New mods...no clue about power

Well I finally have my current EVO IX MR back to the mod level of my previous EVO IX MR with only one a couple minor differences. Before I did any modding though, I had all the basics done a few months after I got the car. Had the head pulled and refreshed, new head gasket, ARP head studs, new timing belt, water pump, acc belts, acc pulley, full drivetrain and engine fluid flush, new plugs, PCV valve, EGR block off, compression/leakdown/boost tests, and rebuilt the TB with Mil.Spec shaft seals. I then installed the intake, LICP, boost controller, and injectors, and had a mild tune done. I just installed the COP, and exhaust components, and had the transmission/clutch installed, and had the car retuned this past weekend. So far it feels great, and the new transmission is amazing.

I haven't had a chance to put it on virtual dyno to see what it thinks I'm making power wise yet. Any guesses in dynojet numbers are welcome. I also plan to take it to the track once just to see what it will run in the 1/4. I am an autocrosser though, so this won't be something I do a lot of. Any guesses as to what I might run are also welcome. For reference to my driving abilities, I ran a 12.82 in my old EVO IX MR bone stock on stock clutch. So the mod list for this one is as follows:

Engine:
ETS intake
ETS LICP
Grimspeed 3 port
Megan O2 housing
Megan Downpipe
Mil.Spec HFC
HKS Carbon Ti Catback
Sparktech COP
Walbro 255
FIC 780 injectors
Forge WGA
ARP Head studs
EGR removed
Tuned to 25psi
(old car also had ETS UICP, but was only tuned to 22.5psi)

Brakes:
Steel braided lines
Stoptech slotted rotors
Hawk HPS pads

Suspension:
Stock for now. It will likely be getting the same setup the old one had.
(old car had Fortune Auto 500 coilovers 10k/12k rates with track valving)

Exterior:
Black roof/vg
SE front lip
tinted windows
Still debating on whether I want to buy another JDM rear, or just get the APR diffuser for the USDM rear.
(old car had JDM rear)

Drivetrain:
TRE 6 speed transmission
ACT HDSS clutch
ACT streetlite flywheel

I just said mild tune meaning it wasn't very aggressive. I told him to tune it conservatively, very safe, and only tune the boost up to 22.5psi peak, tapering to 20 at redline. This time I told him he could get aggressive with it, and go for 25psi, but still keep it safe. 320-340ish would be mustang numbers correct? If so, I thought about the same. Dynojet it would be higher than that.

No. 340 dyno jet sounds about right. A basic bolt on 9 makes ~340whp (24-25psi) at our local dyno jet on pump gas. If you were on ethanol, it'd be a different story.

340 seems way too low for a dynojet. Dyno dynamics or mustang, sure, but stock IX's dyno at 265ish on dynojets. My old one made 360whp on VD dynojet settings, and when run on mustang settings it did around 320ish. That seemed about right to me.

Without cams i doubt itll be any higher than 340hp on a dyno jet... On e85 definately be around ~370hp but not on pump.

I dynod on a dyno jet 330hp @25psi on pump 93 and 377hp @28psi on e85 with my evo 8 with:
Evo 9 turbo
Map o2 dump
3" tbe
ETS LICP
Precision 1000cc injectors
Intake

Then added an ETS 4" fmic and GSC s2 cams/springs and retainers and made 367hp @25psi on pump 93.

I still think you are thinking of a dyno dynamics, mustang, or another dyno of that type lol
