Real Fiero Tech

How exactly are you supposed to get an air filter on the inlet? Is there at least a screen over the opening? I can't tell from the photo.

Late timing is like richening the mix, advanced timing is like leaning the mix.
Turbo tuning generally pulls advance out, but pulling too much is worse, because pour-in bottles of octane booster can't fix that.

No filter but I do have a metal screen over it for some protection. The crossover is a WCF piece and probably isn't supppose to have that big of a compressor housing in that spot,

When I said it might be pulling timing, I meant the knock sensor might going nuts from the loudness of this thing, but I don't data to back it up at this time without any logs... so it was just a thought to look into when I get there.
