Default Stage 2 06 STi - 294WHP / 320WTQ tuned by Harman Motive

Well I just got back from Harman Motive for my protune, and I think it turned out really good!



294WHP / 320 WTQ on pump 95 @ 21PSI on a Mustang dyno!

Mods:
Invidia G200 Cat-back
Invidia High-Flow Catted Downpipe
Cobb AccessPort
Cobb Turbo Heat Shield
SPT Intake w/ Heat Shield
NGK Iridium 1-Step Colder Spark Plugs
Walbro 255LPH Fuel Pump
Perrin LW Crank Pulley
Perrin Radiator Shroud
STi Radiator Cap
Amsoil 5W-30 Fully Synthetic Motor Oil

Tuner said it'd probably be at 320whp/350wtq on their old Dynojet, we were both very surprised at the numbers for just a stage 2 06. Tuner was convinced I had blown the turbo and a dealership replaced it with an 07 turbo by accident. It's hard to see in the picture but the curve is very smooth and it holds power unusally well for a stage 2 STi.

Initially impressions: on the freeway, 4th, 5th, and even 6th gear pull like a frieght train. It felt like a completely different car. Once I got back to Vegas it started to calm down due to the heat and altitude, but in SoCal it felt like a friggen monster 1st through 3rd gear I don't really feel a difference in power or boost, but at least it should be running healthier. Overall I'm real happy with the power delivery and consistency.

294 whp 320 TQ on 95
277 whp 29X Tq on 91 pee water

Average STi stage 2 is 260-265 whp on 91 @ like 5500
and 280ish TQ

His car is excessive becauseit makes over 270 whp from 5800+
where usually it drops like a ROCK

This car amazed me, Period.

Marcus if you want to run some logs out there in vegass i can tweak the map or you a bit :-p


oh and the new dyno reads 15% LOWER THAN THE DYNOJET

351 whp car here was 408 on the DJ
470 whp was 540
etc etc etc

btw to further the Mustang VS dynojet (why they are high) i figured i would post this lil snippet of info from the Hot rod article "The Story Behind the Dynojet Chassis Dyno "

Quote:
One of the biggest headaches of Dynojet's go-it-alone chassis-dyno project was figuring out how to assign meaningful power numbers in the face of unknown inertia from the moving parts of the hundreds or thousands of engine, drivetrain, and tire combinations. Wrestling to fully understand inertia and powertrain losses, Dobeck and his team quickly realized that the standard physics formula of weight, time, and distance for converting acceleration into horsepower simply didn't work-the derived number was always lower than accepted numbers. They poured on resources and burned up time and money investigating it, but no matter what they did, the math never added up.
Dynojet's final number-fudge was arbitrarily based on a number from the most powerful road-going motorcycle of the time, the '85 1,200cc Yamaha VMax. The VMax had 145 advertised factory horsepower, which was far above the raw 90hp number spit out by the formula. Meanwhile, existing aftermarket torque-cell engine dynamometers delivered numbers that clustered around 120. Always a pragmatist, Dobeck finally ordered his Chief Engineer to doctor the math so that the Dynojet 100 measured 120 hp for a stock VMax. And that was that: For once and forever, the power of everything else in the world would be relative to the '85 Yamaha VMax and a fudged imaginary number.
Dobeck's engineering staff was dismayed by the decision, but the Dynojet 100 exclusively measured surplus power available to accelerate the vehicle's mass-no more, no less-and that was true even if the modification was a low-inertia flywheel or lightweight wheels. As long as the inertial dyno's numbers were repeatable, the critical question (did a particular modification make the engine accelerate faster or slower?) would be answered correctly.

not on a mustang, i see dynoflash tuned so it was either on ICS's MOON dyno (reads as high as the) OR the manipulated DD @ THE SHOP

Whoops, I wasn't even looking closely, yeah, I had the hp and tq numbers flipped.

I'm a dummy.

Also, another member said he put down 238 WHP and 232 WTQ on the same dyno in a bone stock 06 STi...almost 100WTQ less than what I put down

What does a stock STI make on that Dyno? Thats the question. You can make a Mustang read anything you want it to.

That sure is a smooth looking curve! Good job John!

Nice looking curve.
Do you use the weather correction factor on the Mustang? If so, do you have a weather station or just enter values manually? Also, why such a high smoothing factor of 70? I know the newer units are much more sensitive but 70 is pretty high even for that.

Thanks

HOLY CRAP! A smoothing value of 70 guys! I did not notice that. No wonder it so damn smooth!

238whp for a stock STI? Man thats dynojet type numbers. The one in vegas I tune on is 188 to 200whp for a stock car and the one in town here is 200. Still thats good gains man! Its just nice to know what the delta is. Good job on the tune!

for some reason the eddy on this dyno produces a wave like pattern on some cars. I use the tach and not the roller speed as well which induces some weird ness.
Here is his chart @ 25 smoothing

i know
the 07 wrx we did dynoed EXACTLY the same as buschurs (low)
so idk wtf is up.

The TSR 70 dynoed @ 351 here and 408 on the dynojet
and a car that i did 540 on the dj ran 470 here

The newer mustang units are certainly much more sensitive and will show much more detail in the graph. I'm not sure if this is a software or hardware revision, but that's what I've seen. As a result the general smoothing factor value range is much wider than in the older units. I've also found that some cars produce more noise than others but I always used the roller speed calibration instead of the RPM pickup. Maybe try giving that a shot?

Thanks

I guess I shouldn't mention the 304/358 I got on my 05 STI stage 2 with 92 octane and 18 psi on a mustang dyno :-D

Well I've seen several stock STI's put down 260-270whp on certain dynojets, so that would be approximately 15% higher than the one you recorded

same car
same tunes
different dynos (both ours)
same weather (its pretty much SAE here every day )

21psi 06 sti pump gas
logged both no knock on either.
The maf housing causes a bit of V fluctuation
hence the wavies

What's interesting is the average stock STi dyno (back in December '06) on Harman Motive's old Dynojet was 240 whp/250 wtq.

Right
THIS PARTICULAR Stock Sti (238 whp 06 sti)
was WAY out of line on this dyno
the 03 wrx , 07 wrx and 08wrx were right along with buschur and PDX's numbers......

stupid dynos
