Credit for finding this article goes to MattM. He posted the article in the 997 section but I think some of the 997TT guys who don't check the other sections might like to see this.

The experienced team of technicians from Jürgen Alzen Motorsport in Betzdorf is responsible for the technical design and for building the car. The engine is based on that of the latest 997-series Porsche 911 Turbo, and comes from RS Tuning. H&R contributes its immense know-how in the field of suspension design and setup.
Favorable aerodynamic properties are essential for a car that is designed to break the 400-km/h barrier. Minimizing frontal surface area is absolutely elementary, which is why Jürgen Alzen decided to lower the roof by 75 millimeters. At the same time the A-pillars were tilted back further by 5.5 degrees. To give the coupe a homogenous overall appearance the tilt of B- and C-pillars was adjusted accordingly. Special flush-mounted polycarbonate windows all around complete the roof conversion.
Also part of the MISSION 400 PLUS aerodynamics concept are numerous other modifications that were developed and tested in the wind tunnel. Among them are a long rear with pronounced separation edge and the absence of rain channels. Streamlined cowlings for the 18-inch BBS light-alloy wheels will reduce air turbulence on the vehicle’s sides during the record run.
The MISSION 400 PLUS engine is built by RS Tuning in Kirchhaslach, where the racing engines for Jürgen Alzen Motorsport have been created for many years. The displacement of the six-cylinder flat engine is increased from 3.6 to 3.8 liters and the engine is reworked entirely. Company owner Reinhold Schmirler’s power cocktail also includes special combustion chamber shapes as well as precision-machined cylinder heads with larger valves, and high-performance camshafts.
The engine’s peripherals are also completely new. In addition to an intake manifold with larger and smoothened ports the engine is equipped with a more powerful turbocharging system and a high-performance exhaust.
The stock turbos with variable turbine geometry are replaced by larger conventional ones, which are supplied with optimal amounts of exhaust gas by the custom-tailored stainless-steel exhaust manifolds. Higher capacity intercoolers provide cooler charge air for maximum power output, aided on the exhaust side by a stainless-steel sport exhaust with metal catalysts.
RS Tuning’s stationary test bench is used to fine-tune the perfect interaction of all individual components with special 100-octane fuel mapping for the Bosch-developed engine electronics. With a boost pressure of 1.5 bar the engine develops 1,054 hp / 775.7 kW at 7,700 rpm and a peak torque of 1,030 Nm at 5,800 rpm. And yet, the speed-record hunter meets stringent EURO IV emission limits.
Power is transferred to the rear wheels via a high-performance clutch and a modified high-geared six-speed transmission.

I had a few word with the marketing manager at Essen Motorshow.
At the moment the car has a GT3 engine. With turbos it will have the air intake where the rear windows are.
The roof is lowered and the a-pillar is more aerodynamic, less angle.
