Your car will walk a Ruf 550! There is one in the Woodlands...if you are interested in a little wager?

It will actually take less.
A 996TT with a drag coefficient of .31 and a frontal area of 23.5 requires 408 whp to reach 200 mph (a stock car will hit 189 with only 345 whp). An AWD car needs 500 crank HP to put down 408 to the wheels (18.5% drivetrain loss)...while a RWD car needs only 467 crank HP to make the same whp.

Agreed. A RUF 550 wouldn't stand a chance. It's not even in the same league a 700 HP TT or GT2. It would take a RT-12 to keep up with Paulie's car.

No RUF will do over 189 (or so) MPH unless it raises your RPM limit. A lot of tuners have that option. The Stock X50/S is RPM limited at 189 MPH.
I think you will be better served with the 660 KIT or a nice 24/18G kit at a fraction of the cost.
BTW beware that the the 10K number people throw around assumes you already have an airbox, diverter valves and exhaust. Realistically that's another 4K.

I agree with you. But for the original poster, I'm quite sure that a Ruf 550 car is faster than some "stage 4 600hp" that comes with like only K24's, chip and exhaust...I have personal experience about these things.
Many European kits might be too pricey but their power is like their stats show. Due to different dyno measures people should more look at the parts being changed. I won't mention these big companies but here's some thoughts.
An example: Would you go for 542hp kit from Germany, another German 600hp kit or a 615hp kit from the US?
Sounds easy to answer?
Well I make a few points:
European tuner 1: K24 + Chip + Exhaust + Filter = 542hp
European tuner 2: K24/26 + Chip + Exhaust + Intake + Headers + Plugs + IC's + FPR + Clutch = 600hp
US Tuner: K24 + Chip + Exhaust + Intake + Headers + Plugs = 615hp
My educated guess is that these "542hp" and "615hp" cars are similarly fast while the second "600hp" car is bit faster than both.
So don't let the numbers alone fool you...

That said, "pump fuel" in Europe includes 98/100 and even 105 octane, which is 93, 95 and 100 octane here in the US. So, the "pump fuel" in Europe is sometimes equal to some of the unleaded "race fuel" here in the US.

Another thing is that RUF includes LOTS of other parts that is not included in the list. Of course they are still sick expensive, but their warranty and reputation goes well with the gentlemen who wants reliable power...

Ari,
My SG kit that ran 11.5 can be done for right around 10K, the 16/16G set-up Seal mentions can be done with exhaust for more like 6K installed. All he needs is to upgrade his turbos, ECU tune and exhaust. Even if you throw in DV's, not much difference...
As for RUF's power, the track tests don't lie and the acceleration figures put down by the RUF cars are nothing out of the ordinary for their level of tune.

US fuel octane is 4-5 points lower than Euro fuel, since we measure a combination and RON and MON...while Europe only measures RON.

Kaizu,
I agree that it is difficult to make 600+ with K24's.
These dyno games get fun...I have a realistic 650-675 HP at crank even
though I pulled 628 on a dynapack (reads high), and some people call my car a PE700
(It is not 700 Hp of any kind, but it does go "pretty well")

This contains:
Performance Kit 4,
630 HP / 464 KW , 790 Nm
consist of:
-2 New Turbochargers F650
-2 9ff Camshafts
-2 9ff Exhaust manifolds
-9ff Valve-Sport Exhaust 70mm with end pipes
-100cell Sport Metal Catalytic Converters
-Stronger Clutch Kit ( 950 Nm )
-Air Filter + Air Hose + Air box
-9ff ECU upgrade
They also quote: 0-100km/h in 3.29s, 0-200 in 10.38s and 0-300 in 24.8s
These are for the 996TT/GT2 (not sure whether these figures refer to TT or GT2 though). Even so if the nos are true then their 630HP package is faster 0-300km/h than yours Woodster!

Go with ruf if you want piece of mind,
but there are loads of other great solutions too.

I miss spoke ! I just came from the Texas Mile Race last weekend and should have said in 1 mile, as that was what I was thinking about. You can get 200mph out of a lot less Hp. with an unlimited distance to do it in. My error in wording.
