Mine was 236 bhp with Gtec 1 and 1.2 bar. That was with a cone filter that was much too small for the car so now it is probably a little more - 245ish? Interestingly, the fuel economy was excellent with the too-small filter - much more thirsty now
Erm no Neil totally wrong I'm afraid mate.
On your/my 20vt I took the filter off as I heard a myth saying the filter was too small whilst on the dyno and it made the exact same power as with the filter on.
On a standard turbo at 1.2 bar the filter size doesn't matter at all. If you're getting into the realms of hybrid turbos and 300bhp + then the bigger filter is better!
I have the same filter that was on that car now on my 16vt and did the same test again and again same power.
Please folks correct me if I'm wrong but I'm sure a free flowing filter is a free flowing filter?
