From my post on the NorCal Evo site:


Some of you may know that I went to Works this week to get some upgrades... some may not. Here is a copy of the post from the MR site and Norcal evos:


OK Im back! I had a good time on this trip and I am very happy with the results. For those of you that are not following this thread, here is the information:

2006 Evo9 MR (the faster silver color)
1800 miles
Works drop in air filter
Otherwise stock
Full Function Dyno (According to Sean, the owner, it dynos about the same as the Groupe-S)

Baseline Results:

Max HP: 239
Max TQE: 235

We did 3 pulls, and they were all within a few HP of each other, and that is the way we did all our tuning, 2-3 pulls each time to make sure that there were no fluke or inaccurate readings, and the numbers were always repeatable. The numbers throughout ALL the pulls were super close to each other.

Modifications Completed that night:

Works Bored Throttle Body
New Works O2 Sensor Housing (Ceramic Coated)
Works DP (Ceramic Coated)
Works HF Cat
Works Intermediate Pipe
Works Exhale HF Muffler
Works P2 Flash/Boost hose

There was a problem with my ECU, it seems that my car (manufactured in Oct 05) has a new, later model mapping flash, so it would not work with the ECUTeK. Pete (the owner of Works/tuner) was able to send my info to EcuTeck, and get an updated code for my ECU. I really makes me wonder what changes were made to the program?

Anyways, once that was sorted, Pete (the owner of Works) took me out and did a couple hours of on the road tuning/reflashing before we went to the dyno to fine tune the maps.
Dyno the next day, the same dyno was used (full function).


Max HP: 297 (increase of + 58 HP)
Max TQE: 268 (Increase of +33 FT/LBS)
AFR: 11.2 across the board, until Very high RPM, where it richens up a bit.

This was after about 2 hours of road tuning, and 2 hours of Dyno Tuning. The only adjustments made were fuel, boost, and 1 degree of timing in the high RPM range. Pete could have more than likely picked up some more power with another degree or so of timing, but we decided to stay conservative with the Cali ****-tane fuel that we run. During all the dyno tuning and road tuning, my car never pulled any timing. Pete was very happy (even suprised) with the numbers that this sucker produced.

Needless to say I am very happy, and my car just pulls like a beast. The parts that Works provides are of the highest quality that I have ever seen (not to mentioned the fit was perfect). The Techs that did the install really treated my car well, and were very helpful in answering my questions. If anyone here is wondering if Works is worth the extra money... I say go for it. Ive seen so many problems with parts of poor quality that just don't fit right, and to me it is worth it 100%.

Here is my before/after dyno sheet:

New Works ride springs and rear sway bar. The ride springs are AWESOME with the Billies. This is the way the car should come from the factory. It takes bumps better, doesn't lean, corners very flat. even though the car is 7/8 inch lower, I believe that it will have less of a tendancy to bottom out because the car does not flex down on bumps any more. I highly reccomend this setup, and it's not that expensive at all. I highly doubt I will ever need coilovers. The rear sway bar is sweet as well.




Race Cars:

 

Hey works said they were going to be more aggressive. You results look pretty good.

 

How much did you pay to get those results?

 

Good numbers on a Mustang dyno no less. I wonder what the numbers would be on a Dynojet?

What is the diameter of the DP? What is the spring stiffness and do they work for a regular EVO?

 

Every part I got from works was perfect. These guys know what they are doing.

 

At least $2800 for parts alone going off the WORKS site.

 

Is it me or is the torque number low vs. EcuTek tuned 9's with TBE's on 91 oct?

 

yea it is a bit low, at least the peak number, it's hard to judge his actual power curves with the trace chart he posted.

Kawrider, do you have the normal mustang dyno output as well?
