i was looking at the pic of your oscai sticking below the splash guard. have you driven it with just the tube pointing down and with the vacuum scoop removed? how much of a difference does that attachment make?

 

I have only compared my current set-up to the stock set-up so far. When I have time I would like to make the comparison you mentioned above. My method of testing is quite unscientific (involves repeatedly testing time to 100kph on same section of highway) but it gives me an idea of performance when tested over a number of differant days. If I take the forced induction device (rigid vacuum attachment) off I'll let you know. In case you're wondering, the OSCAI/K&N drop-in set-up has made an average 0.3sec differance in my recorded times when compared to stock.
