Citroen used to offer twin engined cars, but I think it was just an effort to make a Citroen that would keep going until you got where you intended.

How far north? Yorkshire, Scotland or the North Pole? A properly designed cage inside a unibody can be stronger and lighter than a full tubular space frame.

Cool. My father was born in York and my mother was born in Huddersfield 89 years ago but I was made in Georgia USA after the war. I spent my summers in England for my first 16 years. I have superior northen blood flowing in my veins yet I'm a southerner and hate the yankees who live in the north because I am now a rebel. I still live by the Yorkshireman's Creed. Did you get all that?

I’m in the middle of building a twin engine track car at the moment, it’s not finished yet but once it is I’ll add details on handling and the drivability.

Details of the build here

http://www.clubgti.c...ad.php?t=116662

I'm starting the process of having someone investigate how to link the 2 engines now. It will be an independent device that will allow the rear engine to have up to an extra 1000 rpm more at any given time but the front to never overspeed the rear. I will keep you informed of its progress, hopefully just a simple electronic rev limiter based on rpm differential.

My (later) project will have 3200cc (imagine 2x Toyota 4age units) and about 250hp but will keep it light.

70's - 80's Subaru discbrake calipers are 1 option should you require cheap calipers with handbrake.

And my 1 idea for your engine balance ...

Take 1 tube with a form of piston in the middle that covers a blow off hole (or 2).

Piston located centrally by a spring at each end.

At each end run a pipe from the 2 engines inlet manifolds.

When 1 engine develops more boost pressure than the other, it will move the piston uncovering the blowoff hole releasing boost until the other end catches up pushing the piston back over the blowoff hole.

Simple, now you owe me $10.

I don't know why you commie tutu-wearing garlic-eating pacifists even bother discussing your pathetic twin engine cars when obviously what you need is an engine for each wheel.

I've looked into it and figure I can fit 32 wheels on a regular sized car. 32 LT1s might be a tight fit though.

I suggested eight as a tasteful middle ground.

The outrage! I dont eat garlic, garlic is a living organism and only murderers eat living organisms.

If you ate a garlic today think of its children, who would feed and clove them?

Since it has been determined that Mercedes cheats more than Ferrari, they went all out to win the World Drifting Championship.
