2 Fast 2 Furious Question

I know I'm probably sounding pretty stupid but I have two questions. First, what gives the car that sound like air being released in between shifts? Second I want a muffler/exhaust that sounds like the ones in 2 Fast 2 Furious/ The fast the Furious movies (preferably the nissan skyline gt-4 R34). If anyone can give me an answer that would be great. thanks

I'll try and help you out a little here. The sound between shifts is suppose to be a blow off valve. I'm prolly a little off on exactly what it does, someone please correct me if I'm wrong but from my understanding it's a valve that when the accelerator is lifted up quickly releases gas from the intercooler side of the intake and that air is either sent to the atmosphere or back into the intake.

As far as the exhaust sounds from my experience each engine has it's one exhaust note with each muffler, so getting your Golf to sound like an R34 might be kind of tough.

the blowoff valves releases air that is being built up so it doesnt build up in between shifts

Since the turbo is spinning still and pumping PSI against the throttle body even when the engine is shifting, the pressure needs to be released because the engine is not taking in all that air. Not having a blow off valve would build up huge amounts of pressure which could blow something up. The turbo doesn't know when your engine shifts, so it keeps pumping air - the BOV is there to release the unneeded air that your engine doesn't need when it's shifting.

if you dont wanna spend the big money for a turbo put you still want the sound try this

i must warn you...you will get laugh at if you install it and pull up at a light and rev up and use it

LMFAO!! OMG - That's great :) what'll they think of next! lol

its sad that someone WILL actually pay 150 bucks for that.....<shakes head> lol

if u want ur car to sound liek a skyline ur gunna need a rb series engine like a rb25 or rb 26

They should make a movie "Ricers gone wild"

idnyram...lol...i would buy it too. Would provide countless hours of laughter along with boosting my self esteem in knowing that i will never be that stupid

well,the boost valve thing has been explained nicely...

As for the exhaust note....tear out the rear seat of your car, fit a film studio sound mixing desk ,two really large speakers, and a microphone close to the exhaust tip.

Mix until you get the exact note that you think is macho enough, then set to simoultaneous playback and go cruising.

And I've heard that a blowoff valve gives you 35.4% more boost if you duct tape a duck call to the outlet........

LOL - or if that doesn't work, you can parralel wire your flux capacitor and you'll be looking at similar gains!

pift, if your lookin for horsepower....get the duck head decals for your back window...HUUUUGE gains

The sounds in between the shifts is the blow-off valves. The exhaust is tricky. Try Greddy's or HKS.

LOL - I considered removing my mod stickers from my back window for a weight reduction :)

They did It's called The Fast and the Furious. I think they made a over budgeted sequel too.

^^hahahah...that BOV noise that you can buy for 150 bucks is a rip off. I rather yell "VRRROOOOOOOM..PSSSSSSSSSHHHTTT"

that would be so funny to hear. it hardy even sounds like a BOV anyway.

I thought that the stickers gave you like 50 extra hp or something. LOL!

no no no yellow sticker add 50 extra hp! LOL
hum? 150 for a fake bov or just over that for a used real turbo and the intalation, hum what would i pick? (*note* prices for turbo are a guesstamation)

turbo is more expensive then that, but yeah anyone who has that ..... :screwy:

you can get a turbo for 150.....but to actually make it work its gonna take a little more.

whats with the duck heads on trucks though??? i see them all over the place and i have no idea why the hell people have them.

I gotta say, when the purpose of the BOV was explained one part was left out. That is that the BOV is also an insurance feature for your turbo, because if there is no BOV when you lift of the gas a sort of ...uh...shockwave... type... thing can get sent back down the piping and shatter the turbo compressor wheel. So the BOV releases the pressure that causes the shockwave...or somethink like that, I'm not 100% on how it all works.

Also that thing to make your car sound like there is a BOV is really tardy, if I ever saw somebody that had one I would laugh, and laugh, and keep laughing, etc. until they felt so stupid that they killed themselves...ok maybe not that much laughing. But you get my point.
