yellow 440 injectors
hello,what is the maximum power output u can get from 440 injectors?would i be dreaming in trying to get 330-340 bhp with the standard 440 injectors in place?i know ill need a afpr to accomplish this but am thinking of putting in bigger injectors if they will max out before 320? anyone know?there must be a few of u that have maxed them out......what figures??? thanks in advance.:thumb:

i was told yellow 440s are good for 340/350brake with supporting mods , on classic full decat fuel pump fmic etc and a remap

hmmm,ive heard all sorts,300 tops,320,350???? would be great to hear it from someone who is running them to the max and at what power figures were accomplished? thanks for the comment.:thumb:
and its running the 350bhp Hence going to get them flow rated darc |
ive heard about 330 is the limit for 440s

ive also been told its not a great idea to run them at 100% if that helps mate

Try andy forest perfomances website he has a section with power outputs and what mods are needed to reach em

With the mods you`ve mentioned and a good fpr you should achieve 330 or close to it,but every car is different and to TBH your pushing the limits of many of the standard parts on your car,rods,pistons,crank,clutch,gearbox etc on a classic are close to there limits at this kind of power and there life expextancy will be grately reduced beacause of this.

I did 335bhp/333 ft.lbs STi 3 Wagon and there was nothing left. Obviosly with an FPR.
For interest 550cc on two separate cars were struggling by 400. |

if your lucky mate. try and get a good set of 500cc blue injectors
reasonably cheap to get, but at the same time hard to find i was always told 330/340ish tidgy got 343 with his 440cc injectors dont know if he has an uprated reg though. 550cc injectors tend to hold value these days |

i have 440cc fitted at the mo, but sent off for these 500cc so's not to max them out.
maxing will decrease the life of them. with a fpr, even more so |

99gw... check these bad boys out!:-
Subaru Impreza version 5 / 6 550 Fuel Injectors on eBay (end time 25-Jan-10 20:02:17 GMT) I'm sure they are Power Enterprise jobbies - one of the best brands! Plus seller says he had 'em off JGM so, if so, will be totally fine. :thumb: Even if you end up paying the full £250, I'm sure you'll not find cheaper (esp. PE ones!) |
yes look good ;)
they are power enterprize Simon |
There you 99gw, a personal endorsement form the great man himself - what more can you ask for?! ;)
|
Do those really need no special caps? The tops of injectors look different to UJ/Nismo style injectors?
|
typical......havent got the funds at mo!:cry: that is soooooooooooooo typical!:rolleyes:
|
99gw, never mind.
If you do get a FPR (and I've been advised from a respected specialist that really you are better off with the Fuelab one), then you can run 440cc inj. at a minimum 3.5bar static (instead of the std 3bar). This should allow them to run at c.470+cc, which should allow 330bhp - as borne out by harvey, above. |

In that case, I'd just get mapped on your 440s and see what figure you make! At the end of the day, it's gonna be around the 330 mark give or take. I'm sure the 'number on the page' won't bother you once you rip it up the highway for the 1st time! ;)
Re the 550 route... Flawed thinking if you feel you could reliably run the 550s on the stock OEM FPR - you'd really be better off, in the long run, to have the new FPR in addition! to the 550s (your OEM one is at least 10 years old and there'd be no way of infuencing how it will control the 550s...). After all, with that sort of fuelling (410bhp potential), you really wouldn't want the inj to run erratically/lean! at high loads, simply all because of an iffy old FPR - curtains! You'd hate yourself. :( |
