Well I am going to be buying an upgraded fp for my e85 setup. Question is how bad do the walbro 255's whine? Is it that bad that some people make it out to be? If so are there any other comparable pumps that are quieter?

The 255 will run out of fuel for e85 soon. Id advise the new dw300 or the new walbro 490 lph. The walbro needs your pump housing to be cut a little bit to fit. Both are quiet. You would need to rewire both pumps for higher hp above 500 or so

The 255 does whine. I recently removed my back seats for the AutoX season and the whine is even worse now without all the padding to dampen the sound.

M8, I'm not running E85, but I've had a walbro in my Evo V and it whined loudly. Granted, everything was stripped from that car from the front seats back, but you could easily and clearly hear it going. Over the exhaust, over the casual radio, over conversation.

When I got my IX, I was much more focused on having a 100% usable street car, and as such, I knew I wasn't going to go Walbro for that reason.

I ended up grabbing the DW301 (which they tout is E85 compatible, though I can't confirm nor deny that). But it sounds 100% stock inside the car. From the outside, you can hear a SLIGHT whine. But inside, nothing.

Haven't looked back.

Get you a turbine stype pump like the new Walbro 400.

I'm running e85 on my walbro 255 and it sounds the same as when I was on 93. Only whines sometimes but like others mentioned above it isnt very noticeable with the radio on or windows down.

A 255 fuel pump can handle about 500whp before it being maxxed out. I personally don't hear mine ever.. Maybe if u have an RS Evo u will bec u have no sound damping in that car

i personally prefer the walboros whine, ESP over my gf's.
but yeah with the back seats on it dampens the sound, but my car doesnt have rear seats so i hear it all day but actually do enjoy it for some reason. And yes when i gets "hot" after pushing the car it'll get substantially louder
