Cornetto venturi FABBRI RACING per carburatori maggiorati - alluminio CNC anodizzato nero

Descrizione

This is a CNC induction collar for large bore carburettors such as Dell'Orto VHS 34mm-39mm, Dell'Orto PHBH 28-30mm, Mikuni TMX 35mm, Kehin PWK38mm etc.

Comes supplied with 2 sets of small Allen screws for fixing to the carb. The internal diameter is 64.5mm, external 88mm and depth 18,5mm. Made from high grade Ergal, these collars are based on those used on the Casa Lambretta Racing Team scooters. Although these were initially designed primarily as a custom part, rather than a performance enhancement part, we have actually seen that max power output is increased by 0.5bhp with one of these fitted to an engine!

Please note that on some carbs it may be necessary to remove (file away) the outer lip as indicated in one of the pictures for fitment of the collar. If you wish to fit the collar to a Dell'Orto PHBH carb, then you will need to utilise a plastic adaptor ring
