Description
When you want the best – this is it!
The HGT paddle shift system represents a significant advancement in race car technology, offering numerous benefits that reduce installation time and enhance both performance and driver experience. Central to its appeal is the system’s ability to deliver ultra-fast gear shifts, which are crucial in motorsport. This paddle shift system enables seamless, instantaneous gear changes at the mere flick of a paddle which translates to reduced lap times and improved acceleration, giving drivers a critical edge on the track.
We’ve engineered this system totally in house for reliability and durability using the highest quality materials and technology to provide what we believe to be the best paddle shift system in the world. To start; we’ve used the highest grade carbon fibre available, not common low-grade compounds you see in value-priced systems, nor carbon fibre veneer over fibreglass like some in the budget range. As you compare HGT pricing vs competitors, remember the HGT system comes wired and terminated ready to install with tefzel wiring, 90-degree boots for minimum wiring fatigue and Raychem heat shrink protection. For an apples-to-apples comparison, you’d need to factor in at least two days of local professional labour or maybe more time if you intend to wire yourself.
When it comes to rotary switches; Grayhill from England are considered to be the quality leader so we have 4 of their 12 position units to provide fine control over the functions you elect to assign to these switches. We’ve designed and built our own PCB’s to run off the back of the Grayhill switches for precision; and chosen Omron micro switches to signal the up and downshifts to the ECU. On top of this there are 8 momentary switches to assign as you see fit. Two years of driver feedback from race testing has allowed us to fine-tune the magnet and spring setup to deliver the ultimate shift feel.
Krontec are the gold standard when it comes to quick connect systems and when combined with a pre-wired single 22 Pin DTM connector plug, you have the ultimate in reliability.
Our engineers designed our billet CNC valve body casing with aerodynamics in mind to provide maximum fill and exhaust flows to ensure the fastest feed and recycle times. The coils have been chosen specifically for their rapid charge and discharge properties to minimise response times. Our gear shift actuator is equipped with Viton seals to cope with the extreme heat they need to endure due to the usual close position of red hot exhausts. The HGT actuator has been designed so that the cylinder fills in the absolute minimum time to provide the fastest possible shifts with pressures as low as 4 bar.
The accumulator is made from billet alloy which is CNC’d for the ultimate quality with a solid high-quality carbon fibre base for secure mounting in your race vehicle. The anodized accumulator mounts in the upright position to minimise footprint consumption. Its fitted with a stainless steel purging system that can be controlled via the ECU to enable water trapped in the accumulator to be purged on startup – you’ll never have to remove the accumulator to drain moisture.
The compressor and accumulator combination have been matched for the minimum weight and correct amount of air to ensure the compressor does not exceed 40% duty cycle whilst allowing 5 downshifts in a second – you’ll never run out of air. The compressor, valve body and actuator combination have been tested in 25-hour endurance races consuming over 22,000 shifts in 100°F /38°C ambient temperatures with 75% humidity, without a single issue or misshift. You typically purchase one Paddle Shift system in your racing lifetime so you might as well buy the best and race with confidence.
