HP RATINGS

 

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.

 

40mm - 45HP/34KW* per throttle.

 

*This number is a guide only and should be used in conjunction with real-world experience.

 

BUILT FOR THE STREET

 

For improved engine idle quality, these throttle bodies are supplied with individual adjustable Idle Bleed Screws for each throttle allowing you to balance the air flow to each cylinder at idle.

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.
