How much compared to the walbro 255lph

0Deatschwerks

I'd like to keep this tech related, so please keep the questions in that realm. Thanks.

Well can you pm me or show me a thread that shows a price then. It's obviously been designed to compete with the walbro. Walbro is $100 shipped with install kit and been proven over and over again. How much hp has been produced on this pump? What was the fuel pressure at?

boostedcivicsir

you can discuss prices in pm.

0Deatschwerks

Ah, now the questions come.

This pump has put down 620awd hp on E85 in a 4G63 DSM. Base psi - 52, Boost PSI 35. Using our 1500cc injectors for the 4G63.

It is very quiet compared to the 255LPH due to the turbine impeller design vs. the Walbro G-Rotor.

After the first of the year, we will have over 4,000 hours of testing complete on a battery of pumps running E100.

what is the pump maxed hp at and how does it compares to walbro and do you have a flow chart you can post

0Deatschwerks

The max hp of the pump is going to depend on many variables.

The amount of power it will be able to support at 3 bar psi is going to be different than what it will be able to support at 6 bar.

In the case of the Mitsubishi posted above, it was able to support about 620awhp on E85 @ ~6bar fuel pressure.

Here is a graph of what the pump flows in similar conditions vs. a regular 255 and a 255HP.

do you think this works best with e85 or pump. and whats your take when using it with c16

C 16 is petroleum based Just like pump..... Its ethanol and alcohol youd need to worry about, theyll corrode not petroleum based fuels

area522010

true didnt even think of that

Where can I buy?

0Deatschwerks

They will be available through our dealer network after the first of the year.

MAPerformance is a dealer of our products, as well as, a sponsor of Honda-Tech. You should check them out.

Maperformance is local to me and get nothing but thumbs up!

Can't wait to get one and try it out.

In for this as soon as its available!!

The flow graph doesn't state what the test voltage was?

I'd like to know if this DW300 pump responds well to higher voltages (16+ vdc).

I run my Walbro up to 18v, and it had no problems supporting almost 700 WHP on E10 (Sunoco 94). It would be a nice upgrade for my car for sure.

0Deatschwerks

Test voltage was 13.5v for all pumps on the graph.

I'll see what I can find out for you on the higher voltages question.

v.i.gsr

Size compared to walbro..Can you run two pumps on a dual pump hanger in-tank with no problems like the walbros..

0Deatschwerks

Dimensionally, the DW300 is similar to the GSS342. If you can hang a 342 on there, you can hang the DW300 on there, too.

speeddave

so what would be the hp limit for gas(pump, c16, etc..) with this pump with say either 1000cc or 1600cc injectors?

0Deatschwerks

Giving an exact limit of power for what this pump can do is going to be difficult.

There are many variables that are going to come into play that will determine what the limit of a setup is going to be.

Just to give you a few examples:

• tune
• type of fuel
• size of injectors
• baseline fuel pressure
• boost pressure
• pump voltage
• etc.

Using a quick, simple method for estimating fuel needs (this is by no means, absolute!):
Please observe that 43.5psi is the baseline fuel pressure. When you have a boosted application with a 1:1 fuel pressure regulator, the boost pressure increases the pressure of the system from the pump to the rail. So with 1 bar (14.5psi) of boost, you now have 58psi of pressure from the pump to the rail, and the amount of fuel the pump is able to deliver decreases as pressure increases.

We have a fuel calculator on our that should give you an idea of where you need your fuel system to be to make an estimate horsepower. http://www.deatschwerks.com/catalog/...alculators.php

These are the values for BSFC I use when estimating the size of injectors needed: Ultimately, it is going to come down to getting the parts installed and getting on a dyno and getting it tuned to see what the real world numbers are going to be.

To give you an idea of what the pump can support, we've had the pump installed in a few vehicles available through our dealer/installer network and the closest match to the turbo'd Hondas will be from the results of a 2.0L Turbo'd AWD Mitsubishi:

Hope that helps.

So what are the exact dimensions? I need to know if this will fit in the 06+ Civic Si fuel cage. The walbro was a tight fit and was actually a few mm longer and needed some slight modifications to fit. If this is longer and thicker then it will not fit without more extensive modifications to the fuel cage. I'm extremely interested in this for my 475whp Full-Race powered K20. I'm running 70psi base pressure returnless and this pump would be bad *** for possibly increasing boost. Thanks DW.

pumps seem like a great viable option to the walbro, but with the walbro being around 100 bucks and thebosch 044 being around 200 and able to support around 700 insingle form i would really hope they are in the middle somewhere.

also above you mentioned that at 14.5psi of boost youwould have 58psi of fuel pressure, shouldnt you really subtract the 14.5psi figuratively speaking as there is 14,5psi of pressure below the injector working against it, so interms of speaking you still have an optimum of 43.5psi working fuel pressure?

heavy duty

what to know more on them.( will they flow over 100 psi, what they flow at all volts, and on the walbros u can do some tricks to the pump AKA pull the check valve out to make it flow better. does this pump have one in the top of it.)
