Permitted fuels for Formula Junior
All Formula Junior competitors are reminded that the permitted fuels in Formula Junior races are clearly published in our FJHRA rules [ FJHRA Technical Regulation (6.7.17)].
For those who use Anglo-American fuel, the only permitted fuel that they retail is their excellent 100 RON leaded petrol. No additive may be added to that petrol. .Anglo-American 105 RON leaded fuel is not permitted
Higher octane levels permits higher compression ratios to be run without problems.
“If using unleaded petrol the maximum is 102RON/90MON
If using leaded petrol the maximum is 100RON/92MON ”
FIA App K, upon which this ruling is based, has just been republished as of 09.03.2011 , and the relevant extract is repeated here;
3.6 Fuel and oxidant
3.6.2 Except for what concerns non-homologated cars referred to under 3.6.3, fuel for non-homologated Cars must comply with current Appendix J Article 275.16.
3.6.6 Compounds, which are added to petrol to replace lead, may be added if freely available from commercial retailers. The addition of these compounds must not raise the octane value of the fuel beyond the limit of 90 MON nor of 102 RON.”
From Appendix J Article 275.16;
ARTICLE 16: FUEL 16.1 Fuel
The fuel must be commercial petrol which is available from service stations and must contain no additive other than that of a lubricant on current sale. The fuel must have the following characteristics: – 102RON/90MON maximum; 95RON/85MON minimum for unleaded fuels and 100RON/92MON maximum; 97RON/86MON minimum for leaded fuels”.
The Scrutineers at UK Championship, FIA Lurani, and Goodwood races may carry out random tests during the year to ensure compliance.
Class Structure since 2012
Following a meeting with FIA HMSC Chairman, John Hughes, the FIA expressed a wish to preserve the original 1000cc engines that prevailed in Formula Junior, and to support the moves by FJHRA to encourage front engined cars, Lotus 18s and Cooper T 52s in particular, to retain their original spec motors. As an aside, this will of course put less pressure on the original Renault and Citroen/ERSA gearboxes.
Accordingly, from 1st January 2011, in the “Millers Oils” FJHRA/HSCC Formula Junior Championship, and from 1st January 2012 in the FIA Lurani Trophy, there are new classes B1, C1 and D1 in Formula Junior for 1000cc FJ cars which will be treated pari passu for all purposes with existing Classes, and the 1100cc Classes are renamed B2, C2 and D2.
At the same time, the disadvantage in points to which Class A and D cars were put, if there were less than 3 runners in a Class, is being removed, and in exchange, with effect from 1st January 2012 in both Championships, where there are less than 4 cars in any Class, the points will be reduced, if 3 qualify to start to 1st-8 pts, 2nd-6pts, and 3rd-4 pts, if 2 qualify to start to 1st-6pts and 2nd-4pts, and if just one starts, then 1st-4pts .
However, there will be two saving graces, firstly, no car in the Groups A, B1 and B2; C1 and C2; and D1 and D2, respectively will get less points than they would have received if these three Groups had, respectively, been notionally amalgamated, and secondly, no car will get less points than it would have received if the points had been awarded on the basis of overall race results [eg if a sole Class B1 car actually wins the race, it will still get 10 points not 4 !!]
Whilst it may sound mildly complicated, it is a fair balance to encourage all the Classes out, without letting a sole Class runner walk away with 10 points every race!! The detail is of course included in the respective FJHRA/HSCC UK and the FIA Lurani Championship regs for 2012.
