T5 gearbox

[IhateRICE!]

hey all

I just want to know how much power a T5 could take before it destroys itself. because i plan to stroke my 304 to a 355 estimate about 440 horse's with similar torque. think it could handle that??


Cheers

You can destroy one with a stock 5 litre if you continually launch hard. 355 and they would be marginal. I'd be looking for a 6sp conversion.

As above, T56 conversion. Do it once, do it right.

I blew 3 T5s with a stock 5L.

Exactly, do it once, do it right, TKO-600 without a doubt. T56's are over-rated.

You could build a T5 to handle it... just don't ask the cost.

If cars running 1000hp can't break them, they must be good

You could run 1000 hp in a gemini on the street with skinny tyres and not break a T5 , but also you could snap one in a stock V6 VQ on the track. Extreme example but the cars weight and the traction play a big part in driveline life. Near stock LS1's snap T56s and tailshafts and axels like they are going out of fashion on the track

I was talking about a track car.

Track cars.... we've broken 2 in the last 2 years behind a supercharged VY R8 track car. $12,000 later for a box that so far is going a lot stronger (from the US... bit cheaper then the $30,000 holinger conversion).

There is a T5 running behind a 383 twin turbo pulling 1500hp.

The TKO box is a better option for the fact it's 20kg lighter and costs less to strengthen.

Bah, just put an auto in it....Much less messing around.

the word "butterbox" comes to mind.

be done with it stick a supra box in it... toyota W58's can be mounted up to a 304 (hydraulic clutch however) and don't cost too much. i looked at a T56 when i had my ss and the cost of a used box alone was hefty.
