HP/kW Ratings vary from engine to engine. The power ratings given here are only a guide, and are not absolute power ratings. Engine power is determined by intake, exhaust, cylinder head design, camshaft design, compression ratio, fuel type and quality and many other factors.
45mm - 54HP/40KW* per throttle.
50mm - 72HP/54KW* per throttle.
55mm - 84HP/64KW* per throttle.
*This number is a guide only and should be used in conjunction with real-world experience.
EFI HARDWARE PRODUCE 6° THROTTLE PLATES
In the past, 12° throttle plates were the industry standard. The problem with 12° throttle plates, is that as the plates are moved off the closed position, the change in airflow is huge. It makes it very difficult to drive smoothly at lower throttle openings.
At EFI Hardware, we only use 6° throttle plates. This improves off idle and cruise driveability making your vehicle far more enjoyable to drive.
PROFESSIONAL GRADE MANUFACTURE
Manufactured from 601 Cast aluminum and heat treated before being CNC machined.
The butterflies are measured for each bore & precision machined to a 0.0005"" tolerance.
Butterflies are secured to centreless ground brass shafts with split screws to ensure reliability and serviceability.
All are fitted with bearings rather than bushes to eliminate axial shaft movement.
Low stiction bearings for sharp throttle response.
We now recommend
and use SKF bearings.
