Cooling is a major consideration too.
Ok, I ordered some rubber fins for the engines. Can’t say it made an obvious difference, but every little helps.
Still to get the floor anti vibration mounts, so there is still hope. What I did notice was the difference in volume when I removed one of the standard air filters. Massive increase in noise.
I will need to get myself to a local breakers, and get a decent air filter box, as has been suggested. If I can get as much of a reduction from the car filter, as the standard filter gives, then I will be a happy bunny.
I tried a large VW Polo airbox on my 14cfm parallel twin belt drive compressor expecting a reduction to the induction roar and it made little to no difference. Quite disappointing really, I should have persevered with it and experimented with different induction fittings and tubes.
try a smaller filter on if its big your going to hear more noise
Induction noise is a science in it's own right, most of the noise seems to come from the flat end of the filter and what feels like pulse reversion hammering on it.
