to supercharge a 997?
Thankfully we can all express our opinions. I went with TPC becuase of the higher power and torque. The local tuners I talked with at the time, had told me that the VF kit was not as "impressive" as the TPC. The last thing I want after spending $15k on is something I'm not happy with. The TPC kit did give large gains in power and torque - very amazing. TPC has plenty of racing experience to back up their direction for the kit. It is a vastly different setup than the VF way. The TPC supercharger is much, much larger and produces more power/TQ at lower RPM levels. My 997 was a rocket with the TPC kit. And the screw SC used by TPC has been around a long time - it is proven technology. The VF SC looks like a small turbo (which it is bascially). I had the TPC kit on my car for over a year and loved it. My car was a daily driver and performed extremely well is an types of weather.
Again, I did the research when I bought my TPC kit. I suggest that anyone who is considering a SC for their 996 / 997 do the same. Then pick the kit you like best. I still would like to see some side by side tests (0-60 1/4m 60-100) for cars using each of the kits. That would offer more information to the drivers trying to decide which kit is best for them. If my kit were still on (de-moding - looking for a TT), I would offer up my car for such testing. Cheers.

The TPC kit is proof positive that a dyno chart does not translate into actual performance. If you were running a properly setup centrifuge SC, you would not need to sell your kit and move up to a TT to gain performace.
Funny how everyione always mentions the power of the TPC at low rpm but neglects to mention the lack of acceleration at the high end.

A few days ago, I had a long talk with Mike (Levine, maybe), the owner of TPC. I loved y VF and those guys are wonderful. I likewise was very very impressed with Mike's knowledge and convictions on his product. Also, TPC is a RACE team. Torque matters a ton on the track. A bit of noise doesn't (though I've never heard nor driven one).

Ditto
My car is making around 435 wheel hp and I would wager as much peak torque as the TPC car. As far as low end torque, I'm not driving a small block Chevy. It's a Porsche. Besides, when you're at the track, when are you ever under 4K rpm? I spend half my time trying to avoid the rev limiter

I've been in a TPC car. I was impressed with the power, but then again I'm really impressed with the power in my car too. It was the noise, power delivery, and install execution I wasn't impressed wtih. To each his own though...

I wish we were closer. I would love to put my car against a TPC car. I would wager the performance is very similar with the nod going to the VF car in a track condition where the TPC kit runs out of top end breath.
Everyone keeps talking about TPC "racing". We all know they race. That's actually one of the many reasons I didn't get the TPC kit. There was a period when I was calling to ask questions and it was hard to get a hold of them because they were racing....
Do they campaign a supercharged 996 or 997?
Can we see your dyno charts for your TPC car? I don't think I've ever seen an independent chart.
UM, I'm moving up to a TT becase it has more potential. That is the only reason. And to move up - I have to "de-mod" my car. But my 997s with the SC felt alot faster than a stock TT. After all the 997 is some 400 lbs lighter and the tpc kit is around 500hp at crank.
DD95: And I don't know what TPC kit you tested, but mine pulled ALL the way to redline very strongly!!!!!!!!!

Although some try to compare TPC with VF Engineering. It is the lack of knowledge that usually brings up TPC's product in conversation.

We may not produce race cars, however we do manufacture the best performance system on the market for your NA 996 and 997.
With so many positive reviews of our system on these very forums, there should be no comparison.
PM me with any questions, comment or for a quote.
Thanks!

- VF Engineering does not use an after thought type of fuel management piggyback system.
- We do not incorporate a secondary fuel injector as we are able to flow, test and produce injectors that work correctly.
- We also now incorporate the newest Vortech V3 supercharger. This new design give you a cleaner install and many miles of trouble free performance. Along with the new design, the V3 does not need oil feed or return lines.

I agree with this, other than the LWFW and LSD did this to me too... and the Motons. If you think you've got a badass sports car and you have anything less, you don't know. For real. Don't waste your money though if you aren't going to see how much speed you can take into a curve. Don't bother if you aren't going to go to at least -2.8 degrees of camber.
Back on topic. That's my short list of "make me stand up and take notice" mods.

Blakt Out,
I can't wait to see the February issue of Excellence that you'll be in. I had assumed that a 997TT is more desirable than a SC'd 997S. Now, there are some standard niceties in the TT: full leather, turbo wide-body, warranty, etc. that I won't get when I SC my 997S.
Here's a bedtime story about a little boy named the "CATTMAN". He used to drive BMW's, and loved them. He spent a lot of time and money modifying them, until one day he bought a Porsche, and told himself, 'CATTMAN, now you're at the top, there's no need to spend all that money on mods anymore, it's good to go as is!'. CATTMAN was wrong. Very wrong."
Point is: no matter what I buy, I'd mod it. I can guarantee you that if I had the resources and inclination to buy a Bugati Veyron, I'd mod it. And right there, that says is it all. I'll never be satisified, and enough is never enough.

I always heard that supercharges put a lot of stress on the engine internals because its an actual "gear" per say that is charging the engine. Is this not true?
I would venture to say that this may be semi true on a cogged belt system however with a standard serpentine type belt, there is a lot of flexibility between the charger and the crank.
-I think that is what is being asked here.

thats exactly what i was asking, thanks
