2011 WRX Stock vs. Stage 1

xluben · 11-19-2010, 11:26 AM

Got a fairly conservative "Stage 1" road tune on my 2011 WRX. Baseline and after tune information is included. Only changes to the car are an SPT Cat Back Exhaust and the 16" steelies and winter tires. RomRaider log was used to create the dyno plot using Virtual Dyno set for the DynoJet calibration (which the Virtual Dyno developers have calibrated the software to). Numbers look about right for a DynoJet. I'm very happy with how the tune turned out. Much smoother and pulls noticeably hard through the low/mid range and up to the top end. Torque increase is very nice

Feel free to discuss!

Very nice. Can't wait to get a tune for mine, but I'm going to have to

irish44j · 11-19-2010, 01:52 PM

Nice numbers. Your stock numbers are almost identical to my 09 stock (also with SPT catback), which was done on an in-shop dynojet.

but prepare for everyone to come in here and start saying how bogus those stock numbers are, because they always do, no matter how many stock 09+ wtx dynos we post up here with almost identical numbers, lol....

Rocko15 · 11-19-2010, 01:55 PM

Congrats on some great numbers. I just went stage two last night, can't wait to get some miles on the tune and really rip on it!

I was hesitant, but it was totally worth it. Nuke (tuner) was great!

That's good to know. I think the software is calibrated really well, seems to be very accurate compared to real life results on a dyno.

The program can also be set for Mustang dyno's. If you change it to that setting the numbers (both baseline and stage 1) are very, very close (within a couple hp) to the numbers that COBB shows on their dyno plots.

I'm looking forward to getting a downpipe eventually. Stage 2 sounds like a good place to aim for. I probably won't go anywhere past that, though.

cdoliver · 11-19-2010, 02:06 PM

The Tq increase looks right on target. The Hp increase is a little low, probably due to the 91 octane. Most stage 1 increases are around 30 hp and 40 tq give or take. Good job none the less! What was the target AFR? and how does it look now? Most stock afr's look like crap...

He said it was running rich, but I don't know enough about tuning for any of the numbers to mean anything to me. I did tell him to set it on the conservative side, I'd rather not have any issues down the line, and the fact that it was a 91 octane tune lowers the power even a little more. I'm happy with the results!

2barsti · 11-19-2010, 02:19 PM

Great #'s! Thumbs up for Nuke. He also tuned my 04' sti on e85.

I kept the timing pretty conservative being that this is a new car and his daily driver. The AFR is kept around 10.8-10.7

A few more hp can still be made but he is happy with it, so we'll leave it at that.

Thanks Nuke. Really enjoying the car!

Thats a nice increase over stock, especially for a conservative tune. Man I wish I had a tuner close by.......

We can get you tuned nicely remotely

They, like a few others, can get your mod list and create an ecu ROM that they email to you. You'd have to flash it, do some WOT pulls, and send the logs back for them to make some minor tweaks and send you a revised ROM. Not quite as good as having them in the car doing the work, but it works.

thats not really true.

i cant magically change any different parameters if im sitting in your passenger seat. there is literally no difference in doing the pull with me in the passenger seat.....or emailing me the log 5 minutes later.

the only thing being in person helps with is trouble shooting problems.

nuke, was this in OS?

But then I wouldn't get to spend the afternoon driving around with Nuke

Ron, this was with both Ecuflash & RR

I take it these figures are at the flywheel?

These are wheel horsepower numbers, calibrated for a Dynojet.

Here's the Mustang calibrated numbers:

Car: 2011 WRX 5 Door
Tuner: Nuke
Dyno Info: Virtual Dyno - Mustang Calibration
Baseline:
Peak HP at RPM: 230hp@6,000rpm
Peak Torque at RPM: 248hp@3,200rpm
Stage 1:
Peak HP at RPM: 240hp@6,000rpm
Peak Torque at RPM: 283hp@3,500rpm

Phatron · 11-22-2010, 11:37 AM

well....they are whp, BUT the stock car was making 265whp.....which is equivalent to the factory 265 CRANK hp rating.......so you're pretty much walking a line of semantics.

It was taken on the road and is a whp reading....but one can also make the case that this software gives a CRANK hp reading based on the 265 whp equaling the factory 265 crank hp rating.

ScoobyDoo69er · 11-22-2010, 11:43 AM

Sorry, you're saying a factory WRX has around 330bhp at the flywheel then? The factory car makes 265bhp at the flywheel. It definitely does not make 265 at the wheels.. 275 at the flywheel sounds right for a stage 1.

For the original plot, the program was calibrated to read similarly to a Dynojet.

If lower numbers will make you happy, look at the Mustang calibrated plot I just posted.

230whp / 248wtq (stock at the wheels)

These numbers are right on what COBB and others have posted with Mustang dyno's. Assuming 20% loss that is:

288bhp / 310btq (stock at the crank)

Which is well over the manufacturer rating. I know that could be argued for days, but I believe the WRX is highly under-rated. Presumably to keep STI's selling. If you compare the acceleration times between the WRX and STI, it isn't that hard to believe that the power would be similar.

Assuming you can agree with the Mustang calibrated numbers, then all it comes down to is the software calibration for the Dynojet. The 14% difference is well within the range people see when comparing the two actual dyno's, and even a post in this thread claimed the Dynojet numbers looked like his (from a real dyno):

http://forums.nasioc.com/forums/show...6#post32506536

So, if you're asking whether or not I think it could read 264whp/285wtq on some Dynojet's, then yes, I do think so. And if you really want to calculate that back to numbers at the crank, then I do agree with your 330bhp/356btq calculation.

But the point really isn't the number. The point is the plot. Nuke gained 30+ ft-lb's of torque from 3k to 5k rpm's, and up to nearly a 50 ft-lb increase at some points. And if you ignore the hump near the peak of the stock hp curve, the tune added around 20hp from 3k rpm's on up. Feels good to my butt-dyno.

#'s on a dyno r all going to b different due to different dyno's, opperators, and conditions. Glad u like ur tune and thanks for sharing. Good increase for a conservative tune

Yeah, it's really just a calibration factor that needs to be applied in order to compare. That is what the creators of the Virtual Dyno software have done. Compared real dyno runs to logs calculated with the software, and then applied a correction factor (Cf) in order to get the numbers to read how they should on that brand of dyno.

Virtual dyno also offers the ability to "calibrate" the dyno to your local dyno by entering a custom Cf value. I found a baseline run from an 09 WRX that was done on a local Dynojet dyno. It came in right between the Dynojet and Mustang numbers that the Virtual Dyno software gave me:

Quote:

Mustang (Cf=0.95)
230hp / 248ft-lbs

Quote:

Originally Posted by Local 09 WRX, Baseline, Local Dyno Shop:

Dynojet
241hp / 258ft-lbs

Working out the numbers I come out to a 1.00 correction factor in order to get my hp to read the same as the local dyno. If I enter 1.00 into Virtual Dyno it gives me the following:

Quote:

Originally Posted by My 11 WRX, Baseline, Virtual Dyno:

Custom (Cf=1.00)
242hp / 261ft-lbs

Obviously the hp number is going to be very similar, that is what I calculated the correction factor based on (the 1hp difference is due to rounding errors, past 2 decimals). The surprising/good thing to see is that the torque is only 3ft-lbs off from the local dyno reading. This gives me pretty good confidence that the overall readings that the Virtual Dyno gave me will be close to the local dyno, as long as I set the Cf=1.00
