'll need the engine, a chain drive diff, driveshafts and a frame to hold engine, diff, suspension to the front of the car and in the correct positions.

The diff can be obtained from a number of sources or even made yourself if you have the facilities. Apart from the engine this is going to be the most expensive component.

Going to look something like these
http://www.locostbuilders.co.uk/viewthread.php?tid=101208

See http://www.westgarage.co.uk/forsale/kits/kit1.html
which shows one commercial source (IIRC the company is run by one of our members).

The frame is usually made by modifying the mini front subframe (as done by promotive), but can be a complete fabrication from steel tube if you prefer. For some reason the companies that make these commercially charge a lot more than you'd expect compared with kit car company chassis prices.

Lots of pictures of modifications needed for most engines over on 16v mini club and plenty of inspiration.
