Has neone got one of these or been in an NA skyline with one? i am thinking about purchasing one but not sure what sort of power gains to expect, i really just want to richen my car up so i get some nice backfire action happening when i back off. Ne help?

Cheers

u want to richen ur car???

um, try using crappy fuel, that should do it.

i get a fuel pops when theres a crapper batch of fuel.

[NA_R33]

yeah isnt that basically what ur after, a richer mixture which allows the car to run cooler and benifits a few other things and in return gives u more power, or am i miss informed and to get more power u need to go leaner??

[NA_R33]

i read a whole article on it and it said that richer was better for more power and cars come out of the factory lean for better fuel efficiency, the whole thing didnt really make sense to me as i used to ride motor bikes and the way to get more power out of the was to lean them out so it was all a little confusing for me.

Richer gets u less power but protects ur engine, skylines tend to run heaps rich, any richer well you will get heaps of flameouts of the zorst

I'd be keen to know the gains from having a S-AFC fitted to my NA Syline too... Anyone got one???

[NA_R33]

ok im definately getting one, i found the new version (version II) on an american website and it will cost me about 540 dollars to get it here. I got a quote to fit it at 100 bucks and a mate of my dads is gonna dyno it and tune it for me, all should be done in 3 to 4 weeks hopefully, let u all know how it goes.

There is one on ebay right now, brand new with a starting bid of $500 and no one has bidded on it. I would buy it apart from being dirt poor and not knowing the full benifits that it will offer.

lean = power

rich = protection (as nismoman18 said)

Go for it john i want to see what kind of gains you get!!

[pstanbis]

Im with greg on this one - go for it - certainly can't make it go slower...

[nismoman18]

yeah actually i know someone that has one on their non_turbo car, it gets rid of the airflow meter and you can get a good gain in power etc. if you set it perfectly! i am considering one myself so if u get one b4 me tell us how it works out. bware though if u set it lean, do not rev to red line, the power will come in much earlier and u risk breaking things at high revs!

[Nismodified]

it gets rid of the airflow meter?

the safc intercepts the signal from the afm and alters it before sending it to the ecu or something like.

having an air flow meter is essential.

using a fuel control system that uses Map sensor instead can do away with the airflow meter.

[nismoman18]

yeah thats what i meant hehe me dumbass

Mine came with the S-Afc. But I dont really know what it does or how to use it. I suppose I should get it dynoed to see how much power my car has. Mine is set to High Throttle but dont know what that means.

[NA_R33]

ok fella's, sorry all my mods are on hold for the time being, i have something special brewing.

on the later series, blue screen edition, the safc's have two interchangable fuel settings.

i guess it could be for things like good fuel bad fuel days, summer/winter temperatures, power/economy.

[NA_R33]

no, i have read that, they have 2 selectable and modifiable (is that a word) maps these are high and low throttle, i would say high throttle was the last thing that was tuned and or the only thing that was tuned. At a guess...

Hi all... ive asked around a few places regarding a SAFC

i was told that ill get atleast 8-10% gains

they put a SAFC (or VTEC eqivalent**) on a accord and got 12kw from it

** cant speeeel for crap

[NA_R33]

talked to a guy at revolution race gear a few days ago, they said on a satria GTI they got a 22kw gain.
