dual walbros usually get high 7s, low 8s on the supras. Dual 044s get a lil more.

I assume you are using ID2000s like I am. Be interested to hear your impressions on idling on pump gas and at what rpm.

 

I did 628 w/ E85 on a DD which is close enough to 700 on a DJ. The pumps did fine, it was injectors that were getting close to the limit.

this was with precision 1200ccs

 

i'll be doing my e85 tune as soon as the snow clears off the ground so we'll see how far i can get.

 

So Jay from JayRacing has been in contact with me in regards to my results using their pump. I have since sent the wally I replaced to him to have it flow tested. results were similar to what you see in that flow chart.

I am thinking, I am not getting enough power to it via the stock harness/wiring. He is sending me another pump with new wiring harness.

Even if I get the same results I am seeing now, I have to commend Jay for standing behind his products. I won't likely see the dyno again till may or june, but I will update.

 

so your wally looked like the wally in that chart or like the Jay racing pump?

 

my wally that I pulled prior to the jayracing pump looked like wally in that chart... mine dropped off a bit more suddenly on the upper end. PM me your email and I'll send you the chart I was sent

 

where are the results on the DW300 from all the shops?

 

even the results from other platforms seem to be lacking and I know ppl are using them.

I would think that it would have to be a big difference in overall whp to justify basically 2x the price of a standard gss342 walbro. Esp considering that most kits need prtty high octane to run >600whp which a 342 can take you to.

 

that sucks.

I just want a pump that will carry me upwards 600whp.

Sounds like the DW300 has more advantages than just peak WHP.

My base FP is in the 50psi range at the moment but I will be dropping in some 800cc deatschewerks which will lower my base FP and thus increase my LPH output.

 

you could always do that with a 85$ walbro and a 230$ 20A boost-a-pump. that will run about 320LPH at 55psi. So run a 35psi base FP and you can add 20psi on top of that and support 800cc injectors at full tilt.

The DW alone runs 320LPH at 40 psi, so if you only needed 5 psi to get to your HP, that would support 800cc injectors by itself.

Get a 200$ DW301 pump and 230$ 20A boost-a-pump and you can run 1000cc injectors at full tilt up to about 60psi.

Of course this is all rough math, but viable alternatives to going $$$ twin pump.

 

hmm aeromotive has the same pump as well..

^ those will be on the shelf the end of this month, while the warranty may not be as good as DW, it outflows everything and the price will be cheaper.

 

Hmmmm... I wonder if Charles can use this one in his CJM twin pump assembly.

 

no, the twin pump uses a smaller sized 255L out of like porsche or something. they are not 342s

 

^ partially correct but bottom line, no none of the pumps that are coming out will work with the current CJ Twin Canister design

 

So… for E85…would the Aeromotive or DW fuel pump be able to accommodate 500whp? Or would a twin fuel pump setup be absolutely necessary? Along with 1000-1200cc injectors too.

 

Just keep in mind that overdriving the pump creates excess heat that the pump was never designed to deal with, and can prematurely kill the pump...and void any warranty it had. the aeromotive and dw are not the same pump

 

can you cite 1 example of this? I couldnt find 1 example over dozens of forums and a ton of threads on BAPs. All heresay without any proof of actual failure.
besides its not overdriving until you are boosting at whatever PSI you want o have it come on at. DW rates their pumps at 18V right on their spec sheets as well.


You could probably string it out to 500ish with E85. But why cant you make 500 on pump 93 octane? Thats not very much hp. The horrible gas mileage doesnt even make E85 worthwhile unless you are making well north of 700whp. At that point, twinpump or bigger is needed.

 

Anybody have a Flow vs Pressure Chart to Post?

Thanks

 

Arizona gets 91 octane at best and even though I’m sure we could squeeze 500 whp out of it I’d prefer running E85 at that point.

Also…I literally have an E85 pump across the street from me, like less than a quarter mile from my front door.
