Question on converting to bike engine

Hi guys,

My Dutton currently weights in at about 650kg with Pinto and type 9 box. I reckon coverting to a bike engine should drop it to about 550kg. Is this too heavy for a bike engined car? It will be being built on a budget so the engine is more likely to be something along the lines of a fzr1100 engine.

Also does anyone know the specs for this engine - bhp, torque and weight.

Cheers

550kgs is a bit on the heavy side, but it should be OK. Most BECs weigh around 420-500kgs so 550 isnt that far away I guess, just dont expect 0-60 in 4s or anything unless you go for a busa
Not sure on the engine, are you sure you dont mean ZZR1100, or FZR1000?

My error. I did mean ZZR1100. I wasnt expecting 0-60 in 4s lol, although i'd be quite happy to get to 60 in 6s or slightly less. As long as its worth ditching the pinto for.

The 4 engines we were thinking that may do and be cheap enough are:

Kawasaki ZZR1100
Kawasaki ZX10
Yamaha FZR1000
Honda CBR1000

Out of those Id say CBR1000, they seem to be bulletproof and you can pick them up for peanuts. The ZZR's seem to hold a slight premium (or did) because Radical used em in their early cars so the racers used to snap em up.

But I have an FZR1000 for sale

£500 with all electrics and exhaust - will throw in frame and V5..

But a CBR would be the one I'd choose out of them all.

A 2ltr pinto in a 650kg car with twin carbs and fast cam should see you very low 6's or even high 5's.

Yeah Id agree the CBR 1000 engine is totally the way to go

You should be able to pick up a CBR 1000 engine for £400 at the most - 135bhp and fairly torquey at 78 ftlbs at 8500 rpm

Heavier than blades apparently - my mates lift-o-meter rates it at about 70 kgs!

Its a good bet in all seriousness - but I wouldnt rule out any of the kawasaki engines - Honda gearchanges are notoriously a bit harsh and my old suzuki Gs500 had a silky smooth change compared to my CBR 600 which is a bit jerky to be honest - maybe some of the other engine/gearbox combos offer a better change?

Good luck!

weight

Only 100Kgs saving!!

i think its impossible...

my bike engine i can lift it myself..
soow it will weight 70Kgs... (or less not that powerfull)

with tho persons i did the installing of it.

a pinto engine with clutch flywheel, gear etc..

wouldn't it weight all togethher 220Kgs??

30 for the gearbox and clutch and 190 for the cast iron engine ??

that would be a saving of 150Kgs

With that much weight and so little flywheel effect, wouldn't around-town drivability suck? The Dutton (I assume that's it in the avatar) doesn't appear made for the track, so around town would seem to be the priority.

Any feedback?

Mucho slippage of the clutch round town i think.

Pinto doesnt weigh that much does it, i thought it was about 120kgs

From what i've found out a Pinto and gearbox, without bell housing, starter, fluids, gear stick, clutch weighs 168kgs

The Melos doesnt look like it was made for the track, but it uses the same chassis as the Phaeton which looks a bit more like a 7. Plus its having suspension overhaul and bigger brakes.

The plan is to do quite a lot of track days in it and it only comes out at weekends.

So, CBR1000 sounds good. What will I need for the conversion?

Driveability with CBR1000 is excellent, extremely flexible, trick is to get the clutch weight and travel correct. The engine itself is extremely tractable and forgiving, throttle response is instant. Having been the owner of a 2.0L Pinto engined F27 I'd say 'get on with it', the Pinto is a boat anchor, and deserves to be where anchors normally reside. Oh and the sound of a CBR thou' on a decent exhaust revving to 10,500 is pretty good too. Any help you want just shout.

The Melos my be build on the latter Dutton ladder frame chassis design but it is still good fun to drive, especially if all you have to compare it against is a Euro-box sallon or hatch.

Not the perfect track weapon but will still put a smile on the face for relatively minimal cash, even compared to the average Locost build!!

Anyway, it doesn't matter how good a red, blue and yellow paint job you did on a Locost it wouldn't look like Noddy's car, which makes the Melos cool in it's own right!!!

Roger - that's the first time I've heard "Cool" and "Noddy" together in the same sentence
