205 Car, Motorbike Engine

[Guest Dom]

Has anyone ever tried to put a bike engine into a 205?

 

Just wondered if it would be a very fast rwd car.

 

University leaves me with too much time to think!!

no. i was asking around about that long time ago, but the general idea

was that the car is too heavy (even when totally lightened) for the bike

engine to push it.

It's in norwegian. Someone put a motorbike engine with turbo in an old Ford Escort.

It's pretty fast! Guess a stripped 205 won't be any heavier than that Escort?

Its possible but its difficult. I'm not sure whether a 205 is too heavy (a stripped one is only 700kgs or less (without engine). Which is about 100kgs heavier then a bike engined westie. The issue is you'd have to put it in the back and sort out some kind of reverse and gear the bike engine down suitably. Something like a hayabusa engine would work but that'd need dry sumping and they're expensive engines anyway.

 

Anythings possible its just somethings are exremely improbable.

the problem with bike engines is the lack of torque. sure they have a lot of power high up the rev range, but the general rule is that you get 70-75lbft of torque per 1 litre engine size, so the car would be slow from a standing start and would need to be ragged everywhere, to make most use of it.

 

if you've seen videos of the bike engined escort, you'll see how sluggish it is from standstill, although it sounds the mutts nuts doing a flyby.

But pug 1.6GTi's have 99lbft of torque, and they don't rev to eleventy million rpm. Its more keeping the engine on the boil as they are very peaky.

Can somebody who speaks this language translate it for me as this is sooo coooollllll

The 1.3 rallye engine only puts out about 85 Ibs of torque.. 1 litre twins push out 75ibs or so.. and that'd easily be upped.. I don't think there'd be a problem with performance just getting the thing to fit!

there is a rear wheel drive rear engined suzuki hayabusa 205 that rallys i saw it this weekend at a 205 challenge round. Couldnt quite see how the drive was applied to the rear wheels think the gearbox was linked to a seperate diff it was covered up. One thing i did notice was the alternator was driven off the driveshaft!!!??? what happens when you stop? wierd idea i thought. Anyway it absoloutely flew it was a tarmac rally.

 

Just to let you know 205 1.6 challenge cars set quicker times than loads of cars plus an older type civic type-r rally car run by CCC magazine. (it was only fast in a straight line jap crap!)

Surely the problem with small capacity, high revving bike engines is that all the torque, along with the horsepower arrives very high in the rev range?

Its all very well revving a bike engine to 11'000rpm before you get its full 70 lb/ft of torque in a 200kg bike, but sticking it in a 700kg car wouldnt work very well.

[Guest TwoWheelTerror]

 

Look at the torque curves on these graphs..

[Guest Dom]

I was thinking of mounting it on a sierra front sub frame, as you would if you were going to install a cossie engine.

 

Probably still using a sierra back axle.

 

Good idea or not?

 

Was thinking of a Dimma kit on top or maybe seeing how far the ruggeri arches stuck out as i've been told a sierra back axle sticks out 3 in each side.

 

Not gonna start this project just thinking about it.

[Guest TwoWheelTerror]

Is it not possible to keep it FWD? There was that twin engined mini wasn't there..

[Guest mbl]

Do a search for Z-cars. They have done many bike engine conversions; latterly a single & double Yamaha R1 mini.

 

They sell diff conversions & reverse gears, as do quaiffe. You need rear wheel drive for traction.

 

A 205 is a bit too heavy. Their mini conversion is effectively a rear spaceframe replacement for the sub-frame. By using this & other light-weight parts, it should be possible to get the weight down to @ 500kgs. A Citroen AX would be a better proposition than the 205.

 

How about an Mi16 in the front & the rear? Reliable 320bhp & 4 wheel drive anyone??
