Carburetor Size
Posted: September 17th, 2008, 11:03 am
When I updated my engine from 1600 cc's to 1915, I was told by the builder of my cylinder heads that if he were building the engine, he would build it using a 44 mm weber carburetor. I have a 40 mm weber and had planned this winter to update to a 44 mm and dyno test the improvement.
I talked to my local carburetor expert, yesterday, and he said the 44 mm carburetor would hurt (drown) the low end performance. Now, I'm unsure what to do.
Does anyone use a 44 mm carburetor? Has anyone dynoed their engine (with a 40 or 44 weber). Has anyone done a side-by-side comparison of 1915 cc engines with the two carburetor sizes? How about a 1600 cc engine comparison?
I'm looking for data.
thanks,
Mike
