what is better for mazdaspeed3, recirc..or vta blow off valve

depends what you consider "better".VTA will give you more of the traditional BOV sound, but you'll run rich between shifts, possibly backfire etc.
Re-circ is how the car was meant to run. You won't hear as much "psshhh" sound but the car will be happier running that way. In the long run I think you'll be better off running it re-circulated.

Any questions? Actually it's an MS6, but you get the idea. I have read that you can avoid this by relocating the MAF, but otherwise you're going to lose substantial power going VTA.

Damn that's rich. I think the VTA is out of the question. Thanks for the post.

Strange they work for me. Anyway it's before and after Mustang dynoes showing a 25 hp drop due to VTA.

STi has this same problem but, its even worse. Guy did a before and after and it was near a 40 awhp drop to VTA.

is the hks super sequential blow off valve vta or recirc?

 

[Vermilion]

Its VTA normally but, they make kits to make it a recirc. I believe Crossover Auto sells both the Greddy VTA and Recirc and the HKS SSQV VTA and Recirc kits.

Yeah it should still make some sound. Adding a coned CAI or Short Ram intake will also make a "blow off" sound even with the stock one.
