Can the new turbos be fitted into the 996tt, and if they can, will it be a meaningful upgrade?

 

Why would you do that? If you are going to the expense to change turbo's you can get a whole lot more peformance than the 997tt turbos.

 

That about sums it up.

 

not to mention that they r probably hard to get if even impossible....
they considerably larger then the 996tts from what I was told.

 

Plus, the variable pitch has to be controlled by something? Is it computer controlled or controlled by turbo RPM's?

 

It will be interesting to see how far the tuners will be able to take these turbos. I read in GT Purely Porsche they will be pushing 1.2 bar in OEM setup. I think the technology is excellent. Imagine applying it to some big turbos - GT40's that could perform like K16's off the line.

 

I think that upgrades beyond anything that the stock turbo can handle will be an issue. Where will you get upgraded variable vane turbos? Time will tell.

 

I would very much consider doing that upgrade as soon as GIAC or Pro-
tomotive tunes a 996tt chip for that turbo's behavior. I assume the maps
would look like a blend of the k16 and k24.... The big value over a stock
k16 would be at the top end, and compared to the k24 it would give less
lag. Sure, if top HP numbers are what you're after, there are already
more powerful options, but if you want real-world power under the curve
minimizing lag, this new unit will be a significant step up I think.

Wow, 1.2 bars? Hmm, if the 996TT was pushing 1.2bars on the stock turbos, it would be rated over 500hp I do believe. It would be close. I wonder how large the turbos actually are...

Another point: that turbo setup produces A LOT of heat. It makes me wonder how much more you could push the stock setup (can you get it to 1.4 or 1.5 bar), how large the fuel injectors are (very important for raising boost), etc...

 

There's just no solid information about the 997 turbo available. The intercooler size is still a mystery but at least the ducts appear to be large enough to push more air into them.

 

03-turbo911,

The duct intake is really an illusion in the 996tt. If you think the 996tt duct openings are small then you ought to look at the passage over the rear wheels.

 

cjv,

I hope that it got bigger for the 997 turbo.

 

The turbo technology is nothing new guys. These types of turbos have been around for a very long time.

The issue with back dating the 997TT turbos to the 996 will be the control. As it stands the control is done by the ECU so how does one control them? It would have to be a standalone system in order to control them. You can not add another map to the existing ECU which in turn has no GPO to feed the harness anyway. There are many facets to the control and function of these turbos

It can be done and has been, it will just not be as easy as a flash and turbo swap.

 

Crap.
Thanks Stephen.

 

Stephen, this turbo system is known for making incredible heat, correct? This is why it hasn't been used very often over the years? Wouldn't upping the boost on these turbos make things very interesting in terms of both efficiency and the metal's durability?
