It looks like LAT has 19" wheels on his CTR-2. I've been checking Rufus (also 19" wheels) against a stationary traffic radar (that was always dead-on with Waldo), and Rufus is about 5% faster than the indicated speed on the speedo. Of course, this is at normal traffic speeds, so no saying when you get into the 130-140 mph ranges.

You get an email notification if you have opted for it when posting on a thread - I guess you didn't know that ?
This is not an organ measuring exercise, it is 993tt owners enjoying what different tuners can get from our cars, you don't get a notification if someone posts a faster time
I think if Jean had a mind to, he could demonstrate a 5 second run, and without all the bouncy rev limiter and dubiously calibrated 930 speedometer

I know why I received this E-Mail. This was an entertaining thread when it started along time ago and I was invited at that time by a 993tt member to post on this board. I guess if it was a organ measuring exercise we would know who was the biggest dick.

TB,

Thank you very much for the link. My car is for sale now on autoscout24.de

Perhaps I can get the rs-tuning car with less miles for only an additional 15K Euros.

LAT

ca993twin,
the time and speed I used are from the XA 22 data sheets that I print out after the test. I am not looking at the speedo when I am doing this exercise, only the tach. Keep in mind that the XA 22 has a GPS unit built into it and thus it provides data regardless of wheel size etc.
Car & Driver found it to be extremely accurate.

LAT

Konstantin,
your suspicions were correct, I have tried the C4 and I am not getting realistic numbers.
I am going to call Race Technology in the morning for a hand in proper set up and rerun at the next oportune time.
It was fun while it lasted but I much prefer accuracy, thank you for the vigilant eye.

This car has been for sale for at least 6 months. There are not many people who want or could cope with the peformance What you have to remember is that you essentially have a GT2 EVO race engine which will not give stock like longevity and will need looking at every 10K miles. The clutch would also be a reason why I could not live with this sort of torque, it will have to be sintered which means like a switch - not nice on the road. But one can only guess at the performance - 1340kg and 650hp/850NM, 60-130mph in 5 to 6 seconds ?

Jean

LAT thanks for posting. IMO, the CTR2 must be the best looking 993 body styling ever produced. As Konstantin pointed out, it would be difficult to get those numbers with 1540 Kgs and 993TT gears. I hope you can redo the run as it would be really interesting to see how it compares to Bill S, JJayB or TB's performances (mine is not really 100% street).

David K., your times are impressive and will be very hard to beat of course, keep in mind that none of the guys are running close to your boost levels and 99% of them are on stock internals, Motronic controlled without EBC. The way I see it, is that this is rather a very informational and fun post that can help as reference to keep tuner claims (our own tuners included) in check. Thanks for posting.

Stummel, that RS Tuning GT2 EVO will be...a "handful" to say the least. Manthey will have an original one for sale soon, RS Tuning/Manthey prepped, 758BHP 1.4 Bar "street" car with less than 1300 Kgs.. You don't want to get there.

Stummel

Jean, it is not that I don't want to get there It is only a question if I can afford it yet.
What would be the output of your engine running 1.4 bar?

TB993tt,

My self and a friend that runs a 993tt that has more hp (850hp to the rear wheels) are running Tilton 3 plate carbon, carbon clutches that will hold 1450 lbs/ft of torque. The pedal pressure is close to stock and engagement is smooth not like a switch. Both cars are daily drivers.

David

Jean

Stummel, I don't know what numbers I can achieve, the key thing is for how many seconds and how much will the engine last. You can see a peak but will not sustain as the intercooler looses efficiency and turbos heat up, etc... The Secan will keep you there longer (other than very efficient, it is a huge intercooler).
David, can your 950+ FWHP friend do a 60-130 video for us? It would be interesting to see his time.

TB993tt

Thanks for the info, looking back you have mentioned this before, I forgot. I know very little about clutches, does anyone know if any of the reputable Euro tuners use these Tilton clutches - last time I looked into it it was sintered or nothing over 800NM.
Stummel - it may be worth asking Schmirler if one of these Tilton set ups would work - it sounds like it would make the car very streetable.

Woodster

LAT,
can't wait to get a ride in that thing, although it is possible I drove it when the original
owner owned it. My uneducated guess is that it will run 60-130 mph in about 7-8 second
range. You have an extremely fast and beautiful car, my friend!!

Here is the web page of the 993 with 875 rwhp. It ran in the high 9's. The video of the dyno pull is scary; the car even though strapped down very well starts to pull up on the rollers. My car is scary fast but his is crazy..

David the link does not seem to be working. High 9's is not that good for this hp, most likely because of a lot of wheelspin, that is why a 60-130 would be more illustrative. I wonder how can he still be using the 4WD system and not burning the VC and shaft.
