Default 09 WRX stock turbo 293 whp, 304 wtq

Event: dyno tuning
Location: Innovative Tuning. Buffalo, NY 14216
Ambient Temp: ~57
Elevation: ~700 feet above sea level
Weather: sunny
Tires: all seasons

Car: 2004 WRX Wagon
Tuner: Mike at Innovative Tuning
Dyno Info: Mustang AWD 500 SE
Peak HP at RPM: 293
Peak Torque at RPM: 304
Baseline hp/tq for a stock on same dyno:
Target Boost: 20 peak tapering to 14
Target AFR: ~11.5 tapering to 11.3
Fuel: 93 unleaded. No external injection.
Engine/Power Modifications: see dyno graph
Driveline Modifications: none


While I was tuning an LGT our mechanics were tag teaming Darrell's 09 WRX.


They installed:
KS Tech 83mm CAI
GS 3 port boost control solenoid
DW 650cc injectors
Defi Red Racer boost gauge
turbo blanket

After installs:


The car already had a Perrin TMIC, GT Spec header, walbro pump, and upgraded turbo back exhaust.

After the installs we got the car on the dyno and I started tuning the new intake in. When I started getting into boost I noticed spool up was a bit lazy, but I thought it might just be the header with big primaries. Then I did a full pull and noticed both spool and power were lower than expected. It was getting late, but we stuck around to sort it out and we're glad we did because the power the car made in the end was great. We rigged up our smoke tester to the intake and found a hose off the turbo inlet was leaking heavily at a union fitting. After clamping the connection we retested the system and found no leaks. After hooking the intake back up I did a pull with no changes to the tune. Spoolup was better, the car picked up 40 ft/lbs of torque, and I had to cut the pull short because it was trending lean due to the change in airflow. After dialing it in, here was the result for the 93 octane pump gas tune:

Wow. Wish I had an 09 WRX to play with as a toy car so I could DD the Bug.

Very impressive!

Howcome you guys chose to use the 83mm kstech as opposed to the 73? I only ask because i will be swapping out my AEM CAI with a KS tech.

+1, I'd like to know as well... 83mm seems like wayyyyy overkill

That's a fair question. There are a few reasons:
1) I have no trouble at all tuning their 83mm intake despite the size because it's very well made.
2) It leaves plenty of room to grow for the future. Using a part and then upgrading it again in the future wastes money. Making suggestions that help our customers avoid wasting money makes them happy.
3) Less intake restriction means less pressure differential between the inlet and outlet of the turbo's compressor.
4) They're the same price so there's no downside.

^^ I was going to type the same exact thing. The real question is "why would anyone buy the APS 65 or 70mm intakes?"

There is no "overkill" on the intake if its made properly. The KSTech seems very well engineered.....I talked with the owner for about an hour on the phone and he is infact an engineer.

If I was making intakes i would ONLY sell the 83mm......there really is no point to the smaller ones.

On a related note...the MAF scale on the 2010 STi is increased significantly from previous years. The scaling approaches 400 g/s.....im unsure if the intake is actually ~70mm sized.....have any idea mike?

Very nice results. Very similar to what we've been seeing with the 09's here!

How did that Perrin TMIC fit? Any clearance issues with the slave cylinder?

My perrin tmic was bought used. Has a large gouge from the slave cylinder. No boost leaks fortunately.

i had issues with my perrin tmic hitting the slave cylinder. i had to remove it again and reclock the turbo a little. now there is about 1/4 inch between the them. it seems alot of people have installed these and never put their hand underneath and check for clearance issues. no need to ruin a 700 dollar tmic.

Ron that's a good question. I'll try to remember to measure the housing when a 2010 STI is here.

Thanks Ed. I didn't specify, but the customer had installed these parts himself before he brought the car here for the other installs:
Perrin TMIC, GT Spec header, walbro pump, and upgraded turbo back exhaust.

I'll ask him if it hit.

It didnt hit when we installed it....and i got the 83mm cause he didnt have the 73mm in stock and i bought it at the last minute and i figure what am i gonna do flow too much air lol? A cai isnt really necessary for the vf52 but when your trying to squeeze every little amount of hp out of your stock turbo setup every little bit helps. I know similar stage 2 cars made 270ish on his dyno so i am very happy with my results. Those extra goodies gave me 25whp

A stage 2 09 WRX on the Cobb stage 2 93 octane map made 230 whp on our dyno. Admittedly the car did not run well on the off the shelf map for whatever reason. At 2 less psi than the Cobb map ran where the car makes peak HP it made 246 whp on my tune. I don't have a dyno graph for a stock 09 WRX on our dyno.

I gave Darrell this aggressive map, a more normal one and an autoX one in case he gets the itch. He asked me to really push this setup, so I did, and then gave him maps I'd use most of the time to make the setup last longer.

the car does have 650cc injectors right? hows there IDC? were they the reason for only 20psi?

with the HP graph it looks like the VF still wants to make power. its a awesome looking graph by the way!! ive seen vf52 fall hard after 5-5500rpm. shes pullin all the way

High 80s idc's i think but other way i was happy with my results....i almost got tuned on race gas but I heard a couple horror stories about transmissions on these 09s so i figure why push it too hard? I think im gonna just keep using stock clutches too so there is a little leeway on the drivetrain. I try not to drive this really hard all the time like i did with my dsm cause it cost 4x the money to get trans work done.

Anyone know where i can get some quarter mile times for vf52s...Im looking to break some records on pump gas here in the NORTH EAST lol or burn out my clutch trying

Yea this is the best time of year for turbos cause those hot days sure aint good although traction is a bit better when its about 60-70 degrees vs 40-50
