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.

yeah there is a start delay of 0.5 sec

Tested works good, had to redo map table like this 0 100 200 300 kpa

Blocked hood vent, 10 dollar mod!



some random shoots with good camera

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

Anton,
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.

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

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

so far no problems, just did some pulls and AFR seems to be stable at redline 11.2 with meth, but still injectors at 101% maybe raise fuel pressure? i'm at 70 psi peak

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.

Incorrect. Bernoulli's principle. Read it learn it love it.

Quote:
Bernoulli is the guy who discovered that for the flow of an incompressible fluid through an orifice to double, the pressure must quadruple. Put another way, the change in flow is proportional to the square root of the pressure ratio. I think it's safe to say that all of us who play with fuel injectors get this, and in fact a quick Google search will bring up numerous injector flow rate calculators that are based on this exact principle.
http://www.injectordynamics.com/size14.html

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

I'm sorry I didn't catch this earlier, but how are you verifying fuel pressure during the run again? Do you have a sensor or a gauge in cockpit? It seems easy to just wire in a relay from the battery tied to the meth pump. You just need to tee into that 8 gauge to the meth pump and splice the fuel pump wires temporarily.

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

I do stand corrected on Bernoulli's principle.. Thanks for the reminder!I do not refute this. I guess based on the manufacturer provided charts based on fuel pressure changes that the DW 1100's may be underrated as to their size. I will post up the pressure corrected chart from these injectors to compare. I'm just do not have that info at hand right now.

Still 101%? Damn. I'm in the 8x% range with a little more boost.

Is fuel pressure dropping up top?

I'm running 40-42 psi base with engine running.

Time for a Bosch 044?
