Supposed to be 530 at the wheels, yes new turbos, intercoolers and downpipes to the turbos, plus tuning.

 

check the 4wd.. It needs servicing after certain mileage as it stops working on 996s.. Its pretty typical issue of wear & tear.

 

Servicing? Last I checked it's a sealed system.

 

What are you at now?

Is that awhp or rwhp? Dynojet numbers?


Pending what types of numbers those are, a good set of tires like an NT-01 or V710 will give you all of the rear grip you need. Tires like an R6 will give up the grip long before they cord and you could be skating around in no time. R888's are ok, but the tread deep tread makes them less stable in the rear and on many applications slower than the NT-01 (similar compounds) Street tires will give you some grip issues, but mostly I've found street tires to provide less front grip and the rear is still ok, so you'll get far less grip on turn in so you need so much less in the rear.

In the rain, on a track alignment, even with AWD it will be hairy, even with AWD and an LSD it will be hairy.

Your alignment will also have bearing on the grip. In the dry, the car will roll more because of more grip, if your alignment is street'ish that will be decent in the wet. If you are going aggressive on the alignment and it rains, the car will be a REAL handlful, because now you don't have the grip to roll the car and flatten the tire patch to the ground, so you end up with only part of the tire on the ground and smaller patch. LSD will make that easier to catch if the car gets out of hand.

Of course that's if you drive in the rain, I will only once or twice a year and many just won't drive.

 

I don't drive in the rain period, except if I'm caught in a shower on the way home from the track. My car is still AWD. I have never been on a dyno so can't say. I'm only going by what my tuner told me as far as what the HP numbers will be. Right now I'm on K16's with a flash. It's supposed to be 490 crank HP. I'm using Nitto NT01's. Tried the Toyo's but hated the noise. I won't spend the money for Hoosiers and their short life. My alignment was set-up for the Rcompounds by my tech who used to work on the Farnbacher-Lole race team. As far as street tires go, I plan to flash back to stock for street driving. The car is so much easier to modulate on the stock tune and I don't street race.

 

Here is a video of one on rollers spinning all the wheels right at the 3:30 minute point. It's a RUF 550 Rturbo. I have the same car and know for a fact that the drivetrain (engine excluded) is the same as a 996tt.

Ok I see, sounds like you'll be making about what I'm making now. I stand by what I said. I have a LOT of video and data driving with my AWD TT and no LSD at the track, and I can count on my hands the number of times I've even had to make a correction let alone catch a tank slapper. As long as your throttle, steering and brake inputs are smooth and coordinated, you won't be fishtailing anytime soon.

If you don't get the LSD initially, let us know how the car feels after a few events. I'd like to know your impressions.

 

Just as an FYI, we were the OEM LSD supplier for RUF during the 996 years. If the vehicle was spec'd with an LSD from RUF, it will have one of our GT2 Pro chromoly units installed in it, usually set at a quite aggressive 50/80 locking factor.

 

Is the RUF with your LSD AWD?

 

After your mods you could always add a EBC boost controller, Chris added one since I am tracking my car more, way to much HP for the track coming out of the turns...something to think about, you will have 3 settings, off, low, hi so you can experiment and be able to adjust for different tracks as well.

 

OMG...

It's been a long time since I posted here but couldn't resist when I read this Topic... Matt I feel your pain

 

I may be wrong but I believe that RUF only put the LSD on their 2wd cars and not the awd Rturbo....

 

The stock lsd with the porsche motorsports clutchpacks works very well.

 

Does anybody know if the turbo s cars come with the LSD standard?

 

I was very particular in my statement above because of how Ruf specs their vehicles. We have never known exactly which vehicles Ruf installed our LSDs into. We just know that we used to sell them a couple dozen units a year for use in both production vehicles and customer conversions. I would assume that just like every other vehicle produced at Ruf the final spec lies with whomever is paying for it to be built. I always chuckle when people talk about "standard spec" on a Ruf because they are bespoke vehicles. No two vehicles on the production line, even by the same model name, will be identical because they are built to order. They have their own in house show and test vehicles that are in the magazines and on display at Geneva and London and Tokyo, etc. but even those cars are just an example of what is available.

You would know better than I if your car has an LSD in it or not. But if it does, it's likely one of ours.
