Cool Customer: 2008 STi - STAGE 2 - 314whp / 365wtq @ 20psi (12.3 @ 112mph & dyno sheet)

Vehicle: 2008 Subaru STi

Customer: Rosario (iwsti memeber)

Modifications:
- AMR BMI Cold Air System
- AMR UEL Headers & AMR Up-Pipe
- Grimmspeed Electronic Boost Control Solenoid
- Catted Downpipe
- Catback Exhaust

Dyno Sheet:





Notes:

I just got a PM from our customer Rosario this morning. He went to the track yesterday with his Ford Mustang buddies and should them what a Subaru can do. He says they were extremely impressed. He layed down a consistant 12.3 @ 112mph. I asked him for a picture of the timeslip but knowing him he will come on here and answer any detailed questions himself.

This is a good example to explain what MPH you would run in a 1/4 mile drag strip with this horsepower rating. Also give an idea of how our dyno reads for those who always ask.

Boost: 20psi
Octane: 93 octane

For those who ask:
-NO LAUNCH CONTROL
-STOCK CLUTCH

Rob, this is very, very impressive. Especially with a catted dp!! Can you convince him to take that piece of chit dp off, put a non-catted one on, and go for even faster times? You see how badly the top end is affected, but the true end results were fantastic. Imagine if the power held off to redline, I think my 12.19 @ 112 would be in trouble

Good job guys!!

From his post:

"hey all went to the drag track yesterday first time either with a bunch of mustangs. my 08 sti was getting dirty looks in the morning. after laying down good times they were really impressed by how quick these subbies are.

by mid day they were all asking what kinda work was done to the car. just a intake, exhaust and tune, i told them. some guys had 10-20grand invested in their cars, and were only laying down mid 12s, with slicks. ok enough talking here r the numbers. sorry didnt scan the print out, will do that tho.

mods:

cobb short throw shifter
AMR cai intake
cobb catted downpipe
perrin quad tip exhaust (not liking it)
AMR unequal length headers
AMR up pipe
1 step cold plugs
tuned by Rob at AMR dynod at (314.4hp / 365tq at 20psi)
93 sunco


my first pass on the draggin ever was 12.5 at 109.7
stayed consist at that a few times, had one bad pass at 13.0 110.2
best of the day was

12.33sec at 109.84mph
r/t ... .664
60' ... 1.70 (best was 1.61)
330' .. 5.101
1/8 ... 7.899
mph ... 87.90
1000 ... 10.295
1/4 .... 12.336
mph ... 109.84 (best was 111.8)

thanks for hearing my rant, also just wanted to thank rob for doing one hell of a job tuning the car. "

oh and if he's still on stock clutch, it's only a matter of time before the OEM crap clutch goes. 14K miles and mine finally went.

Rob, your tunes are awesome! can't wait to get my car back up and running so we can do some long distance tuning!

weird, 47K on my odo and over 300 drag race passes and lots of spirited driving through the beautiful mountains and my stock clutch is still in decent shape.

Bet he could get that a bit lower. Thats a really nice running car that probably makes fantastic torque. I guess we finalyl have a vehicle capable of keeping up with those pesky bolt on Evo's. Does the customer want to go with a race gas/meth tune?

Rob,

If boost follows torque why does the boost come on slowly compared to other Stage 2 setups out there? I am not saying this in a bad thing at all, more than likely this is how you were able to obtain some impressive numbers on a stock turbo.

I would assume this is due to the larger ID of the headers and uppipe you are running to make more top end horsepower. Is this correct?

Alot of it also has to do with the AVCS on the exhaust side adding to the peak torque.

but you do not have an 08 STI. The 08 STI clutch is NOT the same as our 07 STI which we've also had 1 more year to beat on and track without any issues or slippage.

Good observation. I did not lean on the AVCS tuning the vehicle made good power so I did not dive into the AVCS as much.

This is what many do not realize. Instead of tuning a stage 2 car for a hard hit,you can keep work and heat out of the system early so that performance shines up top
