That is quite a set up. What did you do to the FI to keep up?

Thanks for posting Balacco,
Yes we did add an exhaust VVT.
I got 169 HP at the wheels when it was completed in the Spring 2007 and at last December's (2008) dyno .........much faster then JohnM's white Spider. 
I have an Autronic SM-2 ECU that handles the FI and operates the intake and exhaust cam independently. I also have an Autronic 500R CID ignition box with 4 MSD Blaster coils for a direct fire ignition.
The whole thing was engineered out by my engine builder Steve Schwitters (an Aeronautic engineer and old time Alfa racer).
The engine was basically race prep with larger valves, wild cams, custom design pistons, balanced and lighten internal engine components, baffled oil sump, aluminum flywheel, 5 1/4" Tilton race clutch and more.
We went to larger injectors to handle the extra airflow from the individual throttle body's and larger valves but stayed with the stock exhaust manifold.
We also switched out the 4.10 rear axle to a 4.56 and locked it out to 47%.
The whole project is covered in "Msiert Black Spider Project" the link is at the bottom of the page.
