Default I'd like to play a game- guess my horsepower before I hit the dyno Saturday!

Ok I am going to the dyno Saturday. What do you guys think I will put down? I have an idea but would like to hear your opinions.

Dyno: Dyno Tech's mustang Dynamometer

Tuner: Jay Perry of Perry Tuned

Car: 2002 Subaru WRX Wagon MBP

Mod List:

Power:
-30k Stock EJ20 Long Block

-Perrin Turbo Inlet
-Perrin After-MAF
-K&N Drop In Filter
-STI Spec-C Long Runner Intake Manifold (no tgvs)
-3mm Phenolic Intake Spacers
-Maddad UEL Header
-Maddad Cattless Up Pipe
-Stromung 3" Divorced Short Down Pipe (custom cattless lower section)
-Stromung 3" Catback
-Turbo-XS TMIC
-Forge BOV
-Hallman MBCS
-NGK 1 Step Colder Plugs

I think that is about it.

Also do you guys think it would be beneficial to use a K&N Typhoon short ram intake with "heat shield" or just keep the stock box with K&N drop in and Perrin after MAF?? I have both.

Well its already been street tuned and is pushing 23psi tapering to 18psi.. Jay says there is a good amount left to go but I do not have a wide band yet so we are going to fine tune it saturday on the dyno.

Hmm. I'll revise to 265 hp / 265 tq after being tuned on the dyno. I've never had a vf on a 2 liter at that high boost, so I'm guessing on torque.

I don't think it'll break 260. Mustang dynos always read low.

IIRC they guys at Dyno Tech said it was 13 or 14% less than the Dyno Jet down the street at DEZ Racing.

I also have a Hybrid EJ25 in the works. CP pistons and STI Rods. I need a new STI crank, one STI rod, a new Rod bearing and piston rings. Heads have already been machined for the EJ25 Block w/ new valves etc. But we will see when that happens. I have enough money out as it is lol.

Stock 2.0 WRX peak on that dyno make 160-170whp and about the same or slightly higher for torque.

Most EJ205 VF cars w proper supporting mods make around 270whp and 270-300wtq depending on the peak boost level.

I'm guessing 15% less than you anticipate it will.

Can we play hungry hungry hippos instead? This game is depressing.

Just keep in mind, there's a lot of things that can cause variations in the readings. Anything from how the car was strapped down, how aggressively the dyno is loaded, slight errors in calculating the WCF, how aggressive the tuner decided to lean on timing for the given load on that day, etc. I like to see consistency over a few days.

Exactly what this guy said.
What Octane? 89, 91, 93, 110, C16
How hot/humid it is that day
The list of variables can go on "fuh dayz"

I've had a couple of my previous cars tuned by a couple different people here on the forums and the same car w/o any difference in modifications they were 0-50awhp difference between the tuners and the corrections they used.
