Turbo XS BOV? What are your thoughts.
I had one on my car for a while and I liked the noise it made and all. But I did not like the lag that it gave me inbetween shifts. It seemed like I had to really make sure I gave it a good amount of gas before I let the clutch back out. Also the car runs rich, so much so that you can see the tail pipes getting dirty from the unburned fuel.
My question: Does this only occur with the Turbo XS BOV or will this happen with any 100% Atmospheric BOV? Is there another BOV out there that is better?

Perhaps others who use the TurboXS BOV can comment here but I thought the purpose of any BOV was to help alleviate turbo lag in the first place.
The issue of the tail pipes getting dirty seems to be something common with any WRX, regardless of which BOV you have installed. I wash my car each weekend so the build up isn't quite so bad. It happens all the same though. David |

I'm sure all atmospheric BOV's will result in the same since they all do the exact same thing. I took mine off too the other day when I had to take the car to the dealer to get the EGT probe replace and I had it on since 1,000 miles on the car (the car now has 15,000) and I never put it back on. I'm getting 20-40 miles more to a tank and the car is alot smoother in driveability. I must say I love the sound of a BOV, but that's it. The car changes gears smoother and the accerlation is smoother, no hesitiation except for the lag caused by the turbo. I'm actually trying to sell mine now. That's just my $0.02

I have an turboxs RFL and i love the sound, and the driveablity seems the same, and i have no problems with the BOV at all so far..My STI muffler would turn black around the bottom within a day of me washing my car before the BOV so i think thats normal..The BOV doesn't make the car run that rich.. at least enough to effect performance in my car. I think the quality of the TurboXS is very good, and the flange bolted up perfectly and there is no need to remove the IC or anything like that- took me 15min. to install last week. Also adjustable- for reference i'm using 3 washers in my Type-h-RFL
IMO the RFL is the best BOV for the WRX(thats why i chose it) Another good one is the HKS supersequential i think its called, makes two different sound for low and high boost levels, there pretty sweet Last edited by PaulRex; 01-29-2002 at 01:42 AM. |

WOW 3 washers. I do not even use one washer. It does not open up at idle with no washers on. But maybe I should put one washer on and see what that does for me. Maybe it is dumping to much to early and that is why my lag is so much worse. I don't know???
As for the HKS supersequential where can you purchase that and how much does it cost? |

I to have the RFL, I love the sound! So far I have noticed no difference as far as crappy performance bad gas milage (my foots always shoved into the injectors anyways). I have had a rich smell before but thats only when Im sitting in Traffic and I Rev hard just to make a nice BOV tone for the car next to me...
I love mine! ~~Garrett |

Jasno999 what BOV did you have? Does anyone have a sound file of the RFL? I was planing on upgrading the turbo soon so I thought I would first get a BOV. I was leaning twards the RFL untill I heard that it might be throwing off CEL's and is a bit annoying. I have a 4EAT so I'm not sure if it would really seem that loud seeing as tho you can not really hear the stock at all unless you really tromp on it. Now I am thinking I will get the H-type.

I HAVE THE TURBO XS BOV.
It came with the adapter for the WRX. Works well sounds great. Loud enough to hear it, but if you roll up the windows and have the radio on even low you will not hear it. Outside the car it is louder. But you get lag between shifts and run richer. SHOULD I PUT A WASHER OR TWO ON THE BOV? WILL THAT HELP FOR GETTING LESS LAG AT EVERY SHIFT? Just means that you dump later right? |

I've got a TurboXS RFL and I'm using no washers. I don't have any problems at all, but I was looking for this same information and I found this post from TurboXS:

Ok that is great. But I still don't know ecactly what is going to happen if I put anothr washer or two on mine. I see that it means it will take a greater pressure difference to make the BOV release. But the questions is: Is that a good thing? Will that help with the running rich and the lag you get when you shift gears?

Just try it out, i just took 2 washers out of mine so now i have only one in my turboxs RFL and i really like that it would blow off at lower boost levels when driving around, which should help lag but does not seem to be any better than stock.. i think the real benefits of the BOV are at WOT when i'm racing- HOWEVER.. one negative was that when i was following an S2000 today on the highway having fun(not racing) i was in 4th gear and because i have an MBC my boost was going pretty high around 16.5psi at WOT(normal) but i noticed when i would back off the throttle from WOT without letting fully off the gas my BOV stayed open until i let off the throttle!! VERY BAD!! I'm sure this is because i only have the ONE washer in now(before i had three) So anyway it never does this with normal driving or anyother time.. only at high rpms in 4th or 5th gear when i go to part throttle from WOT- Anyway that wouldn't happen if i didn't have a boost controller because it still gives me alot of boost in 4th gear even at half throttle. I'll probably put in another washer to make it (2)in my RFL, but i don't have to really because i almost never race on the highway and it only happens in that situation previously stated and i shouldn't be at half throttle with all that boost anyway so i'm going to try to not be in that situation anyway. Either way i think another washer should help also.

Paul,
I've noticed that as well. When I'm at WOT and I ease up off the gas...it can tend to stay open at certain points until I either get back on it or let up completely. Let me know how more washers affects your performance with regards to that |

First of all what yo usaid bro makes no sense to me. If you add say three washers then it will take more of a pressure difference for the BOV to open up. SO by adding washers your BOV should actually stay closed at low boost shifts and what not. If you take washers away then it will take less of a pressure drop for the BOV to open up and therefore at low boost and high bost you get the BOV to dump.
AM I WRONG HERE??? |

That sounds right to me Jasno, thats what i experienced and stated in last post. In reference to your question about more washers helping a rich condition it would only help at low pressures or rpm's were the BOV does not vent i assume but is not a feasable solutiuon to the problem because any %100 Vent BOV should technically richen the mixture(at least at each shift change it should only stay rich for a moment until the fuel is burnt). But i haven't noticed any performace decrease have you?
Star*Child i'll post the day after tomorow(when it stops raining here so i can test safely) when i put another washer in.. If it doesn't help you can always Shoot it with your bop gun! hehe your name is in reference to Parliement Funkadelect(George Clinton) right? Last edited by PaulRex; 01-30-2002 at 11:59 PM. |
