David you are welcome, its a pleasure.

I thought I would post the 5 best runs I have seen so far. These cars are not the fastest from every tuner of course, but a good sample nevertheless. As far as 993TTs since this the relevant board, the fastest so far is TB993TT's. We will see more coming for sure.
I will try to find a way to post more than 5 in one chart.

Jean,

Thanks for the comparison. I suppose Jim will be checking his car. An Andial 3.8 with twin plugs and race gas should be faster.

Congrats to DKnebes. That's very impressive performance from a 930.

It's funny how you see three basic groupings, with the first grouping having very extensive engine mods:

1. Protomotive 996/Essa Tech 930
2. RS Tuning 993/EVOMS 750 996
3. Ruf Turbo R 993

As we expected, the 993s and 996s can be modded about the same. It would be fun to see a Protomotive 993. I heard about one that's very fast.

Jean, can you do a "virtual race" from the data? That is, if these 5 cars raced from 60 to 130 MPH, how far would they travel in feet? Given a car length is about 15 feet, we can race these cars against a Carrera GT and see how far ahead or far back they would be. I think many people would be very surprised at the results.

Does David's 930 have the good ole "4-speed" gearbox (915 I believe?) ?
This is probably a good thing (less shifts and a nice tall 1st gear!)

astounding, none the less--fantastic !!

Do we have numbers from a RUF 996TT 590 Nardo ??

Any info on the mods to the 930 and what sort of power levels it is putting out?

JamesE,

This should answer some of your questions: http://www.klsales.com/porsche/rebuild2.html

For more correct comparison there should be a 2WD 993tt category - this is a significant advantage as you know and I would love to see the results with Bill's and JJay's running 2WD - I reckon its worth at least a second ?

Hi Bill,

I have a Protomotive 993. Only Stage II, but it could be much more. Probably only pulling .8bar now. It is fast, but would have to do time trials to see. My 88 Turbo was quicker from 1st through 3rd, but this car may be faster at higher speeds.

I think there are several ways to classify the cars, they are all modded cars. One can argue that engines with internal mods should compare against each other, others that it should be aircooled vs watercooled, others by budget etc.. The objective for me is to see how HP claims compare more or less, other people might have different approaches.

TB, I don't think 2WD would take one second off in a 60-130 run, I would guesstimate more like 1/2 second maximum maybe but we don't know for sure, when comparing 993C4 vs C2 I seem to recall there were some small differences in performance, I have the test somewhere and can check it out. Loss of traction with 2WD is a major player as well, if fitted with a stock diff.

As we know, also aerodynamics play a large role too...etc..etc..This is why I say that these numbers are more of a general interest topic, in which each one can draw his own conclusions I guess.

Woodster, the Nardo ran an 8.3 second run but I don't know if it was its best attempt.

wow the dknebes 930 is a monster

These are the dyno numbers on my car.

Wow, 1.5 bar

Whose dyno was this run done on?

David, I don't tend to like (trust) dyno graphs more than for comparison purposes such as before and after a certain modification on the same car. We have seen such wild and unsubstantiated numbers from many tuners and dynos (not necessarily intentional of course) that it renders the data meaningless. This is the whole puprose of this thread in fact.

The performance numbers seen on your car are very impressive, and I think this IS the real story. Thanks for posting the logs and being so transparent.

I had some fun today with the data, and following Bill's request (after all he started the thread ) I did the attached graph which shows how would the cars have compared had they been street racing...i.e. who would be ahead and by how much.

The results are interesting, specifically when one looks at how the RS Tuning car of TB993TT, while being behind in a 60-130mph vs. the EVOMS 750, is however ahead in distance during the whole run... This means basically that if they were running against each other side by side, the RS Tuning car would have been ahead during all the run of about 1000 ft. Amazing huh for 200hp less!

To understand better the chart, as an example, after 6 seconds, this is the distance that each one would have convered:

VRALEX 881 feet
DKNEBES 866 Feet
TB993TT 838ft.
EVOMS 750 816 ft.
Bill S. 797 ft.

The difference between the first and last in the group is 84 feet, about 8 car lengths, after 6 seconds.

Just slipped into the country today under cover of darkness. I needed to check on the transmission damage that occured during my timed runs. Seems that the shift fork broke on one of my timed runs. Could be operator error or a weak link. Funny that porsche motorsports has steel high performance shift forks that were available for the GT2 racers; seems like I have to find the secret high strength parts the hard way. If your tranny is apart might be a good insurance policy to replace the cast aluminum piece with the machined steel one.

TB, one more part that is now a must have for your car. I'd include Jean, but he's morphed to the sequential box.
Best time as Jean said was 9's. I tried 4th, 5th and 6th high gear thinking the torque would get me low times, it doesn't. Also got tilt error on a down hill ramp runthat Jean wouldn't count. I'll have to do the video thing at the track now.
