We did get it on the dyno today. Hopefully get dyno charts up tomorrow. Basically its going to be tough getting an accurate number. The new motor is much more efficient with the PnP on the head and boost hungry with the new displacement that getting the boost to be the same as the previous dyno is not going to happen without the help of a different BCS.
We are working on it.

. Seriously though, it is pretty exciting to see you guys put this thing through its paces in-house. I really appreciate the time and effort AMS puts into builds like this and the resulting post here on evom.

Time for some results!!!!
Some facts about the before and after dyno runs below.
The boost hungry 23RR was eating more boost than I could supply with just the manual boost controller that we were using on the stock motor. AEM Boost Control to the rescue! I checked the old logs from the last time I tuned the car and saw that it was holding 22psi at redline. Knowing this, I used the AEM to add duty cycle to the solenoid as the RPM's increased to keep our same boost level, resulting in a rock solid 22psi once again.
Fueling obviously had to be increased dramatically to help cope with the amount of air that the motor is drawing in. I had to add quite a bit of fuel in the 5500 to 7000 area where the top end of this motor was really shining. In addition to this, you can see that the motor is ALSO spooling a good 400-500 rpms earlier and making more torque EVERYWHERE! At 4000 rpms, we are making 100ft lbs MORE torque than with the stock motor. Very impressive.
Every change that I had to make in the AEM spoke volumes about the efficiency of this motor. This ‘little’ turbo is killing our power production right now and I can’t wait to see what Its going to do with the new cams, bigger injectors and a 35R!

Whoa! Peak torque and WHP come on so much ealier than on the stocker. The original dyno plot looks like the GT30 and the 2.0 block were made for eachother and this one looks like they are fighting it out. Time for a bigger turbo! The anticipation is killing me. Nice work! You guys are the best.
What would happen with more boost if you are having to work so hard to tune it at 22psi?

WOW! 100 more ftlbs from 3500-4500!!! And then increases, rather than falling off like the stocker, to 6000rpm. Wholly sheet!!!
Chris, what fuel was this on? What cams? AEM Tru-boost or AEM EMS taking care of the boost and engine? With or without mass air flow sensor?
I know my GT3076 loves 30psi and race gas, at 22 psi its seems its in relax mode.
Looks like 500whp is possible with this setup with rediculous amount of response and low end torque. I likey!
Great job!

Is it just me, or do those gains not seem to justify the cost? ... at least when I compare it to the results of my current setup. Granted the 2.3 does make more power, but I would have thought the difference would have been greater...

See below:
I got the car up and running today. Purrs like a kitten. We will be breaking it in and then will put it on the dyno to get another dyno chart which shows what the gains of the motor alone are.
The mods before and after the motor are AMS GT30 kit, AMS VSR intake, GSC S1 cams, AMS turbo back with HFC, AMS FMIC, AMS LIPK, AMS UIPK with Tial BOV, AMS MBC, 880cc injectors with AEM EMS controlling the mix.
The motor is the only thing changed. It went from stock to the 23rr.
Once we get the before / after motor dyno finished, we will be swapping to S2 cams, GT35 turbo and 1000cc injectors.

So, now I have to wonder, if the S1 is considered to be a mild cam (maybe somewhere in the neighborhood of HKS 272 cams), what would the expected gain be with the S2 cams? Furthermore how do you guys (AMS) feel that the S2 cams stack up to the HKS 280 cams? I feel like I still have some room left in my current setup and would really like to hear some thoughts on what cams would provide better topend...

You sir are REALLY going to benefit from Martin's massive cam test he just did for turbo magazine. We can't talk about it until the issue comes out but once it does you will have all the lovely cam info you need for your EVO 
It should be on news stands VERY soon...two weeks I believe.
