Not from me. I decided to buy the Walbro 400 and an aftermarket adjustable FPR. I have not installed them yet.

To the OP how much a difference was there between the DW and the Walbro? Im on the DW now and Im running out of fuel with E85. I did the rewire also but still not enough flow. Im thinking of going with this pump but Im not sure if Im wasting my time and money.

 

dont mean to hijack but im stuck btw the 400lph and dual inline pumps. I have maxed out my rc1000cc and walbro 255 on e85 and I am stuck btw going for an inline or trying out the 400lph.

 

Sounds to me like you need bigger injectors and pump. I would get the 400pump 1st as this will help push your 1000 some more.In the end your most likely going to need bigger injectors. Even with throwing as much fuel at the injectors as you can.

 

Sounds like it's time for bigger injectors, Walbro 400 & probably an adjustable FPR. Or you could go with a double pumper and a Hobbs switch in which case you won't need the adjustable FPR.

 

i see on ebay there are kit for this pump. will the kit let me avoid having to cut into the plastic housing.....I currently have a 255 and am about to switch to e85 in about a week.

 

You need to cut the housing no matter what. Unless someone comes out with an aftermarket housing to just drop in.

 

just cut the housing, its not that big of a deal. plan it out and do it clean

 

David from Buschur suggested the same thing and I think I will go that route. But when you say I'll be able to push the injectors a bit more, how much more considering they were at 95% duty cycle at 6k with the pump maxed out. My tuner also suggested Aeromotive.

 

I would say it will maybe bring it down to 80-85%. You can try the aeromotive but you will most likely still run out of fuel.

 

so any updates on the stock fpr and this pump?

 

im pretty sure once you rewire its gonna overrun the stock fpr. my customers installing this pump tomorrow in his evo 9 not rewired so will get some data with it not rewired and see how much power it can support on e85 with fic 1550's. he only needs around 550 since hes still on stock block.

 

I'm interested in the results of this. Any updates?

 

X2 since I might go this route too. Thanks to the OP for the good info.

 

if nobody answers this question in the next 2 weeks, ill be running stock fuel rail & fpr on my personal evo project build, walbro 400lph and id 2000cc injectors
