I have 1.6 liter '87 BMW. I am having trouble with it's Pierburg 1B2
carburetor (cold start and idle). Replacement parts are ~200 euro. In
local Weber shop I was told that I can replace it with Weber 32 ADF
(can anyone confirm this?) for ~300 euro.

So now I have:
75@5800 [hp@rpm], ~80 [hp/ton], 110(80)@3200 [Nm(lbft)@rpm]

With new carb I should have:

90@6000 [hp@rpm], ~100 [hp/ton], 123(91)@4000 [Nm(lbft)@rpm]

Currently I feel lack of power during acceleration. I also have Audi 100
2.3 liter:

136@5500 [hp@rpm], ~100 [hp/ton], 188(139)@3000 [Nm(lbft)@rpm]

I am not a sporty driver, I drive most of the time in slow city traffic.
I was wondering how would compare new BMW setup with Audi with the same
hp/ton ratio, but different torque. I am not talking about 0-100km/h
(0-60mp/h). I am interested in acceleration in third gear during
overtaking. I knew that it is not just the meter of power and torque,
there is also a gear ratio... but I think that power/weight and torque
are the decisive ones.
