Hidden potential of -modern- historic racing cars

Well come and compete with me in the CTCRC because we do and yet I have just read the Historic calender in Motorsport and Top Hats and God knows what else is mentioned but us, oh no (just why is that?) and yet our championships are probably as honest if not more so than any of them and bloody good racing as well.

I would say we are now going to other hidden things which where actually not meant here . But the capacity of reving higher by using modern materials like steel rod, cranks cams, valves, modern oil made it all more expensive. And then with those made to measure cranks and rods, stroking is not far away actually.
But all those mods made classic racers more reliable alltogether, didnt it?

Now this could get interesting. I had many a conversation with our eligibility scrutineer (AHC Championship race series) and nothing was ever done. The organisers knew cheating was happening and did nothing, anti-tramp bars were a common 'cheat'.
As for big engines, I can say here and now that I would have been happy to have mine opened and inspected by anyone. However, I reckon there are one or two that wouldn't be too happy. What say you....?

Do you know that there are actually racecars which are so developed on Dunlop racings that they go slower when they use Avons..........The soft , bumpy Dunlop racings make an important part in the suspesion set up together with mega developed shockers and suspension geometrics

Hi Esper,

No argument there. My engine was capable of sustained 7500rpm running i.e. Spa six hours, no problem. Do or die, I'd use 8000rpm. But I know my engine wasn't stroked or over-bored, it was just a well built engine using the best bits available built by the best, the Welch's.
I know that there were/are oversize engines out there.

Are you talking about ZZ's? If so, yes, I'd agree. I could shred a ZZ in a ten lap ten race in the dry, Jeremy or Bruce would take about 6 laps.... That's one of the reasons we stuck to Dunlops; as well as the Dunlop being a period tyre and looking right.

As has often been said,the Histos should become mandatory for "our" racing ,they suit the types of suspension better.

No not ZZ cars, German car with real shockabsorbers not those hydraulic twin piston pumps we use..................

Dont forget that antitramp/raidious arms were used in period Slippy

but it was not in the documents

You sure Esper,I can check with Bill Price,he was in charge of all Homologation at the works

I can only rely on scrutineers..............who tell you whats not and whats "FIA" so everybody thinks its leafsprings and Panhard rod.
(There we go on Healeys again which is such a flat beaten track! lets talk about the cars nobody seems to know which are or can be very fast, lets talk Bizzarinis and Iso Rivoltas, Corvettes , and??????????????)

I'm pretty sure. Tramp bars were definitely a no-no for Healey's if running under FIA.

Avon ZZ tyres...

thats my game as well, but Slippy lets get to the lesser known cars which were fast and nobody complained (they didn't know and so they are (or where)) afraid to try to put some opposition. you know the British build cars are all to well known (one of the prolems to be anflophyle)

Its just about something people are used to but don't offend me into judging which tyre is the best ................................but years of development into cars with dunlops Rs okay you might be right!!!!!!
So in one thing if it was only up to dunlop Rs no problems left!!!!! but don't tempt me!!

GT40's (most of these are as bent as a nine dollar note, in my opinion), Corvettes, Porsche 911s, indecently fast MGBs, the odd 'lightweight' E-Type, Bizzarini's etc etc etc etc.

The real fire eh? My problem is that I've been away from the historic scene for a little while, who's cheating these days, besides chemists, allegedly.

Slippy its not about bending the rules or cheating and not even today its about how to use the rules to win ( to win what? the worldchampionship of your village?, theres no money involved anyway!) so its about cars which where there and are still there to be used to win the championship effectivly....

Sorry, getting carried away there!

[johnny yuma]

Lets look at it through that old motoring journalists cliche that as far as the racing of cars which were built to carry a number plate go,people want to see their car beat their neighbour's--within reason.Widening the wheels yes,flaring the guards and chopping things out of the way no.Different carburettors yes,EFI no.Original drivetrain yes.Stroked crank,custom gear ratios no.Slavishly keeping 4.5 inch rims and period looking tyres seems overly purist [not that theres anything wrong with that]

The point is that hotting up old cars does not stop at some point in history.
Let it evolve within understood guidelines,and as esper says there is no prizemoney so keep a sense of humour about "cheating" ,and peer pressure will isolate the true crazy cheat.

It does according to FIA Appendix K regs.
