Obviously one wouldn't run E-85 on a black setup, but suppose one was to use pump gas with a goal of low to mid 4xx whp.
I'm thinking this is achievable with DW 1k injectors and given the scenario above.

Thoughts on the matter?

 

I think it's just achievable with 1000's....I'd pick up FIC 1100's or DW 1300's.

Edit...I have FIC 1100's and output ~400whp and my IDC's are 86% or so....

 

Why wouldn't ou use e85 on a black? I'm sure that's probably the best way to run a black.

 

I'd love to, but it's just a pita to drive so far for the ethanol. I have it in my car now, but it's just not practical. My black will be here by the end of this week I'm guessing. So I just wanted to get an idea.

Side note: I found a great website to calculate my fuel setup

Had a friend that used this and found it to be very accurate.

 

you can make over 500 whp on 1000's and the right fuel pump on E85

 

define "the right fuel pump" because i'm pretty sure the math says a 255lph will not flow enough e85 for 500whp so you must be talking about something else, right?

 

FWIW on stock fuel pump, my DW800's are at 97% IDC on pump gas (w/ standard 10% ethanol added), 414whp dynojet. By that math 533whp would be possible on pump gas, stock fuel pump, with the 1000's.

Get the FIC 1100's and a boost-a-pump and you're ready for E85 and the limits of the stock bottom-end.

 

I agree get FIC 1100cc. DW1000cc are a PITA.

 

you can't achieve 500whp or close to that with stock pump and nothing done to the electrical of that pump. The math is just not there i'm sorry. I did the math for your set up, considering stock pump with nothing done to it, and you yourself are pushing the envelope of the math according to your power levels. and this is with very conservative BSFC and 97% IDCs. The math says you would need a 206ish lph pump which i believe the stocker is somewhere around that. Does anybody know the actual LPH rating for our stock pumps? and please source how you know this.

edit: i'd be interested to see what math you're basing this off of though.

 

The stock Evo X fuel pump is no slouch: http://www.amsperformance.com/ams_ev..._pump_test.php

With a boost-a-pump, it's definitely possible to make over 500 WHP on the stock pump... until you blow the pump out.

 

Here's a pretty reliable source on the Evo X fuel pump:
http://www.amsperformance.com/ams_ev..._pump_test.php

Most importantly, it shows the relationship between boost and fuel flow. Lower boost setups (like big turbos) should be able to reach a greater HP on a given pump/fuel.

 

yeah the evo x pump seems to be better than the others. however, there is a flaw with that test that AMS ran on the pumps. I will be posting results of my weekend project in our local forum TJ. oh yeah, even that chart shows that the stock pump is only good for about 190 to 210 lph depending on the boost pressure. which if he's making 414whp i'm assuming it's somewhere between 25 and 30 psi. which would raise the total pressure anywhere from 60 to 70.

ps. too bad you didn't guess that on my build thread

good point on the turbo sizes. I wonder what turbo schides is runing? however, like i stated, the test by AMS if flawed on the pumps. but it does show a good relationship between the pumps though.

 

Yep, and you could potentially drop your fuel pressure a bit at the cost of atomization to get more pump flow, but that's a game of diminishing returns. Trading pump flow for required duty cycle, basically.

And SON OF A *****, I forgot nobody has really posted results of using a Boost-A-Pump on an Evo X. Good thing there wasn't a prize I missed out on not guessing that or anything

 

A BBX. He's currently running a race gas tune in preparation for the dyno day at MAP tomorrow.

DW1000 are easy as pie to tune i have done 5 sets in the last 4 weeks not an issue with one of them
