Or would you feel better with a statement more along the lines of "makes much more power and spools the same as the VF"?

Would a couple plots tuned before on the VF, and after on the GTX3067, be enough to convince you?

i dont believe Perrin makes a 3" inlet for this model. Correct me if I'm wrong.
We've got a couple guys tackling this. I believe there is a smaller inlet out there (not sure if its Perrin) and then a 3" adapter to the turbo that can be used.

Maybe a 3" Perrin and just cap or extend the lines that don't fit this specific model would be a better option. (I think the only difference is the location of the vac line bungs

Perrin does make a stock size inlet for 08-14 WRX, but it's ~3" to 2.4" and 3"->2.4"->3" seems a bit silly.

I don't define it via max boost at X rpm (as that isn't fair if peak boost isn't the same). If I see two plots overlaid that show the 3067 making more power between 2500-3500 rpm then yes I would believe it.

But it is always nice to see a few plots that show such.

I have a turbo that spools about 150 rpm slower then a VF all things being equal. But I can easily show you a plot like this:



Now when you see that you would think it is one of the greatest turbos around. Not even at sea level, and on pump gas! Until I tell you the log was done at -8 temps. (although it was only 3rd gear, 4th would have spooled better).

I would like to see an apples to apples VF to 3067 (with Tial housing) in the same temps, same dyno, same tuner etc....

Same car on pump fuel on an OEM block with the same target boost. Any sane tuner will keep boost ~21 or so, especially when I point to the baby seat in the back and request a safe conservative tune. lol

I don't dare dip into it much blow freezing at low RPMs for fear of spinning a bearing or compressor surge, it's certainly very responsive when the temps are super low, and I'd never want to post any data under those conditions as it's a fairly rare condition and skews results. I'd personally rather skew them in the other direction and have customers that have had their expectations exceeded.

Sidenote: In the next few upcoming weeks, I'll provide a hopefully unbiased before and after going from the stocker to the GTX3067 spoolinator... though that obviously would also include TGV deletes and the larger turbo inlet as well so not perfectly apples to apples.

Install the TGV deletes and larger inlet before the dyno for the stock turbo. You shouldnt have to pull the intake manifold to install the spoolinator.

You happen to get a VD plot?

No, I sent a request earlier this week but I'll nudge Prime again.

Ok, finally got my plot but thinking maybe Prime didn't send me the final one? The spoolinator plot was done on winter wheels while the earlier plot was on my summers, which would contribute to the final number.

Hardware changes (numerous):
Prime-Built shortblock to support kit (king bearings, cp pistons, carillo pro-sa, arp l19 head studs)
IAG fuel rails, aero motive fpr
Gtx3067 spoolinator with .82ar
IAG TGV deletes
IAG air pump delete
IAG AOS swapped in for Crawford AOS
3" turbo inlet swapped in for Perrin
one-step colder plugs
mishimoto radiator
tial mv-s 38mm
cobb xle bpv
supertrapp dump tube muffler
oil went from regular to 15w50

Before: 273/300
http://flic.kr/p/pcE2bN

After: 326/341

Definitely be better without snows.

Some neat things... Spools sooner and harder, even though the pull was started a bit later. Looks like the plot stopped prematurely, but with the torque dropping slower and HP still climbing at a good rate at the end of the plot, I'd say there were still many more RPMs of power.

The most important thing is how's it feel before/after? Responsive or laggy? Wide power band, or quick and peaky?

That is a sexy smooth transition from turbo to downpipe. Would bang/10

You guys are top notch.

Although I have been saving for your headers for like a year now lol.........sigh...

Just an FYI for everyone. We are changing the Spooinator adapter to make the install MUCH easier, and offering the adapters are a stand-alone part for those that want to fab their own downpipe/exhaust.
