I get it..The part I don't get is how two guys each with a 102 and a 106 parked side by side at a C&C could have a meaningful exchange of how to "soup" up the performance of one v. the other, other than suspension settings and tires and make any sense of it... common basket of interchangeables aside. My comments are directed at the heart of the original poster's question...It's da motor. I think it has to be 2600 specific to have any credibility.

Pete,
If I might say, that is a little harsh...

The 2600 Sprint was run by the factory as a full-supported Works team in '62 to '64 before the advent of the Giulia ti and the GTA. It competed in the European Touring Car Championship, driven by works drivers such as Andrea de Adamich. Later on it was raced by Works-supported privateers with moderate success in its class, occasionally beating Jag Mk 2 saloons. Finally it enjoyed a lot of success in international rallying including the Tour de France.

Now, no-one who has raced one will claim that it was the ideal, well-balanced Touring Car, but it was a useful tool in competent hands if a little heavy on the turn-in. Today, with Weber 45s, a modern cam (pref an RJR profile), attention to the cylinder-head cooling and some handling tweeks plus, if affordable, a c/r box and an LSD, it can give a good account of itself.

I was 47 when I started racing mine, just the right side of 70....

Racing 2600

Erich Stahlman is building an all out race car for his father. A 2600 Coupe. Car and engine are gorgeous. I`ll try to get him to post a pic of the car & engine.

Richard,
I would be delighted to see something of Erich's 2600. He first mailed me in 2005 about his project, so it has been a fair old time in the making ....

Now I've worked on and driven Jaguar Mk 2 saloons and they are very rapid ...

So now I'm confused; takes a good car to beat a Jaguar Mk 2 and they were good race cars in their day.

FWIW, driving on 165-400's, the late Adrian Ratcliffe was able to give an Autodelta 1300 GTAjunior driven by a very competent and quick driver - albeit may be not over the top like Adrian - and a lot of other cars a hard time at Westwood (the circuit where Gilles Villeneuve had some of his Formula Atlantique successes - it sadly no longer exists and has become a housing development since) driving a 102 2000 Bertone with a spool and a prodified 2600 engine that he used to take to obscene rpm ... He ended up cartwheeling that car - often fondly referred to as Ms. Piggy - in an incident that involved wildlife IIRC.

Pete,
Here's the clue : Alfa 2600 Sprint, no serious development in Historics over the last 50 years..... Jag Mk 2 saloon, practically continuous development since early 1970s to 2016 ....

The pace of Jag saloons today is near-enough supernatural, but back in the 60s, on a long circuit such as Spa, 2600 Sprint was over 2s a lap faster ! Happy days.

The Jaguar I worked on was not a race car but a dead standard road car, a 3.4 MkII auto, and it was quick in a straight line. Note I was only about 16 so 32 years later might not feel as quick

But yes Jaguars in historic racing are making huge hp and revving way higher than they ever did. I believe Cosworth did some work on them.

So you want to help your friend make his 2600 faster...I found the answer today totally by accident. Pay close attention to this video clip or you may miss it:

FYI, the segments concerning the 2600 engine are at about 6:00 and 11:45 in the video.

Thanks Ruedi, that is one sweet sounding 2600; I have to admit it myself.

Try this link

or this


Amazingly there are two alfa romeo "race cars' on car and classic at the moment

ALFA ROMEO 2600 SPRINT 'COMPETIZIONE' - Ex Targa Florio For Sale (1965)

ALFA ROMEO 2600 SPRINT 'COMPETIZIONE' - Ex Targa Florio For Sale (1965) on Car And Classic UK [C813364]

At 28,000 compared to similar prices being asked for original cars , you may as well buy this one and avoid all the development costs.


or you may recognise this one at an optimistic 50,000

Alfa Romeo 2600 sprint FIA Racecar For Sale (1965) on Car And Classic UK [C802278]

N.B I have no interest or connection with either car

Thanks, redmerlin,
i would be very interested in your weber intake manifold for the 2600 engine, as i've already bought a set of rebuilt 45-dcoe-9 webers. Please let me know how to contact you further re. This. Would it be possible for you to post a photo file of it here?
Thanks,
