make sure you get more length on the piping to simulate cold air as a test also.

I've done this test also and I gained more power with a cold air+ velocity stack... I actually gained close to 20whp more, and 15+- foot pounds of torque. Better low end, and top end. the length of piping helped increase velocity. What I ran was a 3" tapered to a 3.5" to a velocity stack all conical transitions with expanded piping welded.

will do, i just want to see if there is anything i gain from switching over to a bigger intake, and i will be keeping a short ram becuz i dont have splash guards....

I don't have splash guard either, but I run a front splitter, which I recommend you do too. You'll like it in the high speed sweepers, banks, etc. It really helps, but you have to stay on the gas for it to actually work.

My friend was talking to me about this the other day. Cause he was suggesting that I get a Velocity stack and maybe switch to 4" piping. From my v2. Im interested in seeing how this turns out.

I have a feeling this will work better on a highly modified car than one that is relatively stock.

4" piping isn't a joke... Saw some yesterday that was being mocked up for a K-Series hatch, it made me look at my V2 and literally say damn this looks small...

yup it will prolly take a week to get to me but the good news is this is a DIY kit basically but you will need a small battery or relocate it, i am optimistic but its basically a gamble but i hav spent money on mods before that basically made me slower so this type of testing is no biggie

So with this are you running a filter or just a velocity stack?

I buy alot of my piping from VotionSpeed.com - Silicone Couplers, Reducers, Turbo Intercoolers, Water to Air Setups, Bosch Pumps, Aftermarket Car Parts They got some good prices. If you need more piping you can check them out.

These prices are all for 1 ft sections.
4" straight is $15
4" 45 degree is $20
4" 90 degress is $20
4" 135 degree is $30.. not sure if this will be of any use.

A 2 ft section of them is
4" straight is $20
4" 45 degree is $30
4" 90 degress is $30

took some pics of the 4" to 3.5" transition reducer coupler i made a mistake and should have ordered a 4" to 3.25" reducer but i made it work for now and it will be good for when i add a larger throttle body in the future. Anyhow i took some measurement so we can get a better idea of wut we are lookin at here, you can see in the first pic the size difference compared to my old intake

That large of a gain over a 2.75-3" cold air?

that large of a gain if the intake was a 4 velocity stack CAI. length in piping will make a big difference. 4" velocity stack versus a short ram with a conical filter.

here's one of my videos for reference. the torque numbers will be different, but hp difference in increase should be simular.

That's a huge gain. Was that 4" piping? It didn't look as monstrous as in Paul's pics. I'm gonna say he gains 5whp. The comparison with the stack sticking out into the air isn't really ideal. Considering the short ram was probably heat soaked with the under hood temps, the stack was definitely able to get cooler air from outside the hood. While I'm sure there are gains accompanied with the CAI/stack alone, they wouldn't be that drastic with the hood closed on the street.

waiting on the 4" elbow and the velocity stack, i would be happy with 5whp , like i said this is a test i really just hav fun with it but any gain is helpful and i will not be using a filter just panthose lmao
