SU HS4 (1.5") Ram Pipes
Ram Pipes? Velocity stacks? Carburetor trumpets?
No matter what you call them they are undoubtedly a way to add horsepower. These ram pipes are designed to fit the SU HS4 carb. They are designed with an exponential internal curve to reduce any shock waves in the induction flow leading to standoff. They have a large radius bell mouth with an almost 180 degree “roll back” to give the best possible flow, a huge advantage over using no pipes or the cheap rolled steel items.
Lightweight
strong
temperature, oil and fuel resistant
Large radius opening
180 degree roll back bell mouth
NOTE - These ram pipes do not include the fixings or gaskets.
Doesn’t quite fit your purpose?
The CAD file of the ram pipes from Matt Black Prints are fully adjustable and we are more than happy to design and print custom ram pipes. All parameters can be changed as well as mounting options.
