10.4 @ 137.46mph
Cosworth, TSR70, MZM Tune

Default Daily driven STi with a 20G - 12.4 @ 111mph

This is my daily driver with a nice conservative tune from MZM Performance (Austin, TX). I drive over 100 miles everyday back and forth to work. The car is absolutely wonderful to drive around with almost instant boost. So, I wanted to know what the car would do in the same form it's driven in every day.

The APS DR725 FMIC is probably too much intercooler for the 20G and the car actually made 20 ft/lbs more torque previously with a APS DR500 FMIC. But the DR500 was injured and is now on the permanently disabled list.

Drove 35 miles to the track, went through tech and spent about 5 minutes in the staging lanes before making a pass. Zero race prep done, nothing removed, nothing changed, no cool down, no tire pressure change etc. Launched easy, no clutch dumping or riding the clutch.

Track Conditions: 86F / 83% humidity / 7mph headwind
Car weight: 3565 with driver and half a tank of 93 octane pump gas

Code:
R/T   ...   .454
60'   ...  1.875
330   ...  5.108

1000  ... 10.296

MPH   ... 111.40
2004 STi

Modifications:
APS 65mm cold air intake
Deadbolt TD06H-20G turbo
APS DR725 front mount intercooler
Cobb catted downpipe (with 2.5 inch neckdown)
Borla Hush cat-back exhaust
NGK LFR7AIX spark plugs
MZM Performance 720cc injectors
EcuTek reflash tuned by MZM Performance (Austin, Texas)
Boost at 21psi

1 step colder that stock. Zero knock seen on the Turbo XS knocklight. Oh, and also averaging 25mpg on the daily commute!

Nice stuff.

This has me convinced that my FXT could run high 11's with the 20G I'm putting in here soon.

I think that it's also great that you ran it in full street trim.

Damn, looks like the same exact setup I'll be running... Perrin big-maf, protune, and mad dad whisper in my case though... What does a stock Sti put down on that dyno? Good numbers, should be close to 12.0 if you beat on it a little!

Certainly possible with a FXT, as it has gearing that is better suited for the 1/4 mile.

Thanks for the true street trim reference. It's a street car and it should be run as such.

If I remember correctly, a stock STi puts down 205-210whp on the MZM Performance dyno. Just remember that dyno numbers are for tuning purposes only and one dyno can't be compared to another...

It's my "work" car so there is no way I'm going to beat on it. I'm very satisfied with it.

I know one can't be compared to another... Thats why I was wondering what a stock STi put down on it so I can get an idea of how that dyno reads.... Anyhow, good numbers; I hope I can run the same when I get my turbo in

I think MZM's dyno was reading off for a bit. After it was deemed broken and fixed I lost a lot of torque too.

Duh. Why don't you do some research before posting. If you could read you'd realize that I've done before/afters on that dyno. I think I know what a mustang dyno reads like.

Good stuff! Your 1/8th mile trap is great and should get you closer to 115mph or more in the 1/4.

Are you carrying lead weights to the track? My '06 weighs 3340lbs with me in it(sans spare/jack) and a 1/4 tank of gas, and I'm 200lbs. Good times by the way...

The car probably has a bit more in it and I only made one pass. Shifting into 5th at about a 1000 feet out is sooo awkward and throws off my rhythm...

I don't have anything removed from the car. I weighed it on the track scale and they hosted a national NHRA event last week, so I imagine the scales are spot on.

Time for me to go on a diet.

12.4 on a 20G???? Is this a crap track? I ask this because 114mph should put you in the 11's.

http://www.iwsti.com/forums/showthread.php?t=34823
12.4 on the stock turbo, pump gas, no nitrous, full street trim.

BTW ouch F'ing MZM's dyno is BRUTAL I would take the miata there but I dont want to bother seeing a 12whp dyno chart

Congrats! I think it's safe to say that a 20g'd STi is going to consistently be a low 12 sec car. I'm sure there are a few that have made it into the high 11's on race gas/meth, but they seem to like the low 12's.

Nice, very nice...

This is what its all about, Dyno numbers mean nothing. This car is obviously truely tuned to perform, not to advertise...

This gets alot of credibility for what a sti is capable of when done properly. Too many companies are worried about the numbers they can post up thinking that is what will make them shine as "tuners". The true success stories are made by the way the car runs and drives, not the amount of horspower it "looks" like they have...

Wasn't he pulling 1.6 60fts though?

Thats a pretty heavty difference dow the line. I would imagine that Dasani would be knocking on 11's with that kind of 60ft.
