I have seen some people running velocity stacks on turbo cars and was just wondering if there would be noticeable benefit to this over a filter? I haven't seen a small enough filter to fit on a stack and sit in my engine bay either.

Thanks!

 

Obviously you want a filter on it if it's a street car. It's not worth it to ruin an expensive turbo/engine to pick up 10hp.

 

^^^What he said. You'd be amazed what a few tiny grains of sand can do to a turbo impeller. Don't chance it.

 

yea, what those guys said lol

 

i guess I asked the wrong question.

Does anyone know if a filter like this exists just shorter? I would like to run a flow stack unless it really isn't worth the time and money. Would it hurt to just change the filter to the velocity stack at the track then perhaps? Just wondering if there are any significant gains from this? I always run filter on turbo setups.

 

is this a serious question?

filter at all times

 

Blox makes a filter for the velocity stack theres even a k&n part number floating around. However I don't honestly think it will help that much for 60 bucks

 

I'd just run a normal filter on the turbo if its a street car man, trust me... not worth the minimal horsepower by running it without a filter. the 1 time i decided to run mine without a filter to race my friends z06, something got sucked into and completely ruined a $600+ garrett t3/t4... plus the velocity stack/air filter combo kind of sounds like too much of a hassle to run for minimal benefits. just slap a good filter on it and call it a day

 

On the dyno with a car i tuned we saw no gains going from filter to no filter on same boost levels. Honestly even if it was a few whp you wont feel a few whp and your going to ruin you turbo and engine without one

 

but it looks so jdm tyte yo... makes it look hardcore

*rolls eyes*

 

This is what I wanted to know. On my N/A setup the flow stack made 10hp more than my regular filter on a 3" cold air. I was simply applying what I had learned from that experience to see if there is a filter with a 6" opening that was short enough to fit between my frame rail and turbo. But since there really isn't that much of a difference on a car like mine I will just run the setup I have now which is filtered.

Thanks for the info!

 

That means it was one helluva good filter like an AEM dry flow or something to that effect that you had. The HKS foam filters (not the ebay knock-offs) would kill a much as 30whp on some applications I've seen.

 

and then fall apart and nuke a turbo

 

Mac, it was an autozone paper oiled filter. we made first pull with filter on 18 psi made 406whp. with filter off made same power the next pull, intake temps were 4 degrees higher the second pull from heat soak but i dont think that would make a huge difference

 

oh, yeah, the really thin paper oil filters, that basically don't "filter" anything.

 

seems to work just fine, ive run them on my car and hes been running it for quit some time. both on our third filters without and turbo or engine damage. They get dirty pretty quickly but other than that they filter

 

I need to find that part number for the short version of that filter.
