H22, I think I'll pick one of these up before I get an NA tune. They're like $20 on Ebay.

Support someone that put his own knowledge and time into designing something that actually works. Get the BPi.

H22, do you have the link to where you got the AUT plate? How was the fitment? I am thinking of going to get the bpi stack as well.

I bought the AUT plate on ebay. The fitment was horrible. I had to do a LOT of trimming with my dremel to make it fit right. Their's a huge thread on where to buy the AUT plate, I believe in this section.

Velocity stacks work on any engine to help straighten out the air flow and it increases the cfm a little.

Interesting. In the JDM tuning section, I read some big JDM baller company uses dryer hose for the tubing because they say it "swirls" the air and its somehow more efficient.

after that bunch of BS dont buy anything from them, ever.

swirly air = good mixing but slow moving.

You want it to swirl IN the chamber but as smooth as possible until the valves

I've never seen a dyno that showed a decrease in power from using a velocity stack(s). Just look at all the car mags that build engines and you will find that most use some sort of velocity stack(s) when its on the dyno.
