1991 Ford Granada 24V Cosworth (BOA)
« on: September 08, 2006, 09:34:54 AM »
Firstly in the U.K we call this car the Granada, it only changed to just Scorpio in 1995 which I know is all very confusing as even Ford forget this fact sometimes.

Does the 24V qualify for the section?

Well I think it does, the engine turned what was a rather boring under powered large family car into something a bit more exciting. A historic event in many peoples eyes  

The engine was the result of 3 years work between Ford & Cosworth. The Ford engine code is the BOA.

The orginal concept was a Brian Hart creation but when Cosworth bought them out they got the design.

So we have a engine that was first designed as a racing engine, then re-designed by a very famous racing engine specialist & then fitted to a Granada.  

The engine was tuned for high speed cruising, emission excellence & smooth running to suit it's new home but was still very much a high performance engine stuck in a heavy restrictive car.

Stories of it detuned are simply not true.

In the interest of emission laws & reliability a engine will always loose a bit of go but how else can Ford market the engine, it has to meet certain world market targets.

When first produced the engine was one of the most powerful sub 3.0L N/A engines in the world make no mistake.
It was code named the FBA by Cosworth who later developed a racing engine called the FBE which used the same block & heads.

With simple mods the engine can see big gains in power as the basic package is sound.

A N/A engine can make 350 bhp if you want to spend lots of money on it which is probably it's limit N/A.
To boost it is far cheaper for the same power level & beyond, infact 600 bhp is possible & probably more  

Below is the press pack that introduced the Granada 24V to the world

In the 2nd brian hart engine picture it states!

"Brian Harts 24 valve twin-cam conversion of the 2.9-litre Ford Cologne V6 engine featured new aluminium cylinderheads with camshaft covers carrying the logo's "24v DOHC" this would not survive the prototype stage

but maybe at least one did,!!! as we all know!

The same head design was originaly used on the early 2.8 engine, again with the same logo "24v DOHC"
untill the Hart company was bought out by cosworth.
The camshaft covers where machined and ended up as you see here!

So realisticly if you own a BOA what you really have is a Brian Hart engine !!!!!!
tho the later engine was re-designed by Cosworth I believe.

Tone what I would say is if you:

Own a BOA you own a Brian Hart idea that cosworth made into a marketable reality.  
If you have a BOB then you own a engine that Cosworth was not given time to finish.  
A FBE then your just lucky & if you have a FBD then pictures of it would be nice.
