So ive noticed our Evos dont really make the "turbo" sound while under boost. I was the owner of a 2003 honda Civic with a TSI Turbo kit. It had a T25bb Turbo (just fairly a little bit bigger then the 18G) and when the civics turbo was spooling, you could hear it from a mile away. basicly a WOOSSHHHHHHHHHHHHHHHHHHHHHHH while i was under boost. what is the reason that the Evo's turbo does not make that sound and what can i do to make that sound from the turbos?

I read though this and seems like such a Noob question.. i feel embarased.

 

I can hear my turbo loud and clear. Are you talking about the lack of vta blow off sound? If so that's because the evo uses a recirc system and doesn't vent to the atmosphere.

 

It's the intake, get a cone filter type intake and it will make lots of turbo noise.

 

u'll hear ur turbo literally scream with an hks rs

 

Like they said, get an aftermarket intake. The stock intake box muffles everything except for the "whistle" sound. It gets pretty loud with an open filter, and even better with a hard intake pipe.

 

Isn't that why everyone buys the Evo - for the cool "whooosh, psss" sound? Now I just add my neon kit and I'm set.


Just kidding. Add an open air intake and you'll be pleased.

 

Maybe he is referring to more of the big rig, semi truck turbo sound. Sure with an open air filter you get a whoosh sound, but you dont really get that kinda metalic spinning sound.

 

+1

 

man wait till warrtalon gets a hold of this thread

 

I was actually thinking the same freaken thing.

 

Yep another noob will go down in flames because he actually enjoys hearing a spooling turbo.

 

Nothing wrong with enjoying the spool sound, but actually asking why you don't hear it is pretty lame. I mean, if the car wasn't making power or making strange noises, then yeah, but comparing to a Civic? Blasphemous. The Evo is a supercar that makes tons of power. Why would anyone be worried about hearing it spool up or not? Anyway, it's quiet because of the stock airbox that is very, very good and does not need to be replaced with a $250 just for sound.

 

why would u spend money on something that makes u run like crap?

 

Yeah and u will also hear your car die and stall as well.

 

How's the air up there on your soapbox? Crisp?
