Howdy!

I have really enjoyed seeing all of the 2015 WRX custom tune results in here and I decided to jump in with our own after a bit of playing around with ours on the Austin R&D dyno today. While this combo of parts isn't likely to be an pre-configured OTS StageX package that is available from us, we try to do as absolutely much hardparts testing as we can to make sure we have a good understanding of the cars. It's important for us to have knowledge over how the car will react to common aftermarket upgrades. No records or anything crazy but this thing is definitely one quick WRX now!

We bolted up all of the airflow mods we have on-hand for the car and decided to see what she could do. A bit more time to continue refining the tune would have likely yielded even larger results, but I quickly "chickened out" after realizing how close we were to 350 wtq It is likely that the connecting rods will prove to be the long-term weak spot for modified FA20DIT cars, so we decided to call it an afternoon with our engine still intact for now

At this point this car is now making more a tad torque and horsepower than a Stage2+Intake 2015 STI on the very same dyno -- very impressive for a 2L with diminutive factory turbo. I am slowly beginning to really like these cars now as the uncorking process continues

Long term, this testing helped us identify some other areas of the factory ECU where we should focus our future reverse engineering (table/logic discovery) in order to provide the precise control and ease of tunability that the COBB ProTuner network demands, even as the power numbers get crazier and crazier as new mods become available over time. We can't wait to keep pushing this platform and seeing what kind of amazing results you guys achieve over time!

Thank you for your support during the DIT craze!

Cheers

Lance

Lance,
What in you opinion is the biggest restriction on the motor? TMIC? Cats/JP? Intake? TGV? Keep up the good work!

Awesome work Lance! This is Justin with the 2015 ISM WRX that you and Mike @InnovativeTuning tuned. I am going in hopefully at the end of the month for very similar mods, just waiting on TBE to arrive.

Im going in for Catless TBE and RacerX Tmic.(EDIT:Already have TGV Deletes installed). Really excited, I was wondering what your opinion is on a 3port EBCS? (Haven't asked Mike yet but will)

So weird.

I was just wondering what this combination of mods would yield.

Great work. Is that dyno a bit high reading though? Those stock numbers seem inflated if measured at the wheels.

I think we'd all be interested in a 1/4 mile time.

What would you say driving around town is like now?

What about wringing it to redline? Seems like the severe powerloss after 6400 RPM is gone.

You think that Dyno reads high? It's claiming more horsepower than the car is rated at the crank stock.

Don't mind him, he has no idea what he's talking about. Different dynos read differently and should be used as a tool. Most Mustang dynos read lower than Dynojets which are considered the industry standard (although it seems like there are more Mustang Dynos out there than Dynojet). Nice numbers, about in line with what I figured you see with all available bolt-ons. Would love to see what it traps.

We have a "sound check" video that is about to be released for our new CBE that gives you a taste of how the exhaust looks and sounds

J-pipe. The others all help but they are a smaller factor.

Hello Justin! Nice to hear from you again. A 3-port is likely to be beneficial to the platform, but we haven't specifically tried using one yet. It requires some new engineering/design effort so we have plans to work on a prototype testing piece soon.

The car feels good on the street and has a very "full" powerband. The rev limiter is set to 6900 RPM and it still feels nice and peppy up top.

^^^ this. The Austin dyno does indeed tend to report somewhat high power levels, but it's really not important to what we do. We focus on the dyno as a tuning tool and also try to display percentage gains wherever possible (so as to prevent people from getting hung up on the actual numbers).

Thanks to all for the kind words and interest!

Cheers

Lance

You're right not a clue. Never said dynos don't read differently, all I said was that their particular dyno reads high as it was reading higher whp then stock advertised crank hp. Impressive gains nonetheless, can't wait to see cobb j-pipe and intake.

Not to mention their "stock" only has the AP removed if I read correctly, so the bolt-ons are still installed for run 2; is that correct?

Looks like it's out:


And looks like the j-pipe is on the cobb site now as well.
