Well i had a great night at the strip being nothing broke and car ran great. traction was an issue but the track was gripping pretty good which made for decent launches but still spun through 1st and 2nd gear.

All passes were done on Falken Zeix's 195's set at 18psi and runs were made with 3/4 tank of gas. Boost was at 8psi because i cant turn it up any more with the 370cc injectors at stock fuel pressure. Bigger injectors are next so i can up it to 15-16psi. My first run i babied it through and didnt do a burnout just to get a feel how things would go. ran a 13.7@110mph

Every pass after that was 13.1-13.2 @109-110mph except my final pass i made.
Final pass was a 13.06@109mph Here are the slips. I will post up two vids from my friends phone being i forgot my video camera at home.

Let me know what you think. This is with the setup in my sig.

good times

Nice times! The mph seems like it might be a bit optimistic for 8# of boost though.

nope seriously, im running only 8psi. i have a manual boost controller but its fully loosened so there is little restriction to the wastegate thats why its 1 psi higher than stock im sure. the car is definetly making good power and weighs only a little over 2100 lbs. with slicks the car even at this boost level is capable of a low 12 sec pass. after i get some bigger injectors the boost will go up to 15-16psi and max out that t25 which will only be good for another 35hp or so but worth it. then slicks comes next

Oh ok I didn't know your car was all gutted out. The calculators say 235hp for a 2150# car to run 110 which seems about right for a 9.5:1 w/S4s.

nice times, i'm hoping my t28 setup at stock boost will run at least that on street tires. with drag radials, i'm hoping for high 12's.

its not all gutted. All seats were in the vehicle. i removed all a/c items in the bay and under the dash. No front bumper support, and no exhaust on the car, its running open downpipe. Other than that the car has no sunroof and no abs system. I might be a little low at 2100 and something. I need to go weigh the car again since the extra weight taken off. i will weigh it later. Im pretty sure the car is at the 250-260whp range at this boost. being my a/f stays at the 12.0-12.5 range at WOT being no matter what i do to the settings there is no change which tells me the injectors are maxed.

Yes both the stock maf and 370s at 3 bar are completely maxed at 250whp. I'm surprised that you're already there with only 8# of boost though, even with the cams.

im running a z32 maf blowthru but yeah 370cc injectors. im looking to get the wrx sti 520cc injectors with clips I know but the car is making some serious power. im using the safc to tune it also. it runs strong and even on pump 91 octane gas. i will get it dynod later when i up the boost

I think 110MPH is about 12.4-12.5. I did 12.5 with my old T25 setup @ 110MPH. You need to get some slicks to run that quick though.

I run STi injectors @4 bar with a Z32 maf, I think its an excellent setup. You should really consider a calum or jwt maf as the safc won't be able to compensate enough for the larger injectors.

I ran a 13.3 @106.6 in October on my old turbo setup, t25 @13psi and S4s. I have a full interior and an 8.5:1 det engine though. I'm hoping to get deep into the 12s this year with my new setup, GTi-R t28 w/t04b compressor housing.

at 3 bar they are exactly 2X the stock injector size so i should be fine to just change the settings. not a problem at all. I think there was a guy that ran a 12.2 @110mph but yes slicks are a must.

Those times are very good. I am trying to think what the hell makes your car move the way it does. For a T25, that thing is hauling ass. Congrats. Who knows, first T25 into the 11's?:D

Edit: You sure that thing is not a T28? Lol.

haha. im gonna try for it. once i get those injectors. 16psi here i come. then slicks hoping to break the t25 record. maybe we will see. I figure if i was on slicks that night and pulled at least a 1.8 60' that would have been good for a 12.4-12.5 @111-112mph.

I figure once i max out this t25 at 16psi my mph would be at 115-116. im hoping that will be enough to maybe hit an 11. I will keep you guys posted on when i weigh the car to see exactly where i stand so far.

here are a couple vids guys, The race against the evo mr running 23psi of boost. was a 13.2 run at 110mph i beat him because i had a better reaction, his trap speed was 106 mine 110. the slip is posted, third one down the page. The race against the supercharged ford focus was a 13.1 sec run @ 109mph That slip is posted as well, the last one on the page. he ran a 13.7. Sorry the vids dont have sound for some reason, they were taken with my friends phone. oh well next time i will have good vidoes taken from my camera.

Nice run wtih my old t25 setup I made 12.7 @ 108mph at 10 psi but with 22x8 slicks and 1.73 60' . Good luck

no, an safc can only correct up to 50% more than what the stock ecu is programed for. an safc can safely correct up to 370cc injectors on a stock ecu.

wrong, there are others that have corrected 550cc injectors. when you look at 50% that is taking away 50% fuel. Its not 50% of what the stock injectors are. Its cutting 50% fuel. so if you have 520cc injectors. stock is 256cc. 520cc injectors minus 50% would be 260cc injectors which puts it right back at stock so


Another way to look at it is that if you have your stock injectors in there and you set your safc to -50% its going to correct the signal to the ecu to minus half the fuel in other words its going to only alow the injector to open for half the time. So if you have the 520cc injectors in there and its telling the ecu to only open them for half the time they normally would then what does that bring it to, 260cc. There are many others that have done this. Ive read up and studied on that.

And if that were the case then my settings on my safc for my 370cc injectors would be -50% for idle which it isnt and slowly drop down from there. Its not, my settings currently are -28% for idle and drops down from there, My high throttle setting is -13% and works perfectly at that. With the 520cc my high throttle setting would be around -25%- -23% and for my idle it will be -50% or close to that. The ecu has a tendancy to learn quickly and adjust fuel on its own too for idle purposes.

It kind of works like that, but not completely. You need to figure in the z32 maf. That will really throw things off, and keep you from reaching what your attempting. I would recommend the stock maf or bored maf, if you really want to use an safc for tuning purposes.

I tried using 550cc injectors, z32 maf, and safc for tuning. If you have an afpr, you really cant get much past 10-12 lbs. of boost. The trick to getting the safc to work with such big injectors, is to really hide airflow. The z32 will not allow for much, thus keeping you from running much boost. This only happens because the safc will change the airlow the ecu is seeing and it alters the timing curve severly. This makes the car a pig down low, and sluggish up top. This is the case with a z32 maf, not stock. Just my 2cents.hope it helps.

interesting, i get what your saying about the timing issue. i can see why. Well im gonna give it a try and see how it goes. if not i will just hold onto them and get a calum ecu for that setup. No big deal on that.

Oh and i can see why that happens too because since the z32 maf i actually have my setting for my idle at only -7% because if i go any more - its just lean and wont run hardly at all. I had to richen it up from the original -28 setting. it just wouldnt run. But the rest of the settings seem good.

I think an N60 maf might do just right with his setup. Maybe a calum basic ecu then tune it to spec with the s-afc?
