new haynes chassis
hi,
sounds a bit of a stupid question but im curious... is the new haynes chassis meant to be any better than the old ron one? what are the main
improvements if any i.e. is it stronger etc? also are any companys going to be building ready made ones/offering parts/kits for the build as soon as
the book is out or will it be a good while before this happens?
thanks in advance
mark

alright mate the new kit is sierra based therefore any kits that are already available by all the other manafacturers will be almost identical to the
new haynes 7
and there wont be anything available that you cant get already
if you built all the cars to a rolling chassis they would all look almost identical apart from bits here and there
its only the body and finishing touches wheels etc that make one car look better than the other etc
and improvements to measurements etc

do you think that each make is totally different build wise than the other?
each kit is about the same to build MNR is suposed to be real good finish not that theres anything wrong with the others
they all bolt together in nearly 100% the same way
some are old escort cortina based new ones are IRS sierra
if you took 2 different cars apart you could basicallyt bolt 95% of one car back onto the other if you get what I mean
Also the new haynes car doesnt half look very MK INDY perhaps with a few added bits
AFAIK the locost difference was its sides were 1" shorter

the new haynes roadster is a design by Martin Keenan at MK engineering, the chassis designs remain his intellectual property and as such, only him or
authorised agents will build cars to that *exact* design. People will undoubtedly be making things to fit the chassis' though, ie wishbones, but
again probably not to the precise book specifications. This is my understanding from recent posts by chris gibbs, the author.
And to answer you more precisely, i believe the new and 'old' chassis' (remember, this new book and chassis is nothing to do with
Ron Champion at all) will not be particularily similar. I would expect both improvement and refinement.

just read the ppc article on it and they claim the new one is near on twice as stiff! i have my book on order and where i would be happy to learn
along the way in building a car creating the chassis + wishbones themselves i would like to leave to professionals

Believe one difference is that the "New" car is 2" wider than the old "Book" car. According to PPC it handles very well,
but then so do most/all of the old style ones, mine at least handles better than I can drive.  Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

New Haynes Book
Just to clarify the situation – the new car, the Haynes Roadster, has been designed by the author of the new book, Chris Gibbs, with invaluable input
from Martin Keenan at MK, who built the prototype car.
MK Engineering are able to supply everything needed to build a Haynes Roadster.
The chassis is indeed an improvement over the design appearing in the previous book, and the finished car raises the game significantly, as I think
everyone would expect.
Totalkitcar have a feature, including a road test on the car as their lead feature in the latest issue.
But... the proof is in the pudding. The new book will be in the shops on Friday (2nd March), so go buy a copy and build a car!
Happy motoring.

Well i am thats for sure. OK might be slightly adjusted but surely that was and is still the idea? Locost, Fun and you build it!
What is the point in buying a book to build a car to then go and buy all the bits necessary from someone else!
Ron didnt do it that way that is why the book was so succcessful!
The new chassis may well be better, stronger etc but is that really the idea of the car???

You don't have to buy all the bits from someone else, and detailed specs and dimensions are provided for all components, that's why the
book is called "Build Your Own...", but those who don't feel they want to do everything themselves will be able to buy parts, as per
the Locost.
Good luck with the build.

Is it just for an IRS, or does it cover live axles? Only got the Sierra wagon and Cossies down this way.
Should be able to adapt it to for other IRS donors - Impreza WRXs are ten-a-penny here, as are EVOs and rwd Nissans (200SX/Sylvia).
Hmmm - I see a Mitsi beast - EVO rear, L300 front uprights and rack, Starion/L200/L300 box, 200bhp FTO V6

Book covers IRS only, with Sierra as main donor.
Mitsi beast sounds interesting!

The totalkitcar guy was here the other day, think he's going to do a feature on us or diesel tuning or something, and dropped off the issue with
the New Book review.
Having a quick look it doesn't go into that much technical detail.. says the new car is IRS all round and uses a fabricated steel upright at the
rear. Says the book has lots of new CAD drawings and things too. I'll be getting a copy when it's out, to go on the shelf with my grubby
old one.

If the chassis was heavily influenced by MK I assume this may actually be an "improved" MK Indy chassis (the current official Indy chassis
is meant to have some geometry flaws?)?

Guess what? New book arrived from Amazon today. Chassis is 2" wider, tube layout pretty much identical except behind the rear bulkhead to mount
the diff. Tons more construction detail including a pedal box and detailed engine mounts, lots of info and detail for building jigs for wishbones etc.
Lots of other nice details, even an origami seat! The drawings all look good and there is even a section in the back with tube by tube drawings like
the McSorely set.
I am looking forward to a good read tonight!

Before I start building my hybrid of a +4 / 442 derivative (wider longer etc) with cymtriks stiffener suggestions.
Is this new chassis going to be any stiffer, and will it be able to take an engine from an Escort Cosworth bearing in mind the size of the lump width
wise with Turbo and pipes fitted.
At present standard boost with a T5 box, later hoping to take the lump to near around 380 BHP. With a Torque biasing diff.

a hybrid +4 chassis would be quite wide would it not? is the chassis not already +2 over the old one?

Being 6 ft 4 ins tall and built on the large side it needs to be a bit wider to accomadate what is commonly known as a case of "lard
arse".
Plus the lump going in is near 30 odd inches wide overall (came out of a escort cossie).
So now you see my slight problem and in doing a Hybrid such as I am doing in some scrap 1x1 wood battens. It needs to be so.
