Default Accelerated Performance's BRZ-300 Kit gets more boost thanks to EcuTek !

Event: Dyno Tune !
Location: Accelerated Performance| Toledo, OH
Ambient Temp: 80 degrees
Elevation: 790-800ft
Weather: Pretty Warm

Car: 2012 Subaru BRZ
Tuner: Visconti
Dyno Info: DynoJet 224
Peak HP at RPM: 278 @ 7200
Peak Torque at RPM: 215 @ 5500
Baseline hp/tq for a stock on same dyno: 161WHP/136WTQ
Target AFR:
Fuel: Straight 93 unleaded
Engine/Power Modifications: Stock Header, Accelerated Performance BRZ-300 Turbo Kit @ 10PSI, OMNI 4 BAR Map Sensor

Well it's been a few weeks since I first posted up the results of this turbo kit on low boost..

Last time on the dyno we ran into ecu limits preventing us from increasing the boost. Since then EcuTek has been working super hard on defining this ECU. Well their hard work paid off because now this car is taking boost like a champ!









I'll post up more info later - Have a turbo automatic to tune tomorrow so need to get ready for that!

Very nice. Do you think that's about all the boost it can take unless you lower the compression? Or is there more on the table?

I think it'll make a little more with a header and larger injections.

Port Injectors are maxed out and I dont trust the direct injection enough to increase the volume of fuel coming out of them for additional hp..

Fuel volume is not a problem at this point in time - so no boostapump

I have a few different sized injectors from Spray It Racing coming that I need to try out.

This is a good power level for this car right now.

Once I get the Per Gear Boost Control from EcuTek we can start turning up the boost - until then it'll be pointless.

I'm curious to know why these cars aren't making torque like our boxers...(wrx/legacy/fozz/etc)

Besides the obvious 2.5L reasoning...I'm talking 2L to 2L...RWD?

reminds me of the low torque from any other fwd turbo'd honda, its the reason all of those guys even with 500+whp go to a lower hp subie, the torque being so low and the traction

I have a really weak wastegate spring in the car so boost doesn't come on hard, it slowly rolls in.

If I were to put a 10PSI spring in it I think it would come on harder

Does this motor use a cam driven fuel pump? Has it been considered when increasing power? I know that on some other direct injection platforms it is a huge limitation, and is often replaced if you're going to do anything past stock or Stage 1.

So far so good with fueling.

I've increased the demand on the direct injection system a good amount - but having tuned other DI platforms i know what kinda mess could lie ahead.

This is why during WOT I mostly use Port Injection - but nothing to date has given me any concerns on this DI system - works SURPRISING well. I think its fair to assume Toyota & Subaru didn't ask for Mazda's help lol

Awesome job guys! Graph looks really nice.

Does the BRZ come from the factory with port injection and direct injection? Or did you add the port injection for the turbo kit?

Wierd...wonder what the reasoning is behind that. Havn't tuned or worked with many direct injection cars.

To be honest the way it's setup from the factory doesn't make 100% sense to me.

During WOT in the midrange its only using Direct

It always is.

I found some good info in our tech manuals and online that kinda filled me in. Interesting way for them to get around some of the DI driveability problems...

Either way..sorry to jack. The turbo BRZ is da sex.
