3 seater car?
I am soon coming to the end of my build and I have already started designing my next car!
What I would like to ask is will an R1 engine be capable of pulling a car with 3 people?
The idea is that I have a central seat as I like the single seater designs.
I like the idea of a bec .
I am not planning on thrashing it with 3 people, but at the same time, I do not want to ruin a good engine by overloading it. I am just at the idea
stage.
Any advice?

The obvious choice (to me anyway) would be the Aeon GT3. It can easily take a whole range of bike & car engines and handles like a dream.

I have looked at their website under 'engines'.
They don't mention bike engines, they refer to ford zetechs

having been two up in 3 bec's the drivers tell me they are a lot quicker with just the driver so there is definately a performance degradation
due to the extra weight of passengers - if the car weighs 450kgs and the three passengers weigh 240kg's in total (approx 80kg/12stone each)
you're adding quite a bit of weight and killing the power to weight, especially when bike engines rely on revs for the power and have little
torque.
imho..

If you can get the finished vehicle weight around 400kgs, I don't see any reason for not using a bike engine. Should still give frightening
performance.........

I admit that the Aeon isn't as lightweight as some bec's but then it has a lot more in terms of comfort. I estimate that you are looking
at around 550kg with a bike engine installed.

If you're designing and building the next one as you did this one, then just design it with space for 2 engines - problem solved

Someone I know has already done it

I am thinking of a bare bones chassis along the lines of the atom, but with 3 seats. Most of the time it will just be me driving, so hence the central
driving position.
One of my concerns is the clutch handling extra weight.

A 400kg 3-seater?! I agree with the earlier comments, weight is very much the enemy of bike engines and a 3-seater will just kill the advantage of
using one. McLaren's F1 street car is a 3-seater... with a V12 to propel it.
