i have managed to get hold of 4 40mm dellorto drla and will be buying an inlet manifold for them,
what sort of power gains will i see over a weber 500?

Whats the engine spec??
The Weber 500 will perform pretty well from a 3500 right up to a 4600 with the right jets and needles!!

Very little bordering on zero would be my estimation - the 500 is capable of flowing enough air for some very high horsepower figures.
Unless you have modified the engine to make some very big numbers its just looks and the joy of keeping them all balanced and feeding them with loads of fuel.

top end power? probably nothing....
Mid and low range torque? a BIG difference
Fuel economy? if they are set up well, then an improvement. if not balanced properly? then pretty poor.
I have also got a set of 34mm drla's for my 3.5 I am building. A lot of hassle I have heard, but if you like pain and also a lot of torque, then they are brilliant.
