The small cc-differences in my notes are mostly based on different heads I think, personally never heard about a 2,5 ltr. in those.

 

My memory on those cars is a little fuzzy, but wasn't it the D23 that had the V-6? I also recall they swapped the engines around all the time - I don't believe anyone knew which engine was in which car at any certain time during their competition days. But pretty sure only V-8's in D24. The 2.5 was the Formula 1 engine which could have found it's way into one of the sports-racers. Lancia was as bad as Maserati in keeping accurate records on the 1950's era comp cars.

John,

 

I was not allowed to open the bonnet on the D24 to have a look. Most sources say a V6 from 3.2L to 3.75 V6 in the final version of the D24 and the successor D25. My friend who built the D50 believes that the V8 engine was designed to replace the V6 and allowance was made for larger V8 engine sizes than the GP 2.5L. He thinks it was used in the D24 at some point and some other sources agree with that. However I can find no evidence it was ever raced with the V8. The V8 was only designed with a rebuild life of around 450 to 500 miles, which would have been a bit short for a sports racer. I have been doing a bit of research on this in the last few days and I have managed to find a drawing of the D24 V6 engine, which I post below. I believe it used the same block as the Flaminia but with twin overhead camshafts.

 

Of course, nowadays with modern bearing materials and better fuels, these engines can be made more reliable or to produce more power. My brother’s 1938 6CM Maserati GP Voiturette was producing well over 250HP from a supercharged 1.5L engine, which was nearly double what it was making in period.

A bit off topic but because John mentioned Maserati:

 

Today a young Merak driver stopped at the gas station. The car wasn´t in good condition, engine sound was bad and a lot of smoke even while he filled the car and engine was out. I couldn´t resist to grin. So much noise for so less power with all the Citroen SM issues, poor boy. Anyway nice looking of the "poor mans Bora", really like it. Could bet it was the "italian tax version" with 2 ltrs. - downsizing before modern turbos ;)

Wilson, my friend Bob Sutherland (sadly deceased) had a 1930 8CM in which I had the honor of being the "riding" mechanic during one leg of the first Colorado Grand. Bob was a rather large individual and I had to ride with my right arm around his shoulders in order to fit! My job was to keep the fuel pressure maintained by use of a hand pump. Anyway, by the time we finished our stint the floorboard was awash in oil as the engine used no gaskets, mating surfaces being hand-lapped in, and leaked copious amounts of the liquid. I have many pictures of this excursion but they are all slides and have never been copied into digital format. When we finally halted Bob had to put the better part of a case of oil in the oil tank! He raced this car in vintage racing - we were running on pump fuel and limited on rpm because of it, but Bob said for racing he used racing fuel and the engine wound out quite nicely. I wonder where it is today?

In 1982 I went to look at a Bora, which had been repossessed and then subject to a court case. It had sat unmoving for 4 to 5 years outside under a cover and none of the high pressure hydraulics were working, although we managed to get the engine to start. This meant that you could not even turn the steering wheel, depress the clutch or move the pedal block which was on hydraulic rams. I made the very sensible decision to steer well clear, even though it was very attractively priced at just £4000 (and I could probably have got it for less) and bought a high mileage Ferrari 365GTC/4 instead, which then rusted at a quite alarming rate.

Is this D24 the car I might have seen at 'Race Retro' a few years ago? I remember then an awful lot of people were saying it was a 're-creation' as none were thought to exist? To me it had the patina of a well used old car, but re-creations are not always contemporary and a response to today's premium prices and race scene.

Steve,

 

I think it is fairly clear that this is one of two remaining originals and is the Juan Peron car (the other is in the Lancia Museum and I think is a non-runner). It had been badly/cheaply restored, if the paintwork was anything to go by. Designed to be looked at from some distance. Going by the paintwork, I hate to think what had been done to the mechanicals. I don’t think it has had a great deal of use so unlike many other heavily used historic racers, it would not be a grandfather’s axe (two new heads and five new handles). In some cars all that is left of the original is parts of the chassis, the gearbox casing and back axle casing. All the rest has been replaced, sometimes more than once.

Wilson, there were many of us at the time dreaming of a Bora without the Citroen hydraulics. Maserati even made a racing Bora, (perhaps for a customer for LeMans?) and naturally it dispensed with the Citroen juice, but it was never publicly raced, although those who test drove it said it had much potential.

I suppose if one so desired and was just dying for a project, he could mate a rear body and engine assembly from a Bora to a Merak and fix what was inherently wrong with both cars!

Sorry for the delay but I found a new contender.

Sorry,

 

Not Nardi or HWM. It's got a 6 cal. engine.

 

A bit more generous crop maybe.

I was going to say Frazer Nash Le Mans Replica but the vertical shock absorber is wrong. Then I thought of a Connaught but they are torsion bar not transverse leaf. The independent front suspension looks like French Dubonnet knee action suspension, so I am going to go for a Delahaye 135S.
