Blow off valve help
I currently have the APS dual vent bov on my car but i want to sell it and replace it with a louder one. I know that 100% atmospheric bov's can cause problems, but i was wondering what was the loudest bov you have found that does not cause any problems. Any help would be appreciated. Thanks in advance.

i've got an rfl
if you have leakage or idle problems, then you need to increase the spring pressure in the bov.
that's not just applicable to txs units, or the rfl, but to ALL bovs.
as for myself, i prefer to have a "tight" bov rather than a "loose" one that's constantly venting. as a result i have 4 spacers and a quarter in my rfl, and it works a charm.

I have the GFB Hybrid 50/50 that can be set to 100%. I love mine but if you wanna go loud all the time then go for a Turbo XS my friend has one and he digs it. Good Luck

The txs one is good if you want a loud one. The HKS one isn't too quiet itself, either. The HKS one has different fittings you can get to change the sound also. I think there are three fittings you can get or so. The one it comes with has a high pitch sound to it and is pretty loud. There is another one this is more of a circle shape that loses the high pitch sound for a sound that is best described as a big rush of air. It is quieter, though. I haven't heard the other one, though. I would like to, so I can hear the difference. The fittings are super easy to change. You shouldn't have any problems either putting one on your stock car. It won't help any either, however. The hybrids are cool for stock or slightly modded cars.

Atmospheric venting is atmospheric venting, it doesn't matter which BOV you have. That just changes the sound you get from it. It's the loss of pressurized air that the MAF has accounted for, not the design of the valve. However, it's not something that's destructive to your engine (except maybe your cats after a while). If you like the sound go ahead and use a vented BOV.
