So a friend of mine is about to re-install an old (but rebuilt) 1.6 Kent motor into his MK1 Cortina. I'm not sure on the specs, but it has a 2-barrel manifold and he's looking at upgrading from the 32/36 DGV he had previously, to a 38DGMS, so he probably has more than 100hp.

The 32/36 represents the primary and secondary throttle diameter (in mm), and it has 26/27mm main venturis respectively.

I was wondering what can be done to increase airflow without changing to a different carb type, as the 38DGMS opens both throats simultaneously, so he will most likely lose drivability.

Looking at the carb, it appears that the support legs for the boosters can be streamlined somewhat, and the boosters can be knife-edged. The booster design itself is... poor. Can they be internally modified to increase flow *and* increase or maintain vacuum signal?
