Engine and EFI project almost complete

I guess I haven't posted the full details of my never ending project on the new 930 forum. I was going to wait until it's finished, but I was at the tuner's yesterday and I just had to share.

Engine details:

3.4 JE pistons w/7.7:1 comp
Mahle fully finned cylinders
Pauter rods
Twin plug
Heads matched to Carrera intake
EBS perf valve job & springs
964 cams
B&B header & custom muffler
Motec M600 ECU
Wasted spark ingition M&W Pro-14 CDI and 6- dual coils
Patrick flywheel
Custom intercooler from 25 x 10 x 4.5 Bell core
Tial 46mm wastegate & blow off valve

The tuner got most of the fuel mapping done and some of the ignition mapping. Before we called it a day he made a couple of full dyno pulls. The boost was set a 0.7 bar, the intercooler was hot, and it made 390 rwhp. I'm hoping for 500rwhp at 1 bar, but I don't know if we'll get there with some more tuning and a cool intercooler. The power and torque curves are very smooth, I'll try to get a copy of them next time I'm over there.
2014 Cayman S
2011 Cayenne Turbo
1979 930 (475 rwhp at 0.95 bar)
