Sequential Gearbox

[ciscotex]

I'm curious about the make of the gearbox, Wolfgang. It really appears elegant. What is the torque capacity?

Thanks in advance,
Paul

I would also like to know more information about the box. Do tell!

As for "period-correct" historic racing, there will always be a legitimate debate about where to draw the line. If we really wanted to stick to the period, we would outlaw synthetic lubricants, modern brake pad and tire compounds, non-points-type distributors, and ultra-high octane fuels. I'm not suggesting that I believe a 6-speed sequential box in within the spirit of vintage racing, just suggesting that like most things, there is plenty of room for debate.

hello guys,

first of all, i know that there will be at least to groups. some persons who do not accept such things in vintage cars and the others who maybe find it "cool" etc.

my car is not a "period correct" race car like a gta etc. it´s only a 1300 equipped with many fast and many modern parts like twin spark engine, modern seats, brake, suspension, carbon body parts, injection etc. etc. and maybe soon with a sequential gearbox. and why?? because its a horny feeling to drive such a fast old car on street or racetrack, hear the sound, feel the speed. and its very nice to battle with gt3, m3´s, corvettes, nissans and, and, ... on open trackdays. otherwise there are a few race series in germany or austria, where such modified cars are allowed. ( scuderia alfa corse, histo-cup etc.) there you battle with other modified alfas or with modified bmw 2002 with the old 2,5l m3 engine, opel kadetts, ford escorts, porsche 911/924 and so on
next season i will inscribe me in this two series.

now som technical details: this is a "dog ring box" (this means no synchro rings) the construction is lika a motorcycle gearbox. the maximum torque is 300-350 newton/meter. the input shaft is built with the same diameter like the alfa shaft, so i don´t have to change the clutch, when changing gearbox. only an other driveshaft and i can switch from normal to sequential gearbox, if it is needed.

the gear transmission ratio is with a bit longer first gear than standard, and a 0,85 6. gear almost like standard, so the gears 2, 3, 4, 5 are rather short.

the blue cable is for the reverse gear, which you shift with the second lever on the gear stick.

the bellhousing is a standard alfa part which is black eloxated. it is fixed on a milled adapter plate.

The reason I'm so against the non-period modifications is it ruins the car, deters others from joining in and is the complete opposite of what historic racing should be about, ie: the car ONLY, not the driver

Wolfgang,

Very interesting indeed. I particularly like the fact that you say the sequential gearbox can be exchanged for a standard gearbox with just a change of propshaft.

Now for the real question .... who makes this gearbox and what is the model number?

Alex.

[alfazagato]

That's the real question Alex...... I get the feeling that you have its inclusion at the back of your mind!!!!

I wouldn't bugger about with my car like that, but it might make for an interesting addition to a no-nonsense twin spark replica. Oddly enough, this morning someone actually offered me a 1300 GT Junior and a garage full of used spares for pocket money. Hmm.

[alfazagato]

I wouldn't suggest you muck about with your car its far too nice but, as you say, used in a pocket-money little number, might just keep a smile on your face over the winter! Bet you its not cheap!
How about that lunch we promised ourselves. PM me and we can agree dates.

It Looks exactly like the Gearbox from the Westfield S2000. I've tested one of those, and it used the Elite 6 speed sequential box . . .

Pete, Its lovely to see your famous Australian fair mindedness becoming bogged down on this subject. Fair doos if the car is a real GTA.... don't touch it...but if it is a clunker bought for "pocket-money" why not? I don't for one minute think that the intention is to build a stealth GTA or even a stealth step nose....so why can't Wolfgang spend a bit of money and have some fun on the roads.
I do think we have to lighten up on this matter.

And this is especially true when the race car isn't historically significant. For example, my step-nose race car isn't a GTA, and it wasn't even made into a race car until the late 80's. No history here. My series rules wouldn't allow the 6-speed sequential box, of course. But if they did, and if my competitors are allowed the same, I don't see why anyone else cares? In that case, it is even an entirely reversible procedure. And we aren't talking about original CanAm cars here! As for brake pads, I disagree with your assessment that modern pad materials aren't changing performance. They most certainly allow better modulation of braking performance, which improves lap times. They also handle high temps better, preventing fade. If they weren't better, no one would use them. The "period correct" argument would be that the cars should be raced as they were "in the day". Sorry for being an "agitant"! Erik
