The Ultimate Pump Gas Turbo.
I've been driving my EVO9 around for the last couple of months with a huge grin on my face. I "de-tuned" my 630whp setup down with a more responsive setup for the street. I took the big 5R cams out, and I took the big FP Black turbo off and swapped back to my 4R cams and a 73HTA FP Green turbo for better pump performance. I knew it was running really well, and I saw a few other threads where guys were bragging on their daily drivers so I figured why not head over the Cobb Tuning here is Plano and do a few pulls on their Mustang Dyno?
So anyway, I topped the tank up with 93 octane Mobil gas this morning and sent Scott Evans our R&D test Tech over with the car with the instructions to "find the bottom of the well or 500whp, whichever comes first". Mission accomplished.
Here is a little rundown of the specifics of the car as it sits today.
2.3l 9:1 motor, no bal shafts, eagle rods.
FP 4R camshafts, intake and exhaust
FP beehive valve springs
Stock valves and guides
Buschur Racing FMIC, not sure which one but its about 3" thick
Works 3" cast O2 housing WITH support bracket, no WG dump
full 3" exhaust system
Excedy twin ceramic clutch
IDC injectors, don't remember the size
FP 342 in tank lift pump and Bosch inline pump Weldon regulator 90psi base fuel pressure
Ported stock intake manifold
enlarged stock TB, dont remember how much it was enlarged, not much
Stock Exhaust manifold, unported
FP 73HTA Green model turbocharger with 84mm inlet
For control we use a Motec M800 ecu because Motec is the best.
I'll ask Scott to screen capture a data log here in a little bit to show everyone what the lamba, ignition timing, boost pressure etc looked like during the pull. I'll may even put the cam position stuff in there in case some of you are interested in how we manipulate camshaft timing to widen the power band like this, but I hope I dont get a bunch of people telling me that we are doing the camshafts wrong
I just can't stop talking about HOW MUCH FUN this car is to drive EVERYDAY! That 465whp of trq hits like a hammer right in the late 3krpm range, and the 500whp on the top end is fun too for when I feel like revving it out, which I rarely do since I am a lame short shifting SOB
Enough talking here is the chart. I hope some of you enjoy your EVO's as much as I enjoy this one, it is AMAZING, this is truly the "Ultimate Street Car" combination!
The date on the print out is tomorrow for some reason, I am not trying to indicate that FP turbos are capable of time travel

Jerry-
The injectors are ID1000's from T1 Race Development/Injector Dynamics at 75 PSIg base pressure thru a Weldon regulator (only viable regulator capable of handling 100+PSIg control). FP 255HP in-tank feeding a Bosch 044. Note Inj DC numbers.
I will post a screen shot of the log in a few.

I left off a couple details on the engine I forgot about but I know someone will ask.
The head has had the chambers reworked a bit, standard valve job, and a very quick light cleanup in the bowls, stock valves, that's it.
Ignition system is a scratch built system we like thats 4 channel inductive COP using a new Bosch true motorsport coils with built in ignitor that costs WAY WAY too much to produce or market but works too well to change and no I will not build you one so dont ask
EDIT: Also wanted to point out that the car still has a fully functional EGR and purge system.

More Trq in the midrange, the turbo is designed to run up to 155krpm or so, running past that is operating outside its intended range, but possible. So if you bring it up to 155krpm in the midrange you can fill all that in with trq and run 35+ in the middle if ya want, but this is 93 octane so ill advised

Damn that a sick *** powerband.
Great data, really interesting to see all that information. What are the standard conditions used on your "corrected airflow" data?
Based on the turbo speed and airflow, it looks like the turbo is maxed out around 55 pounds/min? Very impressive considering it's breaking 300ft-lbs around 3000 RPM.
What MAF sensor are you using?
