Gearboxes for 5++ hp

[volcano rs]

so whats the story with kv engined coupe quattro boxes around 1986 ? from what i've heard they can handle some series power .

[~Delta]

You heard right dude, they are tough.
I proved it in my type 85 Coupe quattro (1987)

[volcano rs]

so delta tell me more i gave one of them away thinking it was scrap but i can get hold of one what exact year or part number i'm i looking for . respect .

[~Delta]

Coupe quattro 1987, code "US".

[volcano rs]

aren't they torsen in 1987 ?

[~Delta]

No Torsen in type 85 cars, apart from quattro turbo 10V (MB) and 20V (RR). Final drive on those cars though are 3.89:1, so no good for S2, unless you replace the rear differential with one from the Ur quattro.

016 transmission with Torsen and similar overall gearing as the S2 (4.11:1 and 24.7 MPH / 1000 RPM is the one fitted to Audi 100 quattro turbo (type 44 from 1988 - 1991)

Got a 5.5 mb vid clip of Audi 90 (4000) quattro doing 10.07 1/4 with that box.
Want to see it pm me with e-mail cos got no idea how to upload it onto here... lol. Worth seeing though!

dont tell anybody

But for the 6 gear boxes, is it most important to get a box with a wide and flexible 1st gear? Or will the flexible dont be any stronger then the normal wide gear?

[Henka]

First thing is a wide gear, the flexible shafts are secondary.

I'm kind of leaning towards a 016 locker for a future project. However, I'd like to try a car with 300-ish hp, a locked center and decent suspension before I make up my mind.

Also, once again.. The link that I posted - it's REALLY worth looking at. That is one useful page, lads!

[Erikb]

I looked into that one, it is really interesting site. There are so many different gearboxes. I really like to have a 6 speed box. But it must be capable of taking some serious abuse.

But what about the installation, are all boxes easy to install?

Thanx,

Erik

@Henka

What is the Gearbox Letters for the A8 gearbox? Is it with torsen and a straight fit? Do you have this info?

As I stated in my previous post - its DGV. Torsen, straight fit if you have a car with a 01E, you'll need the linkage parts from the S2 though. They are cheaper than Rs2's and S4/RS4's at least in Sweden.

I personally think you are wrong. You are wrong in the sense that the application decides what gearbox you need.

The gearboxes with the wide firstgear has a weaker inputshaft. This gearbox should be good for dragracing with a medium powered engine.

The gearboxes with the narrow firstgear has a stronger inputshaft and is therefor more suited for highpower engines used on trackracing.

For pure dragstrip performance the old 6E 5 speed gearbox type 81 1983-85 is the probably the strongest and best ratios for this purpose.

6E? Is that FWD or 4WD? I suspect that it's FWD...

I always thought they were the same size. I mean, there is nothing that suggest that it HAD to thinner/weaker due to a wider gear. Does this apply to all gearboxes with a wide gear, flexible axle or not? If so, I see your point as track cars don't generally use first gear and max power output. Anywho, still tempted by the locker though.
