AT Power’s DCOE throttle bodies are a direct replacement for Weber DCOE and Dellorto DHLA carburettors - the classic route from carburettors to modern electronic fuel injection (EFI). The fixing bolt patterns match the original carburettors exactly, so they bolt straight onto standard DCOE-pattern manifolds with no re-engineering.
Carb looks, EFI performance
Each twin round housing is CNC-machined in-house from aerospace-grade 6082-T6 billet aluminium and fitted with AT Power’s patented Shaftless knife-edged butterfly - no spindle across the bore means measurably better airflow, sharper throttle response and more power than either the original carburettor or a shafted throttle body. Bore sizes run from 36mm to 48mm, in 2-cylinder, 4-cylinder, 6-cylinder, V8 and V12 configurations.
Configure it your way
Options include cable or Drive-By-Wire (DBW) linkage, rotary contact or Hall-effect contactless throttle position sensors (TPS), billet extension tubes and ram pipes in a choice of lengths, one-piece billet fuel rails with brackets to suit a range of injectors, vacuum take-off fittings - and 20+ anodised colours to make it unmistakably yours. To complete the installation we supply fuel injectors, air filtration, motorsport cables, tuning aids, fuel pressure regulators and ECUs.
