Why are Evo8's quiet and 9's loud with walbros?
 

We have four Evos at the house between my roommates and I. hahaha, yeah, we all own Evos. :mitsu: {thumbup}

But one thing we noticed is that the two 8's with walbros were quiet, and the two 9's were loud. Anyone have an explanation for this?

Pics later of the driveway. Our neighbors think it's hilarious that we have the same cars, all different colors.

lol @ 4 roomies with the same cars...u guys had them before on each jumped on the wagon 1 by one?

Who knows why the walbro is louder on the Ix's

I have a IX RS and a walbro and its not that loud i can hear it sometimes but its not loud by any means.

Thats Awesome BTW!!

Used to have an 8 with a Walbro, and it was quiet. Now I have a 9, and I can definitely hear it whining away in the back.

Good question, BTW.

get a louder exhaust then you wont hear it :D

The 9's do have a plastic mat between the metal and the seat cushion.

i think it just depends on ur luck.... my walbro isn't too bad... i cant hear it at all with the seat on.....


The pad and rear seat do a very good job insulating the sound on my car.

Cheers!

^yes thats to make things quiet. they all seem to make the same amount of noise to me.

i can hear mine on my 8
its not that quiet

I agree too. Had a 8 before the 9 and the pump sounds the same to me

after a long trip i hear mine, thats it.

Here's a longshot: maybe they changed the metal around the top of the tank, or maybe they change something with the interior?

All I can think, is that maybe it's a different material?

I can hear my Walboro in my 8. However, only at certain times.

Thanks guys. We're all probably going to be ripping two of the evos apart so we'll take a good look at the insulation and fule tank area.

I just turn the music up. Mine is always loud. :)
