 Cordona PQ8 Quick Shifter Kit
Manufacturer: Cordona

About the PQ8, Precision Quickshifter 8


A Cordona PQ8 Shifter is a high-tech device that will increase the performance of your motorcycle or anything powered by a motorcycle engine by enabling lightning fast up shifts without backing off the throttle or disengaging the clutch, electronically. The PQ8 Shifter has been developed by professional road racers as well as beginners, it has high quality internal components from the U.S. the E.U. and other countries.

Performance

A normal up shift usually means that the engine is disengaged from the rear wheel/gearbox for a distance covered of about 3m/10ft, depending on how fast the vehicle is moving. Vortices are also produced in the intake manifolds due to the closure of the throttle, something that will restrict the flow of air into the engine when the throttle is opened up again.

With a Cordona Racing Shifter the distance covered at upshifts will decrease to about 1m/3ft and no vortices will occur at the air intake since the throttle is kept wide open at upshifts, in fact, everything is wide open, from throttle bodies through the engine out the exhaust, airflow is going. The ignition will be interrupted for a fraction of a sec only. This will make up for a lot of ground on a lap around a road racing track or on the 1/4 mile. By installing PQ8 Shifters on test bikes we have lowered 1/4 mile times with 0.2 sec. We have also lowered lap times on a road racing track by as much as 1.5 sec/lap. Usually 0.2 sec. on the 1/4 mile and 1.5 sec. on a road racing track means parts and engine work for at least $3000.00.

You can probably imagine yourself a race to the flag between two racers on identical motorcycles with the only difference being that one of them has a PQ8 Shifter installed. The rider on the bike equipped with the shifter will edge away from the other at every up shift and most likely cross the line several meters/yards in front of the other rider.

The Cordona Racing Shifter is smaller and lighter than its competitors, the whole kit is only 300g , kill box measures 95x70x28mm.


What's in the kit?

The Pq8 kit includes The CPU, Plug and play wiring harness, a pull switch, stainless steel bracket, stainless steel pull arm, velcro for mounting kill box. All kits include step by step instructions in English.


Installation

Installation is usually completed in an afternoon with common house hold tools, i.e. no need to be a bike mechanic to experience lightning fast upshifts. Fabrication of a simple sheet metal bracket is needed for some motorcycle types, where the included bracket won't fit. Most kits are sold with Our GP switch as a Combo kit and a GP switch bolts right on. The PQ8 will fit all bikes on the market.
Technical

The Cordona Racing Shifter works with a switch attached to the gear linkage of a motorcycle, the pull switch sends a signal to a "kill box" that will interrupt the ignition for a computer controlled time when the gear lever is activated. While the kill box interrupts the ignition, the drivetrain will slack and the next gear will engage and immediately thereafter the "kill box" turns the ignition back on again. The whole up shift is done without touching the clutch or backing off the throttle.

The PQ8interrupts power to the coils, between the ECU and coils. The PQ8 uses new thinking to inhibit ignition and WILL NOT affect injection lights like most other shifters on the market. In fact the Bike ECU won't even know the ignition was inhibited.

Some other shifters cut the power to the CDI at high RPM and cause damage to the ignition system.

Please note that the PQ8 does not just ground out the coils with the kill button loop like some other shifters, something that will cause misfiring and eventually damage to the engine.


There is no extra wear on the ignition system due to the use of a Cordona Racing Shifter since the shifter is only turning the power to the ignition coils on and off , with the help of advanced internal anti misfiring components. The wear on the clutch is actually reduced since it is not used at up shifts.



Any motorcycle can easily be returned to its original ignition system in the event the owner is selling his bike and would like to keep the Shifter. The PQ8 comes with plug and play connectors for most bikes.
