Looking good!
Hey Everyone,
it's starting to look good! I think I'll stick with this design! Just need to start detailing it.
Will start working on a nice website for it soon since I am starting to bloat this thread with pictures:-)
Tell me what you think so far?

So it has a roof again...
I think it lloks pretty good, but I'd either lower the roof or make the wasteline higher. Just an idea...

I am thinking about raising the back a bit. The actual top I am not going to finish until I have a good idea how the size in real life is. The roof
may be higher then needed but it might also be that the roof is to low.
Not sure what the best way will be to test it. I am thinking about building part of the car from wood 1:1 scale to find out. They had a sale on wood
the other day at Gamma so it should be cheap enough to do. Then I can deside if it is to high or to low. Also the wood frame I could complete the body
work on and use it as a counter mold.
But dunne know yet, seems like an awfull lot of extra work....

Okay now we are getting somewhere for real. Got the doors in (still need windows) and the frame is somewhat further developed now. Still need to fix
some things at the engine compartment but other then that I think this is pretty much finished.

Looks good, but you might find it easier to get in the car with different doors. When you use doors like the 787B or Ultima they'll be less in the
way. These sort of cars aren't easy to get in and out anyway, so you might want to get the best result on that topic.

Hey Bert,
I'm not to afraid of the doors. The way I designed them to open means there are totally clear of the opening.
I haven't completely figured out how to make them stay up, probably some gas struts or something.

On hold but not indefinately
Hey Guys,
Just a small update here, I had some very expensive repairs on the Delorean the past few months and things have changed.
I have desided to not take changes and I am going to go for a normal locost following the book and build it bit by bit as I have money and time
available.
After that I may still get back to this project because this is really what I want to do but right now it would be irresponsible.
Anyways, with luck I should start working on a locost sometime during this summer. I probably will even go rotary:-)

Bas, sorry to hear the mid-engined project is on hold, but also glad you are still building something....and that the middy is still there in the
background.
When I started mine I always wanted to build a "supercar"...kind of Ultima beater (and still do to be honest), but things like doors,
windscreens, ventilation etc. always surfaced to slow me down.
Then, after building my buggy I found the Locost movement. The search was then on for suitable donors.....after what seemed like ages searching in
vain (probably a month or so to be honest) I though why not do a similar budget style approach, but with a middy....
I could lose the doors, the screen and so on and have a "simple" build. The rest is history as they say...
Anyway, good luck...at least you'll be building something.

Hey Alan,
The difference is, you already build a number of things:-) I'll certainly go back to the midengined concept eventually, I just first want to
build something where most of the questions are answered, following the book wherever I can, only deviating there where needed because I want to go
single donor and have a different engine choice.
If I do that successfully, then I am ready to design something myself

Well Bas, even if you want to go Locost first, which I believe is a good idea for a first time builder (like you, or me ) anyway, you still could
go mid-engined .
To most imoprtant thing to get a powerfull, sporty and entertaining car would be power to weight ratio. So the car must be kept lightweight. No roof,
nor doors would make the build not only simpler, but also cheaper. And a lot is possible on the Seven-like chassis, looking at the caterham 21 (which
of course is not a Locost at all) If you design the car to have the cockpit further up front you can put that rotary engine (remember: it is VERY
compact) behind you, a bit in the style of the old Auto Unions...
My project hasn't even started, yet got cancelled again... After finding the Belgian MOT doesn't agree with 225/50/15 tires on my 1982
RX7, nor with the lowered suspension (still driveable, don't hit the streets or anything), I cannot see how the are going to allow a self build
car.
It is possible, but right now, finding out the laws in Belgium, and how to make the best of them, is priority. If I can find a legal way to build and
register a self-build Locost, I will go ahead. Otherway, I might just aswell move, I hate this over-regulated country! Need any train drivers in the
UK? ![](/images//smilies/bigsmile.gif)

Hey Bart,
Nah I'll go standard RWD first. Experience is what I need now:-)
I hope the APK and RDW laws in Holland stay the way they are for now. If I take to long building this car I may also run into the same problems as the
European Union seems to be keen on making selfbuild cars an impossibility.

I have done a finite element analysis of several car chassis and I would suggest the following for your mid engined design.
The engine bay will need some diagonal braces. Take a look at tube R on the lowcost plans or at the Y brace on the Lotus 23 chassis for ideas. Two
diagonals, one on each side of the engine bay are much better than one.
Don't use that bent tube on the outside of the chassis running from the passenger region to the engine bay. The bend is a bad idea as far as
chassis stiffness is concerned.
The tunnel down the centre of the chassis probably does not contribute much. The lowcost chassis is certainly better if the tunnel tubes are replaced
with a simple sheet steel welded tunnel with minimal internal bracing.
You may be better off, weight for weight, with a ladder frame. The massive superiority assumed for spaceframes is just hype. Most spaceframes are
actually less stiff than a well designed ladder frame due to inadequate triangulation. With additional triangulation and some minor redesign it is
possible to double the stiffness of the lowcost book chassis, reduce the number of tubes and reduce weight aswell.
I have written my analysis results, which cover several types of chassis, into a Word document which I could e-mail to you if you want.
Good luck with building your car.

I would be intrested in some chassis anylises, for future projects.
I'm planning a locost type car for the (rather) near future, to practice skills, but would like to build a more serious car after that, so any
ideas are welcome (mid engined car, rotary powered, ...)

yeah I would like that analysis aswell, the MR project has been postponed for awhile but it always helps getting info
Send me a private message ok?

Introduction
Hi there , my name is Paul.
I intend to daydream about building a small midengined car(thou i think it would be imposible to get it registred in germany) ((
but ...............one never knows ;o))
hope to learn a good deal from you ...

Well, it'd be easier in Germany then in Belgium! It is possible to register selfbuild or seriously altered cars in Germany.
But to find out the exact regulations you should contact the TUV.
Overhere rules are easy: nothing is allowed So to get a kit-car or selfbuild car registered I'd have to get it through SVA or TUV and then
import it to Belgium!

Hi Alan ,
thats the place I came here from..... :o))
realy great stuff.
My intetion would be to go very much smaller,something like honda S800 or Suzuki Cappuccino (just midengined)or a smart roadster.
my opinion is that you dont need a lot of horsepower to have fun.
but it seems hard to find a suitible donor.
I thought of using a bike engine,but how to make it reverese?
and after all it should not cost a lot because it ´s all never going to see a road(legaly at last).
any thoughts welcome.... ;o))

Paul,
As the owner of 7 different S600's and S800's over the years (not all of them complete and running I admit) I agree completely that you
don't need a lot of power to have fun. A reasonable power-to-weight ratio and a well tuned chassis will be much more fun than an unmanageable
monster with a huge engine.
I'm intending to start construction on my mid-engined car in the next month or so and will probably use a current model Corolla engine (1.8l
1ZZ-FE) because local registration laws mean I must comply with the same emissions laws as new production cars
If I wasn't constrained by those rules I would look very seriously at the 1.3l Suzuki motors (G13B I think) which are light and quite powerful.
A motorcycle engine would be nice but, as you say, transmission issues complicate it a lot. When BMW made a bike engined show car (the Just 4/2 - see
link) they connected the K100 motor to a conventional transverse FWD gearbox. That trick
would be a lot harder with most other bike motors unfortunately.
Good luck with your project.

Just check some of the bike powered kit cars around these days. No problem at all to get a reverse! You keep using the bike gearbox for the forward
gears (you even get sequential shift with them!) and a reverse gearbox extra. That really isn't an issue to worry about. Different models are
available, so you'll just have to find the one that suits your concept/budget best.
