Building such powerful GT-R modifications, the Litchfield studio aims to prove their performance and skills, and so they invited the well known Castle Combe Circuit in order to test the upgrades on the chassis of their Nissan GT-R.

The engine power was increased from 550 to as much as 900 hp. To achieve such a growth in the power of the bi-turbo petrol 3.8 V6 engine, it was necessary to amend the turbocharger, intercooler, the air intake and exhaust systems, as wells as the pistons and the connecting rods. The acceleration to 0-100 mph was reduced from 2.7 to 2.3 seconds, and the top speed increased from 315 to as much as 350 km/h.
