Suman,

Who are the other mystery tuners for Porsches (Bosch code)?

FAb work is not an object. We did out own custom ICs... headers and intake stuff is easy... exhaust is a joke. But intill someone comes up with a viable hands on tuning medium we are still obligated to go with epensive tuning kits.
Fishey,
what is ur solution.. have u ever tried.... a after market MAF for high HP 996tts?

Fishey, while it may be less expensive for us to do all of the work on our own cars, for some of us, the time spent doing that work could have been spent making enough money to pay someone 5 times to do the work.

If I spent all of my time working on all of my cars, I wouldn't be able to make any money to afford them. I guess it's a trade off.

 

Of course there are other Motronic tuners, not evey tuner is on internet boards.

I like Fishey's approach but it sounds to me like he is a bit old school, back at the time when these cars were not as electronically sophisticated.

The only two reasons one would run a standalone system vs a Motronic on these cars is if he cannot tune himself Motronic or if he is racing (therefore always uses the same race fuel--knock safety) and needs the flexibility to modify maps on the spot.

A Standalone will not have knock sensors (even Motec are not as good) and therefore you will end up either compromising on performance due to your forced margin of safety needed (timing, fuel and boost), or blowing up your engine the day you fill different fuel under certain weather conditions.

On a 930 that has no electronic gizmos (PSM, ABS, etc) and protection, it is a no brainer as an economic solution to tuning. With Garrett having all the maps published and available, choice of turbos, I/C and other become all easier. These bolt-on GT28s seem to be a good option.

Nowadays with the flahloaders and similar options that most of the tuners provide their customers, you have great flexibility for street/performance cars.

 

Spot on Jean.

That is why I memtioned "time frame" as in what year above. I have a tremendeous amount of respect for people like Big Ben and others who do their own work. It is like black and white............... just alot of grey in between.

Go back a five years and these motor were in their infantcy. Go back ten years and the Le Mans winning GT1 had 600 hp. In 2001 500 rwhp was a milestone for these motors on the street. If these are such simple packages just try to disconnect the throttle body shutdown. Or as Todd @ Protomotive recently did, transplant the GT3 program on a 996tt so it can read (and start) a motor that has a cam with GT3 pointers on it. I could go on. For those who don't know, I would love to show you a print out of the 996tt ecu program and ask you to identify certain parts. The TB shutdown for instance. Good luck in identifying it. This is where people like Todd @ Protomotive and Garrett @ GIAC have it above 99.9% of the rest of us. Even they can't identify and answer all my questions.

Fishey is correct to a point. Today, more people can go farther wth tuning than they could have in let's say 2002. This is progress that has been hard won due to the efforts of some of us. Yes, the costs are still high in relation to other motors .............. but no where near as high as they were for what you get a la five years ago.

 

HOW ABOUT LARGER TURBOS... GT 30 OR GT 35s??

 

robmd99 - markski is running GT35R's. I am done waiting for Tial. Starting next week we will be installing our custom ECU. Once that is tuned and dialed, we already have the injectors, fuel pumps, billet fuel rails, and IC parts. We will then do a GT28 with short adapter to fit with stock Porsche headers and exhaust. Stay tuned, this will happen from Vivid!

 

Good luck and I wish you the best!

Hi,
Any updates.

 

I'm no expert by any means, but these broad sweeping claims of bolt on and turnkey performance enhancements with no supporting data, testing, or confirmation by someone who has BTDT..... is a little disturbing, maybe a bit misleading if not just a tad bit irresponsible.

 

Making a turbo kit for a car is not brain science, if you want to throw thousands of extra dollars at a Brand name tuning shop that is fine, but make no mistake these companies are charging more than a premium for the work they do... I have built many honda motors, I am currently building a 2jzgte vvti motor, and I also own a 996tt. A motor is a motor is a motor, any good mechanic will tell you this and if vivid can supply a BOLT ON TURBO Kit for less money than other tuners well then I commend them for supplying pcar enthusiasts with an alternative. If you do not know exactly what a bolt on turbo kit consists of and how easy it really is to install and tune assuming you have a form of engine management, a wideband 02, and a dyno then you shouldnt even be reading on a car modification forum. I mean if greddy, hks, etc can supply twin turbo kits from 5-10k, then why cant a pcar tuner supply one for 15-20k. 28k+ for a Bolt on turbo kit is absolutely absurd, if you price out the parts you need and do a little bit of homework you will understand how badly you are getting ROBBED. Good luck to Dan and Vividracing!

 

You even sound like a Sooner. Nice excuse.

 

Grett: Looks like I must have hit a nerve in the root canal. My point is not that you, or anyone else for that matter..... don't have experience, or expertise, or mechanical ability. It's not that you might not be able to produce something that might work for less money than the market currently gets.....my point is advertising something and putting out specs or so-called facts and figures with no dyno or tests or backup documentation of any sort.

If you manufacture a product and want to market it to a large audience, I would expect that you go through an appropriate amount of scientific testing in order to be able to assure any potential buyer that you were'nt just pulling stats out of your *** or making broad sweeping statements without any recognized and accepted engineering practices. You will have to admit that there are a lot of products on the market right now that make claims of increased horsepower, hotter spark, better gas mileage, better performance etc....and they don't do anything more than take a chunk out of your Visa card.

My point isn't that you or anyone else don't have the ability to come up with something new and neat....my point is that you cant' just throw out wild claims without some sort of proof and assurance that we're buying something that will work as advertised, and won't adversly affect our cars. As consumers, I think we have a right to see proof of product performance before we but it, and simply asking for that proof shouldn't **** off a manufacturer or vendor.

 

The fact is prices are driven by supply and demand, not by profit margins or what is "reasonable". Currently the supply / demand curve dictates that 996tt owners spend a ****load of money on modifications. If people want that to change, they either need increased supply (such as Vivid and hopefully others in the future) or decreased demand. If people refused to pay the prices these tuners ask, they would have to sell the mods cheaper or get out of the business all together.

 

I have no quarrel with the supply and demand issue....I have no quarrel with any manufacturer or retailer coming out with a more reasonable set of headers, turbos, mufflers, or any other bolt on performance part....as long as they don't make broad, sweeping, and unsupported statements about the performance potential of a product without being able to back it up with some sort of substantiation.

I'm no different that any other Porsche afficianado...I'd love to see a really nice set of proved performance headers or an exhaust system for $1800. But a lot of the stuff that's hitting the market recently is coming from outsourced companies...mostly China and Taiwan....and I have yet to see performance statistics or dyno sheets on a lot of it. That's not to say that it might not be up to par with products we're currently paying $3K and more for, and we'd all love to see more reasonable prices....but the products we've seen here in the US for some time haves a history and performance stats (some good/some not so good) behind them. A lot of this new stuff has hype and that's about it.
