3. I THINK around 12 but dont quote me. Heaps of threads on this topic - do a search!

that wouldn't be stock. no way. way to lean for stock. did you mean after safc? im planning on running 12:1 with safc...

thanks for the directions...!

5. I think inasnt meant that the dump he had did not exactly fit the front pipe he had. I don't have this problem because I don't have a front pipe and am getting a 3" one made up when they put the dump on (on sat.  ). When they make it up they can just make it to suit the dump - but he had no problems with it fitting onto the turbo. Anyway I think it was only a little bit off and the exhaust place would just cut your flange off and rotate and reweld to suit!!

[/b]

ahh no i understand the difference between dump pipe and front pipe. i was on the understanding that the dump pipe and front pipe were the same things (wrx speak) now that i have a full understanding of the new lingo, i will most likely need a front pipe and dump pipe...

cheers, i'll be interested to read about your install and results post saturday!

1. I have posed and so has black33 pics of the dump pipes in this thread.

original (oem) dump pipes, not the arrow diff ones...

2. The oulet flange for the r32 and r33 turbos are the same, dont know about the r34 tho. If the r34 has the same turbo as the r33 then yes it will fit.

T3 afaik?

3. my stock a/f were runnin near 10.0, which is rich as a bitch!

yes, rich as - but this isnt too much of a surprise. could you send me your safc settings pls???

5. the outlet of the dump pipe to front pipe is angles differently to the stock dump so i had to get my front pipe cut and rotated to join the new dump, no dramas with that part anyway!

this wasnt the case with black33 then seeing as though you had the same dump pipes???

6. what r u doin sneeking around the vic section??!! hehe kidding!!

i know that i dont browse all sections of the forum ... in which case i think everyone is missing out on lots of relevant discussion topics.

i mean this thread for instance, had nothing to do with VICTORIA, besides the people who created it, ArrowDiff are located in Sydney and the topic of discussion is very relevant to everyone..."me no understand"...

firstly i have the rest of the system, 3inch front, high flow cat and 3 inch rear. blacks exhaust is the stocker!

as for me sending u the s-afc setting, that aint they way to do it man, u need to run it on dyno and adjust it according to the a/f ratio readings or else u r gonna reck your engine if it runs lean!

only way to find out if the dump will fit is to take your stocker outand compare it to the r33 1!

i know thats not how you do it

i just want to get a basic idea of where your pulling out fuel...

also, on the safc isnt there a function where you can literally cut fuel when you back off the throttle so as you dont get backfires???

well my s-afc setting basically start at 3000rpm with -3% and sorta progresses more and more - till 7000 rpm where its -15%.

as for the dec-air function i havent got it to work properly

WELLLLLL, finally installed it on Sat. along with a front pipe and had my cat opened up to 3' front and back!

Have to say though, haven't felt any difference - maybe 'cos the weekend was so damn hot here in Melboure - will have to drive it on a colder day and see if I can tell if it did anything.

u basically got a bigger exhaust and u felt no difference?

WTF!

I felt better spool from new 3inch exhaust before dump pipe was on

I always had a super dragger exhaust on there but only from cat back. On the weekend I only had the front pipe done and the dump installed.  

I swear, if anything it feels worse. I get a flat spot over 4500 rpm when stretching 2nd and before when I took off hard in 1st, it struggled to keep traction but not anymore? don't get it?

the weekend was a bad time to test the car, as it was hot as a mofo!

u should come over and drive my car and see the differences, i can wheelspin my 255's at only 7psi boost even if i take off slow and then floor it all the way through 1st

Thats a good one, I rekon SAFC myself, and just put water injection on the stock cooler. but then with a fmic, you can run more boost..

its a win win situation.

I got a 30rwkw gain from tuning the safc

what do you reckon comes next for me for most power increase - an SAFC or a FMIC

(don't say both)

I would go FMIC, bypass the s-afc and get a power fc.

I am planning on selling my s-afc soon and gettin a power fc.

I don't think I want to go as far as a PFC, too much $$$$$.  

Keep me in mind when you sell the safc if I haven't got one by then (when would that be?)

What power increase (from where I'm at now) do you think I could get from the intercooler and from the SAFC??

i am gettin a cooler by the end of the year, then i will get my pfc.

For now if u can get a s-afc second hand for around $400 i would get it then upgrade later like i am

cool, will keep an eye out.  

do u know where can i look for one second hand for $400 apart from our forums?

u can get em new from http://www.nengun.siteblast.com/

for about $520 i think, or just keep an eye out on here, and skylines downunder.

ex-static, 30kw from an safc tune? that's abit rich isnt it? was there an inherent problem before the safc tune? did you raise boost? any other mods that came with the safc install and tune? 30kw at the wheels? mygod... was it done on the same day and same dyno!? id hate to think how much power a new turbo gives you!

black33, you'll be very lucky to get a 2nd hand SAFC for $400, i've been waiting for weeks! best i've seen is $480. Noone will go lower than $500. At the end of the day, i think im going for a daughterboard for a couple hundred more and get access to fuel and ignition mapping and tuning.

as for choice between SAFC, i guess it all depends on what you want out of your car down the track? i guess you wont lose much on resale value with an SAFC but you've still gotta install, tune and then remove later on if you do decide to go PowerFC. i think in all cases, your best bet is to do it right the first time, that way you get maximum enjoyment, least headaches all the time...

450 phil was selling them for second hand...

[franks]

ever to be repeated?

[inark]

theres on for sale now by white_r33 480 inc install... but i think nismo GTS-X has his eyes on it so u better hurry should be able to get 450 and u pay for the shipping which will be about 11 dollars something.

[franks]

maybe after your boost spiking exercises your ecu's decided to retard timing?

there is no way a dump pipe and front pipe has decreased power for you unless your car is NA!

I'm thinking, maybe now that I have the full exhaust that they fuel ratios are really screwed and I'm gonna try gapping my plugs to 0.8mm. Am I on the right track, any other explanations?

I suggest u go straight away and get sum ngk 0.8mm plugs. Then get that s-afc and get the thing tuned, and u will feel the difference.

When i got boost controller put in and upped boost to 10psi it was missfiring upto with the normal plugs!

[meggala]

black r33 wind your boost down a bit and see if it help wind it down to 8 psi or so more boost doesn't nessacarliy maen more power then get the s-afc tuned.

franks here in melbourne we have had some very good results with the s-afc tuning 15 20 rwkw iis gain quite often.

exstatic doesn't need to jsut ify the gain cause most of us were there when he got the gains and saw them with our own eyes

meggala

[ex-static]

Franks,

Same Day, Same Dyno, a little bit of boost. from .6 - .7bar

It wasnt just my car either Grim on these forums, had a good 20-25rwkw gain on the same dyno, same day, same tuner.

Great results can be had from an safc when tuned right! I guess it depends on your budget, and how far you want to go in the future.
