I was wondering what power levels the stock gearbox will handle?


Also how much would it cost to strengthen it.



Talking around 750whp.


Also are there other weak links that show face around this level?

 

As long as you can stay away from the dreaded misshift, the tranny will hold well over 1000hp. It's the torque that will kill it mostly. 3rd gear seems to break first. Mine is still bone stock. Knock on wood.

 

I do not know where the upper limit is. Wider square cut gears are available, but are noisy. Friction coating helps. You can install steel syncro's and last but not least a tranny cooler. Here are some pics of the cooler/pump on ours.

+1 on what CVJ said. A tranny cooler goes a long way towards prolonging the life on these cars especially if you track them or have an LSD which will add heat due to the friction of the clutch packs. I have a set up very similar to what CVJ runs. With over 30 track days on it, it's a proven set up. Details of the cooler are below.

You took yours a step farther with the auto thermostat. We manually activate.

 

oh boy here we go again...

 

My set up is totally hands off but I do have an override ON switch that I normally activate at the track prior to going out to get the oil circulating as opposed to waiting till it hits 200F. Other than that it's basically exactly the same set up.

 

CJV is right, I am deleting my comment……..it isn't worth the time…..

 

Wealth Manager, I have not been on the 996tt/GT2 forum much lately so I have not had a chance to view how some people interact. The fact the comment seemed to be ignored seems to indicate members take him with a grain of salt.

I would hope in the future Turkish understands how his comments are viewed and how it effects others. I would not lower yourself to back handed insults. It only tends to spiral downward. This is what the reporting of a post is for. Believe me, there are plenty of mods who will check it out and take action is warrented.

I truly hope this puts an end to this type of behavior and tension among perticipants.

 

Repeating someone else's eternal wisdom ...

Plenty of info on "Stock Gearbox Power Levels" in the search function............

 

i didnt get to see the o/t posts but i truly hope it doesnt deter you from posting on here cjv. i appreciate all the pictures, advice and knowledge you and others have posted here. im working on a build as we speak and have already saved myself from making some expensive or uneeded mods just from listening and watching. thanx again to all those willing to openly share their knowledge with me.
