• your name and the county (or country if not the UK) where you live
   
• brief details and a picture of your vehicle
   
• your Race Readiness Rating (see below)
   
• whether your car can do 100mph (see bottom of page)

Simple as that, no fee, just register your interest in what we're trying to do and add your support to our crusade!

(It's not actually that important if your car will actually do 100mph or not, the main thing it to unite enthusiasts for a 1-litre racing revival)
 

Our unique 'Race Readiness Rating (RRR) has been developed to help us establish the likelihood of obtaining our goal of producing a grid of cars.

Please let us know what category you fit into:

1 - I want to be a member but I wouldn't really consider competing
2 - I'd consider racing and I'm looking for a car, or I own a car which needs work/modification to make it race-worthy or eligible.
3 - I definitely want to race and I'm building a car either for this series and/or to race elsewhere, budget permitting
4 - I own a car which could be raced straight away but I have no experience or licence, but I want to race
5 - car as in category 5, but I also have a race licence, possibly experience etc - i.e. fully 'race-ready

A bit of (imprecise) science for your interest and amusement

Just out of interest and as a rule of thumb, for the typical 1960s/70s small saloon car of let's say, average Cd of 0.40, frontal area of 18 sq ft, 850kg rolling weight, to achieve 100mph your target bhp need 'only' be around 60-65 bhp.  How you get there, and how long it would take you, is of course a different matter and the weight of your car will have much more bearing on its acceleration than on its top speed.

Of course as speeds rise then the power required to obtain those speeds rises very dramatically.  This is because the power required to overcome drag rises to the cube (power three) of speed i.e. for twice the speed you need 2 to the power 3 = 8 times the power.  So for a car that will do 100mph on 60 bhp, 480bhp would be needed for 200 mph!  This is why even powerful or lightweight cars run out of puff and also why acceleration takes a lot longer at higher speeds than lower speeds - power is being soaked up massively to overcome aero drag rather than weight.

Most people don't appreciate that, apart from mechanical friction in bearings and tyres,  the weight of a vehicle has very little bearing on its theoretical top speed.  As speeds increase, top speed is governed pretty much just by aerodynamic drag and bhp, so Cd, frontal area and horse power are the main determinants, although weight and tyre inflation do of course determine rolling resistance.

As 60s/70s sports cars are generally smaller in frontal area (although not necessarily possessed of a better Cd) than saloons, the bhp required for the magic ton is correspondingly smaller.  e.g. for a Davrian plus driver weighing 600kg, 14 sq ft frontal area and same Cd of 0.40, 100 mph should be obtainable from only around 50 bhp (i.e. a standard Imp Sport engine).  And 200mph should be obtainable from 400bhp.......

These figures were kind of arrived at from playing around with this page from Bowling and Grippo in the USA
