The DW301 is the only pump we have. When you see DW300 it is referring to the DW301.

300 is the series name of our 300+LPH pumps, and the DW301 is the first model/fitment we have available in this series.

 

Walbro, should be fine and I have used them with e85 for just over a year with no issued to date.

so more models are coming?

 

I finally decided on the DW300. I should have it in by next Monday

 

Good deal, 10! Looking forward to seeing your results.

That's the plan.

 

thanks i did not know that!

 

Those are not real world testing results. Buschur didn't even have a DW pump in his hands when he made that post.

 

Not too happy with my DW300 order from MAPerformance Ordered on March 28, Monday morning, so I could have it by April 1, Friday to put it in on Sunday or Monday. Tuesday morning get an email for Verification needed for different address it's being shipped to. Fine no problem. I'm happy to have the added security. Take care of the Verification Tuesday morning. Ask for tracking # on Wednesday get it on Thursday. Picked up by FedEx end of Thursday, still in Saint Paul, MN today, Friday. Scheduled to be delivered on April 5th, which means I won't be able to get it in until my next day off Monday, the 11th of April
Too bad I'm going out of town on the 18th for a week.
Sorry I'm b!tch!ng. Bad week, just got laid off. Just needed to vent.
Now I'll have a lot of time to dial in those injectors and tune on e85

 

Walbro which is already proved itself countless times bud.

 

Sorry for your confusion, I thought I had made it clear that the DW testing results were "factory" testing results - "un-modified DW factory pump testing results." In addition, I did not refer to the results as being "real world" testing results, just "some" results that are available at this time.

In any event it is a reasonable comparison between the modified Walbro 255 pump and the unmodified DW301 pump to make a decision on whether to purchase the DW301 pump or not at this point in time. Worse case, if the DW301 pump does not perform per the "factory" testing results the buyer can return it to the Dealer for a refund.

My guess is that the DW301 pump will perform as DW has tested it and that when modified like the Walbro pump, will out perform the Walbro pump, albeit with no Warranty.

 

I'm very sorry about that delay sir The verification is a one time deal and you shouldn't have to go through that on your next order.

 

Thanks Chris! I'm finding the silver lining in everything lately. The verification process is a great security feature that protects the vendor and customer. I never thought about that. Since I was let go recently at my job, I've decided to start an online business for sports and this would be a great additional security.

BTW, I haven't had a problem with your company and once I find a good one I stick with them
Thanks!

 

Just posted today by one of the shops local to us...

 

Alright, I installed the DW301 last a week ago and have been dialing in my new injectors.

I put an automotive stethoscope up to the metal cover under the back seat with the OEM fuel pump still in and car idling. I could not hear a thing. Then I took off the cover and listened to it with the scope on the plastic. I could barely hear it. After I installed the DW301, it was slightly louder, but I could only hear it with the stethoscope.

Pump is working great! I have plenty of fuel at WOT. I will be upping the boost this weekend. I've been tuning the fuel and timing all this week. I'll update.

Thanks MAPerformance and DW! BTW DW, I love the sticker included with the pump I have it on my laptop that I log and tune with. MAP I need a sticker!

 

Good deal! Thanks for the review.
