Hi guys!

Havn't been around for long time! I am DIY a very similar cold air intake system like the RB my self out of fiber glass. I was going to use carbon fiber but cost 400 times more!! So I make do with glass..hee :p I will be finishing soon and I will post it with photos this weekend!

I think RB one will work very well because I have tested on mine - the card board prototype. I place only the side of the mouth against the fan and its already blowing really well out from the other side! And it blows even greater when I place the whole intake infront of the fan. So I am expecting this is going to be a very true cold air intake because, fan speed will never be as strong as driving head wind rite? At least thats what I am thinkning.
