Tenrai Cluster IV Ultimate G

The **Tenrai Cluster IV Ultimate G** is a Gymkhana Jammer created by JustAlex93.

## Details

The Ultimate G is a variant of the Cluster IV, specially built and prepared for intense Gymkhana driving, particularly for a Gymkhana video production by Tenrai's U.S. branch, Tenrai Motorsports USA, and Vermont RaceWorks (VRW), which made the car. It was driven by Davis Paskin, a professional motorsports driver, stunt performer, and an X Games gold medal winner in multiple disciplines. Despite what appeared to be reprehension on Paskin's part as pointed out by some people who viewed the Gymkhana video, his performance proved very solid, also demonstrating the Ultimate G's immense horsepower and agility.

Paskin had also used the Ultimate G to set a new record at the Mount Washington Hillclimb Auto Race in New Hampshire, beating his previous record attempt.

The Ultimate G is a true custom jobby with a serious amount of kit, boasting a good amount of the components coming from VRW's own workshop, as well. Distinguished by its 3D-printed hood-exit exhaust pipes and the aggressive aerodynamics (including a multi-element rear wing with an active upper element) on its custom carbon fiber body, it consistently makes a statement.

The engine is a VRW-built 4-cylinder billet block boxer with a displacement of 2.3 liters, a Barrett turbocharger with a front-mounted intercooler, a dry sump oil system, a VRW twin-belt timing system with carbon fiber covers, a VRW inlet manifold also with a carbon fiber cover, DLC coated camshafts, sodium-cooled valves, and a VRW anti-lag system with turbo management. Oh, almost forgot; The engine makes 862 brake horsepower with 664 lb-ft of torque!

The electrics consist of a British Rosworth ECU with a lightweight motorsport wiring loom, electric power control module with switches, and a Rosworth data logger.

The Ultimate G's transmission is all-wheel drive, with a VRW front diff and Radek rear diff, custom driveshafts and prop shaft, a triple-plate carbon racing clutch, and a Radek six-speed sequential dog-engagement gearbox, controlled with a VRW carbon fiber gear lever.

For cooling, the vehicle has a PWR radiator in the rear seat area with custom carbon fiber ducting.

The Ultimate G uses Kreiger suspension with VRW tubular front and rear crossmembers, suspension arms and links, and hubs and spindles. It also has a custom steering rack with a 11:1 ratio, and a motorsports high-flow power steering pump.

It also has 18" M.O. 250 Rally wheels, a custom FIA-spec roll cage, CREARO racing seats with head & neck restraints (HANS), high performance tires from Yashima EDGE, 350mm front and 320mm rear racing brakes with Eternal NF20 SDQ002 brake pads controlled with a VRW carbon fiber hydraulic handbrake, and FIA FT3.5 fuel cells (35+ liters), polycarbonate windows and windshield, and a multi-chamber fire suppression system among other features.

The M.R.A., showing interest in this unique variant of the Cluster IV, commissioned VRW to construct a number of additional Ultimate Gs for use in the MotorStorm Festival.
