---- Blocking Blow Off Valve For "Dose" Noise... Worth it ? ----
Not my monkeys, not my circus.... lolz. So recently saw a thread on FB discussing the blocking off of the blow off valve with a plate made from an aluminum can, this was specifically on a RB25DET, but the same principal applies to most turbo vehicles. the aim of this "modification" is to attain the "dose" sound from turbo equipped cars. Whats that you say? you dont know what "dose" is? well here is a handy video to help you out on that front....
Ok so the basic idea is that you block off the blow off valve, this stops the re circulation of the excess pressure that builds up in the inter cooler pipes when the throttle body closes. This creates the "tsu tsu tsu" noise you can hear in the video above with no actual performance modifications being made to the vehicle.
But this kinda speaks to the point here, this noise is usually the result of actually doing performance work to the vehicle. changing parts over which are aftermarket and are designed to improve performance , but importantly are designed to take the kind of abuse and strain that high performance vehicles place on their parts, the byproduct of these upgrades is some funky noises.
This here is a shortcut to that noise that comes at the cost of a can of drink and a bit of time and elbow grease. unfortunately this has resulted in some people blowing turbos, messing with idle, staling, etc.
What we need to keep in mind is that manufacturers have spent millions of dollars in engineering, if we want to redesign the performance aspect of out vehicles , thats fine. However, hacks like this can have some adverse effects when applied to near stock vehicles.
The truth is that its up to you what you choose to do to your vehicle, but we must be aware of what it is that we are doing and the consequences of these actions. It may be cool to hear some "dose" coming from your vehicle, but is it worth it if there is even a risk of it damaging the motor?
Before doing any mods, do your research, evaluate the performance vs reliability, find good sources of data, consult performance mechanics if need be, do the job properly and keep on drifting :)
Keep On Drifting
Hah no I would not block off the BOV, its there for a reason. Now venting to atmosphere is completely different.
Atmo venting a factory bov can cause other problems too, lolz. if the car is built you can do what you want, my AE86 has no BOV. My stag has a HKS SSQV. both built. you can tune for these things, but when its a bog stock car these kindsa hacks tent to have adverse effects
@mfxae86
Its just bad for the enviroment, but so are open exhausts and such. Your AE86 is turbo charged? Thats not stock... hah.
I guess if the car is built for it, just seems counter productive to block off a pressure release value for some cool sounds. But so are whistler tips and other things, just done for the lolz I guess.
BOV is for sparing the factory turbo as they are designed to operate a particular way, "where" that pressure vents becomes an emissions issue, but its not the sole purpose of the BOV. When the whole car is designed to function effectively you can do as you please, look at antilag systems.... then think about doing that to a factory turbo set up, lolz.
Yeah my 86 is fully built to do what it does.... no BOV is just the tip of the iceberg on that car. BUT it is designed to be that way and has not had a problem running like that at all.... besides blowing gearboxes, drive shafts and diffs, lolz.
But it's hectic bruvs!
fully sick cuzi bro, tus tsu tsu tsu !!!!!!!
fully schik ka-lay bro XD
pulls chicks and duz skidz bro !!!!! lolz
but duz it have the shweet shubwoofeah and the innacoolah from blinkah to blinkah?
XD
you know it mang, Errrrybody at the kebab stand loves it !!!!!!!
