Default Anyone know of a dyno on the 2009???

I know they are just hitting dealers, but knowing how some people dyno on the same tank the dealer gave them I figured there might be a dyno floating arond somewhere?

I have searched google, some of the aftermarket sites (perrin), the forums and youtube but dont see anything yet.

I was impressed with the 08's numbers (210/240) considering they rated flywheel hp as 225...

Hopefully the same holds true with the new 265 hp rating! Using the same ricer math that would be 240-245whp which is stock sti territory

STis put down approximately 215 to the wheels on a mustang or dyno dynamics what kind of dyno are your numbers coming from?

I am coming from my svt focus, bolted it puts down 155whp (170 oem crank). These little n/a engines dont respond well to mods since they flow so well from the factory. with all my mods I only netted about a 15 whp gain!

So moving to either an ms3 or an 09 wrx I will be adding close to 100whp and almost doubling my wtq (130!).

My svtf only weighs 2800 where both wrx/ms3 weigh a good bit more (500lbs or so) but that little snail under the hood should cover that up pretty quick.

I'm not sure where the power gains in '09 are coming from, but the block itself has been pretty similar since the '04 sti. So regardless of how much power it puts down, if you're planning to mod it that data is irrelavent - you can be pretty sure of the approx power it'll make given X mods based on previously documented setups.

Thew 41 hp comes from a bigger turbo (supposedly STI spec...or close to it). Hopefully with some tuning and an intake/exhaust of some sort it puts down pretty good numbers.

I am really excited to see the stock numbers vs the 08 wrx and sti.

Perrin did the base runs.

http://forums.nasioc.com/forums/show....php?t=1425666

Here is the paragraph where he explains his findings on the base run.

Our base runs we did showed a peak of 210WHP and 245ft-lbs of tq. I thought this seemed a little high. High enough i had to go back on the internet to see what Subaru rated the 08 WRX in HP and TQ. No its the same, 224HP and 226ft-lbs at 2800 RPM. Did Subaru under rate this car? Given the WHP and TQ we saw, if you compare it to our STI's base readings, it makes the STI's 245WHP and 275ft-lbs not look so good. With all the dyno numbers we have seen on stock STIs (rated at 300HP) The 245WHP range has been exceptable as equaling 300 engine HP. So if 240-ish means 300 engine HP, what does, 210WHP mean in engine HP?? Surely not 224HP!

Even if their dyno's read high you can compare the two cars to each other.
Wrx = 215/245
STI = 245/275

So the base line of this 08 wrx is creeping into STI territory. This is why I want to see the 09 graph. the 09 is rated at 265 hp or so, so as long as it dyno's relative to how the sti/08wrx are showing it should be close to STI numbers

maybe subaru finally put out the actual crank hp that matches the 215whp above

subaru is smart and wants to keep the average uneducated STi owner in the dark about what the wrx makes....

it trapped 101mph in the tests so far...the sti traps 102-103mph....

but the wrx also weighs 300 lbs less and has one less shift....so the power is up there, but its not gonna dyno more than the STi...due to its weight and shifting disadvantage the STi has to have a higher power/weight and since it weighs 350 lbs more we know it has to make more power

with the sti you're not paying for the power, you're paying for the tranny, dccd, brakes, fender flares, etc.

the power is the cheap part, the vf39 in mass quantities cost what $300 compared to a $9000 tranny......$3000 brakes....

you can buy a $50 mbc for either car and make 60-70 ft*lbs of tq more in about 5 minutes

Phantom: that was my theory about a month ago as well. That subaru just upped the flywheel oem numbers to match their whp numbers. BUT there is a new larger turbo in the 09 than the 08 (some are saying its the sti turbo...but its bigger nonetheless).

Hopefully even if the boost in whp is slight, it will still be higher than the 215/245 perrin baselined. Even if it shows 230/260, thats +15whp/15wtq which puts it directly in between the 08 wrx and the sti's numbers.

doesnt matter...

bottom line is the wrx trapped 101mph and weighs 350 lbs less, the sti traps 103mph and weighs 350 lbs more. therefore the sti is still making more power.....how much, who knows...but its still making more power.

Where are you getting those numbers from... or are you comparing multiple magazine times?

According to Road and Track...

09 WRX - 13.8 @ 101 mph (84 degrees) :: http://www.roadandtrack.com/assets/d...risonchart.pdf
08 STi - 13.6 @ 98 mph (66 degrees) :: http://www.roadandtrack.com/assets/d...Vwrx_chart.pdf

And the test weight of the WRX was only 140 pounds less than the STI.

The STI was even tested in cooler less humid weather. I have a feeling the power difference will be less than you believe.

quite a bit more for 350lbs more weight
I drove both, the 09 last wednesday and it feels like he car has more guts up top where as the 08 fell flat
the "new" turbo must hold boost better, but it's still not as fast as the 08 STI I drove when I test drove the 08 wrx
all three were hands down felt slower than my 07
with mods, same as makes no difference who ever has a deeper pocket will make more power

dont quote road and track and C&D..they use the freaking "hypothetical" method with correction factor for crying out loud.
Motor trend is one of the few big name magazines left that tests the cars for what they actually run, not the "best possible"
also edmunds is a good source for 1/4mile. 08 STi - 13.3

i was using common traps for every stock sti since 2004. 102-104mph and then the 101mph trap for the 2009 wrx from whatever magazine that was....

even if they both trap 104mph it still means the sti is making more power cause of the weight and extra shift in the quarter

the 07s stay in 4th because of teh longer gearing
I'm pretty pretty sure the 08 STis re the same

and the 07's werent any faster stock or modified with that gearing....the power falls off above 6000rpm so most drag racers actually went faster by shifting into 5th anyway

Truth.
The sad fact is usa, we just get screwed in the ass in terms of head flow .. Just give us the damn JDM motor.

^^ subaru gave us heads that are effective for the engine/power....

they dont need to be monster ported on the 2.5L to make the 305hp.....however its probably a necessity on the 2L to make the same power.

if subaru gave us better heads they'd probably lower the boost and/or use a smaller turbo

Is it still a mitsu. turbo in the 09 WRX or did they go to an exclusive VF series of some sort?

And the power difference between a WRX and an STI is one of the many differences between the cars. Anyone that knows anything about modding a subaru should know a WRX can easily creep into STI territory power wise with $1500 invested into the car. I went from a WRX to an STI not because it's faster (my old WRX was much faster than my stg. 2 STI) but because it is a much better platform to make serious power with. The transmission alone is worth the price difference! Then you consider the stronger engine internals, DCCD, forged aluminum suspension parts, HID's, BBS's, nicer interior...the list goes on.

I will say from a business aspect, giving the WRX a 40hp bump in power and keeping the STI around the 300 mark will hurt STI sales. The average buyer cares about stock hp and not the possibilities of aftermarket modifications. Making this gap closer/smaller is going to make it tougher to justify the $8-10k price difference when it comes time to making a buying decision. I think Subaru needs to drop these IHI VF turbos and use an 18G or the similar on the STI.
