Hi!

I am not going to modify the engine of the Tempra I use, since it still is owned by my father and for him it is just fine as it is now
However, being no engine expert, I would like to get an idea of the power (and fuel consumption) increase that there could be by making some modifications to the carb setup.

The stock carb is one double barrel Weber 32/34 TLDE 23. I suppose that, by changing the intake manifold, it would be possible to mount another one of these, so that each cylinder would have its own barrel. What about this configuration? I think this would be difficult to achieve because a quite big carb "cover" with air filter would be needed and maybe the hood won't close...

Otherwise, what about exchanging the stock carb with a bigger one, while maintaining the one double-barrel configuration? I read on Wikipedia (http://en.wikipedia.org/wiki/Fiat_SOHC#Carburettor) that Weber 40 DCNF could be used. From what I understood it is a quite "powerful" part! In this case, if the size is not much bigger than the original carb, probably the hood would close and it would be possible to maintain the stock air filter.

Can you give me a rough idea of the performance increase (if any) of the two configurations listed above? What about fuel consumption increase in "normal" (not pushed to the limits) driving? The engine is 1581cc, 86 HP (62 kW).

Probably a big part of what I wrote is pure nonsense, but who knows...

I moved this thread, still with no replies, from the Tempra section to a more generic one, since its nothing strictly Tempra-related. Hope to get some answers here, I am quite curious

This information could benfit both Tempra and Tipo owners.

I know that a mate of mine said that is is possible to add a motorbike carb to each cylinder separately, but it is a looong modification AND will drink petrol like a russian at the vodka

adding bike carbs to a 1986 micra got like 25hp, you can buy the manifold with carbs for a reasnable (ish) price, shouldn't use loads more petrol

Wow, 25 HP out of a much smaller engine!

Another carb-related question, the one in the Tempra is Weber 32/34 TLDE 23. Does the number "32/34" mean that it is a "progressive" carb? What about that "23"? TLDE should be the model and it seems it is not well known since almost no web site has information about it
