What are the pro's and con's when we compare electric paddleshift systems such and the flatshifter expert with auto blip and the cable systems such as the ab performance one?

for 80% trackday and 20% road use...

electronic one will prevent you downshifting by mistake and blowing an engine?.

sounds stilly but it only has to happen once while trying to learn the car....

The cable paddle shift provides better feedback and a more involving drive. You feel properly connected to the engine through your fingers. It isn't quite as quick though.

If you're going electronic you really need closed loop. Geartronics are the best in the business in terms of that crossover of price and performance.

Having had bike engine cars for 10 years my gut feeling is don't put any electronic powershift system on your engine. My friends and I have had very little problems between us over the years ( mine was perfect for 6 years / 40,000 miles before breaking, which might not sound clever by car standards but that is a LOT of use at 10 / 10th's trust me ). More often than not, when I hear of a BEC gearbox failure it has had some sort of powershift system in use at the time. I imagine maybe once every 500 shifts (?) I would feel a resistance, to which I just release and re-apply pressure for a slick change the next time 1 second later. A powershift would just smash it home no fuss, but it cannot do it any good? I don't know why they sometimes baulk they just do, but it is no big deal.

I am currently doing a nut and bolt rebuild to my BEC and will probably switch from a tunnel st to steering wheel shift just for a change, but no way would I put any powershift system on mine.

I am sure some will have no issue with theirs but its your personal choice.

The Flatshifter "Expert" system does not use a power shifter.
It uses a conventional manual shift system (rod or cables).
The 'Expert" system uses an up-shift delay and a down-shift blip to assist the clutchless gear changes.

The cable system can be incorporated into paddles behind the steering wheel.

Flatshifter also manufacture a power solenoid version which can be added to the Expert system.
As others have said, a power system will try and bang the gear in and needs to be correctly set up.

Do the best "power" systems have the ability to sense resistance and back off? Without that the best set-up and adjusted system in the world will still force the occasional dodgy shift, and they are the ones which cause wear and damage not the other 499 perfect powered shifts. Probobly fine for a low-mileage race car but I still would not fancy one on a high mileage road car. A well set up manual system only requires a 1/2" flick of a lever or paddle and bang in it goes anyway, never understood the need for electronic assistance? I would love to try a latest generation powered system saying that, just not in my own car!

They do but only closed loop systems - hence my Geartronics recommendation. And CLS are not cheap.

The majority of the failures occur using budget open loop systems that are DIY fitted. A good CLS will actually reduce dog-to-dog clashes and thus wear.

There was from memory a powershift fitted to a BEC mini in one of the mags, I am sure they said £6K ( !!!!!!! ) for the system???????????????????????

Feck that o_0. I'm quite happy with paddle & cable on my Fury.

No, make that very happy; it works a treat and becomes very much part of the the whole gestalt of driving such a car: small, precise movements requiring both a very relaxed and forward-planning approach to driving the thing to best effect. Dainty, delicate movements; brutally rapid transport smile
