i was told by Bryan that a customer did a comparison on a GSR between the Injen Vstack filter VS the BPi setup and it made 2-3 ftlbs across almost the whole operating range.

for the filter?? the main objective of the filter's size here is to, well firstly it has to fit over the stack, but the objective is to restrict the effects of the v-stack the least

go take a look at the homepage and at the pressure and velocity gradients that brian has up there.....theyre all modeled with the filter on, which is pretty cool

yea, the filter is going from a 3" to a 6" and for the intake are to accomodate that, that is why the stack is needed. And I assume you would want a bigger filter to increase the intake air...


Matt, what exactly do you mean restrict the effects of the v-stack?

the radius of the bend on the stack and the inlet size are all factors in how the v-stack pulls air more efficiently than an open tube, beyond that, i dont know enough to explain....

buuuutt.....a bang bang bang on the door and woop there it is:




hopefully the ebay intake gets here soon

so what about the comparison to the apexi intake filter? like stated above isnt it basically the same thing? because if it is you can get the apexi for 101 from inline four.

edit: also what about taking it and going cold air with it think that could yield more results?

i'll get some tomorrow. I hadn't ever really thought about if it would fit if you havent done a battery relocation. You could prolly get it to fit if you cut the intake the right angle but im really not sure. The filter is HUGE. I'll look at it tomorrow when i take pictures and give you my opinion.

it could be similar, but definitely not the same. thats something i think bryan should have the right to explain. And about the cold air. I guess it could work, but i dont see the filter fitting in the tiny area that the filter sits on a cold air. I dont think you guys understand how big this filter is, lol.

having the stack on the end of the intake pipe, before the filter is why this thing is worth doing....

the apexi has some sort of funelly-something, but its on the far end of the filter.....its worth a few pulls on the dyno to see if theres any results to be had, but i feel that i have made a good purchase as is

yeah i see what your saying. im not in any way trying to down this product just trying to understand the apexi product lol, but it says the apexi has 2 funnels 1 at the tip(secondary) and then one at the base(primary which i believe to be a stack) and looking at the air flow pics posted on BPi's site it shows somewhat the same as this pic showing the apexi air flow.

again im just trying to understand if they function the same b/c ive heard good things about the apexi and if there the same then same will apply to the BPi stack.

apexi is on the left in the pic. you can see how it has the same "curved" base as the BPi stack.

well its the same idea, now its just up to determine whether the BPi or the apexi has the better design....

someone send me one and i will test it on October 21st when i dyno.

being able to run just the flowstack without the filter is kinda nifty too.
