4x Clamp Rings with Inside Diameter 47.2mm and Outside Diameter of 75mm. 8x M6 Button Head Screws. This kit has been designed for anyone running the bike throttle bodies without the original airbox arrangement - particularly in kit or modified car applications. With the appropriate baseplate can be incorporated into the kit if desired. For further information and fitment options.
Please measure and ensure your throttle bodies have an outside diameter of 47mm at the inlet where the clamp rings will slot over. This kit may be suitable for other throttle bodies with the same measurement.Below are links to two different engines fitted with two popular bike carb kits (one 1800 zetec with R1 Mikuni carbs, one Ford 2.3 Duratec fitted with ZX9R carbs). The lower lines are both carb sets without trumpets and the higher lines are when fitted with our 50mm trumpets. In both cases significant performance increases (typically 5-9bhp) are seen. When the carburettors are fitted with our trumpet kit.
Additionally the torque curve is seen to be much smoother. Note that the Duratec is making peak power very low in the RPM range due to a very restrictive exhaust soon to be replaced! , but the effect of the trumpets on engine performance is clear. We see so many bike carb conversions running without any trumpets (bike breakers often remove them along with the original bike airbox) - ALL of which would see the benefits highlighted below, probably the cheapest power you can find!
