Lola T140 engine question

[Reto Kuprecht]

Dear Lola specialists

I have been looking at pictures of the ex Jerry Hansen/John Mahler T140. As I cannot see the usual IDA48 carbs - could this engine have been fitted with a cross induction manifold and DCOE carbs? Difficult to see - but perhaps anybody would know. In general, I would like to know wheter any of the early F-5000s used cross-induction manifolds. Later designs of course did - with the Alan Smith and Morand slide valve/fuel injected setups. Any insight into this would be most appreciated.

Here's the pic out of oldracingcars:



And, for your late evening enertainment, here's a pic of M10B 400-05 in its current configuration. But I have changed the wing now to bare aluminum, and made other smaller changes to represent the car as it looked during late 1970 season.

Regards, Reto

Can't see your photos, only "?" marks...
There are photos on this site that show F5000 cars with cross carburetors (#1), fuel injection (#11) and dig a little bit and you'll see a club raced T-140 with single 4 barrel carburetor!

Thanks a lot for your feedback. I'll look up these photos - in "myf5000" you're saying?
I did manage to get pics out of my picture files into the reply - but then as I post the reply, the pics are gone. I think I need to take a course on this...
Best regards, Reto

Well, here are the pics finally:

Reto:
Those are lovely. Is that you in the McLaren? Nice shots.

[allenbrown]

Yes they are nice shots. I do believe I recognise one of them. Its usual COPYRIGHT message seems to be missing however.

John, would you be so kind...

(Allen, have added note on the post #4 above - hope that is OK - JT)

Allen
Mea culpa - I really apologize. I was so excited to finally have managed how to post pictures that I forgot about the copyright issue.
The point was to show one example of an F-5000 with an engine setup I cannot identify. On this #8 - is this a chevy with a cross ram manifold and DCOE's?

And yes, the guy in the McLaren is me - looking cool at last years Jim Clark Revival in Hockenheim. Actually this wasn't so cool as I ran out of fuel right before the pit lane entrance - so I was rolling in very silently and somebody could take this photo from above...

Definately 48 series Webers on a cross ram, I know Pete Jackson made such a manifold (probably along with some others). Most people didn't care for them much because it made "running the valves" much more difficult. If I remember correctly the carbs absorbed so much more heat in this setup that any prolonged engine idling, (without the car moving) made them prone to vapor lock. The thought was that the cross ram had such a nice curve into the cylinder heads that flow had to be better, but I don't think anyone could document any improvement and the negatives overcame any percieved improvments.

John Surtees won the initial Can-Am series in 1966 with an "extended" small block Chevy, if memory serves, from TRACO with side draft 48s.

[Reto Kuprecht]

Thanks a lot for clearing up this issue. I certainly see the disadvantage of side drafts positioned just above the heads and exhaust primaries. Perhaps less of an issue on the moving car - but still no real reason to switch from down-draft IDAs...
