What next?

[galapogos01]

Well...

My EF auto has had the following done to it over the last few years:

Decent amount of headwork (but not XR ex valves)
Wade 1521a & vernier
Pod in airbox
JMM Race series headers into 2.5" lukey mandrel
Chiptorque custom tuned chip
JMM 3000rpm stall
3.9 LSD

which netted me 150rwkw, and just last weekend a 15.06 @ 93.8mph pass, first time at the track, in total street trim.

I guess my question is: what next? I want more, faster, now. I feel that i could get more of the setup with some good tuning - but dont know where to take it in melbourne. Lachlan did the chiptorque but he didnt spent much time given the cash i spent on it -- it still has a rich, hunting cold idle.

Suggestions?

[needfordspeed]

Get a unichip, and get it tuned by a reputable workshop (I got mine done at dynomotive and am very happy with the work they done, except the cold start, need to take it back still for that but i've been lazy), was the chiptorque tuned on a dyno? But before doing that i'd go a 6 throttle body manifold then get it all tuned at once. You could also try nitrous if you want to stay NA.

[old_mate]

definately go the bigger exhaust valves, more compression wouldnt hurt

Never been sold on unichips and the like, look at the edit software




manual


Turbo

i was ****ed about the ex valves at the time, but i needed the car back on the road. the compression was raised a fair amount (not sure of the exacts). i dont think i'd pull the head off just to change those.

the chiptorque was dynotuned at F1 motorsport in blackburn (Melbourne) by lachlan himself. he had about 10 other cars to do in 2 days, and i dont think a 6cyl fairmont was a priority next to some of the **** hot cars they had there! the chiptorque is an edit, its just the closed design that sucks, meaning noone can edit them bar lachlan.

should i get something a bit tougher cam wise?

id prefer to keep it auto at this stage...

[old_mate]

fairenough

just have seen good results with 4ltr heads with as much done on the ex as possible.

copy Grechies motor. lol. You cant tweak up the timing on it can you? never played with coil pack varietys

[EFFalcon]

did you take the LPG mixer out for the drags?

[galapogos01]

yup.

any other ideas? anyone?

can anyone recommend a decent workshop to tune it?

[Sundeep]

Tickford snorkel, stally, shift kit and hi-flow cat?

For all the moeny you are going to blow trying to get it right just to gain 1/2 a second, just put NOS on it and go for a 13 sec pass.

did you read the OP? :p i have the first 3. dunno how "high flow" my cat is; JMM mocked it when they fitted the extractors, saying it was too small. its probably clogged/burnt now from running too rich.

bah. i dont want a quick pass. i want a quick daily.

JMM would have put 2.5in flanges on the stock cat that has probably done high km's. Get a high flow cat fitted probably cost $250-$300 for a good magnaflow cat etc.

Get a lukey race muffler either straight through or with a 1/2in offset. The muffler you get with the off the shelf lukey cat back or Redback is basically crap compared to other lukey mufflers you can get.

Custom exhausts will outflow the off the shelf generic systems, it's just hard sometimes finding someone to spend the time and fit one up.

I got a custom system fitted on my EL fairmont. Went to 3 different shops before i found someone that would do it. tried out 6 different mufflers and was charged $150 less than a generic system. The gains were noticable over the 2 yr redback single muffler system.

its not a stock ford cat, but jmm reckoned the stock ones would flow more than it. its pretty tiny. ill take a photo tomorrow if i can be arsed.

it'd be nice if that was holding back a bit of power, cause its easy enough to replace.

not so keen on changing the exhaust. i like the sound as is, even though its a bit too loud for me these days.

keep the tips comin.

Take a photo of your lukey muffler so i can see whether it's the cheap muffler they fit on all the generic off the shelf systems, does it have a big offset from entry to exit (6-8inches?).

[yahoo189]

such a nice car... there was a build thread not that long ago for a Turbo. You can make them reliable. It would make a huge difference, and you could run it at a low boost so you did not have to do to much work on the engine...

[Kenaz]

Awesome looking car and it sounds mint!

[EFFalcon]

theres gotta be more in that engine combo... its got everything to make it quick so many a tune is really all it needs.

who finally did your exhaust?

This is the Exhaust shop, very good service.

it was definately a cheap off the shelf system. it is mandrel bent tho. it cost me $120 and i fitted it myself, then got a place to fit a new cat & lukey extractors. after deciding the lukeys sucked, i went to jmm. here's a pic. hard to see, but the offset is 6-8". its still quite loud for an off the shelf system.



here's a pic of the cat. once again, hard to get perspective, but those are 2.5" pipes - so the cat is only probably 4" wide. jmm said its the kind of cat they'd put on a 4cyl car. i thought they were just trying to sell me a new cat!

Shttt sorrrrrrryyyy I tried to help man lol. I see stally and "pod in airbox" there, but no Tickford snorkel or shift kit man.

yeah yeah, im not having a go. i have an electronic shift kit, and an AU s5 waiting to be fitted.

just compression tested it:

1 170psi
2 165psi
3 160psi
4 160psi
5 150psi
6 150psi

guess thats normal for an engine with 270k on it?

[Sundeep]

Isn't it good?

Try also poo kicker mods like one range colder plugs, smaller gap and AU injectors. If nothing else that stuff improves fuel economy ;)

Sundeep

[old_mate]

im afraid to do a comp test lol. Not sure how much variation is allowed but 20 psi seems a little high to me

You motor runs good at the front lol

[galapogos01]

allowed variation is 10%... so i guess its ok. they always get gasket leaks around 5-6, i guess its the poor cooling causing more wear on the rings. i also tested it with the fuel pump relay in starting from cyl 1 so it could just be excess fuel in the cyl diluting the oil.

are au injectors worth it? same or less flow rate? im conscious of up the tune (not that its fantastic as it is). already run 1 range colder plugs for LPG. havent tried fckng with the gap tho.

what do you boys think of the cat, is it likely a restriction? if i can be assed i will unbolt the exhaust and try look thru it.

[Christiaan]

im running au injectors on the au motor i just put in, and im getting amazing economy with NGK R spark plugs..

[galapogos01]

if the injectors flow less, your tune will be lean all over the range...

http://www.injectorsonline.com/indivprod.php?c=1

EL 185cc 18lbs/hr 37hp High $AUD 45.00 + GST
AU 205cc 20lbs/hr 41hp High $AUD 60.00 + GST

that says AU injectors flow more! go figure?

[galapogos01]

so does that cat look small to anyone?

[-jjM-]

The cat might be you'r issue.

It does look a little on the small size but I couldent see it causing an issue to flow, I recon its more so to do with a clog then anything as the 4cyl cat wont be adequate enough to sustain the 6cyl engine's needs.

There for collapsing and acting as a clog.

But if its done that then the car would run like a bag of crap, only one way to find out tho.

[EF_Frmnt]

au injectors flow more. you will need a retune if you just wack them in.
