Last month I put on a TBE, intake, mbc, IC pipes, custom tune, and a walbro fp. Pretty much from day one I've been hearing a loud whining type sound from the back seat area. I've been told that it's the walbro making all the noise.....is it a common thing for walbro's being loud? Should I be worried about this?

Thanks

 

fuel pump!

 

Should I be worried or is this normal for fuel pumps?

 

its normal for the walbro. that is why it is called the "whinebro"

 

Definately your Walbro.

 

whinebro

 

lol, luckily i new it was gonna whine befor i put mine in... its normal

 

yeah walbros do that, but only until you get some open exhaust- then you wont hear a thing :-)

 

OP-not hijack your thread, but just interested in what kind of numbers you're seeing with those mods? I'm looking to do almost identical...

thanks

 

 

I can still hear the walbro and I have a full 3'' catless TBE with a HKS carbon-ti.

 

I put down 306whp / 329wtq on RRE's dyno which I hear reads pretty low. Boost is set @ 22.8 psi on pump CA 91 fuel. I see full boost right @ 3k RPM

 

youre still going to hear it. 3in exhaust isnt going to make it disappear

 

OK
So basically I just have to live with it right? Well as long as it's not an issue and only noise then I'm cool with it.

Thanks everyone for the help!

 

Just to add to this thread even though it's about 10 days old. It's definitely not an issue however, I've been reading some other companies such as Denso and they have a fuel pump that flows 255LHP but "better and not as loud." So they say, just look around...
