I can't remember how I worked out the tank weight...
I think it was 60L and that was how much that amount of water would be.

And I just used the heaviest battery optima have on their web site :)

Anyway, point there's not gonna be that much weight imcrease

petrol is around 1kg per liter and the tank wont be anymore than 20kg tops so you are looking at least 40kg more :tongue:

Yeah that will be fine its just like having an extra passenger... 40k is just over 6 stone so It's like 1/2 a passenger lol

What would really work well with an electric motor would be a CVT autobox but i can't think of any rwd gearbox's that you could use.

I can see where you are comming from with the whole plan though, its a shame you can't make it a plug in hybred, hook the motor up via another clutch to in input on the gearbox, then you would have a norman motor for driving and charging, and a motor and batteries for the short term

Yeah an auto box would be perfect, but I haven't found one that goes straight in... and I don't really like autos either! :P

Yeah I would love to have an engine and a motor but I don't think its really do-able :)

How's the conversion going? I'd love to see this thing going.

I was thinking the other day about it, and it struck me that the original mk1 Toyota Prius has an electric motor and auto box that might be perfect for you, if you can find one that's being broken.

I say might, because I have no idea really, I just thought that a prius powerplant would work great - people have started to shove yellowtops in prius's and running them as pure EV's, only switching to petrol for long journeys...

They are front wheel drive so the auto box would be useless for a start...

No entirely sure what other gearboxes they would fit into, but I'm not really even very keen on the engines.... Its like an electric motor that has a load of car parts (that can still go wrong like a car engine)

+ they are £350+ for an engine...

what about using the gearbox from a CVT fiesta, bolting the motor straight up to the input shaft, then weld the diff up and make that go straight to the t-box, might be a bit of a long arrangment but if you chop the bellhousing off then could work, and would be el cheapo, would mean no clutch, no need to change gear so would suit the constant power of the electric motor

Whoops. I assumed they were rwd, because the little computer display inside shows an arrow pointing along what I assumed was the drivetrain toward the back wheels when you're on motor power. I havn't driven one, just seen the display.

Still, it's a motor that's powerful enough to shove along a car at decent speeds, can the motor be torn out and used? Might save you a few quid if the specs of it are similar to the one you're looking at already. Electric motors should last vastly longer than the rest of the car, so you might be able to pick one up for a decent saving, then bolt it up to the flywheel, as you were talking about before.
