Lots of guys here in the midwest all run e85. A local owner of an 04 WRX runs e85 on stock td04 turbo. Put down 285hp/301tq on a superflow dyno. Granted its a stock turbo and it makes peak power and falls off drastically. You need MOAR turbo for sure.

I gained right around 20whp and 40ft/lb when I switched to E85 from my 91 octane tune. I gained the same amount on a conservative (actually conservative, only hit 21psi) with my small 16g (35lb/min). Then I switched to E85 with the 16g and made significantly more power than the td04 with E85.

My DW300 put out the same flow as my walbro 255 did. Both direct wired. Don't waste money on the DW300.

E85 is great, as long as you keep track of the different grades of E85 through out (can be up to 4, depending on how cold it gets in your area) the year and check your tune to make sure it's still good. It also sucks to travel with.

Basically, I wish I would have went straight to a larger turbo right away instead of wasting money on E85 with the tiny Td04. A used VF turbo will put out the same if not more power with less hassle and no worry about traveling or tuning issues. Just get a bigger turbo.

Get a second map for pump gas and e85 no longer is a hassle to travel with.

My Walbro was giving me trouble starting and I was only running e85 for about a year. The DW300 sounds soooo much better when priming. Like a jet plane. It starts up instantly as well.

I wouldn't risk it with the 255. I know a lot of people run e85 with them but I want a pump guaranteed to work with the E.

How did you come to this conclusion? Were both pumps flow tested?

Both pumps were maxed out at the same power level on the dyno (400whp uncorrected) on E85. Super low reading dyno. Apparently they had this issue with other DW300s as well.

Fuel pumps aren't always the limiting factor. There could be some restriction outside of the pump limiting the amount of fuel getting to the injectors and ultimately the cylinders.

Our pumps have been tested by us and non-partisan companies since they were released 3 years ago. If what is claimed was true, it would have been discovered rather quickly.

I agree, they aren't always the limiting factor, but they were on my setup. Nor was I the only car that they had issues with. I'm sure the DW300 pumps more in the laboratory, and in theory it should put out more power, but it did not in my real world use of it. There could be numerous reasons for this, it was an early production one, it could simply be that the extra 45lph wasn't noticeable in a real world application, or who knows what else. Nor am I the only one that had issues with this. Nor was it the only turner that had issues with this. Whatever the case may be, it doesn't particularly matter, I'd still recommend a 255, double 255, or a 400.
