1.8 MGB B series Supercharger kit
Vmaxscart B series MGB supercharger kit based on our best selling A series kit, Complete with pulleys , belt, supercharger, pre jetted and modified DCOE carburetor, decompression plate, air filter and gaskets etc. An easy DIY fit and adds around 35 bhp and 35 lbs ft to what you currently have. Our CNC 6061 billet alloy inlet manifold is used, giving rigid mounting with high airflow, this has a water jacket incorporated for charge cooling to suit hotter climates ( an additional pump, reservoir and radiator is required- £100 or it can be used without this being connected).
There is a choice of colours available or you can supply your paint code to be matched.
The kit is ultimately designed for standard or mildly tuned engines, in rev ranges 1200-5000rpm . A decompression plate supplied (stainless shim fitted between two Payen composite gaskets) in the kit to reduce the compression ratio if your engines compression ratio has been increased. A new 6061 alloy front pulley provides a vee drive for the existing water pump/alternator and an extra drive for the supercharger, these two opposing belts give acoustic damping to delete engine harmonics.
Will it fit all B's? ; Earlier cars may need the tappet chest breather canister modifying if fitted (some early US spec cars have this) . Engines with high performance high lift n cams are less suitable due to overlap, but still can be used.
The kit is pictured below on my inca yellow1978 MGB roadster, this was used to tune and develop the kit in 2020.
