Hi All,

I just saw this in the Fisher Sportscars website, regarding the Fisher Fury Fireblade: "There is no need to use the clutch on up changes, just lift off and snap change."

Do you guys do that at all??? Is it something I'd like to do???

Cheers,

Alex

yes i did this all the time in my XR3 right up untill i needed a new gear box

you can change gear just as fast with the clutch anyway

I certainly do it all the time, particularly when "going for it".
When you're about to change gear, just put some light pressure on the gearchange in the change-up direction. Then to change up just lift off the throttle for a tiny amount of time (before flooring it again) and it will slot fantastically quickly into the next gear up.

It's certainly the fastest gearchange I've ever used/had/done in a car

Cheers,
Ben

Perhaps this link will help...

This is talking about sequential boxes in a racing car, but the internal mechanism is much the same as on a bike.

I've done this on a bike going up the gears, but I really don't fancy doing it on the way down!

alex, the clutch is totaly redundent on up changes, just ease of the throttle n pull.

And man it feels sooooo good - even my dad's getting the hang of it - now just got to get him to heal and toe on the way down or I'll be looking at another gearbox again!

BTW - last track day I did there was a Megabusa with a turbo charger (beautifully installed) AND Nitros - he is either mad or has very large kahones (Alez - please help with the spelling there).....

Having a more natural feeling (for me anyway) pull-to-go-up gearchange, I dread ever being offered a drive in a BEC with a push-to-go-up change, I bet within 3 laps I would have buzzed the engine!

Regarding clutchless upchanges, yep I do it when I think about it, although natural reaction is still to plant the left foot to use the clutch.

I've gone the push to go up root as it seemed more logical. Plus i reckon it feels easier/quicker to go down a few gears using your fingers to pull rather than pushing using your arm.

My cars not on the road yet, so WTF do i know

you can let me have a go in yours then now to get some practice in before mine is finished!!

A mate of mine has a fury thing and hes just changed his to push for up because his gear change on his Audi works that way, so I dont think it can be as unusual as you think, the only thing is now I dont know which way to do mine because Im sure we will drive each others cars.

I chose the opposite as it seemed more natural to me at the time, though in hindsight wish I'd done it the normal way 'cos I'm likely to buzz an engine in the manner you describe if I ever drive a different seq-shift car.
I could change it in my car and "re-train" myself, but I fear I would probably need a good supply of engines standing by while I got used to it

How about changing it around, and fitting a rev limiter?

'cos when you're doing 12500rpm and you change down instead of up, a rev-limiter isn't going to help much!!!

Cheers guys!

Good stuff, I thought it may be OK for up shifts and actually I used to do it all the time with my motorbikes (even down shift sometimes, I have to admit).

Pulling for gear up feels more natural to me as well: When you do up shift you are usually accelerating, so the new gear will pull your body if you know what I mean (excuse my English). When you do down shift you are usually deccelerating, so when you release the clutch your body with be pushed forward.

Jasper, pronunciation probably the same, spelled "COJONES"

Cheers,

Alex

David,

Excellent article about gear changing, really.

regarding the gear changing, I know Ian Gray does (did?) usually fit them as a push-to-go-up

Some semi-auto cars use a push-to-go-up tho, such as the Smart.

With a bike engine, you should be able to go up and down the box without the clutch - though down will take a bit more practice (NOTE - most bike manufacturers say in their owners manuals that the g/box isn't designed for clutchless changes).

For those of who are really keen to go up the box asap, get an electronic cut out fitted - it saves closing the throttle, just cuts a couple of sparks!!

Ben, the Fluke one is probably better quality carbon (pre-preg) but it doesnt have the same shape as the Plays-Kool one, it just does straight across and so leaves the sides of the scuttle unfinished, if thats a concern to you.

Chris

Or buy a piece of carbon and make you're own!

Doesnt have a rolled lower edge if you do that - SVA issues if you havent already passed

Here in Aus, most of the cars available with sequential semi-autos have push to go up, and the only one I know of that uses the other way is the Ford Falcon T series.
