i just bought a 93 rx7 touring and i need to know if the pipes running from the stock intercooler are plastic or metal, bc the bov may need to be welded on. im asking this bc i have not yet actually seen under the hood yet. will someone please let me know?

I hope you realize the aftermarket BOV isn't a performance mod. It's basically a noisemaker.

Do you have a manual or an automatic transmission?

You just bought an FD WITHOUT seeing under the hood, and the first thing you have planned to do is weld in a BOV? I think you have a rude awakening coming. Good luck.

Im curious as to how you bought it. Please dont say e-bay, my friend just got raped in the *** from them. Car looked great in the photos, but no pics of the interior or engine bay. Turns out the pics were 2 years old, and the car didnt idle, had a cracked windshield, no center console, wires hanging out every which way, no screws to hold the intercooler on, missing screws on the alternator etc...

I second Rynberg, good luck.

TRANSLATION: "Is the BOV that cool thing that makes the 'pish' sound?? All these mad tricked out civics around town have them. If I had one, not only would they consider letting me drive with them, I might finally get the attention of that girl in my high school who doesn't know I exist."

Fast vs. Furious:
Enthusiasts from different backgrounds have differing opinions of blowoff valves


Pressure Relief
The Charge Relief Valve (commonly referred to as the Blowoff Valve) is a key component in any turbocharged vehicle. It vents excess pressure when the throttle is closed in order to prevent compressor surge and help prolong the life of the turbocharger(s). The factory Charge Relief Valve is plumbed back into the airbox, to maintain a quiet and consistent engine tone. In cars with extensive modifications, the factory Charge Relief Valve may not be able to cope with the increased pressure that is produced by aftermarket turbochargers in the constant pursuit of ungodly amounts of horsepower. For these vehicles, and aftermarket Blowoff Valve is necessary to avoid damaging the turbocharger.




Hot Air
Aftermarket BOVs vent their pressure to the atmosphere, yielding a loud 'whoosh' or 'pssssshhhh' sound as the pressurized air is released. Many people find this sound pleasing or 'cool.' Young enthusiasts often associate the blowoff valve sound with fast cars, because most high-power turbocharged racecars are equipped with loud BOVs.





Imitation, Flattery, and Loud Cars
Many younger enthusiasts cannot yet afford to modify their cars as extensively, or choose not to due to reliability concerns. Wanting to sound as cool as the racecars they see on TV or at the drag strip, they often purchase aftermarket blowoff valves to make their car sound cool also. It is not uncommon to see an otherwise stock VW Jetta 1.8T with an aftermarket blowoff valve, revving their motor at a stoplight to make the 'whoosh' sound in an attempt to impress their fellow students. What many of these kids do not know is that an improperly tuned BOV will decrease engine power by venting too much pressure each time it makes the 'whoosh' sound.




Conclusion
Are aftermarket BOV's a threat? Should young enthusiasts be chastised for wasting their money? How much boost can the factory CRV tolerate before it becomes a liability? Does a twin-turbocharged motor require two blowoff valves? All of these questions can be answered in many ways, and the responses will differ depending on who you ask. There are two common viewpoints with regards to blowoff valves:

BOV's from a racer's point of view:
"Is is lighter than stock? Will it make more power? Will it make me a target for law enforcement harassment?"

BOV's from a ricer's point of view:
"Is it shiny? Does it sound 'cool' like Gran Turismo? Do all the JDM touge drifters have one?"




It is not the intent of this article to make any recommendations for or against blowoff valves, only to educate the uneducated with regards to the history and common uses of Blowoff Valves as they relate to turbocharged vehicles. Street racing is stupid and illegal. So is breaking the speed limit, removing smog control devices, and running red lights. All rights reserved. Please use your turn signals and be a safe driver.

Everyone knows what a BOV does and why it's there. Yes, for a heavily modified car, a BOV might actually be a worthwhile purchase if the stock CRV can't handle the extra boost; I have one for my 60-1. No problems here.

In reference to this particular instance though, the guy is running the stock intercooler. Which tells me that either a.) the car is lightly to unmodified in its intake system, perhaps replacing the stock airbox at most, or b.) if in fact the guy IS running single and is pushing the boost necessary to consider upgrading the CRV, he's got WAY bigger problems than worrying about how he's going to superglue his aftermarket BOV to his stock intercooler pipes.

Either way, the initial question was idiotic and was met with appropriately idiotic responses (i.e. your "racer" point of view)...

If you think that's crazy, a guy called me about buying my car and said as quoted " can you fit two blow off valves in it, cause it's a twin turbo yea?"

I'm serious, this is no joke although i felt sick when I heard that.
