Long story short.....I was offered a deal from a well known company...they were going to build a twin turbo set-up for my car through an affiliated shop.Problem was they were VERY slow to respond to emails to sort out the details(due to the fact that they ARE extremely busy)....so I thought IF it takes this long to get through details,how long was it going to take to build the system.......
I was worried I that they would have my car for too long(6-8 months).

So that is when I contacted TPC racing for their kit!
I wanted MORE power at a lower RPM than what the supercharger could offer!
AND the fact THAT TPC's kit comes with FULL exhaust.....IT IS MONEY SAVED!
If you already have exhaust,you can sell the parts to offset the cost of buying their kit!

For more boost with the supercharger I would have to pull the charger and change the pulley,belt and few other bits....quite time consuming!
With the turbo set-up and optional boost controller.....NOW all I will have to do IS twist a dial for more boost!
TPC also offers a switcher for different octanes of fuel and because I am going to run a water/meth system down the road...it only made sense to try this turbo set-up!


With the supercharger,you wouldn't even know it was there...OR not until you nailed the throttle!
It idled fine,ran amazing....NOT one engine check light!

I am expecting the EXACT same with the TPC turbo set-up.....
Marathon Bob (forum member) has had this set-up for a while now and he LOVES it......oh wait....he loves everything EXCEPT for the speeding ticket he may eventually be getting,LOL!

I can promise you one thing....with 5 PSI of boost...the car is a BLAST to drive and speeds achieved happen in a fraction of the time it did when stock!

Not having firsthand experience with either FI system, I'm pretty much warming-up to the TPC turbo sys that Stacy is waiting on. Seems to be a quite a well-thought out, sorted-out package, the bonus of the exhaust system (that according to the vids, doesn't seem to mute the exhuast note like some turbos do) is a great perk, and I like the spirit of the company who produces it. I just have one caveat that applies only to myself- my heart is set on that wonderous Werks1 airbox for the 997.2, and I'm concerned it might conflict with the TPC turbo kit hardware.

I know I know, it might be "shallow" of me, but that CF airbox is da bomb when you lift the lid... Absolute BEAUTY!

 

Jim,

if you do have means and real possibility to get '10 or '11 turbo S - get it. 996 NA will never run as 997.2 PDK turbo does.

as of what to do with your 996 NA - TPC system give good power, used VF-E supercharger system could give nice power increase too. But if you can get real turbo p-car - go get it and waste no time on FI for an old 996 NA car.

 

Once the mods start, they never seem to be done

 

High Flow Cats and Headers + ECU Tune is probably the most power you'll make before Forced Induction.

 

If you want performance without FI, the LWFW doesn't give you more HP, it just gets you to the higher HP faster.

 

I've had my TPC turbo'd car for nearly 6 months and have totally enjoyed it.

I was interested in a supercharger about 2 years ago but became turned off when I noticed lots of complaints online about the nearest installer. Too bad Stacy didn't live close by!

I followed the threads on TPC's turbo and became intrigued all over again. I've driven a couple of modern Porsche's but never a turbo so I can't compare my car to a Porsche turbo. I can say that it completely overwhelms any C2/S, C4/S that I've driven.

It has a deep throaty, but not objectionable, sound when driving around town. I hadn't even considered that prior to purchase, but getting a tuned exhaust system with the basic system was a nice surprise. Under ~ 2700 RPM it performs like stock. More than that, or when you mash the pedal, it's a monster (sounds like it too) and it's a thrill ride every time I'm in it.

There's an undercurrent of fear on the boards about whether the car will just plain explode due to the added boost. I'm no automotive engineer so I couldn't easily evaluate the risk, but I didn't notice much in the way of online postings about either aftermarket supercharger or turbo's blowing up the engine. I have heard anecdotal references to people who pushed so much boost that the engine did suffer damage. In the case of TPC, the boost levels are quite low in the range of 4.5 to 6 pounds. So, I decided to take the chance and have had no issues to date.

I don't think any of the mentioned aftermarket tweaks make much sense if you're going to be trading in your car anytime soon to a dealer. You won't get your investment back, although if you've retained the stock pieces you can revert to stock and sell the updated parts.

As for all the other horsepower adding tweaks you can do to your Porsche, it seems to me that none of them come anywhere close to matching the horsepower per dollar gains that a turbo or supercharger can add. Add TPC's racing heritage and knowing Mike Levitas will be personally involved in tuning your car (presuming TPC installs it), was icing on the cake and sealed the deal.

If you want to hold onto your car as many of us do, then I think it's *relatively* short money to completely and positively transform your car.

Good luck with your search.

Hi Bob, Thanks for the input. That is the problem for me, is that I am on the West Coast. I would have to have it done by my local repair guy, who may be clueless if something adverse happens. I am waiting to see what happens to the other guy on this board who is 6 wks into the installation process.
Jim

 

Hi Casey. You guys sound really good and reputable. That is what my car is-05 3.8S. My ECU is probably the same as his. Do you have any installers close to San Luis Obispo- Central Coast CA?
Jim

 

Jim,

If you have an '05 I'd suggest to you and others with an 05 to sit tight before pulling the trigger on this kit. We have run into something of a snag in loading up the software into the "orphan", "unique", "bit different", or however you'd like to characterize it, ECU that is at the heart of the 05 997...

The good news is I do believe I have one of the very best minds as it relates to Porsche working the issue. I'm confident TPC and Mike Levitas will resolve this and come up with a workable solution -- the only point being I don't think any of us know for certain what the eventual solution will be... he's got a couple more ideas to try.

Also, fortunately, TPC is absolutely committed to doing it "right way" which means it will be safe and reliable with factory-like driving characteristics. At least that's what I've been promised

BUT - we are where we are with no solution yet - so stayed tuned if you own an '05. Otherwise 996 and 06 997 and later owners - have at it!

Eric

 

Isn't Stacy's car an 05 as well?

 

Thanks for the info.

I have an 05 but it received a new engine in 09 when the IMS went. Would it then fit into the OK to move on department?

 

Hmmm - I'm not an expert on this (or even have much of a working knowledge), but it's unlikely that they changed the ECU when they swapped engines. The ECU talks to a lot of different subsystems than just the motor and the ECU even requires a different wiring harness between the 05 and 09. The 09 and 05 motors are identical and the 09 should have been a drop in replacement for an 05 without any modification to the ECU at all.

OK experts - did I get that right?

 

sounds right...thanks

 

YUP........

Stacy
