This kit may be suitable for other throttle bodies with the same measurement. Why fit velocity stacks or'trumpets'? A radius at the inlet of an inlet tract serves to smooth and even out the flow into each intake runner. You will note that any manufacturers standard equipment will feature such a radius for this reason. Without this radius power and torque can both be negatively affected.
Additionally when tuning for power increases a longer inlet tract (the distance from inlet to back of valve being the important length) has been found to be extremely beneficial, especially on a lower revving car engine. 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! These kits are in stock. See our other items for related inlet and exhaust parts.
