giac tuned being done up at giac not just a flash download

I think there stage 3 kit put over 650 to the wheels but cost almost as much as the car

 

I have the non flash GIAC on my TT- it didnt jump that much in HP but the gains are amazing.

 

techart or something like that has a kit to get it to 600

chip,exhuast,clutch,intercoolers and turbos

theres a stage 4 the owner of giac that is putting well over 700 at the wheels with his 911 so it depends how much this guy has got into his 911

the regular flash from giac gets you about 90hp and about 70ftlbs and the dealer can install the flash if you want

now you can get the x50 that gets the car to 475hp i think now and then flash that kit to about 500 plus but the x50 packege cost like 30k from the dealer so your better off just getting a reg 911 and having a tuner upgrade it to some k24 turbos and save a **** load of money

 

Even so, you need to do A LOT to the car to reach 550 at the wheels, at least on a non-X50. Even then you'd need to upgrade the turbos to get to 550rwhp on a 996TT or GT2 for that matter. Very few 996TT's are making this kind of power.

 

I know thats what I ment you never know what this guy could have.I just read over at 6speeds that bone stock gt2s are putting 450plus to the wheels on a mustang dyno

the same guy then used a giac flash and exhuast and got 510whp and 470ft lbs
the x50 is the gt2 turbos on a reg 911 so this guy could have close to 500 at the wheels if he has a x50 and a flash on his car

 

Recall that the 996TT is AWD and would put less power down due to the drivetrain losses. Still, you have a point, the 996TT X50 with mods is no joke.
Whether the guy was a jerk or not the 996TT is one hell of a car.

And Vic55, enough talk about your P-car. Let's see some pics!!!!

 

Ahhh, he's running stock I think. Just listening to you guys talk about P cars, you know you guys know your *****....this guys literally said "it'll run.....(pause) uhhh in the 11's" My only concern if I ever meet up with the guy around here is that turbos do perform better at 4300ft than my poor blower.

I hate to say it, but unless I was down lower alt like most of you....he would probably pull me....at least it would be close. Regardless.....I would sure give it the ole college try.....I'll try make us proud.

Sure wish there was a way to have boost turned up because I am a friggin mile in the air.....Kleemann said it's just too risky. Plus one trip to CA near sea level and I would risk toasting it.

Can't wait...taking it to Sacramento when it gets super cool....should turn some killer times at sea level. Guys at local track literally said most cars run a full sec better there....then here.

 

I wouldnt sweat it. The air density is the same regardless of psi, he has no more advantage being turbo than you do being s/c'ed.

 

600 hp / 441 kW, 740 Nm, 0-200 km/h in 11.9 sec., Vmax 334 km/h: TechArt Automobildesign (www.techart.de ) turns the Porsche 911 Turbo Cabriolet into one of the world’s fastest convertible cars.



The TechArt TA 096/T3 tuning kit boosts power output of the water-cooled 3.6-liter flat six engine from standard 420 hp / 309 kW to 600 hp / 441 kW. The conversion comprises two larger turbochargers and intercoolers, special aluminum intake manifolds, a sport air filter and the TechArt stainless-steel exhaust system with integrated high-performance catalysts. Newly programmed engine electronics ensure that all modifications work together flawlessly.



The conversion not only benefits maximum power output: Peak torque grows from standard 560 Nm to 740 Nm at 4,600 rpm. Power is transferred to all four wheels via a custom high-performance clutch and a modified six-speed manual gearbox with TechArt shift travel reduction.



Thus equipped the TechArt-tuned Porsche 911 Cabriolet is firmly among the world’s fastest convertibles: The sprint from 0-100 km/h takes just 3.7 seconds. After just 11.9 seconds the car reaches 200 km/h. On the high-speed track in Nardo, Italy the Porsche reached a top speed of 334 km/h.



This kind of performance places the highest demands on aerodynamics. Using a wind tunnel the TechArt designers developed aerodynamic-enhancement components which not only produce optimal aerodynamic downforce but which also lend the Turbo Cabriolet an unmistakable appearance.



The TechArt GT street front apron with adjustable splitter produces downforce on the front axle and provides the various radiators, intercoolers and front brakes with an extra dose of cooling air, thanks to its larger and strikingly styled air inlets. In addition, the integrated center air outlet improves venting of the radiators.



The TechArt side sills calm the airstream and better route the air past the rear wheels. The TechArt air routers in the sides optimize the supply of cooling air for engine and intercoolers.



The TechArt GT street rear wing comes with adjustable angle of attack which allows the 996 Turbo Cabriolet to be trimmed either for maximum downforce or for a higher top speed.



The TechArt GT street rear apron with integrated diffuser also contributes to the high downforce on the rear axle, and provides the perfect backdrop for the two characteristic dual tailpipes of the TechArt high-performance brake system.



The TechArt Vario suspension, developed jointly with Bilstein Racing Service on various racetracks such as the north circuit of the Nürburgring and the Hockenheimring, offers a sporty yet comfortable ride. Contrary to conventional coil-over suspensions the TechArt Automobildesign’s innovative solution not only offers the possibility to lower the ride height individually by up to 30 millimeters on front and rear axle; the TechArt Vario sport suspension also comes with sport shock absorbers with adjustable bound and rebound. Together this allows the suspension to be set up to the individual preferences of each driver and to the specific use of the car – on the road or on the racetrack.



The TechArt/Bilstein struts are further equipped with modified pivot points for the sway bars and with special suspension mounts.



Another large part of the sporty handling of the TechArt-tuned 911 Turbo Cabriolet can be credited to the especially light one-piece TechArt Formula five-spoke wheels. The TechArt GT street S 911 Turbo Cabriolet comes with these light-alloy wheels in size 8.5Jx19 in front and in size 11Jx19 on the rear axle.



TechArt technology partner Continental supplies the perfect high-performance tires for the TechArt GT street S in the ContiSportContact 2 Vmax. They are mounted in size 235/35 ZR 19 on the front axle and in size 315/25 ZR 19 in the rear.



The TechArt interior program for the 911 Turbo comprises exclusive fully leather interiors and numerous sporty accessories. The product lineup ranges from various versions of an ergonomically shaped sport steering wheel with airbag to aluminum foot rest, pedals and shifter to stainless-steel sill plates with TechArt logo.

 

Ruf Rt12 = 650hp!

 

This is not really true. read my previous post. It explains why.

 

supercharged M3 vs. TT996 X50


http://www.acurazine.com/forums/showthread.php?t=319496

I would assume the E55 STOCK can do just about the same as this M3. With a K1 or EvoStage 1, it would be a slightly different story.

M3 is lighter, but it lacks the low en torque.

From what I read... Active Automotive Kompressor puts about 500hp to the fly (NOT to the wheels) torque is 390+.


From a roll E55 with a simple pulley and ECU upgrade will be able to pull away.

 

if your talking about 1/4 mile drag racing and 1/4 mile times and this numb nut answers back with a 0-60 remark then hes probably full of it and has never been on a drag strip in his life!!!

 

It really doesn't explain much.

 

Supercharger is driven at a fixed speed in relation to engine RPM. With altitude, amount of boost available is less due to thinner air. It is still pumping the same volume.

Turbo is driven at a variable rate. Thinner air means turbo spools faster as RPM and heat rise. Pressure is still limited by wastegate but performance will not suffer as much as supercharger and why turbos are better on planes.

BTW, planes are not usually boosted over sea level pressure.

 

I really dont think that x50 was trying.The aa m3 stage 2 puts down 390whp 280 rwt

theres now way it could keep up with an x50 400+whp 350+ rwt
I love m3s to death but im not feeling that video at all

and on the 120 run it looks like the x50 stoped trying.That car should fly to 180 like nothing on the highway

 

I thought turbo is spooled by the exhaust gas that goes through the turbine that drives the compressor. So I believe the turbine's speed is driven by how fast the exhaust gas travels through.

As the outside air gets thinner, the bigger the pressure and the temperature difference between the air inside the engine and outside the engine causing the exhaust gas has higher speed, thus, making the turbo spool faster. Yet, since the outside / intake air is thinner, the discharged compressed air still has lower pressure, thus, lower engine power.

As for the wastegate, I think blocktrader is right. Wastegate would open at the same pressure regardless car's altitude. Since the turbo gives lower boost at high altitude due to thin air, the wastegate should open less frequently than lower altitude.

As for the airplane, similar concept happens... but it's more extreme. The exhaust gas travels faster because of higher pressure and temp difference between inside and outside the engine, and the intake air goes to the compressor faster causing natural pressurized air prior traveling through the compressor, which greatly offset the thin air density. Plus the compressor is so huge (a lot bigger than car's compressor) that it increases the intake air pressure a lot higher than the car's engine.

As for S/C, I think the same concept also applies.... except, the turbine in turbo that drives the compressor is replaced by pulley and belts that is driven by the combustion engine's RPM.

I may be wrong.... or may be we are saying the same thing Can do research but too lazy

 

You are right, we are saying the same thing. I had comsumed too much vino last night to make sense!

 

You'd be surprised at how many turbocharged airplanes have ZERO boost at altitude. They are called turbo-normalized because the turbo boost only brings the engine back to sea level.

 

Are you a pilot or something?

Hey, you're in Bay Area, right? Are you up to the 969 GTG some time in October? I heard only redlineroberts and MrAMG from this forum came. And MrAMG was the only AMG as redlineroberts brought his lambo murc

 

No but I did sleep in a Holiday Inn last night! :p

We had a few different planes over the years. Last one was a Turbo Commander which contrary to its name, is a turbine driven propeller engine and one sweet performing 7 passenger airplane! I still know many people with private aircraft.

Weekends in the fall are tough. I'm usually laboring in the vineyards or winery until mid November.

 

Okay, I will be real specific. Pounds per Square Inch or PSI is a measurement that quantifies air density (at least as it is referred to here.) So the statement "air denstity is the same regardless of psi" is not correct. The more PSI, the denser the air. I assumed that part was obvious, and this statement I made: "The wastegate will open at the same psi at 5000 ft as it would at sea level. The difference will be that the compressor will spin faster to make that pressure." explained enough.

I should add that I haven't stayed at any Holiday Inn's in a long time, so I probably don't know a damned thing.

 

LOL! I shouldn't drink so much wine before posting! I couldn't understand what you were saying yesterday when I read it.

 

That's not a correct statement It should be the other way around... the denser the air, the higher PSI it has j/k

Enough of this S/C vs. Turbo thing.... just wait and see how Jakpro1 kicks TT owner a$$

Jak, any date yet? Make sure to keep us updated

I'm a huge fan of Porsche but this TT owner is a disgrace to a Porsche.... just like my wife says someone who cannot play piano but buys a $120K Steinway
