I suprised myself at the track wednesday.

I ran a 13.2 on a stock turbo w/ boost controller and s-afc II... plus the usual bolt ons.

ALSO, I was on a full tank of pump gas(93 oct) with heavy @$$ 18" Racing Harts... going again tonight on my stock wheels with some racing fuel(110 oct) :rolleyes:

I'll post the time slips when I get a chance. Any comments?

wow get some real EM and your car will love you

BTW great times for a stock turbo

how did you tune your safc, and to which afr target?

ken

That's real good.:eek: What was your 60ft time? Do you know your WHP?

My boy "Colombia"(don't know his real name) tuned my car with the s-afc II which shaved 1/2 sec of my 1/4 mile, but he wont tell me what he set the afr to... said "it's my little secret"
http://pic15.picturetrail.com/VOL602/2857105/5755259/73841829.jpg
And my 60 ft was a 1.791

Never got it dynoed

This thread has "Stock turbo" and "quarter mile" in it.

waiting for the obligatory V6turboTA comment

That is a nie time... I bet if you went with a UTEC or ECUTek that it would be slower... I dunno just have a feeling. Go 12's!!

what was your trap speed?

what was your trap speed?


Are you serious? It says the trap speed right in the title to the post????

Put down the crack pipe :lol: ;)

Take off the BOV.. It'll give you slightly better running times..

Take off the BOV.. It'll give you slightly better running times..

I second that suggestion. I removed the BOV from my set up and gained 2.5mph and .24 in the 1/8 mile.

2.5mph and a quarter of a second from a bov going back to sstock... that couldn't possibly have been slightly better driving??

That is a nie time... I bet if you went with a UTEC or ECUTek that it would be slower... I dunno just have a feeling. Go 12's!!
Why would a UTEC with a proper tune be slower than a SAFC and MBC?

Ya never know.. maybe the setup he has now is making more power but with unsafe AFR's.

how could a bov make such a large 1/4 mile difference?? the only difference i could possibly imagine is going from atmosphere back to recirc and that keeping the turbo spooled on shifts... but that big a difference seems impossible to be all bov...

i agree, variable with biggest probable change in that scenario.......

human operator.

You idiots talking about the bov are uhh... idiots

Results from tonight?

Also, I'd be pretty nervous about not knowing AFR's. For $50 or less you can probably go to a dyno and get the setup dyno'd (not tuned), and get an idea of AFR's throughout the rev range. Unless you have some kind of knocklink/J&S, and can confirm that there is no det.

Wed. when I ran the 13.2 I ran it consistently :) ... Tonight I ran a 13.3 at 102, :confused: guess my heavy 18"s get better traction. Used racing fuel this time, and temp. was about the same too... :confused:

nice times your making just a hair more power than me from your trap speed best i was able to get this summer was 101.5mph, but i would get her on a dyno to see what kind of afr your at, by the way how much boost are you running at the track?

They recently got an AWD Dyno in Orlando at CFT (Central Florida Turbo), so I just may, but I know the afr is fine, it's just that the guy that tuned the s-afc II doesn't like to give out his "tuning secrets"... He works for HDMmotorsports.com ...they mostly tune honda but the guy has talent.

and I'm runin about 16 psi

If I could just take the better numbers from each run...

....that'd be nice :banana:

On your first slip, what car did you run against? Must have been FWD considering his horrible 60'. His ET sucks complete ass but with a pretty quick trap. Just curious to see what it was.

wow awesome times keep it up :banana:

but I know the afr is fine,
But how do you REALLY know w/out actually testing it?

But how do you REALLY know w/out actually testing it?
Trust, I guess. The time slip obviously shows the difference. He tuned it right. I'm confident in him. He ran a 12.9 in a Del Sol :D .

what brand headers?

The first run was against '69 Camaro that could not launch his car. The car sounded mean, vicious even, but he now understands the beauty of All-Wheel-Drive :lol:

I think I have seen you running around in Sanford. I have a silver '02 WRX with bronze wheels. Nice runs! Post this in the SE forum.

Got them off Ebay... No-name.

Yeah, I work in lake mary and am in Sanford a lot, so probably saw me. Don't remember silver w/ broze wheels though, next time get my attention, swerve into me or something.

anyone can lean out a map and make more power, you have an AEM intake which means you are already running lean because your MAF is off then you further lean it out by tuning an S-AFC w/o a wideband or dyno pull. Trust is a lot cheaper then a $4000 engine replacement

Oh, Who said is was w/o a wideband? :confused:

and who said he leaned it out? :lol:

I have difficulty believing you did that on 16 lbs of boost, but I really don't care..still an excellent time. good job
SCOTT

Oh, Who said is was w/o a wideband? :confused:
if it was done with a wideband you would know the AFR as it's not really any secret

ride: you don't make power going richer, especailly with only 16lbs of boost

how the hell do 1.7 on 18s, shaare your secrets :)

I was driving while he was tuning, so couldn't pay much attention to what he was doing. All I got to do was floor it when he told me to :D
He definitely leaned it out, told me I was running way too rich, but honostly I left the tuning in his hands since I don't know anything about it.

my point was that you are trying to say he goes lean with an intake, and leanER with an safc. how do you know what he did with the safc--a positive or negative correction to get the desired afr? even more shockingly--perhaps even tune around the intake's offset to mafv? :eek:

people like to think you need "big ass" engine management to get the job done on these cars, and i don't subscribe to that point of view. my thousands of lines of utec logs along with timeslips and tunes like this one bolster my opinion.

ken

engine management IS the way to go! i don't trust those afc's! and without a tune with a wb 02 you have no idea what your afr really is.... period. afr should not be a secret.... and i'd be hesitant to let someone "tune" my car that isn't gonna tell me what they did. especially if you're paying them to do it. utec is nice because you have the knock alarm so you can pull out some foot before you grenade the motor. imho i'd rather pay for em once and tune it right than blow a motor and pay at least twice the cost of em to rebuild it.

i've also "read" of some good gains from adjusting timing.... can't do that with the little afc's!

all i am saying is that people should keep an open mind--there is more than one way to skin a cat.

I think I'll have it tuned again at cft(central florida turbo) on the dyno soon, I'm curious to see what kind of whp I'm putting out anyways.

What else can I do to get faster, besides the turbo upgrade?

you can very likely gain 20-30 hp with increasing timing advance. a couple of degrees here and there do indeed add up.

otherwise the general power adders end up freeing up as much restriction in the intake and exhaust tracts as possible. really that's a matter of smooth, fast plumbing.

finally start taking stuff off and out of the car! :lol:

ken

<spooky halloween voice>Seeeeccrreet AFRRRRRRR... ooooooo!</>

He should also be worried about his tranny and this point.
13.00's is when mine went bye bye. Just stick with the stock clutch, I made the mistake of going with an exedy hypersingle 6 puck.
Also, how much hp you getting from them seatbelts, turbo timer and gauges? j/k but i got hazed for listing non power mods in here so i have to pass it on.

you do understand that using a racing fuel does not create more power, but it creates a more controlled burn, better for use in a higher compression motor where detonation will occour easier and destroy the motor, if you do not need the higher compression fuel than it is better to use a lower octane(more uncotrolled exsplossive burn) and make more power due to it :eek:

How many MPH did it add? I took 1/2 second off my time with a better launch, MPH stayed about the same.

Pete

Why would a UTEC with a proper tune be slower than a SAFC and MBC?

My MBC and vishnu EMI with TBE, UP, Pulley were faster than my AP stg 2 with the same mods.

How many MPH did it add? I took 1/2 second off my time with a better launch, MPH stayed about the same.

Pete

My MPH went up from 99 to 102 with the tune S-afc

Even with a broken up-pipe weeks earlier I had a 2.2sec 60 ft & ran a 14.4s while my mph still increased to 100MPH leaking plenty of boost, just saying the tuning helped my top end.

Also, how much hp you getting from them seatbelts, turbo timer and gauges? j/k but i got hazed for listing non power mods in here so i have to pass it on.

ATLEAST 20 WHP I'm sure... maybe more

boost gauge- 6 hp
oil pressure gauge- 3 hp
egt gauge- 2 1/2 hp
turbo timer- 1 1/2 hp
seatbelts- 6 hp +1 hp if it's buckled ;)

Sure you can, you just don't have the granularity of other forms. Leaning it out advances timing and richening retards timing. And s-afc with a a good datalogger such as the delta dash which can pull timing to where you need it (again, global changes; you can't change the shape of the curve). I've had good results with it as had others.

Again, a custom tuned reflash or UTEC is better, but don't discount a well-tuned s-afc.

And for the record brand new 205 shorties are only $500, $1500 for the 257. No need to try and scare anyone.

Those headers are made in Korea by WANLI. I just installed a set on my 02 wagon.

how did you shift? if i take all my gears to redline i usually bounce off the limiter just before i finish in 3rd. you obviously had to shift into 4th, so what are your shift points?

I shift between 7000-7200

I have a video of my 13.3@102 on pc but I don't know how to post it... who can host a video?

I only know what was on the box they came in...It was an impromptu purchase from a friend of someone at skycarracing.com (they're a local wholesaler). The headers completed my exhaust sytem mods (PDE cat-less up-pipe, PDE down-pipe with hi-flow cat, MBRP cat-less centre pipe and exhaust.) Noticeable performance improvement!
