hey guys

just wondering, is there a table or conversion method to work out what size injectors can support what power (hp)?

i did a quick search and it has been suggested that 1cc supports roughly 1hp, so 700cc inj supports around 700hp

some1 also came up with; cc x 6/5 = hp (700cc x 6/5 = 840hp), which seems quite high

please confirm :)

cheers,

Andy

stock gtst injectors and a FPR will do 250rwkw

well i've already bought the injectors and fuel pump, and i want some breathing room in the event that the high flow makes much less than 250rwkw and i get bored and decide to strap on a bigger turbo :( . but i wouldn't be aiming any higher than 280rwkw, cause i can't afford a rebuild :) . so the 440cc injectors should still be up the task

so why is it that i've read articles in hpi etc that have cars with a power output of about 500rwkw but they're using 1600cc injectors?? do injectors still work accurately even when they're being used below the level they're designed for?

Personally I would not want to be using any injector (or fuel system for that matter) at more than MAX 85% of its capacity. In case shit happens, it is probably a good insurance. (having said that how anal and redundany you want / need to be with your fuel system depends on what what your doing with the vehicle and how far you want to take things), $$$ add up quickly :D

yea mate but how many 1600cc squirters are they using??

many racing/high performance cars use big injectors to suppliment their apetite. they are called 2ndary injectors. and it is very common in rotors. e.g. they may be using a few 500cc injectors then use a couple of 2000cc injectors to beef up the support.

i personally dont know y they do it. perhaps using all 2000cc squirters may be too expensive or inefficient....

im sure someone on here might know?

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
