Audi 01E 6-speed

[Doger Karlstrom]

Does anyone know how mutch load the 01E 6-speed will take..
im thinking about the 01E with the wide and flexible 1 gear..

or should it be better to go with the porsche 944 turbo 5-speed gearbox?

hi Doger

take a look at this thread and the gearchart.xls within it.
For me the Audi 6 speeds are having ratios which are difficult ( to say the least)
Just check also some of the G50 threads.

From what I have gathered in my endless quest for information on AUDI based gearboxes, the O1E is based on the 083 944 turbo box. (which is a modified 016) It shares the slightly larger ring gear and front pinion bearing and has a wider 3rd gear. The later ones had a wider first gear.
One thing i haven't figured out is why they moved the differential cover to the opposite side. This now puts the differential load on the cover instead of the case. Maybe for ease of assembly?
The early O1e''s had a problem with pinion bearings and it seems to be the concensis that this was caused by improperly set preload at the factory. (although the factory hasn't admitted it)
The O1e should be comperable to the 944 turbo (083) outside of ratios. The 944 turbo (083) has been used successfully in many v8 powered 944's. One of which has an LS1 with a Magnason supercharger and over 500 lbs. ft. of torque at the rear wheels. This car is a part time track car with no transaxle problems. There is another with a highly modified Buick Grand National turbo v6 with just under 600 lbs. ft. of torque at the flywheel which also has no problems. This car isn't a track car. Neither of these guys do drag race starts but do drive hard. These are just two examples.
My pinion is that the O1e is stronger than the 016 but does not have good ratios.

I have checked the ratios..but one thing ,is realy
the tires 26,9inc (68,3cm)?
i have no tire to mesure it..but it is almost as large as my chevy silverado tires..=)..only a few centimeters will change the resultat dramticly
maby someone can mesure som tires to gett exact readings..or have you done that?

Take a look at this post
http://www.gt40s.com/forum/gt40-tec...wheels/24267-gt40-tirelist-mainly-15-a-2.html
for an updated tirelist.
In the gear ratio chart you can change the tiredimension if you want.
But still it will be not optimised ( first to short, sixth to long, just 4 usable gears. and than i would go for a 930)

I have checked..it doesent look nice..but i have stomble over diffrent ratios on the net..so i wonder what will be the right ones..
for example i found this ratios on another site??

[EGLITOM]

just put in the ratios into the gear ratio chart and check which one will fit

I think you missunderstand me..offcourse i know how to figure out with ratios will suit best..it is not that..what i mean is that the ratio that was in the cart you postad was 3:88
in the chart i posted it is 3:50 for the same gearbox

a huge diffrans..so i wonder what will be right..=)

 

[EGLITOM]

The gear box in my chart is from the 2,7TDI as of 2005. but some of your ratios above are similar. If you look close to my chart, you will see that the first gear is a 3.5 and the 3.88 you are talking about is the ring and pinion ratio. So don´t compare and interchange those two ratios

I have taked to a swedis gearbox rebuilder..
and he will build a 01E gearbox with this ratio for me..

Pinion ratio 4:11

1 gear:3.5 I think maby it is possible to have 3.3?
2 gear:1.88
3 gear:1.3
4 gear:1.034
5 gear:0.857,
6 gear:0.71

This is the chart how it will be with 275-55-15 wheels

1/3.5..39 Mph (3.3..41 Mph)
2/1.88........73 Mph
3/1.32......103 Mph
4/1.034....132 Mph
5/0.857....159 Mph
6/0.71......192 Mph

And they put a oilpump in the gearbox that spray oil on the pinon also..=)
and the first gear is uppdated from the -99 year wide flexibal gear

what do you think about this?

/Dogge

 

[andys]

Dogge,

The 4.11 ring and pinion ratio will make 1st gear quite short. If you have the option to employ the 3.75 ring and pinion, 1st gear would be more suitable, IMO. I am not aware that a 3.3:1 1st is available, but if it is then I would strongly suggest using it. Some years ago EuroSpecSport cataloged a 2.7:1 1st gear 01E option, but I understand it was dropped for lack of interest (imagine that!). Makes one wonder if some of those gearsets aren't laying around somewhere?

Ratiowise i would be ok for street use although first is still low. In my build thread i have a newer version of the gear ration chart. which also shows the RPM drop at each shift. may be you fill in your ratios there and check.

The AUDI gearbox has another drawback in my opionion. The position of the drive shafts is pretty low. So usually you have to mount the engine-trans combo a full inch higher than with a porsche or a zf. This in itself has several drawbacks:
higher point of gravity
less clearance towards rearclip for exhaust
less clearance towards window of rearclip for aircleaner
Of course it will work fine but it is just less optimal. BTW your transmissionbuilder will also ask for some money. my reco do a market research in parralel on G50´s and compare where you end up finaly

[Doger Karlstrom]

yes it is possible to find the 2.7 first gear..
then it look like this..

7000 rpm with 275-55-15 wheels

1/3.5..39 Mph (2.7..50 Mph)
2/1.88........73 Mph
3/1.32......103 Mph
4/1.034....132 Mph
5/0.857....159 Mph
6/0.71..192 Mph(0.73..187 Mph)

Peter Bailey use audi 01E on he´s racing cars with 450hk in it..
and as i can understand it he have won some races with that car..=)
so if the engine comes 1 inc higher up??..maby doesent madder that mutch?..
maby the pressure on the outside tyre is less and you lose grip..i dont know..=)
like when you need to lean to the wrong side when you drive a gocart..*lol*

The price for the fixed 01E is rather human i think..i will pay about 3500us for it.

 

[Larry]

I run a SBF, limited to 5500 rpm, in my BEC GT40. It has an 01e with a final drive of 3.875 with 295x50x15 rear tires. Here is the breakdown on my gearing if the engine is capable of 5500rpm:
Gear (ratio) Speed
1st (3.50) 32 mph
2nd (1.89) 60 mph
3rd (1.23) 91 mph
4th (.933) 120 mph
5th (.729) 154 mph
6th (.600) 187 mph

The 01E gearbox was/is an all new unit similar in design to the 016 but totally unrelated.

There are 2 versions of the 01E, a FWD unit and all wheel drive unit. Other than the mainshaft most internal parts are not interchangable.

The FWD unit has only 1 final drive of 3.85. If you use parts from the Porsche 968 gearbox, you can have a final drive of 3.44.

There are a few different gearsets that can be had one being the very tall TDI sets, a close ratio set and the Porsche 968 uses gear spacing that is in between.

Some of the AWD units had an oil pump which moved lubricant from the pinion sump to the radiator returning it to the rear center differential (no spray involved).

 

[Scott]

There are only 2 first and second gear ratios with the 26mm first gear available for the FWD 01E.

3.50 first and 1.89 Second or 3.75 first and 2.19 second.

The first and second gears are ground on the same shaft so you can't mix and match those gearsets. Any other 1-2 gear ratios aren't production factory offered.

The 968 gearbox utilizes a 3.1 first and a 2.0 second but it is the 22mm width first gear.

We've delivered 2 types of these gearboxes, a wide ratio and a close ratio version.

The wide ratio gearbox has the following ratios:

1st 3.5000
2nd 1.8890
3rd 1.2300
4th 0.8710
5th 0.6670
6th .5610 (Also .60)

The close ratio has the following:
1st 3.7500
2nd 2.1875
3rd 1.5200
4th 1.1724
5th 0.9697
6th 0.8286

As far as horsepower rating goes, I've got some gearboxes behind some pretty potent small blocks as well as a few V12's and none have failed to date.

The 944 and audi 5000 gearboxes are decent for modest horsepower. The biggest issue is the 5th gear that is unsupported at one end, and the thrusting surface is marginal, which can cause the input shaft to bend and either strip out the fifth gear or push the bearing/race through the center section. In this post is an example of one such occurance.

Scott,

How does this compare to the O1X?
