Does a GQ TD42T injector pump flow more than a non turbo injector pump?
the turbo pump has the boost compensator,is this the only differance?

Cheers

ve10 so on for 10 mm and ve11 for 11 mm

There was never a factory turbo pump for Gq patrols. All n/a engines and some early td42t engines ran 10mm head and rotors, later td42t were 11mm.

Fitting a boost comp allows the pump to be tuned and set correctly for given boost pressures and also stop excessive smoking down low.
