Short and sweet, '04 STi ran 189.092 mph at the Texas Mile, a new Texas Mile mark for Subaru. Another run at the Texas Mile this weekend and the car exceeded my expectations once again. Hats off to Chris and Brad at EngineLogics for their fine work under a very, very tight schedule; they did excellent work as usual and provided a safe tune that did what we wanted. Big thanks to Full Race for pulling the kit together on short notice - fitment was excellent and it performed very well, and still has more room. A little background on the car and history at the Texas Mile:

March 2007 - 156 mph
stock engine / Perrin 35R/Perrin FMIC/225x45x17 tires/93 Octane / 24psi
October 2007 - 170 mph
stock engine / Perrin 35R/Perrin FMIC/225x45x17 tires/112 Octane Race Gas/rear diffuser/28psi
March 2008 - 169 mph / wingless and same set up as October 2007 Mile
March 2009 - 182 mph / wingless / EngineLogics Engine / Perrin 35R / C16 /27psi/

Changes for the October 2009 Mile:
Full Race GT4088R with 1.06a/r (wrapped header and UP)
-10 Fuel Line from the surge
2.5Qrt Surge Tank (mounted behind the drivers fog cover)
Fuel Lab 105gph fuel pump
Home made aluminum front air dam
Hankook 225x45x18 tires
Modified passenger fog cover with coolant duct to turbo

Impressive stuff! Looked very uneventful..Very stable... At first,I was curious as to why I could not hear the usual siren sound that comes at speed..I then realized that the mirrors had been pulled.

I wonder though... would it have been legal to have aero mods such as the wheel covers on this car?

blowbyu24 · 10-18-2009, 10:33 PM

awesome mph...glad to see you joined the 4088 club!!!

No wheel covers allowed, but I wish they were because the wheel spokes do add drag.

The car was stable after I changed the suspension from firm to soft and dropped the air pressure from 45lbs to 38lbs. One of the other STi owners called the US AST distributor and they told us to turn them to soft so the springs would load properly. Friday's runs were a little scary...nasty cross wind that made the car float at about the 1/2 mile mark and when you hit the brakes. Needless to say after a few trips down the track under those conditions I shut it down for the day.

Awesome! Congrats!

Thanks...I followed your advice and went with the 40R vs. the 42. While it doesn't doesn't help much to launch the car I used the launch control to help warm up the clutch after this run on Saturday...

YouTube - October 2009 TX Mile Clutch Slip

Clutch slipped at peak torque. The rev limiter is set at 8k. Gear shift by RPM for the 189 run were as follows:

2nd/3rd - 7200
4th/5th/6th - 7800

blowbyu24 · 10-18-2009, 10:56 PM

yeah you can hear that...well glad to hear the LC help fix the problem

did you notice much difference from 225/17 to 225/18?? pertaining to gearing length and mph?? i was thinking about going with a taller tire as well since our gearing lacks for top end runs

Its hard to measure, but I felt it couldn't hurt. I was pretty much stuck with the 18's if I wanted to run the front air dam...it would have rubbed with the 17's when I hit the brakes.

Ah gotcha...

Any video footage of those runs with the crosswind??

I must admit,there is something surreal to me about a Subaru clocking 190mph! I wonder what the speedometer needle looked like

I'll check the tapes. I video'd every run so I should have them. You can see the car bunny hop down the track, it literally moved several feet and I had really pay attention, so I did look at much other than my RPMs. I use a HUD that I glance at when I hit the 1/2 mile mark to gauge where I am, the OEM speedo is buried, but we datalogged a 184 run and the laser speed traps were dead on.

There were several spinouts this weekend and this morning a beautiful '56 P/U rolled several times after he lost it right around the 1/2 mile mark ...http://www.dallasclassicchevy.com/Fe...r0810Raley.htm. This picture was taken by another NASIOC member (RallyGuy2K)...

i guess every little bit helps

the launch sucked!!! but the power and after was so bad ass... raise the 2 step and you'll be out brother

It isn't a drag race so trust me when I say that there is no need to hard launch the car. The only reason I used the launch control was to heat up the clutch.

IIRC this was a 182 run...a little loose after 1/2 mile.

189.092... there is a big difference between that and 190.

jamal · 10-19-2009, 06:57 AM

wow that's fast.

I wonder how much narrower, higher offset wheels, blocking off your bumper air inlet, and more lowering would gain. Also, can you flat-bottom the car?

rxw · 10-19-2009, 09:05 AM

Interested in the Full-Race 40r kit.... got a dyno graph?

H.K. Phooey · 10-19-2009, 10:24 AM

Well done Bill, I started a thread in the motorsports section.

whoops...

I do and will add them to the first post tonight.

bgod · 10-19-2009, 11:34 AM

Simply awesome. I've done a closed course run on the salt flats with a small group and would love to do this one day.

But it's seriously scarey how unstable these cars can feel at speed.

Any ideas of maybe how to keep it more planted? Any more aero upgrades in the future?
