I watched this the other day, I remember watching it when it was first shown. I thought it was all a bit amateurish at the time....

Do you think? I really like it. Imagine that level of access for a TV documentary these days.
Amarteurish TV work, or engine work? it was the 80's I suppose :laugh:

Great, I watched both parts. It's amazing to see how fundimental it all was and engine management mistakes being made that todays amateurs wouldn't make. It all seemed much more entertaining though compared with today's stuff.

as an electronics guy it was that that I found amateurish, but then if I had a camera guy following me around all day trying to make a story I'm sure he'd catch me making stupid mistakes too :D

I can't believe that Cosworth ever imagined that they'd use old BD engines in the F1 program, my guess is they just wanted to blow a few up to get an idea what was needed.

Did ford not go on to use that engine in the rs200 1.8 bdt-e ?

good point, similar era too. They made a lot less power than the 1500cc F1 engines though.

To s certain extent, I suppose they had to.... In between stages the rally cars are road cars, drivability and reliablity are higher up the list than with f1.

Don't forget, the old BMW 2002 4 cyl was used to help nelson piquet win the world championship.....

great find, enjoyed that, funny when i look at the turbos they look so basic, really makes you wonder what they could do today if allowed, now that would be exciting :D

Did anyone see the Renault v6 engine with the throttle on the wrong side of the turbo? Bolted on where the airfilter goes. Surely when the throttles shut the turbo stalls?

Thats how they ran, with a similar system on the group B cars (DPV). Its job was to improve throttle response.

Quite the opposite, the compressor is in vacuum so it has little work to do.

Funny you say that I was reading a few threads a while ago about that. they had one before the turbo and before the throttle body. it created a vauum which help keep the turbo spinning off boost.
