You would not get those numbers by "simple 650hp"..
What probably is more amazing is your torque/HP vs. RPM curve.

(It actually flew out?!! I had friends shooting bananas from their exhaust, but never a CC insert.)

Jean, just saw your post. Outstanding performance! Can you tell us a little about your engine? Twin plugs I assume. Do you have any pictures of the exhaust system you can post showing headers, catalytics and mufflers? Also, anything special about the turbos and intake? Twin injectors also?

Jean

Hi Bill,

Basically, a 3.8 Motronic Twinplug, with internals modified as well. The piece that stands out is the pressure sensing fuel system rather than MAF with shorter intakes to the turbos. I am running 1.1 Bar and will drop it to 0.8 base as soon as I install the EBC. No cats and a single minimum backpressure muffler. Running Garretts.

Here is a picture of the exhaust and turbo system.

Bill S.

Jean, thanks for the picture. I knew your exhaust had to be a completely different animal than Ruf, Andial or RS Tuning. That sure is extraordinary! Great job by Protomotive!

and I thought it was a stock exhaust...

Finally got the time and focus to take the CTR-2 out for a 60-130 on this beautiful Sunday morning. 78F here in Canada with a 1/2 tank of gas. The gas is 103/91 split 25/75, effective octane using R+M/2 of 94.

Runs were done on an AX/22 and I will scan and post data sheet in the next day or so.

Best 60-130 run was 5.86 sec. 60-140 was 7.51

My car is a narrow body version and has North American TT gearing not RUF gearing according to Alois Ruf. The advantage is better acceleration and thus performance closer to RS Tuning at the expense of top speed.

I am happy with my results.

5.86s is seriously quick - any chance of that speedo vid ? What sort of weight do you think you were running at ?
Just a point, I have noticed a few people labelling my car as "the RS Tuning" car making it sound like this is the best that they can offer and maybe some how comparable with Ruf's best offering. In fact RS through their extensive 993 GT2 EVO race program produce road 993tts like the one for sale in this link:
http://www.mobile.de/SIDLQrTWbYamcFe...1111165481090&
This car has the 20K US Secan intercooler and I have seen RS take these up to 700hp and 236mph. My car is as far as can be gone reliably (ie max on Autobahn or 10 min periods ) with the stock intercooler but as can be seen in the ad, in no way represents the highest state of tune which RS Tuning can produce with the 993tt.

Bill S.

Thanks for sharing! I didn't think the CTR-2 was that fast, but then again I never saw it tested with good gas and narrow body. Is your an original CTR-2 from Ruf or did you have Ruf convert a car for you? Also, does your car have twin plugs? What gears did you use for the run?

Also, if you can video the speedo, that would be good. Sometime those accelerometers are a bit off, depending on their internal setting and how they are mounted.

LAT

I don't have video setup but the AX22 works with a GPS sensor and I had it mounted on top of the roof with the magnetic mount. No possible interference from windows etc.

The major difference between my car and the one in R&T is the gearing. I don't have it front of me at the moment, but gearing is whatever a stock 993TT has for gears.

The car is RUF production model with a RUF serial number, originally imported by Frank Beddor Sr. from Minnesota.

It may be a while before I do this exercise again but when I do I will see if I can incorporate a video. What is the most common way of installing a video camera to do this?

Glad to participate.

LAT,

Can you post some pictures of your car? How long have you had it, and how did you find this car for sale?

BTW, that's blazingly fast. Would also like to know what gears you did that run in.

My quandry is 130 or 140 MPH is jail territory here in the U.S. I can't imagine where I can take my RUF BTR for such test runs.

Thanks.

I have had the car since last year, purshased it from the third owner in LA.

Regarding gears see previous answer.

It is not good to get caught doing 130 or 140 in Canada either that is why I do it early on Sunday morning on a remote road in the country.

The car weights in at 1,570 Kg (3,454. lbs) with fuel and no driver. I weight in at 180 lbs.

Konstantin

A 1540 kg car with 520 HP can not do these numbers.
even with 620 HP you will not make 5,86 sec
either the car has mich more HP or it is somethimng wrong with the set up in the AX 22.
Sorry but this is what I know from my experience.

Konstantin

LAT

Okay, not to argue, but what do I look for in the AX 22 set up to verify accuracy?

Dknebes

Ok, I received an E-Mail notification on the 60 to 130mph from the 993 turbo board and I still do not see a faster run than I made with my 89 930. Hear is the video again 60 to 130 and this was up for discussion the last time I posted, 5 or 5.1 seconds and 60 to 140mph 6 seconds.

check the runs with your stocl C4 cabrio and adjust teh parametrs till you get the right power and teh right times.
then you can see if thsi works with your CTR2.
the suspension is stiffer and need more adjusment but all in all we hope taht you are close.
Videos are also not relible enough since speedod and tachos also going fatsre than the reality
