Locost GT40
So here goes-I'll come out of the shadows! After building two locosts, I've built up the kit, the network and hopefully the skills, I feel
it's time to move on- but to what? BEC? Mid engine?
But after Practical Performance Car's article on Graham Turners GT40, this must be the way to go, but I just can't bring myself to buy a
chassis....that's the fun bit!!
So, how to overcome the first problem- chassis plans. As any internet search has been unfruitful, and I possess virtually no computer skills, do I pay
a chassis designer? If so, who? Any suggestions? Do I wait for an abanboned project? Or do I just pay up and shut up?!
Anyone like minded? What do you think?

Hi Drew,
GT 40... mmmmmmmm probably THE most beautyfull car ever made!
I'm certainly no expert but if you have made two locost's you surely must have confidence enough to build a midengine chassis.
The thing that would worry me the most would be the bodywork/glasswork/doors etc...and not the frame...assuming you're not gonna use a 800bhp
monster in the back.
There sure must be some websites with pictures of the GT 40's frame (locost style that is)
If you have some pictures and a few dimensions you could be on your way.

Just found this on e-bay while browsing, might be interested in it. May need a little work, but a good base for a shell.

i'd scratch build it. start by tacking together an untriangulated frame to hang things on, then cut and weld it until it looks right, then add
some triangulation til its is strong. then start again and make a perfect version. Doing it this way would allow a lot of experimenting and testing,
and wouldnt even waste too much metal.
my next project is a gt38 (like a gt40 but only 38 inches tall, rather than 40!)

I think the best compromise is to buy just the shell from some place, then make your own chassis to suit. Doing the composite yourself will be
educational, but take years. Doing doors sucks dead donkey dick... Seriously, doors take an enormous amount of time, and even then they
won't work right half the time. Do yourself a favor and just buy the shell.

How fast are you planning to go in this car? I understand that the original 40's were notorious for generating lift at high speed (not good).
The modern GT does not have this problem. The development team farted around with the front design to eliminate lift.
Personally, I think the GT40 is a good looking car, but it is a bit too often replicated. Now, a Miura, that is something else:beauty, class, rarity,
and sex

Cita & KB58 - I agree with you guys, the only bit I wouldn't consider doing is the glasswork - bad experience with a poorly made Kayak!
Mangogrooveworkshop - the lmp and 'Ultima looking' car are really cool, but I've been bitten by the classic lines of the GT40 and I
can't be distracted from that - that's the only way for me. Although I'd show my appreciation to the auto designer of those cars if
he felt like getting involved - regardless of which side of Hadrian's wall he came! Many thanks for the era pics.
AndyLancaster3000 - great find on ebay, certainly worth considering. Let me know if you find anything else!
JoelP - GT38 sounds interesting - any pics or anything else you can share would be greatly appreciated.
Could ANYONE recommend a space frame chassis that could be modified for the GT40?
Greatly encouraged by all your responses - keep up the good work. DrewB.

I have been involved in the building of 2 GTD40s and complete rebuild of a third.I have also worked on several others.The chassis on these cars are
very overengineered,heavy and complicated!If you could find a chassis from one of those horrible Lamborghini kits that were popular in the 80s you
would have a good starting point.Most of these are very similar,I think the wheel base is the same.They also use the same suspension setup i.e.Mk 2
Granada front uprights and brakes.At the rear are fabricated steel uprights, again very heavy! Also at the rear are long trailing arms and again
Granada brakes are used.I do know someone who can supply aluminium rear uprights. I think you would have to add some outriggers to the side of one of
these chassis as the GT40 uses saddle type fuel tanks.Gearboxes are usually Renault units, the 21 turbo being favourite(better ratios)though I have
driven one that had an Audi 6 speed which I believe came from one of the large turbo diesels.If you have any more questions send me a U2U Glan

If you want a chassis designer to work with try darren@gtstuning.co.uk
I've done a bit of design work in the past, and wouldn't mind a new project.........
Kind regards,
Darren

Just read in the paper today that the "father" of the new Ford has been "retired"; he got to watch car #8 being built, and
then got to take it home for a leaving present! he is building a garage for it where he will also have things such as magazine covers and blue prints
displayed.
He is only 54, and says that he will be joining Carroll Shelby for "special projects"; it will be interesting to see what the pair of them
will cook up.
Cheers

Update: In the past week, and probably this weekend, I hope to find pics, links & specs to assist the chassis designer. So . . . which are
considered to be the better names out there in the GT40 world? (It should be noted that this will be a new design, but it does no harm to check others
out).
Principles: I intend to work within the same ones that worked so well for Ron Champion - build the best you can with a keen eye on costs (best price)
- no point having the best GT40, but it never seeing the road! It must also be progressive - I don't like things hanging on, as far as
financially possible. My aim is to bring the GT40 into the hands of the normal working man, ie. me, and help others to do the same. I hope the team
below are going to help me do this:
senior GT40 builder, sheet metal worker, Fabricator (www.arrowengineering.co.uk), coded welder, designer, development engineer, designer/supplier, and
me (www.vaspracing.pwp.blueyonder.co.uk).
Not all of the above know about the team - it'll be a nice surprise - may be subject to change, so no names! However, if you feel you can bring
something to the table, pull up a chair. Many thanks. DrewB.

Just seen this thread, brilliant! I would love to build a GT40 replica but cost would also be the main issue for me. Please keep us informed.

try looking at ultimav12.ca and the seven.info site/files section/kitcaranalysis.doc(version2)
The first site shows how an Ultima chassis was uprated. The chassis stiffness is quoted at each change to the chassis so that the effect of each
change can be seen. The kitcaranalysis.doc is written by me and shows the results of my analysis of the Locost and some general information on chassis
stiffness. I do structural analysis using finite element analysis for a living at RR btw.
If you post your ideas on this forum I'm sure you'll get some friendly advice.

Cita , thanks for the u2u and yes I do intent to keep this forum up to date, with regard to the "team" however ... does the sound like a
but?? well it shouldn't because enthusiasm and willingness goes a long way in my book ( ten pressed men and all that) we will gladly find some
thing for you to contribute, Thanks again. Drew
