FIA Homologation, proof for twin carbs and electronic ignition

(1/3) > >>

Jasonkennedy:
Hi, I'm refreshing my race Beta to go 'Youngtimer' racing in Europe (mainly on the Nurburgring) I am hoping to do this without a technical item known as HTP papers (Historical Technical Papers). If it turns out I do need HTP papers then if I am to use twin carburettors or electronic ignition I will need to show evidence that it was used in period in an International event. I have found mention of both items in Brian Long's book 'Lancia Sporting Coupes' (P172), and also of twin carburettors in his Beta book. I have also found several pictures of the works cars with twin carbs on the RAC and Monte Carlo rallies.

However the FIA give a priority order for evidence from strongest to weakest. The strongest would be evidence from the manufacturer in period, produced in manufacturers documentation or period magazine articles. The next strongest is from recognised experts who inspected the car. Of the least value, but which consideration will be given is books and magazine articles written out of period by reputable authors. Recent letters from
people, manufacturers of the period may also be considered.

Does anyone have any of this proof or any leads on where I can get it?

Hi Jason

Interesting subject and there is not a lot of info around. The main reason was that the Stratos was homologated for rallying at the same time as the Beta Coupe, the Beta was very much the poor relation and from what I have read only ran for approx 1 year (maybe 2?) in Intl events as part of the factory team.

I have a copy (maybe not complete) of the homologation papers if that helps, but depending on how strict they are, it will be a difficult one to replicate. The reason being that the G4 car ran a special Abarth 16V head as well as the twin IDF carbs, with the engine inclined even further than normal. The G3 car, I am unsure of as the G4 and G3 descriptions in everything I have read get merged, so suspect the G3 had only a single carb as per production. No idea if the car went circuit racing Internationally, just the records of the rally versions appear online/in print.

Peter, thanks for the offer of the papers, I only managed to get an incomplete set from Lancia forums etc so I bought a complete set from the MSA. From my experience of FIA cars I've had and speaking to an MSA register, it is not necessary to completely replicate the specification that was used in period. It is possible to start with what was homologated as the standard car and then use just the modifications made in period that you want to use. As you say getting an 1800 cc engine with the Abarth twin cam head would be near impossible. FIA rules are a little clearer for pre 1965 cars as so many are raced, but for later periods such as that for the Beta it is difficult to find information or advice on what you can and can't do.

The Youngtimer Trophy organisation's rules as confirmed by themselves by e-mail should allow me to race with them as long as I have the Homologation papers and a vehicle registration document and the car conforms to these and is modified in accordance with the Appendix J of the period. I'm going to their test day in March so I'll see what they say then! Their only concern was that my roll cage did not have a certificate so I'm just finishing fitting an FIA homologated Sparco cage.
Cheers, Jason

Hi JK,
I think idf would have been unlikely as they sit inline with
the body, more likely dcnf which sit across the car.

I would speak with Guisepoe  Volta,
he runs the historic Lancias and would
probably know what was used
back in the day.

He is on fb

Hi Geoff

I believe this is a photo of the G4 engine.

I thought I had read that they were IDF, but happy to stand corrected.
