The new housings are turbo,
Finn. Yes, the NA's has splitters which reduce the noise level by 8 db
according to the Mazda data I have seen. However, I am also certain
there is some power loss with the splitter given that level of noise
reduction - probably more at the higher rpms than the lower.
I'm with you
Ed. Someone would have to show me a dyno run where nothing was changed
but the rotor housings. Until then, I believe there has to be a power
loss caused by the splitters.
