Right this is a Serious possibility for me over the winter with my toy

If i was running a car with an engine in the front, and an engine in the back, how well balanced would each engine have to be with each other, ie BHP / Torque, so not to try and rip the car apart or one engine 'carry' the other?

Also with the gear linkage been permanantly joined together, ie both boxes select gears at the same time, if i was to only run ONE engine, could a line lock on each hydraulic clutch pipe be sufficient to keep the un driven engine's clutch dipped? or would this kill the release bearing in no time

Would it be possible to map each engine on the rollers to within say 5bhp of each other

Cheers for any info on any of the above and anything i may have overlooked

Great as an engineering show case but other than that I can't see the point!

Just build one high powered engine - less hassle, cheaper and lighter!

 

Just doing it cos,(a) I can, (b)I like pissin around, (c) I like a challenge and (d) I fancy a laugh. Plus I have a rear engine Mk1 fiesta already so one up the front aint too much trouble

Bri.

 

Looked into this myself a few times as ive got a huge interest regarding twin engined machines.

A feature a while ago about the twin engined mk1 golf addressed the problem which you spoke of regarding one engine 'carrying' the other. The owner stated that it's a bit like 2 blokes pushing a car, 1 strong bloke, 1 smaller bloke. Although one bloke is doing more work than the other its still better than just the one

Will DEFO be building a car like this when i finish my Zetec Turbo project properly.

 

Also do the engines have to be balanced together, or could the rear one be a bit more punchy, as i think a 50 / 50 power split could make for some fun country lane cornering

Bri.

 

Just build one good engine

 

its illegal to have two engines on and linked at the same time out on the public road, you would only be able to use it legally on track! just so you kno...

 

Your missing the point I have had enough of the NORM, At the end of the day if I think its shite, I have a complete engine and management set up to sell

Any one got any positive advice

Bri.

 

and its a serious feat of engineering to do it successfully and reliably, but if ur bored, then fuck it, do it!

 

i am thinking of putting another 172 clio engine in my clio
4 wheel drive twin engine 344 bhp n/a
should be fun
and i am lucky as one of mates is ian from dub sport who built the twin engined golf he said
you can put a lawnmower engine in the back and a jet in the front it doesent matter
as for the clio pros
4 wheel drive
independant suspension all round
light and quick
and with me in the middle well balanced
just do it at the end of the day think of all the rust you will be cuting out

 

*Bri.4.b.Cos*

Have you been drinking again?

FFS Bri, buy a house.

 

it's just like a 4x4 system with different torque split

 

Also if one engine packed in would you still be able to travel home on the other engine?

 

What's the point?

Apart from the engineering involved which is obviously very cool, where's the purpose?

Doesn't make it any quicker up the 1/4, chassis balance will be all over the shop, so would make a terrible track car, and for the road, it's entirely pointless.

Suppose it depends what you build your car for. Do you build it to enjoy it on the road/track, or do you build it to park up at a show so people can go "oooh, that bloke put two engines in his car"?

 

I TOTALLY agree with Rich

 

mates doing this to a corsa with 2 xe turbo'd engines in and both big power all because my shonky escort beat his V6 corsa

 

Bri

I think your right “Why Not”, even though it may be pointless over a single engined high powered car and handle strange, the hard work has all been done when putting the engine in the rear so putting one in the front will be easy.

The hard bits will be balancing them, which may not be a problem but the gear ratios and final drive will have to be the same. Also the gear linkage would be a pain, you could always make it so you can put them in neutral then have a quick disconnect pin to leave one in neutral so the other one does the work rather than locking the clutch.

I would check up on the legal bit about running two engines, what about hybrid electric/petrol cars do they only run one at a time?

Jim

 

Well iam with Bri on this ill defo be building one in the future as thew twin engined concept truly fascinates me.

I wouldnt use it as a track car, only fast road and drag strip, and if i recall correctly the twin engined renault 5 of Ian Nixon ran in the 11s quite happily. Plenty more room for improvement with slicks etc...

 

u lanky fooking nutta

go for it

 

id rather build a space frame with an engine, then drop a wafer thin fiesta (or similar) shell over the top of the space framing.

 

Like my Series 2... Only prob, I havent fully decided what engine to drop in yet?!

 

Maybe true but then were all different
I mean there is not point in a lot of things
Climbing Mount Everest for starters whats all that about

My house looked quite nice all painted magnolia ,but it sure as hell was not for me

 

Is yours the red one with the lancia engine?

 

they run both at once under some circumstances. but as one is an electric motor, perhaps it is not classed as an 'engine'

 

If both engines drive through the same final drive train, it's legal, it's do with not allowing one engine to stall and lock up one axle if both axles are independantly driven.
An electric motor will freewheel when not powered.

.

 

Nope

I am building the car for ME and the point is I fancy some thing different

I might just do that

Thats the one

Thats my thinking, aint much work to put it back to how it was either

If this is the case how was John Coopers famous twin-engined, 4X4 "twini-Mini" Cooper in which he nearly lost his life after a serious crash on the Kingston bypass get declared as being road legal in 1967 ?

The car at the following URL is a twin engined Mini and has a number plate and appropiate tax disk displayed in the pictures

http://www.minimania.com/web/SCatago...4/ArticleV.cfm

I personally know a twini-mini which has valid MOT, TAX and insurance and driven on the public highway

Z-Cars actually sell twin engined converted cars

http://www.zcars.org.uk/ultima/index.htm

 

Never knew about that Mini. Quite cool if a bit pointless.

Can you tell me some details on the other Twin Mini please?

 

Im Building a Twin engine 106 at this very moment.

 

Good luck to you mate dont listen to the haters

Do'n forget to put it in the resto section

Bri.

 

L E G E N D



.....but put a propper engine in it

 

Like????

Bri.

 

my mastes dad had a twin engined renrot 5(europarts)
was wicked fun in a straight line but the handling was a bit
due to weight being everywhere


all depends on wot for track or strip

 

The twini-mini is not a hard conversion as the gearbox is mounted under the block and the subframes for the twini's you can buy off the shelf.

The entire mini range has been twini at some point including the mini moke
http://www.minimarcos.org.uk/altpics/twini.html

The twini has even been documented in manuals



There's even a twini's about that runs 1480cc metro turbo lumps and goes very well

 

It's not a case of being a hater - it's simple practical experience.

Why would you want to be different if it doesn't work as well for the purpose intended? Hence my question, what do you intend to use it for?

Obviously it's going to be for you as you own it, but consider this.

If you built a twin RST engined Fiesta for example, and intended to use it solely for track work, would it not be a bit pointless if a single engined car was faster and better handling?

 

PON/PORKIE:

why do we do anything?

to be different thats why.

pon, your saph was a monster, just a shame it was never finished... that was far from the norm

porkie, your 3dr is certainly not the usual either...

specially that fucking great spec r tank you got in there now lol


my 3dr... its a 1.6GL, im trying to do something different with it... not to everyones taste i know, but fuck it... why be a follower?

 

Well the car as it is when i fit the new zetec motor is going to be used on track a few times, however the handeling needs sorthing first, its like cornering with a snaking tralor on the rear

When the winter comes i am concidering putting another engine in the front, just to see what its like. And i will see at this point how it goes and corners etc, then make a descision as to wether i keep it as it is for a while or put the motor into a XR2 or similar and sell it on

Bri.

 

Skyline RB26 (with a stroker kit...), GT42R, stick a Supra diff at the back...

That should get rid of you
