Thread: Product review: BPi Flow Stack

i figured id try one of these out quite a while back. i did some back to back runs with it on my 212/151 stock ve set up, and it did almost nothing. i believe i gained 2ftlbs at around 6k. that was it lol.

Interesting, I know a flow stack made my car run much better with AC on. Say AC takes 20whp away, it felt like flow stack got back 10whp.

I know that it did in fact give me 5whp on the dyno but that's with a snail

oh well for some it works and for some id doesnt. my runs were back to back, so i can say for sure it did nothing. just putting it out there

Mine were to. I will say the different was about 1-2 whp without a filter, with a filter it was 5whp.

Installed this on Wife's car, will have butt dyno results tomorrow

Looks good. LMK what you think of it.

I've never liked that filter for either a cai or wai. Big flat piece of metal right in front, blocking any direct flow of air. Vadim, I see that you have an air tube running right up to that plate on the filter. I know when I bought my cai, I replaced the filter to one that has no front plate.

I really think this makes a difference.

I agree with you Vladah, but my thing is I bought this one at first. Then I when our friend Dabrits found the pop charger like replacement I bought another one for my car though.

I will dyno test both of the filters, and I'm sure the open end one will do better. It's just I already paid $40 for this K&N one, so might as well put it to use. My car will get the one pictured below though.

I am debating on ordering the BPI flow stack, but I did order my S&B filter.

BPi works, I tested it myself on the dyno.
