Is it still t-50 ?

[damusto]

Hi Guys
I need help with gearbox identification.

The gear set looks like this:

1) 26/16 x 26/18 [2.347:1]
2) 24/20 x 26/18 [1.733:1]
3) 21/22 x 26/18 [1.379:1]
4) 19/24 x 26/18 [1.144:1]
5) 18/26 x 26/18 [1.000:1]
R) 17/14 x 33/17 x 26/18 [3.405:1]

My question, is it still t-50 or maybe some other high-performance model ?
My investigation shows that this is just addon set to t-50 from British manufacturer Quaife - Could You please confirm ?

it is the dog box for rally/race car, not for a street car

[Uzelac]

Great ratios!

[damusto]

Thanks for the quick response, but I need to ask for more precise answer.
In other words is this "dog box for rally/race car"still t-50 ?
Or is this variant signed in quite different way ?

[Project D]

It is A T50 casing, but all the internal are replaced with straight cut gears.

[damusto]

OK thanks Mate

Now I wonder, do we know the max torque(and at what rpm) will this box handle ?

[rene]

it run on needel bearings so 10k but center line between axels are stille satandard so around 250hk it is safe for a 1600ccm NA

Ok thanks.
I have two more requests:
1) Could You please give me math formula to convert hk to nm
2) Where do You get this information ? Maybe You have some sort of service manual ? Because my is very poor when it comes to such data.

Rene are U still with us ?
I read TRD SE Bible and Toyotas SM, I found very,very little there on this topic. That's why I'm asking if there are any other items ?

Heading back to the hk unit, I found several different mathematical formulas:

- hk=(nm*rpm*Pi)/30000*1.36
- hk=(nm*rpm)/5252
- hk=kw*1.36

It looks quite inconsistent for me, probably I dont know something about it.
All websides were in foreign languages ​​to me. I suspect that maybe "hk" is referred to the power unit - Is that correct ? Swedish maybe ?

If it was in Swedish then yes HK (Hästkrafter) is HP (Horsepower).
