i have a friend that has an srt neon, i know i know F*** neons but anyway, it runs GREAT,, and he knows his stuff,,
i mentioned to him that the only way i can get my f22b2 turbo to push 300 bhp ((in the future )) would be to put around 600cc injectors in the setup.

i asked him what kind of crime i have to commit to buy 4 of these, he said he gave 40 bucks for all 4 of his off of srtforums.net (or .com).

is this normal? wtf kind of deal is that?

** he is using a TD04 turbo at like 18 lbs and he has 577cc injectors**

 

40 bucks seems very cheap for an injector unless its from another application that had a larger injector that would work... ie dsm 450's you can get for around 50 bucks a set of 4.

it either that or someone was just wanting to get rid of injectors for little of nothing.

since accords have resistor boxes oem installed right from honda you can drop a set of 450 dsms in with minimal work or even better source a set of 560's out of an evo8 as those also can be had reasonably as well.

300whp is possible on a 450's with the right fuel pressure, actually even a little more than 300 but your approaching the limit quickly so I would go larger if possible. Suprdave who tuned my car on the stock motor f22b1 a while back pushed 335whp out of some 450's but that was max'd.

 

He speaks the truth... I made a tad under 300 WHP on f22b1 BONE STOCK on 450s with stock pump and fuel system, just bumped the rail pressure a bit. for 300 id go with at least 550s though

 

i have this blue FMU thing, thats what this dude told me it is, i thought it was a pressure regulator but he said "this thing is crap it will just blow your car up" and he wants to trash it..

he said "these lean out at higher rpms and dont do anything for your fuel air ratio"

i think its better than nothing for now until i can get a standalone or piggyback fuel management.

any thoughts?

 

FMU's are nicknamed FakeManagementUnits by some for good reason, they are a bandaid... I dont care for them personally at all. I would rather wait a little longer to go with some real management.

Basically they are a rising rate fuel pressure regular, what that means is for every pound of boost it sees it increases fuel pressure at a ratio to that boost. The ratio varies by the disc in it. So say its a 10:1 disc for this example. For ever 1 psi of boost it will bump your fuel pressure by 10 psi.

This setup still will have a problem of the ecu seeing boost, it will not stop that and the oem computer/ tune will geek out seeing positive pressure. To get around this most often with FMU's people run check valves or various other low budget crap to bleed off boost before the map sensor sees it. Another bandaid.

Basically its half *** and no real solution to management, no real tuning, no accurate control of a/f, no timing control, etc.

As another disadvantage you end up running extremely high fuel pressure on stock parts in boost. Not to mention that bumping fuel pressure on them is only going to get you so far. The stock pump is not known for operating well at those higher pressures among other things.

Just for ***** and giggles to give you an idea of how much pressure we are talking about, say you have a 10:1 FMU... base rail pressure is around 40psi... you pushing 8-10 psi of boost. Your going to have 120-140+psi of fuel pressure on a system designed for less than half that.

Agian it will work, people have used them... its just FAR from ideal or even good. You would be better off pulling a ton of timing at the dizzy, droping in some 450dsm, and running a afc hack than an fmu.

Best choice is to source a p28 and look at some cost effective management like the s200b or whatnot cheaper setups people are unloading right now to move to s300 or the like. I would suggest some free or budget tuning solutions, but since it does not sound like free tuning software solutions would be something your ready to invest the time in to learn how to use and tune your car... maybe look toward a marketed product. Also check with whom you will go to for tuning, see what they can work with and go from there.

 

I see your a prelude btw, so when I refered to accords having resistor boxes to run dsm injectors... your prelude should have one as well fyi.

 

NO NOT "THE HACK" LOL...


Sup C? Hows things

 

hack is OG management what you talking about...

same **** different day meng, just taking parts of the car for some winter adjustments. new turbo, intake manifold, tb, etc... to address the areas currently choked on my setup. you know how it is, its never done. pm me sometime, shoot the **** about slow honda accords...

 

i found some 450cc dsm's for 50 bucks lol! weird, same price as mentioned.

 

use crome you dont get any cheaper than that. crome, freelog, moates.net chip burner and a soldiering Iron from radio shack = 100$.
