Default Cosworth & APS FTW Dyno Flash STI @ 704 whp and rising!

My long and winding journey with Subaru has reached new ground this evening on my own STI with 704 whp on 93 octane pump gas and Aquamist meth injection.

I have to give huge props to the Cosworth Intake which I credit for getting me over the hump and into the big leauges. Lately we have been building some very strong pump gas and meth customer builds which have been making 630 - 650 whp with relative ease and they all shared the Magnus intake manifold. I have been having a huge struggle on my own STI to get similar numbers without really pushing the limits and I have been theorizing that the stock intake manifold was my weak link in my chain of performance mods.

The events of this evening have shown that the Cosworth intake is a very effective addition. My estimate is that it is worth about 80 whp on my set up with no appreciable increase in lag or delay in throttle response as compared to my same set up with the stock intake.

Here are my main power modificatons at this point

Cosworth 9.2/1 Pistons
Cosworth Rods
Balanced and polished stock crank
AEBS Sleeves
Cosworth Bearings
Cosworth HP Oil pump
Cosworth Oil Baffel
Cosworth H11 head studs
Cosworth head gaskets
GSC 272 Cams
Headway Performance ported head
Denso IKH24 plugs
P & L 1200 Fuel rail and injector kit
Buschur Double Pumper
Buschur Mini battery kit
APS TSR 70 turbo kit with 1.06 a.r turbine
APS DR725 fmic
Aquamist HFS 5 alcohol injection
Turbosmart E boost 2
AEM EMS tuned by Dyno Flash



I have been having a blast being back behind the wheel of my own fast car after so many months of the build up process. I really missed the car and its now by far the fastest Subaru I have ever driven.

I out the entire motor together myself, installed everything and tuned it myself and it took me a really long time to do it as I have been so busy with my work on customer's cars that the most I have spent is a couple of hours here and there.

I am so happy with the car just driving around the road that I am leery to head to the track and break any more half shafts. lol

I have a video to follow later.

Congrats on breaking the 700 whp mark! I think i would be terrified just standing next to something that fast. Just about 4 years in the making now, so I have to ask about your future plans with this car. You wanted a dominant street car, and have completed the task. Other than trying to put this in the 9's, any more tuning or modification in the plans?

800whp?

Honestly, its going to be a few days or weeks just to relax and enjoy this car before I do anything else to it.

Its been about 9 years since I first drove a 2002 WRX (back in 2001) and started to try and make one "real fast." How that I have one sitting ion my driveway, I have to just appreciate and enjoy the machine right now and then decide on what to do next.

For now my plan is to take some customers for test drives and share the experience of driving in this with as many people as possible.

Thanks

Hey AL , at what point do you think the stock intake becomes a limiting factor ? Basically I'm curious to know if replacing the intake at an earlier power/mod level would allow the motor to operate more efficient.

Seems that the people over at Cobb Tuning have issues with the intake on the 18G-20G sized turbos.

I would also suggest that anyone who wants to see the full potential of this unit, you will need to free up airflow, by going with a cold air or short ram intake. I am normally a very big advocate of the stock airbox, but in this case it IS a restriction. I will be retesting with an intake shortly to quantify the findings.

He's talking about the intake manifold, not the air intake.

Congrats! i've made decent power on the stock mani and throttle body and have been contemplating getting a cosworth mani, i always said it would suck to spend that kind of money and not get much gains from it.
Are you 100% sure that this mani helped you make so much more power or could it be in the new build?
Congrats again, looks like there will be quite a few 9 sec subaru around this year.
