i just noticed on the 1st page you were asking about rwkw figures with the mods - mine seems to have most, so i'll work from the intake onwards, and go thru what mine has:

-AUIII XR8 snorkel
-K&N panel filter
-EL intake system
-Stg2 Crow Cam
-Pacemaker 4499's
-Hi-Flo cat
-2 1/2" exhaust (lukey i think) w/ resenator removed

no diff upgrades or anything yet but that set-up has been dyoned at 130rwkw/172rwhp (stock EF's are about 95-100rwkw) - however that was with stock snorkel, and a 3" mandrel intake w/ exposed pod filter - so was a bit hot. i'm also looking at getting the vernier gear put in for my cam, just to try and pick up whatever i can. so hopefully that gives some people an idea on what gains they might get...

just remember different dynos read different figures..

pretty sure it was done at the dyno-day that all the FM guys attended last year sometime - so at least it might tie in with other results the perth guys have got

what extractors do you reccomend? PH4480's any good? or JMMrace series?

Fantastic thread and very helpful for all us 6 cylinder fans.

PH4480's any good? or JMMrace series?


Jmm Race seem to be the top choice with the Pacies a real good second. Apparently they're a similar style to the JMM Race.

As far as Thremo fans go, during summer those of you with the falcon series fans might be noticing the temp guage creeping closer and closer to the top,, there are 2 things you can and probably should do,,,

The AU series thermos mainly but the late E's as well have a problem with the brushes wearing out, and teh fan will at first only operate intermittantly, or not at all.. you can try blasting them with compresses air and degreaser, then drilling a small hole at the top of the engine case, and dropping some oil in there.

If your thermo's are on the way out, or you dont have any yet.
I, and all the other members with them(antony, eed-250, Fast futura, pauli, ect). Would recomend VOlVO thermo fans.

These have almost 3 times the air flow rating (CFM) of the ford E and Au series thermo fans. and have a much higher quality motor.

For a limited time we are selling them At
$80 for just the fan itself.
$150 with a thermatically controlled ajustable davies craig switch, and relays.
$200 installed, drive in drive out, inc setup of therm switch and fan.

thats Much more reliable, better cooling, including the switch and a High Quality Recon fan, For less than teh price of just the ford Thermo setup.

Pm me to organise transaction, or for more details.

i know they're availible for the 5.0l v8's but can you get timing gears for the i6 instead of timing belts/chains? are they worth it, money, power increases? etc?

EF/EL snorkels.

You say that you can fit a AU XR8 snorkel to the EF/EF 6cyl falcon by using the method in the ford mods technical brief.

I tend to disagree because I went out and sticky taped one so it would sit in the position it would screw down on. I then gently closed the bonnet slowly and to my suprise the rubber seal on top of the bonnet covers the top part of the mouth of the snorkel. Therefore rendering the snorkel useless with about the same airflow as the stock one. I then moved it up so it would fit on one original mounting point and shut the bonnet. The rubber seal just sits nicely behind the mouth but it isn't straight.

I went back into ford and exchanged it for a EL GT snorkel which in my opinion is larger and better flowing plus it fits to the original screw points.


So the moral of this story is if you are going to use an AU XR8 snorkel you need to mount it inline with the original screw holes and not back an inch or the rubber seal blokes the mouth, rendering it to be useless.

Cheers Luke, have a nice day!!!!!!!!!!

what the f did you do to get that out of your AU
i hve an Au wagon that has no where near that

Guys !!! From my experience get xorst extractors and a chip .If you get greedy rebuild the whole engine abd get a dev 7

While this thread is a summation, i think that the apparent issues with the auxr8 snorkle being blocked by the rubber on ef/els should be addressed as a yay or nay. I've read alot about this and it seems about 50/50 (or maybe its just the same ppl writing the same thing in many threads). Or is the ELGT snorkle the way to go, and if so, is it worth the extra money???

I have an old dyno chart for my EF Fairmont sedan daily driver.
Listing the mods done and result gained the bottom line is airfuel ratio. The only mod at std was K&N air cleaner and airbox mod.
At around the same time I did the 3" mandrel bent intake I fitted an XR6 fuel pressure regulator this is why the air/fuel ratio went way to rich as the computer had not fully adjusted and was running slightly richer. For those not having XR engines this mod was done because on an injector flow bench at the higher pressure(equivalant to std at full flow) the spray pattern was better then at the higher pressure the spray pattern was heaps better. OK for those who are unaware how the fuel pres reg works it holds pressure in the fuel rail and has a diaphram that is connected to manifold vacuum as vacuum is taken away it increases the fuel pressure the XR reg is the same pressure as the std one high pressure and 50 kpaor psi(I can't remember) higher at its high pressure. This regulator can be brought for around $100 new or used one should do. The difference when driven was the amount of low down grunt off the line as every time I gassed it off the lights it would turn the tyres and launch hard. Good value. Other mods not dynoed was the fitment of ss inductions intake *(an early version) now fitted with new style plastic one.
PS must be due for another run soon as this is 2yrs old.[img]{DESCRIPTION}[/img]NOTE no extractors Cam or chip fitted.

Great topic.. I've just purchased an el ghia... Just want to do a few minor things... Is there any way to do anything to an exhaust without the noise associted with 2.5 inches pipes etc...
