AI Weber Carburettor Conversion Kit for
the Sunbeam Alpine Series I-V
and the Sunbeam Rapier Series III-V
Not just a collection of off-the-shelf components, the Weber 32/36 Carburettor conversion kit for the Sunbeam Alpine was developed as a project in partnership with Webcon UK Ltd., carefully selecting and tuning each component. The inlet manifold with its curved runners, unique to Alpine Innovations, is mated to the genuine Weber 32/36 DGV carburettor with an insulated spacer gasket. The unique jetting of the carburettor was established after 3 days of testing on Webcon’s rolling-road with the resulting customisation optimised for performance, fuel economy and drive-ability. A plenum chamber, ducting hose and K&N filter enables cooler air to be drawn into the carburettor, rather than air preheated by the exhaust manifold and engine. To complete the kit is the stainless steel throttle linkage, fuel filter and the necessary studs, nuts, washers, hose, clips etc.
An original Sunbeam Alpine Series 5 with twin Stromberg carburettors was used as the test car and testing of the original twin Stromberg setup provided a useful baseline comparison figures. The Weber Conversion was shown to outperform the Strombergs by 17% in like for like comparisons on the rolling road.
Note: This conversion kit is suitable for the Sunbeam Alpine Series I-V and the Sunbeam Rapier Series III-V (with minor adaptations). For Sunbeam Rapier Fastback, Hillman Hunter, Humber Sceptre and Singer Vogue please see our other kit offering for these models. Neither kit is suitable for engines with the cast-iron cylinder head.
