I have a thread somewhere on here in the 996 section, where most of the owner's on 6speed posted how many miles were on their kits, dyno results, mileage since the install of the kit etc. I think it's under supercharger owner's thread or something like that. It's a good read for anyone considering one.

 

nice, exactly what i was looking for

 

996TT's are no issue what so ever. I, routinely, walk the same two 997TT in an area I travel daily. Always see the same two and play. It starts out the same way as you. Then I have a bud in a 997TT and he walks me 4 out of 5 times. I think it all gets down to the driver. I have a bit more the the SC and have added the TPC UniQ which adds 30hp more. I am also looking to throw on the plenum mod. My buddies 997 is absolutely amazing and very different than his previous 996TT.

 

if you find the thread, post the link. I'm constantly losing it.

 

here it is here...

I can only assume the other two 997TT's either aren't trying or aren't very skilled at driving. Of course how hard is it to hold down the right pedal and keep the car straight? Since the third 997TT can beat you I would be willing to wager all three could beat you if the other two got their act together.

The TPC and EVO kits are very similar in performance. There was a thread here a while back where they actually ran a couple against each other and it was very close.

My car is making about 435 to the wheels with the blower, headers, exhaust, and plenum. I've done dynos before and after all the mods.

I don't believe my car, or any other SC kit out there (can't count 99's, his kit is far from stock), is walking (by definition easily pulling away during a straight line race) a 997TT. Just look at the 997TT torque curves. Forget about it when they're in over-boost. I'm happy just hanging next to them at this point with my porky pig 02 cab I'm sure the GT2 and the next gen turbos will take it even further.

 

that's the one. good work detective

 

Although I would like to see a TPC dyno chart with the Uni chip mod. Do you have any you can post?

 

Sounds like a good time....Becarefull of the TT you try not all are stock

 

DD,

Def agree with the driver ability thing. Lot of the Porsche guys around here drive for status and are a bit on the stuffy side. I do not have a dyno with the current setup. I dyno'd 398 and 412. 412 was with a bit of race gas. Did the 398 w/headers, high flow cats and b&b tri-flows. I hope to be in a 420-440 w/plenum and uniQ addition next time. I know that may be a bit on the high side but we can only hope. I think one thing that helps me tooling around with cars here is the JRZ suspension. Although very smooth and comfortable around town, it is very rigid in the sense that I feel as though I am surely loosing the least amount of energy between "us" when getting into the throttle. I should be on a dyno somewhere around the second week of April and will surely post. I have read alot about different readings on different dyno's. Any of you guys have a preference for which dyno to get a reading from?

 

Does anyone have a TPC Supercharged dyno? One by RPMs? The one on their site is by speed. I'm right outside of DC so I need to go check these guys out. TPC uses a Eaton, positive displacement supercharger, which is probably more responsive and will give more low rpm power than the EVOMS. I do like the simplicity of a centrifugal supercharger as well though. I thought the new Vortech's had self contained oil? I'm a fan of that, as having oil lines is just one more thing to worry about. These kits are the same price and seem to be about the same in performance, from my experience for street use, a positive displacement supercharger is more fun.

 

I will have a dyno for the TPC the second week of April. The TPC is amazing. I have a vast amount of experience with the Vortech adn force fed a Vortech kit with race injectors, aftercooling and 11.5 pounds of boost making 520hp but it was on a BMW. Not a real difference between the kits but that experience was only the BMW. 1999Prosche911 has a crapload of experience with the Vortech on a Prosche and from what I understand, his kit is pretty well modded and/or tweaked in a few ways. I do like the roots style over the centrifugal myself because the power is on tap at the tap of the pedal. There is no lag with either compared to a turbo but the Vortech builds boost where you are right, the roots style has full boost right out of the gate. Last year, with a stock TPC kit, I dyno'd 383hp with no mods and pump gas. This year I will hit the dyno with high flow cats, headers, plenum and TPC uniQ software. I hope it takes me somewhere in the 425-430 area.

 

^ Cool, I will look forward to that, I don't have the money to drop on one right now but the TPC kit looks amazing. I think I will go that route when I can afford one. Plus they are within 45 mins or so from me. 400 WHP is sick, plenty enough for me! I like the low boost approach since the 911 has relatively high compression. Looks like both kits are very reliable. I like how the TPC kit has self contained oil in the unit. I'm really looking for a little more go with reliability and I think it's better to go with a kit like this then spend almost the same on bolt ons that will only give you a fraction of the power. So before the uniQ, do they just reflash the ECU? Or is the stock ECU able to adjust with the MAF? I've always gone with after market fuel management but know that with a supercharger it's a lot easier.

 

Before the UniQ, there is a piggy back control module that is PnP to the OEM ECU. The UniQ is piggy back module as well. There is a more advanced and aggressive fuel mapping and an additional fuel injector that is installed.

 

You DO NOT want self contained oil. One of the advantages of using the engine's oil system is the cooling. Also, one of many drawbacks of a positive displacement blower (it is not a compressor like the centrifuge), is that the power hits a wall at higher rpms. The blower may give you power a little sooner and looks good on a dyno chart, but winning races is all about acceleration and a centrifuge SC wins that battle everyday as it builds in power all the way to redline.
