Bottom line is that, at best, a decent panel filter will contribute to, what, 1-3 bhp. And that's if you get 'lucky'.

They're a bit of a moot point on a turbo car in that respect, as the turbo is effectively blowing a hurricane through the engine - so, by proportion/comparison, their actual contribution to the overall airflow effect is tiny.

As above, they're more relevant on NA cars with relatively modest outputs - where every extra bhp gained is welcomed.


In my considered opinion.

Has anyone tried a back to back dyno with no filter in the box at all? also a fair test would be to measure VAC in the inlet pipe between turbo and maf. less vac= less restriction.
