INJECTOR MOUNTING

 

The 803 Series throttle bodies are designed for applications where the fuel rail is mounted to the manifold, cylinder head, or in conjuction with an external injector mounting kit.  Fuel injectors are not mounted to these throttle bodies, and are generally mounted directly to the cylinder head, or an external injector mounting system.

 

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 WITH THE HIGHEST QUALITY STANDARDS IN MIND

 

Years of development has lead to constant improvement right up until today, where these 803 Series throttle bodies are now considered the industry standard by many engine builders and engine tuners alike.

 

Track racing is one of the most demanding environments any fuel system can be exposed to.  Using anything less than the highest quality intake components may lead to not only a disappointing finishing result, but also engine damage.

 

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.
