Question:
I have got a Hayabusa 2004 Gen 1 engine with nothing special on it at the moment. Is running the 4 short airhorns is a better option?
Answer:
The use of a combination of air horn lengths has a tendency to smooth the torque curve, the longer air horns promote lower to mid-range torque and the shorter air horns improve the upper mid-range torque to peak bhp. If your engine is solely being used at higher rpm on the standard 1299cc engine, then potentially 4 short air horns will be the preferred option.
If you are using a long stroke engine in the future, then 4 longer air horns would be the best option for that engine because the engine does not rev as high.
