The Real Monster: GT3076R 2009 WRX

We finished the 91 octane tune on the 2009 WRX GT3076R setup. We are on stock engine, and transmission pushing 18psi, making 316WHP / 319TQ. After upgrading the transmission, we will tune for race gas and run about 24psi targeting 400WHP on stock engine. The car is very responsive, full boost is about 3500RPMs. Engine response over 4000RPMs is amazing !

Setup:
GT3076R single scroll turbo 0.78 A/R
Tial 44mm wastegate
HKS SSQV blowoff valve
Custom uppipe & downpipe
Tomei unequal-lenght headers
Custom 3" exhaust
Custom intercooler w/reversed intake manifold for best response
Custom oil cooler Koyo radiator
Custom fuel system w/RC750cc injectors, walbro fuel pump
Carbonetic twin plate carbon clutch
Vipec EMS - now plug & play !

EVO X pushed beyond 600BHP
















We completed initial testing & tuning for the EVO X GT3582R AEM EMS setup. Next is heat isolation, airbox fabrication, and cosmetic finish for piping. We will also need a 6piston big brake kit asap!

AEM 1050 box was used as piggback running fuel/ignition/cam timing/boost control. Stock canbus ECU is controlling drive-by-wire and everything else.

Setup:
GT3582R T4 twinscroll turbo kit
Cosworth cams
Stock bottom end
3" turboback custom dual titanium exhaust
Ultimate racing walbro fuel pump kit
RC750cc injectors
AEM EMS - NO MAF!

We boosted 15psi initially, made 352WHP on 91 octane. But pushed it to 385WHP @ 19psi and finalized pump gas / low boost tune.
















We achieved 465.9WHP @ 24psi boost on race gas! This is over 600BHP assuming %25 drivetrain loss. We will see how long the motor holds under extreme race conditions, this car will be doing time attack at 2010 season.

track tests will follow, stay tuned !

Redline Time attack round2 Willowsprings May 30-31 2009

We are back from the Redline Time Attack round2 at Willowsprings, the big track!

After breaking the ring & pinion at round1, Kearny Mesa Subaru setup the new rear end and it was pulletproof! We had exhaust manifold issues but managed to place 7th in the street class. Before the last Time attack session, we were only 1.5 seconds away from 3rd place, rushed to weld to cracked manifold with the help of Fontana Nissan but didn't make it at the grid on time..

Here is a summary of the 2 day event;
Satuday practice session1 - 1:38.750
Satuday practice sesson2 - 1:36.710
Saturday practice session3 - no times due to exhaust manifold leak
Sunday practice session2 - 1:36.450
Sunday Time attack session1 - 1:33.749

Results

We missed 3rd place by 1.2 seconds.. We could have ran 1:31s with more practice, this was our 1st time on this track. Owner/Driver Cenk has a total of 6hrs of track time experience, with more practice we should be more competitive! Stay tuned..

Thanks to our sponsors; Kearny Mesa Subaru, DPR Racing and C-West.

GGT Front Mount intercooler kit for 2008 STi now available

Our new front mount intercooler setup is now available for the 08 STi.

The intercooler core is from Precision turbo and rated at 575 crank HP. ATP turbo supplies aliminum piping, silicone couplers & Tbolt clamps and we do fabrication & welding in house. Powder coating is optional.

Key features:
- Anti-clockwise air flow; charge side piping always stays cool
- Mostly 45 degree bends; Turbo lag compared to top mount intercooler kit is only 200RPMs
- Stealth look; best for those who wants to fly low

Notes:
- Half size battery must be used; optima yellow top recommended
- Bumper beam must be removed or modified to fit the core; beam modification is recommended
- Does not come with blowoff valve flange; customer must weld flange of choice

Dyno sheet & more info

Retail price: $1400

options:
- Brushed raw aliminum finish: $100
- powdercoating bright red or black: $250
- HKS blowoff valve flange welded: $50

Please allow 7-10 business days for delivery, all kits are special order.

2008 STi Test & Tune with Tomei ARMS 7760 turbo, Custom FMIC kit & Cosworth intake manifold

We had installed an AEM EMS back in Sept. 2008 on this 2008 STi. Customer asked for more power with minimal turbo lag and we recommended a Tomei ARMS 7760 turbo along with RC750cc injectors & re-tune. Below is the dyno graph for both setups. We achieved 306WHP peak HP compared to 274WHP on OE turbo both running 17psi boost. The spool characteristic of the ARMS 7760 turbo is similar to OE but maintains 17psi at the redline.


















After looking at the air intake temperatures (sensor located right on the Top mount intercooler), we decided to switch to a front mount intercooler as the temps climbed up to 190F. When cold, sensor was reading 70F, by the end of the run it was at 170F-190F range. We custom fabricated a front mount intercooler kit after looking at the options that were on the market. We managed to cut some corners and the turbo lag compared to TMIC was only 200RPMs!!



















We gained 55ftlb torque & 50WHP at 4000RPM (see above dyno graph), and 9WHP peak HP and hit 315WHP.

Intake temperature issue was also solved (the sensor is now right on the charge pipe 2" away from throttle body) with minimal turbo lag.

Upon delivery of the car, customer was not happy with how his OE intake manifold looked compared to the bright red intercooler piping, decided to order a Cosworth intake manifold and have it powdercoated bright red to match piping. After install, we had to retune the car, it ran richer unexpectedly, and we had to take about 8-10% fuel and the power above 3500 RPM dropped about 20-25WHP. Cosworth manifold would have made extra power if we were running a GT30R or bigger turbo along with headwork. Looks like this is not a good choice for OE or smaller bolt on turbos.

















One thing to look at is the 225WHP (300 crank HP) mark on the dyno charts. Subaru USA states car makes 305 crank HP @ 6000RPMs.

our 225WHP tests:
OE turbo + TMIC 5000RPMs
Tomei turbo + TMIC 4300RPMs
Tomei turbo + FMIC 3700RPMs
Tomei turbo + FMIC + Cossy int.manifold 4000RPMs

2009 WRX Test & Tune

We had chance to work on a 2009 WRX and the results are amazing. Subaru did a great job on this new model. Its a lot different than the 2008 version. Rated at 265HP, the new WRX is running a STi turbo. Combined with 2.5L engine, its a response monster.

Setup:
Tomei unequal-lenght header & uppipe
Invidia downpipe
Agency Power exhaust
injen intake
Perrin Top Mount i/c
HKS blowoff valve kit
Custom oil cooler
ECUflash tune
















30mph-145mph Test
We had done this setup back in January 2009 when the car had 1200 miles, now customer wants more power after putting another 2500miles on it.
We will be fabricating a GT30R turbo kit along with a custom intercooler setup. Stay tuned!
