Throw Down! MS3 260whp 300wtq

[ZooZoom]

no joking.

went to a Dyno Day with some buddies from my Subaru period. mostly Legacies and WRX/STIs running. I tossed up my essentially stock Speed3 about midday and, needless to say, it got a boat load of attention!

performance mods only ETS 3.25" TMIC and K&N panel filter
stock intake box, stock exhaust
other mods are brakes/suspension related only

I can tell you a bunch of Suby guys are talking about the Speed3 right now.....and probably thinking about going to a Mazda dealership for a test drive!

ZOOM ZOOM!!! (dance)

 

[uncletime]

with just the tmic upgrade huh? wow not bad. what gear did they run it in. i know there was a discussion about which one it should be run in.

 

[ebmp5]

DAYUM!!! that is tight.

 

[Ferdball]

I don't know how you get so much power. I remember you pulled 5HP more than us even with CAI's on.

 

[ZooZoom]

I honestly believe it comes from the fact that I run my Speed3 hard. I regularly hit 120-140mph. virtually daily (on a closed road course, of course).

I've taken it to the track 3 times in 3 months. I gotta believe that the ECU adapts to the driving style.

Plus I just turned 16k miles on the odometer. So the engine is very well broken in.

I need access to you fictitious road course!

hate to rain on your parade but i think that dyno might be fcked up...


unless you got the numbers of a stock STi down, or at least the ones of one of your friend's with mods listed so we can verify/compare.

dont mean to sound like a jerk, but those are big numbers for the mods you got. just curious.

that's a ballsy claim from the other side of the country, my friend.

the guy from Yimi Motorsports said he'd post up the dyno plots on Monday. mine is a color scan of the print they gave me.

to give you some idea that this dyno is no "queen", a Subaru dealer brought a 2008 Legacy 3.0R that recent passed 500 miles driving (so the engine was reasonably broken-in).

he threw it up on the dyno and got a measly 172 whp / 154 wtq. that's from a car that claims 250/250.

my car ran immediately after that.

I do recall my buddy Merv with a 4WD Legacy GT Wagon running a 18G turbo setup with a Perrin TMIC put down 330 whp / 335 wtq

 

[laloosh]

I find it odd that your car has a perfect a/f ratio throughout the band

What was the temperature and humidity? I did my pulls at 94 degrees with 27 humidity but even with the correcting factor, I'm not getting anywhere near that sort of power.

Did they have some sort of special cooling assembly for the TMIC? On the stock TMIC, with a small fan we were seeing huge powerlosses between pulls. This shop was geared towards cooling FMICs, but even so I would have expected more loss even with a custom assembly to show on yours if they were run back to back.

What were their correction factors set at? Is this Dyno "tuned" in any other ways?

Your powerband looks ridiculous compared to my own.

Here's my first pull from earlier this month (much more in line with what I've seen people pulling):

I agree..Something is not right.Those numbers are a bit to high.300lb. torque on a stock engine isnt normal for our cars.That dyno is showing inflated #s or there something that was done on this dyno run that we dont know about.

 

[speedi3]

What does the SAE smoothing mean? Yours says 5. Mine said 1. the one above says 3.

I have a few more mods... Drive on the interstate regularly at 120ish... my A/f was the pits at 4k. I hope its true but seems off in comparison to other dynos...

 

[ophten]

What does the SAE smoothing mean? Yours says 5. Mine said 1. the one above says 3.

Its just a setting in the Dynojet software which lets you smooth out your curves a bit after selecting your correction factor (SAE, DIN, EEC, STD, JIS).

The smoothing shouldn't have a large impact on your numbers, for instance with smoothing set at 0 on mine I get max power of 222.81 and torque of 230.75 compared to a smoothing of 5 with 221.87 and 230.47. The smoothing is just used to smooth over your peaks and valleys.

I wonder what his uncorrected numbers were? Mine were 215/223

So driving really fast will help build more hp... even if it isn't true, you don't have to tell me twice. I love how even though the results are posted people still call BS. Even if some tricks were involved I'm impressed and am ordering a K&N filter NOW!

I can ask for the uncorrected dyno plot on Monday.

To give you some idea of the "honesty" of this dyno, my 3rd & 4th pulls dropped noticably. I lost 20 hp & almost 30 tq due to heat soak on the dyno even with the bigger TMIC. But that shop had only two small fans to move air over the car. And I chose to do it with the hood closed trying to blow the fan air into the grill. But it wasn't close to real world conditions of traveling well over 100 mph.

I don't want to argue about it. Trust it, don't trust it. I don't care.

I do know that my Speed3 is running sharp and it kicked ass on several RX-7s and RX-8s at the Mazdafest two weeks ago. I've got the vids to prove it.

 

[ophten]

Not trying to be argumentative, I'm just trying to find out why my speed3 is so craptacular in comparison ;-)

You should ask your shop to give you the DRFs. You can download a demo version of WinPEP7 and change formatting/scale/unit measurements and a bunch of other options. It'll allow you to post your results from multiple upgrades side by side regardless of when they were taken. I'm actually quite surprised they didn't just email you your DRFs as it was, they're quite small.

I'd be interested to know if they've setup anything special with their dyno system, I haven't a clue how one is tuned so I don't know what options are even available. If so, I'd like to compare those tuning options to Protech Performance here in Austin to see if that's what's causing the descrepancy.

the guy that works at Yimi and ran the dyno yesterday says he thinks only one other car all day was stock......a EVO IX SE. the dyno plots are on the computer at the shop so he can't e-mail me anything today. he's going to give me an uncorrected plot for my Speed3 but says that the Dynojet doesn't have many "fudge factors" that can be reset like some other dyno brands (Mustang, DynoDynamics etc.) and the SAE correction is a preset compensation for ambient conditions (temp/humidity) and elevation. The shop is at 1,000 ft. sea level. So he said that factor is low, maybe 10 hp.

He didn't recall the full numbers for the stock EVO except it put down around 250 whp.

I can't fully explain why my Speed3 seems to have a "hot" ECU. My AFRs were much better this time around compared to when I dyno'd it about a month after buying it. I do run 100 octane race gas but only on track days. Its been 2 weeks and at least 3 tanks full of Cal 91 octane pump gas since then. Of course, I only had Shell 91 pump gas in the car yesterday.

all that I know is that I'm a very happy camper and my Speed3 earned a heck of a lot of respect from my Suby pals yesterday! (cabpatch)

 

[ZooZoom]

to give you some comparisons, here's what I did see/do know from yesterday running on the same day/dyno obviously:

05 Legacy GT Wagon, 5MT (modded with 18G turbo and Perrin TMIC, AP Protuned) 330 whp / 335 wtq
05 Legacy GT Sedan, 5MT (catless UP, catted dp, stock turbo, AP Stg 1 map) 230 whp / 240 wtq
05 Legacy GT Sedan, 5MT (MR headers/up, catless dp, cbe, stock turbo, AP Stg 2 map) 260 whp / 315 wtq
08 Legacy 3.0R Auto (only 500 miles on odometer) 170 whp / 165 wtq yeah it got laughed at pretty badly
97 Volvo 940Turbo (running open exhaust disconnected at the DP, not sure of mods) 190 whp / 200 wtq

Here's a quote from Paul who ran Yimi's dyno on Saturday, "A stock STi puts down anywhere from 245-255 whp our dyno. A stock Evo 9 ran yesterday and put down about 250whp. In very similar heat a couple of days ago, marcocb8's stage 2 LGT (catted with stock catback) did 240whp on the Cobb map and 255whp on a custom Protuned map. A bone-stock 05 LGT is around 210 whp."

 

[Karma_hunden]

hm, interesting. If I may add, a stock EVO dynos 225-235whp (up to 245 being possible being one of those factory freaks..). I say that because I used to work for an STI/EVO workshop. Those were the numbers they put down. So that dyno must be 15 digits off the charts. So you should have what ya have minus 15 as a estimate, which is quite impressive and still kick ass. I bet you will give those subies/evos a run for their money. Congrats nonetheless!

there's only one way to find out. Go to the track
