I am not going for loud, or quiet necessarily, just curious. How much more aggressive does the turbo sound on GMS1? (or the whole car for that matter? blowoff, exhaust, ect) I am leaving my intake stock, besides the airbox mod. My only mods will probably be GMS1 and a catted downpipe. Explaining "loudness" isn't easy, can be kinda subjective, plus peoples mods vary, but I am sure someone here has some insight.

 

like this loud l----------------l

 

Oh, really? I was hoping for something more like this much |||||||||||||

You put GMS1 LNF on your LSJ? cool...

 

Considering the stage kit doesn't modify the induction system or the exhaust system, my guess is any sound change is minimal. Maybe it sounds different/louder under high boost since the turbo pushes more air, but otherwise it's probably the same.

Should be able to let you know in a week or so

 

You can actually hear the turbo easier and if you add an intake that helps A LOT too

 

normally it goes pssssssss. now it goes psssssSSS when spooling. honestly if that justifies spending $700 to you then so be it

 

its noticibly louder, but its not going to make people turn their heads if they hear it outside...

 

Sweet!

 

It's noticeably louder, mostly because now we're pushing up to 20+ psi! When you're light on the throttle and at ~5-10 psi it sounds the same as before, but when you really lay into it and get the boost up you can hear a distinct difference.

 

Sounds the same in first gear.....

 

have you ever heard the turbines on a plane spin up before take off....

 

On the stock airbox I don't notice any real difference in turbo sound (it might be a little louder, but if so the engine and exhaust drown it out), but the recirc valve is noticibably louder opening at 20 psi vs 15.

 

I can hear a additionnal growling ... like ŤI'll own your assť kind of growl

 

The turbo is so much louder lol 15 PSI versus 22? Yeah it "whines" a little louder

 

Bitch. What do you know about the stage kit? Hahahaha.

 

Bitch I know you will probably never get it Mr. Viper alarm

 

Hahaha. True, true.

 

It rockets to 22-23 sometimes, you can def hear it.

 

I accept with information: The turbo is so much louder lol 15 PSI versus 22.

 

hmm if its stock then its gonna be quiet...but with ic piping and intake then you'll hear it spool and the bov will sound louder...people love my car's sound, then again i have an HKS bov
