Also, please be aware that cardboard is not considered a suitable material for the radiator/s

Back to radiators, I have just spoken to a gent to worked for Ralph Broad in the injected GT, early RS1600 days. He reckons that radiators were most likely carried over from Gp5 cars, and be copper rather than aluminium. It doesn't mean that another team weren't using alloy, of course, and big question which will probably remain unanswered is when first adopted?
I asked said gent about period pics of suspension etc. 'Never thought about it'.... If only! |

Welcome Anglebox!
Interesting and I suppose logical account of why BDA and BDG were named as such. I always thought that the BDA was always a smaller capacity engine than the BDG in any case. I thought BDG's were always 2-litres and BDA's no more than 1600cc? |

I thought that in GP 2 format the RS1600 was a 1999cc BDA

(However, I have also heard the BDA referred to as the Belt Drive A seies!) This is certainly how it worked on the 2 litre turbo engined used in the Sierra and Escort Cosworth models, the YB series bagan with the YBB used in the first two-wheel drive cars (YBA was the prototype), then YBC was the Group A version of this, and so on... |

BDA= Belt Drive A series
The last letter was then used by Cosworth to denote different bore & stroke dimensions. That doesn't mean there weren't other capacity versions of BDA produced by alternative engine people and still called BDA..... BDG= Belt Drive 1989cc version of BDA. (Originally iron block) BDH= Belt Drive 1298cc version of BDA BDR= Belt Drive 1699cc version of BDA etc etc. Gear driven engines were 1.6 FVA and 2.0 FVC. |

No. Proper Cossy BDG was 1975 cc.
Also, there is no such thing as a carburetted BDG! All authentic BDGs have Lucas mechanical injection. There are, though, plenty of carburetted 1998cc BDAs. FVC was 1790 cc, although a number of contemporary builders such as Alan Smith and Geoff Richardson did IIRC offer long-stroke versions of 1930cc and 1970cc and the like.

I wish I had a few genuine original Cosworth FV/BD series engines tucked away in my store cupboard now....

I thought the 'A' stood for Anglia as the Cosworth line of engines all began with the 997cc Anglia unit and it's derivaties.
MAE - Modified Anglia Engine SCA - Single Cam Anglia BDA - Belt Drive Anglia FVA - Four Valve Anglia Similarly the DFV stood for Double Four Valve being based on two FVA engines in V formation. Though I could be wrong. |

I think that what we're all proving here is that there's a lot of folklore connected to these Cosworth engine descriptions...

Until recently I owned AMR XOO 347F. In 1971/2 it was used as the test mule in UK club meetings for the BDA alloy block in Shell colours run by Don Moore Racing and driver by Gillan Fortesqueu Thomas at 2060cc. The car was bought in 73/4 by Alec Poole and Derek Mcmahon with an 1800 injected BDA. Thereafter BD(A)s were nearly 2ltrs in capacity. In historic racing today there are other thiings that determine if an engine is BDA, BDG, BDX etc such as valve size, manifold studs, spark plug size/type etc. Legend is that Cosworth did not aprove of the alloy block, Ford insisted on it after Brian Hart made it work. |

Original BDX was an iron-blocked Swindon-built big valve BDA of 1993cc. Did it use 10mm plugs like an FV-series engine to allow for the big valves?

Cosworth engine series names
OK, just in case anyone other than me reads old threads .....
SC stood for Single Cam .... hence SCA (single cam model A) FV stood for Four Valve hence FVA (four valve model A) FVC (four valve model C) .... FVB never made it out of captivity DFV stood for Double Four Valve BDA was Belt Driven Model A BDG was therefore the 7th BD model in the series BDJ the 10th to see the light of day ..... hey, I was there at the time!! |

I think the 'A' in FVA and BDA stands for Anglia as all derived from the Ford Anglia and the Cosworth MAE engine was 'Modified Anglia Engine'.

If you talked about an "A " series engine it was a BL small capacity like A 30/40 etc . So from a long time ago I have believed that the BDA was Belt Driven Anglia series |

The 105E 998 c.c. engine was only a three bearing crank: and side-by-side induction-exhaust. Whereas as the Cortina was five mains. And the FVA was based on the new crossflow engine, from the Cortina. I seem to recall, Duckworth managed (Thanks to his development contract with Ford) to get his hands on an early version of the Crossflow Kent engine, as this released in general usage in 1967, however the first FVAs were released in 1966. The development contract with FoMoCo was in two separate parts: firstly for the FII engine (Which was designated "FVA") and later simultaneously the FI DFV. The DFV of course, being effectively two FVAs laid over, side-by-side in order to create the desired "V" block format. It was then common for Ford to release a few prototype engines for analysis and development, (prior to general release in facelifted and new vehicles), alongside their own internal development, then mainly at the Dunton facility, in Essex. I was working for Ford Europe at this time, 1966 to 1967. Also worth recalling, Terry Drury of Supervan fame was also then a development engineer at Dunton, mainly working on dyno tests and cylinder head design: which was bloody handy for Terry, as he used to get through his work work ASAP and then use the dyno time for developing his own race cars! The original crossflow iterations (Both 1,300 c.c. and 1,600 c.c.) suffered serious pre-ignition and spot overheating problems until the flame path progression was sorted. It was also very sensitive to ignition timing and plug heat range: easily burning out pistons. Terry's able dyno assistant, Alan Cornish, later work together at European HQ at Warley, Essex. |
