Maxed Out!

[Grechie]

I wont see 160rwkw without a Chip or ECU change

I pretty much made same power as the 1636, with the 1636C977B, but with a better A/F Ratio & bit more Torque which should result in better track times. My car with EDXR6 ECU + XR6 300KPA Fuel Pressure Reg is Leaning out at the end of 4th, i wont make more power even with a bigger cam, without a chip or engine managment, SHATTERED! Ahh well

The Car doesnt lean out as bad as the 1636 did, and it leans out LATER in rev range which should help track times, but for power, im maxed with this engine management...


Bring On Calder!!

Grechie, what injectors are you running?

[sphell]

Nice work.....what about putting some blue top injectors in? Would that help or make it run rich in the lower revs?

[TUF.EB]

Good work man, nice results

A Unichip or Flash tuner should get it running a bit more power and see some better AFR's

Should run a pretty decent time, although your last one wasnt too bad either!

Hey, im running injectors from a 94 EDXR6

i wouldnt have a clue, i was under the impression that injector change wasnt needed on the i6's unless you go turbo?

I will look into that CAPA thing for the E Series now... but yea thanks i hope to beat that time !


cheers

If ya running out of fuel and the injectors are at max, then bigger will help.

yeah thats true, would you know which would be best to suit my situation ? or will any bigger then 21 pound be better?

Get it on the dyno and get the operator to measure injector duty cycle.
Anything over 85% is starting to get beyond safe.

Grab some AU Blue tops and an XR6 regulator. They flow a bit more, might be good for an extra 7-8rwkw..

hey i already have a XR6 fuel pressure regulator, so all i need is the AU Blue Tops, sorry, but were are they found, which AU's ?

[Gunns]

get your hands on a set of bosch 775 (blue tops) they come out in GT's, Sprints, HSV's, and 4cycl magna's. Try your local wreacker.

[Grechie]

thanks gunns, do you happen to know what lb these run at ?

at 300kpa they will run at 24lb.

[Christiaan]

The only thing is, it won't have a huge effect until you get a chip and tune to use the extra fuel properly.. It'll run rich down low and give you a bit more fuel later on in the rev range..

[Grechie]

ok thanks guys, so...which type is better, bosch 775 (blue tops) or the AU Blue Tops? i know i will need a chip eventually, but for now im looking for a quick easy fix for my leaning out at 4500 onwards.

[Gunns]

If your O2 sensor is working properly the injector size should not matter, as the O2 sensor will detect there is extra fuel getting in and shorten the injector pulse to bring AFR's back to normal, that is the whole reason for having the O2 sensor to control the AFR's

[Grechie]

i have a brand new oxy sensor i bought recently from repco (like 3 weeks ago) , dave (SLOWEA) recomended it

[Gunns]

Just don't go throwing 30 or 40lb injectors at it cause it will be outside the ecu's clabration range

[Christiaan]

I think the AU blue tops off a standrd AU I6 are only slightly bigger than standard. 21lb?

The Bluetops are 24lb and deliver quite alot more fuel..

[snypereb]

Nice work grechie wolf is your friend.

hey !

So the bluetops will run @ 24lb? or 21lb?

i was under the impression that XR6 ecu + fuel reg runs the standard injectors @ 21lb.

[TICKFORD_XR6]

very nice
so is it worth getting the 1636c977b over the 1636?

hey , I couldnt tell you, as im busting the same power as a 1636 because im leaning out.

so does anyone know, is the AU Blue Tops 24lb or 21lb? and can i get them from ANY AU series...

[Christiaan]

Nah Grechie.

There are two different kinds.

There is the bluetops, as specified by Gunns which are from AU XR8 engines, magna's, etc.

Then there are the AU injectors i was talking about. They are all blue, and physically smaller than the E-series I6 injectors. They are from AU I6 engines. And flow more than the e-series injectors.

Try the AU ones first, then grab blue tops with engine management as the next step.

[Qwikcorty]

does your fuel pressure stay constant when its leaning out? may be your pump too if it hasnt been replaced for a long time.

19.63 lbs

[Grechie]

so there .63lb better

[Christiaan]

yeh grechie, but dont forget, to do it right you would go AU XR8 Bluetop injectors (24lb) and a unichip of some sought.

Dave (Thanatos) had roughly the same setup as you and managed 175rwkw(?) with a unichip and the bluetop injectors.

[Stav]

They wont be big enough for your application.They flow 200cc/min. You need 249 cc to produce a but more power.It should idle ok as its not a huge change.Talk to powerflow injection.Theyll give you what you need.

[Stav]

Set a realistic goal.Going to big will have the car give more top end power but be a can of worms to tune low to midrange and idle.
