Hi There!
We offer two level of kits for the Gen. 2 5.2L V10. (2016+ Audi R8)
VF800 - $29,995 - 805HP | 600TQ on 91 Octane Fuel
VF8XX - $36,995 - 825HP | 625TQ on 91 Octane Fuel, and up to 890HP | 675TQ on Race Fuel.
The primary hardware difference between the VF8XX and VF800 is a modification to the fueling system of the car. The VF8XX system includes an upgraded intank fuel pump which allows for high fuel pressure at high boost, and more power. The upgraded pump also allows a higher concentration of Ethanol fuel to be used which allows us to approach 900HP safely.
With the R8, you can swap between maps in just a few minutes. Meaning you can cruise around on a pump gas file most of the time, and swap to the ethanol file when you're at the track or filled up for a canyon drive.
