Difference between Ron Champion and Haynes
Hi,
I've signed up here because i'm interested in building a Locost to race in 750mc.
After a quick browse many people seem to think the the Haynes is the easier car to build as Escort doners are few and far between. However, the 750mc
say the car must be built to the spec in Ron Champions book.
What are the differences between the two?

Hi James
The ron champion book uses the escort parts which means that you use a solid live axle.
The haynes uses sierra parts. The sierra has IRS (independant rear suspension) using a differential and drive shafts.
That is the main differance between the two.
As long as its fast.... i don't care

The primary differences are the Haynes chassis is 2 inches wider, and it's designed with independent rear suspension (Sierra based) rather than
the Escort live axle of the Champion design.

Hi
The Ron book chassis is what was effectively a copy of the live axle westfield chassis then re hashed here and there to suit. This is the chassis and
design that has to be used to compete in the 750MC Locost championship.
The later Haynes book is just a later book that has been done to make use of the later sierra donor. There is no Championship directly for use off
this chassis and would be non competitive for racing. It's more of a road cruiser.
There is no shortage of Escort bits to enable the build of a Locost championship car. I have many many spares and there's at least one other
racer within 20 miles of yourself also with plenty off spares. If you need any info or look over one off the 750 Locosts i have two sat here in
Erdington and there's 1 more in Great barr and a further 1 Wolverhampton..
Just U2U or give me a call if interested.
Cheers Matt

Thanks for the reply's, I used to own a MK1 Escort so i'm pretty familiar with that side of thing. Just thought it would be easier the use
a full doner car rather than trawl ebay for bits. Never mind.
This is my first attempt at anything like this and I can't even weld yet, so there may well be more threads asking daft question.

Hi
The only escort donor parts required are an axle and the 1300 Gt engine. The front uprights are Cortina and for racing the gearbox of choice now is
also the Cortina not the weak Escort item.
Is it the locost championship you are looking at or the RGB or Kitcar formulas as there's a huge difference between the specs of cars / build
requirements.

Definately Locost, as mentioned i'm new to this and it's comforting to know they have a good following if/ when I get stuck.
The Grand Plan is an affordable way into motorsport and a project to sink my teeth in to and learn with along the way.

Hi
well the Locost formula is certainly the locost way into motor sport. And is also a place where people are encouraged to build as much as they can
learning along the way.There's a hell of a lot of drivers with a lot of knowledge about building the cars. There is a parts pool for the harder
to find bits and pieces such as uprights axles gearboxes etc as most drivers buy them as they see them to ensure future supplies are available to
continue the formula for many years to come.
The regulations are very tight to ensure that there's only really one spec and are being tightened even further over this winter to take care
off any so called grey areas present. All in all the closest racing in the Uk at as good as it gets value for money for circuit racing.
As i say there's myself who manufacturers / stocks any parts required and 3 drivers within very easy traveling distance if you want to have a
good butchers round the cars and get a feel for whats under the skin of them.
Cheers Matt

It's just not allowed by the regs - which specify the allowed suspension which is non-IRS live axle. The full and detailed regulations are
here:

The haynes roadster (as built in the book) is a much heavier, bigger car that would need a much more powerful engine or a serious diet to be
competitive in most motorsport series.
If I were thinking of doing it I'd definitely take up procomp's offer of advice even if I didn't end up buying a chassis from him.
