Interested to see how it compares to the Holinger for automation, specifically how low in gear clutchless downshifts can be managed. Also, as previously mentioned by others, interested to see it in a high powered RB as you claim Drag use, which is very hard on the drive train.

Hello Matt , let me try to expand.. Its not a easy simple one line answer

(The R32 system has not been designed in the first stage for paddle shift however its a natural development that we are working on now)

However automation is something we specialise in and you can see the types of paddle shift systems we produce working in the Dallas Performance 2000hp Audi R8.

This is working within the region of 40-50ms for shift for next gear stable coupled with a 5mm shift distance for actuation and typically 2/3rds the air pressure required because of the low stiction systems we inbuilt in our designs.

A lot of people that have seen the Dallas Lambo and Audi sequential systems think they are actually DSG such is the smooth and seamless shifting function.

Our exclusive usage of the Gill Blade 360º sensor on our barrel systems which is actually 10bit resolution provides data at higher levels than any other system in the industry , no need for filters that mask the data and the ability to log data at high speed , its the reason why Gill supply the F1 grid with sensors

This data capture enables greater visibility of dog position and allows you to characterise the dog position such that you can achieve next gear stable in reduced ,repeatable and accurate times.

In terms of power, PPG have 2400hp V6 cars running our systems running un imaginable speeds with 2000ftlb with 1600kg chassis with huge slicks on glued tracks, I guess at this point you need to see PPG is based around Drag racers and huge HP applications , its what we do.....

The thing to think about is this system is designed for the aftermarket sector ,its not a lightweight optimised system design for a particular series of racing with a HP & Torque ceiling thats been adapted from something that just happens to fit.

The PPG R32 Sequential system has been designed with the view the customers will throw everything and the kitchen sink at it to try to break it . We are pretty sure we got it covered ..... Any questions you can call or email me and i will be happy to answer any technical points ...
