Ram pipe

42.25 GBP
Ram pipe
for SU-H4 and HS4 carburettors. 1.5" deep aluminium funnel with gauze and 1.5" connection width.

Ram pipes are increasingly often seen in motorsport and competitions, and for good reasons. The air horn optimizes the flow of air streaming in front of the carburettor. The ram pipe allows tuning of the entire engine characteristics. Due to the parallel flow, the funnel has an influence on the speed range and thus on the power. A short funnel ensures low torque but high revving. The longer the funnel, the more torque the motor develops in the lower rev range, but at the same time the maximum possible RPM decreases.
