There’s a reason not many people do it.

This isn’t 1:1 comparison to exhaust chambers. The gasses in the exhaust are high pressure. Good density means efficient and fast wave travel.

The intake is being evacuated constantly. Very low pressure. And the wave isn’t the exploding mixture of fuel, just that very low pressure column of air bumping into a closed reed or piston skirt.

I think the greatest good of a tuned intake length is to, at a min, not let that weak ass return get OUT of the intake before the next signal pulse pulls the air and fuel back in. And, If I understand it correctly, that’s mostly at low rpm where most of use tune our clutches to stay clear of.

Top it off with the majority of people on mopeds tuning with butt dynos, and it’s hard to get an accurate picture.

I will throw something together this weekend and share too. Can’t go wrong if it’s all for fun.
