Who has heard of or used the arc flow intake, if so how good is it? And has anybody head anything about the Aurora MST turbo? Also who uses the FASS system, is it any good and how does it actuall work? does it replace the pump inside the fuel tank or is it external? And where should i mount it, i use the truck off road in real muddy conditions.

The arc flow is very similar to the banks high ram intake horn, and will do little to nothing for extra HP, it just looks cool.

Last I hear, the MST was still in devlopment, and if it ever hits the market, it will be exspensive. Save you money and run a good single from either Industrial Injection, or a hybrid from some one like JR Adkins.

You don't need a FASS on a 12V truck, the stock mechanical lift pump will easily support the amount of power you wil be running.
