Ok, I am crashing soon so will be editing and adding to this post in the morning. Didn't want to keep everyone waiting so at least wanted to get some initial impressions and the dyno up.
First, I really want to give a HUGE thank you to Gruppe-S for the awesome work on the installs, and especially Mike for the awesome tuning and late night work.
For the dynos, the first was done at the free Gruppe-S Evo dyno day. Mods at that time were - HFC, cat-back exhaust, 264/272 cams, and ECU reflash tune. Even at that time the AFRs were getting around 11.9 on the top end. We really weren't able to do an immediate before dyno tonight because of the shape the car was in before Gruppe-S fixed it up, so we had to use this one as the "before".

Tonight, Gruppe-S installed the Evo IX turbo, tubular O2 housing, 3" downpipe, MBC, and injectors. (cam gears were also added previously). The car was Ecutek tuned by Mike.

As you can see, great gains in power and AWESOME torque gain. With the addition of the O2 housing and downpipe, I was not expecting much at the low end/torque...figuring I would be swapping that out for more top end. This was not the case at all and the low end is amazing. Most importantly, the turbo spools up so much quicker and the torque is VERY steady all the way across. The boost is at 1.5 bar and stays that way with very little taper all the way to redline. Also, the AFRs were at a safe 11.2 max at the top end.
Driving impressions - DDAAAAAAYYYYYAAAAMMMMMMMNNNNNN! :shock:
The power comes on so quick and is SO smooth. There is no lag to speak of...step on the gas and the turbo is there. All the way to redline the power is rock solid and strong. A spirited entry on to the freeway through all the gears was enough to make the butterflies in the gut do acrobatics. Cruising in 5th and then gassing it a bit gives you plenty of kick with no need to downshift. I can go on and on later, and of course will give rides to anyone seriously considering this mod.
Reality check: As awesome as all of this is, there is still PLENTY of power left to be had. Keep in mind all of this was done on an 03 Evo with 63k miles. I have 264/272 cams not straight 272s or 280s. There also was some cam noise that we think may be affecting the knock sensor as there still was some timing to be had that the ECU wasn't giving up. This also was all done with just a HFC...test pipe would really open it up more. The dyno runs were also done back to back with little cooling in between...all pulls were close, consistent, and predictable. The highest numbers of the night were actually the last run when the car was hottest and the room was making me high in the lobby. :lol:
What does all this mean? With the price of the TMEs on the rise, it really is a slam dunk mod. I truly think the power delivery will shine on track, and also look forward to trying it out at auto-x as the style of power delivery will be even more useful there I believe. Basically, any 03/04 with the 9.8 hotside will flip out with this mod. 05s who already have the 10.5 hotside MAY not see as dramatic of an increase, but the quicker spool, more solid power, and predictability of the turbo will still more than make it worthwhile.
Thanks again to Mike and all the guys at Gruppe-S! :thumbsup:
