Well T-P-P was develop one of the few Boxster kit that didn't blow up the motor:
And TPC Blew a Couple
Renn Team Forum:
Do not, I repeat, do not think about inbstaling a turbo/supercharger on your car. I made that mistake & I ended up with a blown engine one month after instaling the kit. Based on my experiance the pros & cons of the upgrade:
Rennteam.com Forum
Pros:
1. The look on the face of the people when they realise that a boxster is pulling ahead of their much powerful cars.
2. Strangely enough, the extra heat from the kit was not a problem even though I live in a country with hot climate.
3. Nothing else.

Cons:
1. Blown engine one month after instaling the TPC supercharger kit.
2. Oil leaks developed as soon as I installed the kit due to the extra pressure on the engine.
3. The supercharger noise is much lowder that the music that is coming from the flat 6 engine.
4. The perfect ballance and drivebility of the car was destroyed by the supercharger kit. Basicaly the car became a nightmare to drive on a daily bases.

Prior to the supercharger nightmare I installed a TechArt kit that included a sport exhaust, reprogrammed ecu and an air filter. It was ok, nothing more.

I learned my lesson the hard way . A porsche will always be at its best when left in stock form. I am about to purchase a new porsche and I will keep it the way it is. You have to understand that tuners are not best, smarter or have more resources than Porsche, they just have different priorities. The tuner goal is power at the expense of everything else, while Porsche gives you the best allround package that includes reliability, drivebility, performance & confort.

You have an excellent car, please keep it this way.
ple of 986 that was just after a month of install:

All Box Specs are na right? Those SC kits would tear up the field.

Correct! and I have seen most of the early TPC kits blow up the engines

ME;
There is more of them I know but you have to Digg!!!!!

I am not trying to start a fight or anything but that the different between 10k and 20k reaibility. I know I pointed out the 986 but rather pay Ruf the premium for there kits,wHy because they give you a full engine warrty even if you track the car. TTP makes there kit look like they car from factory.

That looks really clean to me. I know Tpp and Ruf do to some crazy R&D. Ruf Shop is amazing Nothing come up to Par, It very well orginzed and very well matian it, clean enought to eat of the floor.

Orton Supercharger is pretty ****in sweet and that thing has almost been out for a year and with no problems what so ever. And the same guy who did
Ruf ecu tuning did Ortons too. That other thing is that TPC is dosent have an ecu tune it a 7th injector setup, Not very polished to me.

Like I said I am not trying to start a fight!!!! And companies have the come around from there mistakes but when a 60k Car is on the line, I would rather have someone esle that has proven them self time and time again or Wait for all of the kinks to get worked out with other peoples cayman S. The kit hasn't been out for very long. And by looking at the past there first kit are the ones to blow motors. But hey if it reabile then it reabile.

 

Jury still out on reliable. boosting a high-compression motor with stock (cast pistons & rods, anybody know?) internals is a question mark. supposedly the factory tried to create turbo version of the "M" series motor for the 996 turbo but couldn't make it relialbe so they stuck with GT1-based motors. Admitedly it's only 5-6 psi but the fuel management looks a little crude with a just an extra injector.

 

The piggy-back ECU and an extra injector are tried and proven by them and other tuners, by not only adding fuel but in cooling the charge. BTW, there are two extra injectors, not one.

I got my car back from TPC in May and it still works! The combination of the turbo and my car is now at least 4x better than gtrmonkey's car.

 

gtrmonkey,

Sounds like you are talking about the old TPC supercharger for the 986, the one they pulled from production??

I heard about the horror stories with that kit, but again that was a totally different kit. I still wouldn't pay 20-30k to supercharge or turbocharge a Boxster, that's 1/3 to 1/2 of the car's value. The guys in the 996 forum are complaining paying 10k to supercharge their cars. I would opt for a option that put out 60-80 hp and didn't require a complete engine rebuild for massive gains.

 

IT the same mid engine setup? Why risk it, All I am is that they released a defected product before and happen with the 986 First ones, what to say It won't happen with this one. I don't want to be a gennie pig. That why I would wait a year or B go to someone esle, That has not had issues in the past. When you mod a porsche you know that Parts are going to be expensive. Its a given,

 

What your guessing a I drive a GTR since my screenname is GTRmonkey, Dude I had this name before there was even a conpect for an R35. Plus I don't drive a GTR, I drive a Bone Stock A4 1.8T Q 5spd. So the Cayman S is a 50X better car stock. You think your a badass because you got a TT on your cayman S. LOL That might blow your engine, ! Hey I would rather drive my Audi then to have a cayman that doesn't run. Your car is like a *****. It maybe satisfying now but it won't last forever. Just post a thread when you start having problems,!!!!

 

What other Porsche tuners are adding injectors in lieu of upgrading injectors? And what other Porsche tuners are using a piggy back ECU instead of re-programming the ECU?

For that matter, as a tuner, why in the world would you use a piggy back or extra injectors if there were other options available? I'm still scratching my head over that one....

None
And what other Porsche tuners are using a piggy back ECU instead of re-programming the ECU? none

For that matter, as a tuner, why in the world would you use a piggy back or extra injectors if there were other options available? Because it Cheaper than
investing the time to properly tune the ECU hence why TPC is 10k and Orton 20k.

 

This explains the benefits of the extra injectors:

"Since a turbocharger increases the specific horsepower output of an engine, the engine will also produce increased amounts of heat. This can sometimes be a problem when fitting a turbocharger to a motor that was not designed to cope with high heat loads.

It is another form of cooling that has the largest impact on fuel efficiency: charge cooling. Even with the benefits of intercooling, the total compression in the combustion chamber is greater than that in a naturally-aspirated engine. To avoid knock while still extracting maximum power from the engine, it is common practice to introduce extra fuel into the charge for the sole purpose of cooling. While this seems counterintuitive, this fuel is not burned. Instead, it absorbs and carries away heat when it changes phase from liquid mist to gas vapor."

Monkey...Thank you for your kind words and good wishes.

 

So what other Porsche tuner uses a piggy back ECU or extra injectors?

And while we all know the benefit of having the correct amount amount fuel in FI applications to avoid detonation, why not use larger injectors in lieu of the "bandaid" extra injectors?

Is there any advantage at all or is this just a way to cut corners to save the manufacturer money?

Likewise with the ECU... Rather than using a piggy back to fool the stock ECU, why not re-program the ECU for specific mapping? Is it because they can't and they have to result to yet another bandaid?

I know you guys are desperate for more HP and this is the only game in town for the Cayman, but I would be very cautious.... That being said, they are very nice people at TPC with a lot of racing experience. I think they need to catch up and start using the best technology available instead of patches.

 

"cooling the charge" by dumping fuel (running excessively rich) is a crude way to tune. are there any dyno charts with A/Fs? especially on a load-based dyno like a mustang? hey, im glad you are happy with TPC and hope you have no problems. I'm just think it's bit premature to call the thing bullet-proof. stock caymans have proven to have some issue when tracked so it would be interesting to see how a TPC equiped car holds up.

 

I'm lost with your statement because the kit TPC used for the 986 was a Eaton supercharger, their Cayman kit is a turbo. It's a totally different setup.

 

Deja Vu!!

I went through this struggle! I say just swap the engine and be done with it!

20k for a turbo kit, you have to be really stupid or extremely rich to pay for a kit like that. I guess the kit Gary has from turbowerx is unreliable too since it it only cost $7k. I guess his car is a ***** too, he's only had the kit for almost a year now, and I don't think he's reported any problems yet.

 

[20k for a turbo kit, you have to be really stupid or extremely rich to pay for a kit like that.

You have to have 20k, so your right on the rich part. But not stupid Part.

You completly miss read what I was saying, Has turbowerx ever put out a decfective kit. I don't believe so. Has TPC? yes they did. This has nothing to do with the cost of the kit. If the kit was propery done and it was 10k, That Fine.


I Don't think everyone needs to runing out scream TPC is the only opition because that is not TRUE. There plenty of other options out there there just expensive.
