Looking good! May have to consider a turbo swap myself soon if I keep my 957 long term. Not looking forward to the tuning though...

 

Looking good. I am excited to see you succeed. How will you do the tune? As I mentioned before, EVOMS told me that the ECU was the limiting factor and if you change for a different ECU, then you have to figure out how to make the engine and transmission work together and that will take a lot.

 

It is hard to say right now. The tuning will ultimatly be the limiting factor. Based on my research only the syvecs is flexible enough to completely replace the ecu as a standalone. The Cayenne really set new standards for Porsche in the CAN messaging dept. It was very advanced for its time. Capturing, decoding, and figuring out the algorithims to these messages is really wherein the challenge lies to integrating a standalone as a piggyback or using as a full replacement.

In the case of standalone as a piggyback:
It is hard to say how certain systems will be affected with the loss of control by other systems when used as a piggyback and what can be done about that with programming of the stock me7, programming the standalone, or a combination of the two, is really hard to say without a working build.

While me7 has some limitations it is still very powerfull. Im confident it can be tuned to at least around 800chp and be very very good. The Audi and vw guys even have some als and 2 step coding figured out, not to mention different modes such as APR's tune for the Cayenne which I dont feel gets enough credit.

Proefi 128 might work but thats a large outlay for experimenting, IF maybe say D3PE would take it. Like you said, a lot of people want to close the door in your face when you say Cayenne. Which blows my mind because @ this point if you can pick up a clean turbo and throw another 25k or so at it, you could come out with an awd tt v8 beast with about 1100 hp for less than 40k. I feel like with the age and drop in value on these amazing vehicles there is a whole market reopening for performance parts, replacement/salvage parts, engines, REAL tuning options, and a REAL turbo upgrade option. Just wait till the hot rod guys figure out they can pick up a used 4.5 tt engine for under 2500 bucks and run that standalone, because they dont need the rest of the car to work, only the engine. Like WOW!

As far as Syvecs go's you would have to invest in the install, and then probably fly in Ryan G. Or something, rent a dyno, and start tuning/developing. Theres no way to know where that could go financially all said and done. It would depend on how much could be worked out before that plane ticket go's out to Ryan. This is the second most expensive option with likely a high success ratio behind Motec, which I feel is not an option based on cost.

Im hoping the VE tables arent off too much for me on startup and really shouldnt be as I havent changed the cams, ports(much!) Or displacement much (its only .040 over). Stock .6 bar boost is around 9 pounds so il try to set it around 5 or 6 and hopefully it will run well enough to get the rest of the car completely sorted out. Then I can start doing some serious talking and making some decisions about whether I want to invest anything into the me7 ecu or just go for a syvecs standalone, or try the proefi as a piggyback.

 

That was what I was thinking when I got my CTTS. Someone should be able to modify it for $20-$30k and end up with 800-1,000hp. I posted that question in another thread. That is when you started giving me advice. (I Requested advice).

I am confident that if you can figure out a package like that, you would create a market for it and make some money. A $50,000 5 seater with 1,000 hp!

 

The problem is that once you put out a kit, or a set of headers, and make this stuff available to everyone especially if its going to be a bolt on affair, is that you have no protection for your intellectual property. It Becomes more of a game of who can come out with it first, who can sell the most the quickest before your intellectual property and all the hard work is stolen. That takes a name, investment capital, and a customer base. And its hardly a long term producer unless you can corner the market somehow. Easier said than done and I'm not looking to start a buisness solely based on the Cayenne. Then you have guys like the heckler on TTvipers thread that just cant understand the concept of doing something like this and only want to keep up with the trends by having the latest and greatest every year. Its takes a special person to want to mod a CTT and the numbers just aren't there yet. I have thought about the profitibility part of this venture especially if Im the first in the world with over 800hp or so and that should be enough to go over the current 199? record set by techart with 680hp? But at the end of the day I just want to enjoy MY special ride and I'm not doing it for bragging rights which Is why I have not and probably will not post a build thread, and if I do it will be on a different platform that I have more control of other than the forums . Although I am open to sharing the general overview of my experience and if someone comes along and is serious I have no problem sharing what I have learned.

 

It seems that the safest way would be to make a deal with a know tuner like EVOMS or Fabspeed for example. Use their higher profile to sell the package. You get something for each package that they sell plus you sell them the exhaust manifold or whatever else you can produce that they can't go around you on.

Or if you like to build them, build one and sell it. Then build another one and sell it. That way it is part time and doesn't effect your daily job.

 

All anybody has to do is buy my manifold and build jig to reproduce them. I personally think the security lies in the tuning/standalone and a plug and play harness/ base file. Heck, truth is if anybody was interested they could just get a Cayenne and do it themselves but they wont because their not.

 

Copying any of that wouldn't be too hard these days. I don't think there's a ton of interest right now because these things are pretty quick stock and folks haven't been too keen on spending another $20k on top of what they already paid for one.


I do agree that I think you'll start seeing the motor popping up in the odd hot-rod before long. I also think eventually someone will build one up over 1,000hp just because they can. Hell if yours turns out to be very far north of 800 and there is potential for more with more tuning, folks might start getting more interested.

 

Oh the joys of CR. How was the food? Casino? I have crossed a few of those rivers and almost got stuck on the beach just south of Jaco(playa hermosa).

 

what do you guys think of HHR?

I've been looking around and came across them when i was doing research on the fabspeed secondary cat bypass

It's a quality system. The only downside I had was not getting tips with the system. I ordered a 3" set and made them work to keep it 3" from the turbos back. I would not hesitate to use Hank again.

 

+1 on Hank. Great product at a fair price. I have the secondary bypass pipes.

 

I have had the secondary cat bypass, midpipe, and muffler from HHR for a couple of months and just ordered the primary cat bypass about an hour ago. Great sound!

 

This is what you get from Hank.

 

Cat deletes.
