2006 STi - Retuned by Airboy
« on: October 22, 2008, 04:09:15 pm »
Well after 4 different trips to see Sunny, I'm finally 100% happy with how my car drives.  Big thumbs up for Sunny taking time out of his schedule to help out after 3 different intakes, header rattling, and some random mechanical issues associated with the intakes on the car.  Can't thank him enough for his on going support to the subaru community and providing a reasonable alternative to expensive tuning.  Not taking away from Lightspeed or Rocket Rally, they are amazing too, and have helped me quite a few times when I was stuck in a rut. 

Current Power Mod List:

1-Cobb 3" Turbo Back Exaust (no cat)
2-Mad Dad V2 UEL header / Up-Pipe
3-AEM CAI (swapped from stock, K&N Short Ram, Stock w/ moto elbow & K&N panel filter, then to AEM CAI).
4-Walbro 255lph Fuel Pump
5- Inginuity Road Tuned via Rom Raider

For those that need recommendations on an intake, please do your research and don't end up like me :(  Should have bought the AEM cai from day 1.

I'll let sunny post up the graphs, but running 18.5 psi, with 11 afr.  Making 285ish whp / 340ish wtrq.  Car has a clean bill of health via the mad scientist Airboy!

Out of curiosity, do you know what stock STI's are putting out on Sunny's road dyno software?

He should have my graphes as well. Mine is completely stock. Post if you do Sunny
There's no replacement for displacement

I'm interested in the boost/torque graphs since I've been eyeing the Maddad V2 Header.

I believe stock STi's are in the 220-230whp range using Sunny's uber-graphs.

I can't wait till he has had little more time to play with '08's...

To the OP, do you remember what your injector duty was at? I plan on doing a very similar setup and am trying to decide if I'll need injectors.

Ideally I'd like to see an 08/09 STi with headers and downpipe (maybe inject/pump) so I can see what I should expect.

Let me see what I can dig up.....

06 STI, Invidia catless DP, Cobb CBE, AEM Intake, UEL headers, ~45F temp
Boost and AFR


HP/Torque estimates Low air temp helps :)


Stock 04 STi with  rebuilt engine, ~64F temp.  Don't get to log many Stock cars...
Boost and AFR


HP/Torque estimates


Comparison I can has torque? ;D

Gain 50 ft-lbs, ask me how! :-)

Sunny, please! Such poor grammar. It's "I can has torques?"

You probably won't need injectors at our altitude.  I have an 06 and my IDC's are low 90's IIRC.  The 07+ flow better than the 04-06 injectors.

Yes sunny does rock, even with a tune that needs a little bottom end work, the upper end kicks assay. My buddies mustang with a glass pack and headers now sit in the dust with my stock WRX (re-tuned to stage1)

With your mods, shouldn't you be boosting more? what's your IDC%? I thought with catless, CAI, and headers, you'd be able to see 19.5-20.0 PSI... Even in Calgary

I should really make a trip to cowtown, just for this purpose...

Oops... is this thread jacking?
I think we need an "Airboy Review" Section.

He may be able to but I would guess that Sunny has determined that higher boost levels don't net much, if any, gains over 18.5psi.

I'm starting to wonder if an UEL header, or any header for that matter, will give you torque sooner due to the increased airflow.

as Sunny stated, Injector upgrades are probably not worth the money on a stock turbo.

I purchased the UEL header and up pipe when Mad-Dad had the 25% off sale, (520 shipped to my door).  The labour involved to put it on... shop it on in 3 hrs, but they said if they had to do it again, it should take 4-5hrs (had 2 people working on the car).  So for all the effort, to see 10whp/trq, I would go with EL headers next time around.

I've had a chance to boot around in the car with the new tune over the last few days, and the peak torque kicks in earlier than my stock header/intake setup.  Feels like the car inhales and exhales better (pardon my terminology).

Sunny tunes conservatively and safe, I wouldn't want to run more than 18.5 psi and im not sure if 20 psi would even make significant gains.  Just want the motor running healthy for the rest of its days.

Did you notice any difference in the way the car sounds with the header?
