Guest Jeffn Posted November 6, 2006 Share Posted November 6, 2006 How big a deal is a BOV? I've seen guys on other make turbo sites claim they were a waste of time/$$. Your smec for my T2 works wonders after about 60-100'-maybe bigger exhaust? Link to comment Share on other sites More sharing options...
89TC-16V Posted November 6, 2006 Share Posted November 6, 2006 Leaking BOV can be totally robbing you of boost and does make a decent amount of difference. not hard to install and then you get a nice sound or you could vent it back in and be quiet. Never a waste of time when it comes to upgrading since the factory ones are cheesy and barely good for the stock amount of boost Link to comment Share on other sites More sharing options...

Guest mtworkshop Posted November 7, 2006 Share Posted November 7, 2006 OK, so what is a "BOV?" Where is it located? How do I know that it is working? <img src="http://forums.aaca.org/images/graemlins/confused.gif" alt="" /> Link to comment Share on other sites More sharing options...
16vGLHS Posted November 7, 2006 Author Share Posted November 7, 2006 BOV = <span style="font-weight: bold">Blow off valve</span> and it's located inside your airbox (the worst possible place they could have put it). Not only does it tend to lift off its seat around 6-9psi but they put it right in the path of incoming air to the turbo (thereby acting as a restriction in the stream of incoming fresh air to the turbo's compressor) and also disrupting the otherwise smooth laminar airflow. But I'm going off on a tangent here, sorry.In layman's terms: A BOV is a valve that diverts air away from the turbo's impeller during throttle "lift" conditions just following a "boost" condition. The BOV's job more or less is to keep the "leftover" boosted air - in the intercooler piping - from backing up on the compressor wheel upon throttle lift. This is done in an attempt to keep the thrust bearing inside the turbo from deteriorating over time. BOV's are good. Leaking BOV's are bad. Leaking BOV's also cause the turbo's compressor wheel to "overspin" while in boost, which in turn superheats the boosted air and results in an even greater loss of power. (due to a resultant higher air charge in the intake)Why does the turbo's compressor "overspin"? It overspins because it's trying to maintain a certain boost pressure in the intake manifold's plenum but the leaking BOV is not staying shut and some of that air is thus LEAKING out to atmosphere (while in boost) which in turn causes the turbo to push harder and harder thereby superheating that boosted air which raises intake temps which kills power. As we all know, denser air = more air molecules available for combustion = promotes a better explosion = more horsepower.Suffice to say, if your BOV is leaking you are losing power. In order to quantify how much power you're losing you'd have to know just how badly your BOV is leaking. Most TC's I've seen have either completely blown internal diaphragms or ones that leak at a certain boost level (typicall 6-9psi). So....if you want to run a Stage II computer it's a good idea to get one of my BOV upgrades to go with it. In some *rare* cases the stock BOV will not lift off its seat until around 12psi or so, but as I say that's very rare. Most of them are total garbage for anything more than about 6psi or so. But don't take my word for it, ask others who've been working on these engines as long as I have and they'll tell you the same thing. <span style="font-weight: bold">The factory BOV is often your HP limiter!</span> The BOV upgrade I offer is a direct bolt-in unit and comes with complete installation instructions, etc.. It's a relatively easy item to install and anyone with even a small amount of technical ability can do it.Cheers,Rick D.www.rdiperformance.comSpecializing in performance upgrades for the TC Link to comment Share on other sites More sharing options...
TwinCamFan Posted November 7, 2006 Share Posted November 7, 2006 Years ago, the day I got my TC home, I fixed the exploded PVC valve. The very next thing I replaced was the stock, inadequate BOV. It drove like a different car after that...I have purchased many upgraded or performance TC parts from RDI performance over the years, service is great, and the items arrive on time (or sooner) and packed meticulously. Top notch service <img src="http://forums.aaca.org/images/graemlins/cool.gif" alt="" />Alan Link to comment Share on other sites More sharing options...
DonziClassic Posted November 7, 2006 Share Posted November 7, 2006 We are new to the TC's but had Rick at RDI Performance put the larger throttle body on our newly aquired '91 model v-6. It was having a problem with stalling out when braking or turning. The difference in pep and performance was drastic. It is as smooth as glass now. Wonderful upgrade.Now I can't wait to see what it will accomplish on a 16v. Great Job Rick! Tom Link to comment Share on other sites More sharing options...
