You also have the activation delay you could set if you did see boost for a split second during a shift or if you wanted to use this with FFS.

Damn
What wheels are those? I would say works emotions at a glance. What is he offset/ size?
I pretty much want my car to look like yours but not as clean or as fast |

You're car is so ****ing clean and stealth. It is the **** in my book! Really what all Tarmac driven Subarus should be. So unsuspecting but relentless should some so called fast car pick on it! I'm bad but it is fun to embarrass other drivers some times. Idiots that pick on my XTI, usually regret it and I'm sure some cry Do you really want to block off that hood scoop? That will create more drag and I think that hood scoop flow is not bad for the engine compartment even with a FMIC. Almost like a Venturi effect from the volume of both the front grill and the hood scoop. The constriction is the exit at the fire wall, the air speeds up and helps evacuate all of the air in the engine compartment. |

thanks man, about the scoop i was reading that people saw improved intake temps with scoop being blocked off "some where on iwsti" i gotta find the link

Without a sealed tmic, the scoop adds drag. It also pressurizes the engine bay reducing cooling flow through the radiator. With a tmic, there is still a little drag, but the intercooler slows flow through the scoop minimizing the effect.
Multiple tests have been done over the years to prove this. |

I installed a hood vent from KSTech along with a custom plate a few years ago with the idea that it would help vent the positive under-hood pressure and increase airflow through the radiator/FMIC. Obviously doesn't look stock though so if that is important to you perhaps running an RS or painted carbon one would suit your needs, and might be marginally better than forcing air into the engine compartment with the scoop.

so I got mine, I hope you ("got yourself a pump")
will plug it to stock fuel controller do a test, and then will hard wire it to 100% duty with fat wires and then do test again! I think ill prove everyone that different wires wont do **** new toy for quick logging Last edited by Bariga; 11-21-2012 at 04:07 PM. |

those pumps are awesome. I swapped an aeromotive 340 out for the Walbro 416 (or 460?) E85, my old fuel system was so taxed, the AFRs richened up 2 POINTS!

A lot of people have already proven than there is a voltage drop through the controller, even under low amperage/load. Go throw a DMM on the pins at the top of the pump hanger. You'll save yourself time from trying to prove the world wrong

installed the pump! Went smooth had to trim the plastic tip of the pump tiny bit and bend the bottom bracket! Soldered the wires and used 2 layers of shrink wrap.
Using stock FPC for now, and just tested it at idle sounds little quieter than DW300, and makes noise like old CRT monitor |

What injectors are you using? I know that ID's do not have good response to fuel pressure changes. I know this because I chose to run older disc style DW 1100's because they respond to fuel pressure changes. My 1100's will flow 1300cc's at 4 bar/ 60 psi which will give me the fuel requirements for 500WHP on E85. Along with a Walbro 400 E85 pump direct wired with 12 gauge wire.

ID1000's and ID2000's perform great all the way up to 100psi base pressure, WITH correct latency and flow data all the way up there. You are misinformed. |

No, what I am saying is their flow does not change as much as other injectors at different fuel pressures. I know they flow well at all pressures. What I was saying is that you can get higher flows from higher pressure with some DW injectors.

Basically, your 1100's -- assuming the 1100cc rating is accurate -- can only flow at a very theoretical max of 1283cc with the stated pressure increase. 3 bar to 4 bar is a 33.3% (1/3) increase in pressure, which means a 1/6th (16.6%) increase to flow rate, or 1100 * (1 + 1/6) = 1283.33. All injectors are subject to the same principles of fluid dynamics Because I love math -- note that the ID1000 and ID2000 flow goes up by ~16.26% and ~15.73%, respectively, when pressure is increased from 3 bar to 4 bar. The theoretical increase should be 16.6%. Not a coincidence Last edited by lancelucas; 11-22-2012 at 06:07 PM. |

If you use taps you can just remove it. If the duty cycle goes down then its likely not the pump. |

Is fuel pressure dropping up top? I'm running 40-42 psi base with engine running. Time for a Bosch 044? |
