Micah was speaking about the increased downforce from the aero, which helps traction.

I'm a f'n old Tanzio Nuvolari, but Texan instead of Italian. I had several racing licenses in my 20's and (now), have two years of track time in NE with my STis. My car is well-prepped. I have turned fairly competitive times at Watkins Glen and Lime Rock, just doin' track time. I tried to do a TT with NASA at Summit Point when I broke pistons on my stock bottom end.
I built a new motor, which I mentioned and have been running without issue. Now, with new confidence, I am building an "Alpha" motor for the car.
I expect 450-475 WHP with this new build. The car is setup to handle it.
I did fine at NHMS when I ran 28 PSI accidentally! Boy was I passing Bimmers! I'm just out to play and have fun passing GT3's.

Just ordered the BW EFR 8374 with .92 A/R. Also ordered the high boost WG cannister. Thanks to Matty_STi for the heads-up and thanks to everyone for their input!
You can see what I have done at http://2008subarutrack.shutterfly.com/
faeflora: You've got a great imagination.
woooo

I look forward to seeing results from your fun with the 8374!!

Matt

Which is what the OP will have if he chooses this turbo for road racing. Let's see if this project gets off the ground much less comes to any sort of fruition.

OP, if you do some research on this site, you'll see that giant ass turbo is far better suited to drag racing on a 2.5L Subaru engine. Even the old GT35 would do 500-600 whp wth a good broad power band all day long. Spend some hours reading here and IWSTI and educate yourself to what really works.

Yes and amen. Thanks Matty_STi for the support. I guess I should have expected criticism when I used "crazy" in the title of my thread.
I have found that the forums can be a little harsh on occasion. You frequently get crucified for not having done your homework, yet people don't bother to read all that has been said in your thread before casting stony comments. I do read a lot and am taking it in and also experiencing it all by doing my own work; and making mistakes.
Did anyone bother to look at my photo journal on Shutterfly?
So, I'm not a noob, I read on NASIOC and IWSTI all the time and have learned a lot on the forums.

I also know what it is like to have a turbo boost come on in a FWD and spin the tires and try and toss you into the ditch from torque-steer. I also had a twin-turbo RX7-R1 when they first came out and I won a lot of autocrosses with it. However, it was leased so I drove it hard, but never touched it.
Like I said, I appreciate all the good advice.

This is my build (parts are coming in):
Borg Warner EFR 8374, .92 A/R turbine side, high pressure boost controller cannister #9180
I'm reversing a N/A impreza intake (has no TGVs to delete). I will port and CC the w-25 heads, run Supertech +1mm valves and Kelford 272 cams and GSC 5043 beehive springs with Ti retainers.
ARP studs
12mm JDM oil pump
ID 2000 injectors
Boomba fuel rails-off other motor
KS 73mm or 83mm CAI. Not doing blow-through.
Fully coated CP stock compression pistons
Wosser H beam rods (weighing 399 grams each). Balanced crank.
Tomioka timing belt guide
Act 11 pound Prolite flywheel #600240 and Perrin crank pulley
FR pipes
Was thinking of adding a Bosch 044 to my in-tank Walbro.

if your so worried about power by not go with a cosworth intake manifold it should help alot with this big of a turbo

Awesome, so you aren't new by any means.

285 tires, yes and when you can't get C91 or A6 compounds to hook when you have downforce at 100+ mph and still snatch them free with the added traction from that downforce, it means you're making more torque than the tractive force you have

Passing GT3s comes easily. Address some of your aero package, expect to upgrade brakes and run a GTX3076R and you'll have no issues with the power goal and it'll be easier to drive as well.

The 8374 should be fine. Transient response should be great but power will be later in the powerband (yes there's a difference).

Funny, I am working on my aero. I am adding a splitter, canards and a Gurney flap on the rear.
I have upgraded brakes (floating rotors, Hawk DTC-70's, etc.), and cooling ducting.
I was at NHMS in October, with BMW CCA and on the uphill the Porsche in front of me was laying rubber all the way up the hill and I kept up without having to do that (I think). With 28 PSI boost, for the one session, I felt a little more spin. That made me addicted to the power and hence the need to build this motor.
