    Thread: USRT Fueling Solutions

    1. 09-26-2008 03:26 AM #301
      Hey Scott, still having the time to help others with their fueling problems? [IMG]http://**********************/smile/emthup.gif[/IMG]
      What's the flowrate on that 413? Does it flow better than a 044 setup?
      Would there be any reason (performance wise) of choosing one setup over the other?
      BTW, WAI rocks (50% pharmaceutical ethanol)

      That's what I'm here for, Elie.

      Yes, sir. The regular 044 is rated for 200lph at 5bar whereas the Motorsports 413 is 200lph at a massive 8bar! The 044 is typically comfortable up to about 600bhp whereas its stronger cousin can handle 700 - 800. I don't have a flowchart for the mighty 413, but here's what the 044 does:

      Sure, if you want more than 600bhp but less than 800... the 413 is the ticket.

      Yer damned right about that!!! Btw, did you advance your timing or lean out your mixture? Or, have you "only" turned up the boost? Btw, USRT sponsor's Vortex's new Water/Alcohol Injection forum. [IMG]http://**********************/smile/emthup.gif[/IMG]

      The 413 seems to be a no brainer at higher fuel pressures then.
      My actual question was how it compares to a dual 044 setup, forgot the dual .
      If I concluded right, the dual 044 setup will outflow the 413 but won't be able to maintain or provide flow at higher fuel pressures.
      As for the WAI, I haven't advanced timing or leaned out the mixture yet since I'm still running a C2 chip, as a starter.
      I'll have an smt7 shortly that will help me fine tune my setup. I will be posting before and after dynos in due time. But it already made a lot of difference.
      For those who don't know. I ran 10 psi non intercooled and was seeing ~10-12deg timing retard. WAI brought it down to ~0. Gained power instantly.

      Ah, yes. The 2x Bosch 044 will double the amount of flow that a single can support. That + a surge tank would be the way to make some ridiculous power. Of course 2x 413 would do even more, but I don't know of a VW cylinder head that can flow enough air to support 1500hp, etc.
      I've sold several 413 pumps to guys running 5bar fuel pressure and up to 2bar boost. Here it isn't so much about doing 800hp, etc, but ensuring that the finest fuel atomizatoin was achieved. This = more torque and snappier throttle response. Both are critical for the intended application -European rallycross:

      Btw, the doubling of fuel flow will only occur if you run the pumps in parallel (i.e. 2x separate fuel lines). Putting them in serial (i.e. one after the other on the same line) will not increase flow or pressure at all. [IMG]http://**********************/smile/emthup.gif[/IMG]

      Okay, what changes did you make to fix your air/fuel ratio problem? You're very welcome for the help!

      well i doble checked everything again before buying the fuel pump, i installed the fpr and the fpg,by the way the fuel pump it is good, checked for any blown fuses found 2, check for the cause of fuses blowing, i found that the wires in the oxygen censor were connected wrong, two of them were misplaced,the fuel pump and the oxygen censor use the same fuse,,after that the idle stayed between 800 and 900 which i wanted,so i regulated the fpr to the same bars than the stock one,and is runing good i still need to check again just to make sure evrything it is the way it post to be. i think we are lucky since it is my first proyenct and to be doing it by myself and a friend of mine, so far we are doing good, thanks again for the help.

      OK, lemme pick your brain(s).
      This is the engine:
      G60 PG block, OBD1 ABA head.

      And it has a stock ABA fuel rail with the 3BAR FPR and Corrado G60 Greentops.
      Before I switched to the crossflow head I was running a G60 head with a Corrado 3.5BAR FPR and fuel rail and the car seemed slightly faster than it does now.
      Things you need to know:
      Stock G60 Digi1 running 10-15PSI of boost.
      Stock Greentop 'raddo injectors
      Stock ABA fuel rail with ABA FPR.
      Things I need to know:
      What is the flow rate for the greentops?
      Would a 4.5BAR FPR be better for my needs?
      Would larger injectors be better for my needs?
      What do you recommend to get the most out of my setup?

      well scott tried to take your advise and a stock intake with a 044 will not support anything over 500 whp without going lean, tried a 255 walbro intank and a 044 intank as well and the bothe made a diff vs stock intake but the problem is the pickup you, you need to have so much gas in the fac tank for it not to sputter, i will be going with a swirl pot that uses the stock vr6 intake to fill and a 044 as my inline.. with a -6 feed

      The Walbro intank will provide no benefit whatsoever and can only cause problems.

      Why does the walbro intank add no incremental benefit when used in conjunction with a Bosch 044? I am planning to run that setup

      Is anyone from USRT even active in this forum anymore?
      Why are they still the FI sponsor?

      USRT is an official sponsor over here, so don't shy away.
      Scott is really a great guy to deal with, very standup and very knowledgeable. It's just that he might not have much time to spend over here.
      Just pick up the phone and give him a call.

      Thanks for the kind words. It's totally true that USRT is a) still "here", yet b) way too busy to keep up with Vortex. By necessity, wholesale is our main concentration. With that said, we'll definitely be back within a short while. There'll be some new hires taking over forum promotions and customer engagement while I manage the company from a higher-level view.
      For the time being, folks can reach us by phone: 856.456.3335. Or, send us an email and we'll jump to assist.
      Thank you,
