Roll Call - 996 Tiptronic Owners
I am just basing this on the k24/18g dynos i have seen, very linear.
The only 16G dyno i have seen is the AMS Billet 16 which shows crazy torque at very early RPMs.
Is it horsepower or torque that kills the tranny? Does anyone know the actual issue with the tranny? Is it the overheating? The 3rd gear clutch pack? Combination?
Can you explain tuning out the torque? If torque is the tranny killer, dialing that back to safe levels (trial and error), seems like a good way to go.

OK. The Billet K16 is NOT a 16g. 2 VERY different turbos. The billet K16 (regardless of who's it is) is very new technolongy. The 16g is 15-20year old technolgy. YOu will notfind anyone with 16g's making the kind of power and TQ a Billet K16 does.
Tuning out TQ is done all the time, especially with stock bottom end cars. You typically make the most TQ at the end of spool. This can be done with boost, timing or both. With these cars (with stock equipment), you can control how boost comes in and you can retard timing on the TQ ramp to keep it at safe levels. This changes some as you get into bigger turbos as you make more power with less boost because you have more VOLUME of air and fuel to make the same power...
I have heard from many people that with the tip, you can not even run 18g's at full boost without running into tranny trouble; a couple good runs on a 20g and the tranny is toast....how are you able to run the GT30's without a problem? What boost are you running it at? Have you ran race gas yet?
Thanks!

Here os a Dyno printout with only a Revo Stage 1 program & standard exhaust & cats with a K&N panel filter.
Since then I have had a 100 cell Miltek motorsport exhaust and stage 2 Revo.
Torque might not be up much more but BHP is estimated to be another 7% on top of Revo1 tune plus another 15 to 20 for the exhaust & cats.
Please note the figures are SBHP and do not allow for TC slip.

Good point. Heat kills ATF fluid. With increased power = increased heat. For hard driving, I'd say even change the fluid with every oil change.
Are their any oil coolers available to enhance the tip's cooling ability?
I have changed my ATF fluid several times and the car has less than 35k miles. I had a gasket leaking, so I would constantly add ATF fluid until I eventually had the tranny rebuilt (it takes only a couple more hours to repair clutch packs etc... if you are going to change the gaskets inside the tranny).
Below is a list of Tips that have upgraded turbos beyond the k16.
VividRacingTx - K24/18g - a road course is what destroyed his tranny
996TTalot - K24/20g, tranny destroyed after just a few dyno runs
Waymegelli - GT30 - not fully installed yet
MY996TT - GT660 package - no problems at all
007-911 - GT28 - no problems
Are we missing any other no K16 tiptronic?
By the looks of it, the Garrett turbos haven't caused problems...maybe i shouldn't install the k24/18gs next week lol

there are some companies who make this but i don't remember the names.
So I talked to the dude who can rebuild these tranny to stock (works at a mb dealership in cali).
I mentioned to him that the sl65 uses the same tranny and puts out a ton of torque, and he said one difference between porsche and mb is that on the sl65 the throttle is left off between right as it shifts; Porsche's never release the throttle between shifts, which hurts the tranny with high hsp.
He also mentioned that when he rebuilds the clutch packs, the 3rd gear has a many packs that can fit. Porsche already maxs out the tranny. You really have to go to one of those Europe shops to get it stronger ($$$$)

Check out this post from Switzer...I wonder if they do it in house or outsource to MKB...

Switzer essentially does the same thing MKB does...Maybe switzer's price could come done since the euro plummeted
I plan on waiting until my tranny gets messed up and then I will pursue one of these routes (along with some really big turbos
)

I'm only on k16's as well ( for now), although I think some damage was started when it was on the dyno as its 3rd gear that is used for all the pulls.
