When you state you cannot get full power, can you be more specific?
When I had the 30mm venturis in my sidedraft DCOEs, there was no increase in power above 5500 rpm. I moved to a 34 mm venturi, and she now pulls well up to redline.
@Ohmess
seems right if you see the diagram ... you have 500 cc cilinders ... if it is still a 3 liter ?
Perhaps 36 mm was even better but a spec smaller gives better torque .
Yes Belgiumbarry, and my experience is also that the slightly smaller venturi provides more torque lower in the rev range. Here again, my car is not a racer, it is a driver.
