Just curious who's running what? How they like it? etc.



I did the home depot BOV on my old FD but I'd like to purchase one this time around. Anyone using a Turbo Smart BOV? If so, how do you like it? Also does it really flow the most air like they "claim"?

AgentSpeed 09-17-2005 07:21 PM

I've got a Tail BOV and I'm happy. I didn't put a lot of effort in searching, Chuck from Rotary Extreme recommended it for my set-up and boost levels. It's worked great for me.

Rob x-7 09-17-2005 07:30 PM

I hope this gets some responses, Im in the market for a BOV myself



I did secure a nice brand new Innovative Turbo Sytems wastegate though for a great deal.

stock works just fine for me...

Rob x-7 09-17-2005 07:46 PM

I never had a turbo on my car let alone a BOV https://www.nopistons.com/forums/pub...closedeyes.gif

I'm looking for one that isn't ricey loud.



I found a webpage years ago that had a graph showing which BOV's flowed better than stock. It was all based on a percentage ratio. I'll see if I can't find it again.



Whos running in the 15lbs range and what BOV are you using?

jspecracer7 09-17-2005 11:10 PM

Greddy type R. Also the Tial is a good unit.

I'm running @ 15psi, I guess I should have said that...

Il RX8 lI 09-18-2005 04:15 PM

I'm looking into Tial as well. Agent, any idea on the sound? I don't want to sound like a ricer driving around, but would like to be reminded it's working.

AgentSpeed 09-19-2005 09:14 PM

It's pretty quiet compared to the rest out on the market that I've heard. Mine is welded onto the outlet of my v mount IC and I can barely hear it when I let off with the windows up and the a/c on.

Il RX8 lI 09-19-2005 11:53 PM

Sounds good to me. Edit: What would be great is if anyone happens to have a sound clip.

AgentSpeed 09-20-2005 04:37 PM

Maybe the next time I'm down towards B-ham, you can hear it. I don't have the ability to record a sound clip. I'm a tard...

Get the stock sti blow off valve or the super sequential bov my friend has a 1000hp supra with it and i love it

pwwatkins 10-17-2005 11:47 PM

does the blow off valve go back into the air intake. if so can you take it off and let it free flow into engine bay, i think that is how mine is. really loud

sweet7 10-18-2005 01:18 AM

Yeah thats the home depot (million other names for it too) mod.

GreyGT-C 10-18-2005 03:27 AM

i have a Tial also... i like it.

just-some-guy 11-09-2005 03:20 AM

if you're looking for one that isn't ricey loud...

stay away from the turbosmart.



i used to have one on my car, it is loud. i used to be able to hear it with the music blasting (guns and roses) after boosting lightly.

bah the RFL makes you go insane after 5 minutes of riding in it.



the type-s is a piece of ****, i know a lot of people who have had problems, can't go wrong with the tial but its a bit quiet. the blitz i've heard leaks a little, the hkssqv is probably one of the most functional but i really dont like the one that sounds either.

rfreeman27 11-15-2005 12:09 AM

I have dual RFL's, they are fine.

I guess the question is, how loud is loud? I dont think I've ever heard one in person before.

AgentSpeed 11-17-2005 07:02 PM

I've got a sound clip of my Tial BOV:
