The mods:

05 sti
cp pistons + pauter rods + oem crank
cosworth 278/274 cams + supertech valvetrain
lightly ported heads + oversize valves
perrin gt35r kit .82ar + ewg dump tube
ssac fmic
borla hush exhaust
smc meth kit 100% meth M15 nozzle
utec + openecu/streettuner reflash by me
cusco motor/tranny mounts, all the group-n, kartboy, tic bushings
rps 6-puck + act prolite flywheel
kumho ecsta mx 245/40R17 tires
stock axles

22psi, 12-12.4 afr, 19-25 degrees of timing on-boost.

I have boost turned down till my crawford air/oil separator arrives next week. So I spent some time this weekend tuning AVCS, air/fuel, and ignition timing at lower boost levels... I think the results are worth it!

amazing, what power range were these pull made? 22psi on methanol I would guess around the 450 range?

did you have another non OEM turbo before this, if so how does the throttle response compare? Thanks.

Looks crazy fast, the power comes on and all of a sudden you have to shift

[jays05]

I ran a 21psi enginuity log through dataloglab and it said 460whp... a 25psi pull was 488whp.

The top-end pull and top-end airflow with this motor is just insane. I went from the stock turbo straight to the 35r, but I ran the 35r on the stock motor before getting the built motor 5k miles ago. So I can see the difference between the stock motor and the built motor (or more specifically the built heads+cams). And the difference is big... spoolup is the same, peak tq is less, but it holds more tq to redline and flows a LOT of air.

My AVCS map is pretty aggressive and causes it to build boost really easily... so light throttle boost response is nice, but my gas mileage sucks. In the beginning of the video you can hear it spooling under light throttle.

Im very curious how you have your knock sensor set-up....using the 2 step limiter and all......and with a noisy built motor. PM me if you are willing to shed some light.

Anyways, car seems awesome...awesome man

I am running a UTEC, and I have the knock sensitivity turned back around 20 points I believe. It pulls a degree of timing after a 2-count of knock. I was running these knock settings for 4k miles before the camshaft broke, and when the motor was apart, there wasn't any evidence of knock... so I feel comfortable with these settings. Usually the first pull will be full of 1-counts, but after that as long as I keep the pistons hot, the knock sensor stays pretty quiet. According to my logs the stock ecu is running full timing except when I hit the 2-step...

I do have a txs knocklite installed, but it's connected to an oem honda civic knock sensor, and that didn't work out as well as I had hoped it would (hey the sensor was free...)

your car is super quick..

nice build

[STIVendetta]

Very nice! Good Job!

[whitestar]

Nice setup!

[STIcyrus]

Pure SEX I can't get over that launch lol good work man, you should make an outside video of you launching it like that. Anyways thanks I'm gonna go to sleep happy toniight lol

[CenCali07STI]

awesome setup sounds amazing and acceleration looks unreal.

Why did the cam break on the previous motor?

Because the scooby gods were pissed? I dunno why it broke.

I am really afraid about the axles... I just need to hold out another week or two till I can afford the driveshaftshop axle bars. The launch actually doesn't feel that bad, nice and smooth with no wheelhop... but the shift into 2nd gear is brutal and will break something eventually.

[scoobaru]

nice, that made me wanna build my car more!
