A5197 Nissan Bluebird Turbo, P910 https://historicdb.fia.com/car/nissa...bo-p-910-17704 Homologated on 1 February 1984 makes the car legal for the start of the season, but then look on page 22. The 2 door coupé that Goode raced, was only homologated, as a variation, on 1 July 1984 - at a time when the car had already raced in six rounds! Then on 1 July 1985 the intercooler was added. Was Goode racing the coupé version in the early races with an exception and there seems to have been some confusion as to weather intercoolers had to be homologated or not, just as long as the road car was fitted with said item. Mitsubishi seemed to be late on that matter as well. A5113 Mitsubishi Starion 2000 Turbo A183A https://historicdb.fia.com/car/mitsu...bo-a183a-19975 Jesper |

Since these pages about the group A era of various touring car races and series was started, the FIA has made historic homologation forms available. Here I have chosen what I find to be one of the more controversial cars of the British group A era; the Graham Goode Nissan Bluebird Turbo.
FIA A5197 – Nissan Bluebird Turbo, P910 https://historicdb.fia.com/car/nissa...bo-p-910-17704 Allowed from 1 January 1984, so alright it was homologated before the start of the season. But then go to pages 22 and 23, and it is revealed that the 2 door coupé version that Goode raced was only homologated from 1 July 1984. By then Goode had raced the Bluebird in the first six rounds of the BSCC. It takes to page 28 before the intercooler are mentioned – homologated by 1 July 1985! If I read this correct it would mean that it was only 1½ year into it's life that the Goode Bluebird should have been competitive in class B. What was going on? Jesper |

The two previous posts were supposed to be one, just to explain the overlap of content!

Manufacturers were asked simply "is the air from the turbo cooled between the turbo & the engine? Yes or No?" Both the Merkur and Metro turbo fed directly from the turbo to the engine, but this included a finned aluminium section of pipe, so Ford and British Leyland ticked 'yes' as their homologation engineers were aware of the benefits. Datsun were typically more honourable and decided not to play the game. Graham (along with a number of other people) was unaware of this, so ran the car with an intercooler, but one of the competitors in his class lodged a protest at the end of the season and subsequently lost his points and the championship class win. |

Thanks for the background info VIVA very interesting to learn a bit more about some of the technical aspects of my favourite period of the series.

Thank you VIVA GT, for the clarification on recognition of the use of intercoolers on turbo cars in Britain. I was quite sure that Volvo did their homework when homologating their evolution during 1983, but can't find the word intercooler anywhere in homologation form A5020, as the regular 240 Turbo road car didn't have an intercooler, as far as I know:

Thank you for clarifying the intercooler issue, VIVA GT. I've heard it before, and by 1984 there were surprisingly few group A turbo cars around. The Volvo 240 Turbo was one, and I was quite sure that Volvo did homologate an intercooler when they did their evo in 1983, but can't find the evidence. But since the 240 (FIA A5020) aren't relevant to this thread I will leave it to rest for now.
The newly established Australian arm of Mitsubishi Ralliart entered a Starion Turbo for the 1984 James Hardie 1000 at Bathurst. Perhaps optimisticly they build the car to the expected 1985 specifications, but the governing body CAMS followed the written FIA group A regulations. The team went to tremendously trouble rebuilding the car to 1983 spec, including deleting the intercooler, before being allowed to race on sunday. This is to the best of my memory of having re-read the '84 Bathurst bible recently. Jesper |

Hi Jesper. Homologation form you mention is https://historicdb.fia.com/sites/def...20_group_a.pdf did not find any evidence of intercooler as you say. Water injection was homologated through extension 09/01 ET valid from 1 Sept '83 together with a new turbo (water injection specific tank capacity 30 litres). What is puzzling is that several extensions have been canceled over the years. May be the intercooler was part of country specific market (like the 530 Bimmer, ius version)? Much later, some japanese homologations showed that the lesson was learned, the intercooler being water sprayed (page 8, extension02/01 WR) https://historicdb.fia.com/sites/def...52_group_a.pdf

Hello,
I have a question about Rob Hall active in the series in 1983-84. Is it the same Rob Hall from current historic races? That would make him 18-19 years old if he raced in BSCC in the 80s? |

Watching him (on TV) during the '23 Goodwood Festival, driving the BRM V16, I was asking myself the same question. I came to the conclusion, that yes, it could indeed be the very same person. If he is in his 60s, around 70, he would have been in his 20s in 1984.
