My original response is in remembering what experts (who do k16 tuning for a living)
have said. Maybe we can tempt Kevin or others to comment... You might assume that
the competition and drive of/between Porsche tuners would have had them already
offering such programs... There has to be a very good reason why they all stop at 1.0...

 

X2, runs great with EPL flash.

 

So we'll see what happens ?

There is far more to gain with a turbo upgrade then running 1.2+ on a K16. There are many company's upgrading the K16 with bigger wheels that work well and are cheap enough that some one who can afford the car purchase easily. Install is a breeze too.

 

I agree but with what you have to work with, I'm determined to show the difference!!

 

Here are somethings to ponder. In order to get that boost you will need to spin those K16's much faster, pushing that wheel right out of its efficiency. The intercooler can only do so much and hot air in less dense and mucks less power. If that's not enough to kill the power think about this, all that hot air is going to make the DME pull back your timing to a point that you would make more power at 1 bar. I feel its a waste to even try it. Not sure if you are flashed but the stock tune will not let you run that boost any way. I am not sure but I think most tuners will not let a k16 flash boost higher then 1 bar with out some of the factory safety measures kick in and protect the motor. Now if you are trying to prove a point a flash is no longer a "stock" car so bolt on the turbos and don't look back. If I am not mistaken there are some board sponsors that can get you to 500hp fairly cheap.

 

+1 you're boosting well past the efficiency zone of the stock k16s and creating a lot of extra heat which causes your ECU to pull timing which kills power. All of this uses more fuel, creates more heat and wear and tear on your engine and you're left with very little, if any, additional power. If you add large aftermarket ic , with stock k16s, you're spending your money in the wrong place. I'd stick to 1.1 bar with stock k16s, anymore than that and it's really just busy work for your turbos.

 

This is the first time that I am hearing this. Some time ago I have ask here if the k16 can go to 1.2bar and everybody told me that is not possible, maybe EPL can explain what is the deal with the k16 and the max pressure that they can hold.

First, I have no agenda here and I just purchased a stock 996TT. I'm just trying to figure out the first few steps I want to take before adding turbos.

With that said, I understand the extra heat and well we all know heat will kill a motor or kill HP/TQ numbers. Here are my thoughts and maybe this will help show why I thinking the way I am.

Thoughts are based off using the car as a street car, your casual mash the pedal street fun car, if you may. So, no plans for riding the car out hard to allow the turbos to continue to stain and create constant heat.

Also based off the aforementioned, I’m thinking of installs that will benefit the end state not necessarily the first few steps I would like to go through with the car. Has me thinking I will plan on adding a free flowing exhaust, intercoolers, air filter with injectors, and flashing to 1.2 or 1.3 bar. Basically be ready to slap on turbos with a retune once I figure out which turbos I want to go with but in the mean time it feel similar to the last 996TT I had. Again, I am thinking of pushing the boost a bit on the stock K16s giving me some time to figure out what turbos I would like to go with.

Cheers,
Allen

 

You will have to retune with new turbos anyway...do a basic K16 flash for now and save all your parts and do everything at once INCLUDING the turbos. You and your wallet will be much happier...

 

My tunes will be delivered at no cost and I do plan on doing a basic flash but want it to deliver 1.3 bar with the basic flash on the stock 16s.

The few mods (exhaust, intercoolers, DVs, ect ect...) I will be doing myself, so no labor costs there.

 

Do inlets pipes as well, now you've just recovered ~.2 bar of pressure drop in front of the turbos. Staying with stock K16s isn't the cheapest way to more power, but there are ways...

Too many variables to put a blanket cap on how much boost a turbo can support/stop making power at. If you've got a a lower restriction inlet system, good intercoolers, exhaust, etc that's way different than a 1 bar flash on a stock car. Bang for the buck isn't really there of course

I don't know any tuner on this forum that would (in good concience) give you a 1.3bar file for a stock K16 car. However, it's clear you know what you want and what you're doing, so there's no point in anyone else here trying to explain that you will likely be making less power at 1.3bar than you will at 1.0bar, so good Luck...keep us posted...
