Geartronics paddleshift - shift up a gear!

• A fleet of F1 cars at a Swedish Race school. The sophisticated safety features and engine/gearbox protection strategies of our paddleshift system are esential when inexperienced drivers are behind the wheel.
• All geartronics supplied paddle harnesses are constructed using Raychem Spec55 wire & DR25 sleeving with moulded & glued joints. Unlike some of our competitors, you won't find any nasty braided sleeving or cheap PVC wire in our looms, neither will you find unreliable bullet connectors and spade terminals!
• Bruce Edwards on his way to an overall victory using Geartronics paddleshift on his Honda powered Darrian. Photograph courtesy of AML Photography.
• CR1 sportscar from Denmark. This car is fitted with an LS7 engine and Hewland NLT gearbox, operated by the Geartronics paddleshift
• Another view of an Aquila CR1. The Geartronics paddleshift system is offered as a factory option on all Aquila's.
• Keith Cowie's fearsome 1200+bhp Nissan Skyline drag car featuring Geartronics automatic shift system on an OSgiken gearbox. The car has completed the 1/4 mile in an ET of 8.4s at a terminal speed of 169mph
• The Durango Lola B02/50 formula 3000 car fitted with Geartronics paddleshift. The driver is Omar Leal, winner of the 2008 Italian F3000 championship
• Geartronics director Neil Wallace and the futuristic Citroen GT concept car. Geartronics succeed where others fail - don't we Roy? ;)
• A P1-2-3 for the Geartronics paddleshift at Mugello
• A Gould GR55 hillclimb car undergoing paddleshift wiring loom installation
• The famous Zytek KVF3000 450bhp engine as fitted to the Formula3000 B02/50 Lola's
• James Hoseason's awesome Darrian uses Geartronics paddleshift.
• Fabio Onidi on his way to another F3000 win in the GP Racing prepared Lola 02/50. The sister car to this one is now racing in the European Hillclimb Championship in the hands of Joel Roussel. Both cars are fitted with the Geartronics semi-auto paddleshift system.
• Wallace Menzie's DJ Firestorm hillclimb car. This car uses a Cosworth XD engine revving to almost 15000rpm! The Lola LT1 gearbox is of course operated by the Geartronics paddleshift system
• Geartronics pressure accumulator for the pneumatic paddleshift system. Our system incorporates a high-flow pressure regulator to maintain a consistent shift force, even after a rapid sequence of downshifts.
• Display unit of the Paddleshift system. The unit not only displays the selected gear, but also incorporates a 4-stage shift light function and provides diagnostic information for the driver.
• Simon Marsh's Hayabusa powered ADR3 sports prototype on its way to a class win at Prescott Hillclimb. Unlike one of our competitors, we don't show pictures of failed installations - when we fit our system to an ADR, it works!
• A sample data log from an RFR1000 car using the Geartronics paddleshift system. Note the seamless RPM transitions (red) between each gear and the perfect gear engagement (blue). Downshift throttle blips can be clearly seen in green. All inputs were sampled at 200Hz.
• The bespoke actuator mounted on the Lola LT1A gearbox in an F3000 car
• The OMS hillclimb car of Trevor Willis. This unique car uses a combination of a Powertec V8 Hayabusa based engine and a Hewland JFR gearbox. Needless to say, the box is operated by the Geartronics shift system.
• Rear view of a Penny & Giles barrel potentiometer. We can also supply equivalent sensors from Novotechnik, Active Sensors and Contelec
• Here are the Geartronics carbon-fibre paddles installed in a V8 Star Britcar racer
• The second generation Paddleshift GCU - designed in-house by Geartronics. The unit is ideally suited for professional motorsport, and features many advanced features not found on other so-called 'high-end' units.
• GT paddle assembly with carbon fibre mounting bracket
• Serious racing cars require serious gear shift solutions. Electric solenoids and crude open-loop control methods simply won't do! This is a picture of the Lola LT1a gearbox, as fitted to the 02/50 Formula3000 cars.
• Installation on a Gould GR55 hillclimb car. Unlike most of the other Gould's that have Cosworth or Judd V8 engines, this car is fitted with a Opel/Cosworth V6 DTM engine. However, this car still uses the F1 derived Xtrac 6-speed gearbox.
• Paddleshift installation on a Hewland FTR transaxle fitted to a Jade3
• A Hewland gear and dog ring. At first glance, it looks a simple enough task to design a shift system to engage these two components. However, fully understanding the extremely complex interaction between the two is key to developing a gear shift system that works consistently and reliably 100% of the time.
• The Pilbeam hillclimb car of Oliver & Sandra Tomlin. This car uses a Judd V8 engine and a Ricardo 500Nm gearbox (same as World Series cars). We had to write some specific software for this box due to the unusual gear order.
• The fearsome Porsche racer of Richard Chamberlain. Control of the Holinger transaxle is taken care of by the Geartronics paddleshift system.
• A typical paddle installation on a sports prototype steering wheel. We can supply various carbon-fibre brackets and flippers to suit any type of steering wheel.
• Some of the Geartronics paddleshift components including the all-important intelligent gearbox control unit (GCU). The GCU is designed in-house by Geartronics and runs what we believe to be one of the most sophisticated control strategies found on any aftermarket shift system.
• A special adapter designed by Geartronics to replace the unreliable Sadev sensor with a 'proper' motorsport potentiometer or hall-effect sensor. This modification is essential for anyone contemplating running paddleshift on a Sadev gearbox.
• An actuator installation on a Sadev ST90 front wheel drive gearbox fitted to a rallycar. Unlike many other systems, our GCU has the advanced software capability necessary to reliably select neutral on the Sadev range of gearboxes.
• James Hoseason setting a fastest stage time on his way to 3rd overall on the Manx Trophy Rally. The car is a Darrian GTR which uses a Millington engine & Hewland NMT gearbox operated by Geartronics paddleshift.
• The Reynard Inverter owned by Generation Motorsport. The Honda Fireblade gearbox is operated by the Geartronics paddleshift.
• Chiron CN class sports racer fitted with the Honda K20 engine and Sadev ST75 transaxle. Geartronics were the first to perfect a reliable shift system for this gearbox, while others were still breaking them!
• Nick Algar in his Gould GR55 sprint car on his record breaking lap at Mallory park.
• Peter Kukainis and "Custard", leading the way to a class win in the 2009 speed championship using the Geartronics paddleshift system on his Quaife 60G gearbox.
• The spectacular Puch of Austria’s Georg Pacher. Despite it’s similarity to the Fiat500 this car uses a full space-frame chassis and is powered by a Powertec V8 engine producing more than 400bhp! Keep going strong Georg!!
• Another one of Georg Pacher's creations, this time the Abarth 500.
• Under the skin of the Abarth 500. This amazing car fearures a 400bhp Powertec V8 engine and Hewland FTR gearbox. As you can clearly see, such a serious piece of racecar engineering requires more than just a crude solenoid shifter!
• Actuator installation on a Pankl F3 gearbox.
• Actuator installation on a Sadev ST75. Unlike very heavy & cumbersome electric solenoids, our compact pneumatic actuator will easily fit without the need to re-design wishbone or wing mountings etc. Remember, we've been operating the ST75 for years!
• A neat installation on a Ricardo 500Nm gearbox. Unlike some systems with their crude & massive solenoid actuators, we have no packaging problems due to the very compact nature of our pneumatic actuator.
• The throttle blipper installation on a Porsche 996 RSR. We only ever use compact and high-powered pneumatic actuators, unlike some other systems that use a solenoid-based contraption designed to give an un-nerving push on the driver's pedal!
• It's a tough job, but someones got to do it! With the paddleshift installation complete, we just need a driver to test it...
• Formula1 test driver, James Rossiter, in the Hayabusa powered Reynard Inverter. When James tested the car at Silverstone, he commented that the Geartronics paddleshift system was "perfect". Some endorsement indeed, from a driver more used to the seamless shift technology of F1.
