I'm going in, cover me... (Built 1.8L GT2871)
At long last I will be taking the '99 NB to the dyno tomorrow. I'll be using the Dyno Dynamics Dynamometer (load bearing, eddy current) located at Henderson Performance in New Braunfels. Cory, the dyno owner, will be operating the dyno, and representatives from BEGI will be present to assist with tuning. I'll be driving WARI to adjust the Adaptronic maps.
The goal is 300+ RWHP, but above all to make it a strong, non-marginal tune on 93 oct pump gas. We will tune for MBT and knock onset (whichever comes first) without the water injection, then back off a couple of degrees. Then I will add the water injection on top of that for additional margin. This is a daily driver so the goal is fast but reliable.
Build Details:
Short block:
1999 NB 1.8L
Stock Crank (meanest stock crank on MT.N)
Belfab rods
FM Wiseco pistons, 9:1
all balanced
Cylinder head:
1999 cylinder head
Supertech oversized valves, undercut
Supertech Valve springs and titanium keepers
Stock 1999 cams and pulleys
Induction/Exhaust:
DIY cowl induction
DIY v-mount Ebay intercooler with DIY charge plumbing
Tial-Q BOV
DIY gutted 1999 manifold (no more VICS)
1100cc (each) Bosch EV14 injectors from Fuel Injection Clinic
Port water injection (8 GPH total, DO recirc style pump, Aquamist high-speed valve controlled by Adaptronic)
BEGI S4 tubular manifold
Garret GT2871 turbo, 0.64 A/R, Anti-surge compressor housing (ATP Turbo)
BEGI SGDP, stainless
Full Enthuza 3" stainless exhaust with high-flow cat
Drivetrain
Lightened 1.8L flywheel (inertia ring removed)
ACT XTSS clutch (flywheel and pressure plate balanced as an assembly)
Mazdaspeed 6-speed transmission
Torsen with 3.63 gearing (sweetness)
Cooling:
EBay oversized radiator (DIY v-mount)
Spal 11" low profile fans with DIY cowl
DIY Coolant reroute. Thermostat regulated heater core loop, dual oil-to-water oil cooler sandwich.
Fully ducted between radiator and nose
Electronics:

Fresh NGK BKR7EIX (Iridium IX) plugs gapped to 0.030"
Innovate LC-1 WBO2 (logged)
Innovate TC-4 Thermocouple Reader (logged),
Thermocouple in exhaust flow, located in exhaust collector before turbine inlet
Electronic Boost Controller (Adaptronic controlled) with Manual boost controller in parallel (hybrid)

I'll cut to the chase
~290 RWHP @ 18psi. Corrected only for altitude, added about 10 HP. I guesstimate ~340BHP. This is on a Dyno Dynamics dyno, so presumably it would read higher on a Dynojet. Water injection is off.
This is with conservative timing, about 14 degs advanced @ 18 psi. There is a lot more there with more boost and timing but I like my engine, trans, and diff in their current state. It's pretty quick, spins the tires in third @ 50 mph.
EDIT: Forgot to mention the AFR was 11.5:1.
