60-130 MPH: New performance measurement!
#871
I think it is in line with 540hp.
Stock turbos, only ECU and exhaust+cat.
Could it be that 100-200 suffers from tiptronic gearing i.e. there is a shift right after 100kph?
Nevertheless 3.24s from 0-100 sounds like fun and good traction.

I have done a few (rather many) runs with a stock 993TT of a friend late last night, the car is bone stock with only emptied mufflers or cats, not sure..
It felt great driving a stock 993TT again, it had been a while. The car runs very smoothly and I just noticed a very slight hesitation at around 110mph, might be some spark plugs, hardly noticeable. I did a few runs to get acquainted with the clutch travel and gearing, and I think I mastered quite well, judging from the improvement in shifting time.. I am surprised at how quick one can shift with stock cars without being rough.
I first did a run where I forgot the A/C unit on, also I hit the rev limiter in 4th gear for about 0.2 seconds by mistake....My best time with 2 shifts, AC on, 3-4-5th was 12.99s.
I then did a run with 1 shift, no AC, 4-5th gear, changing gears just before redline...Best time of 12.5 s. The car is a pig under acceleration in 4th. between 3,400RPMs and 4,500RPMs where acceleration picks up nicely.
I would say the AC makes a difference of about 0.3 seconds in such a run and one can see the difference in acceleration between the red line and black lines through third gear (60-90mph approx)..Red line being no AC.
Finally, the fastest run, with a quite impressive time of 12.2 seconds and 2 shifts 3-4-5th gears.. Major contributor to those times was the good shifting.. Weight is stock, including the spare tire etc.. I weigh 180lbs (ok a bit more ), temperature was around 90F. The numbers are very close to the Autocar test https://rennlist.com/forums/showthre...hlight=autocar that TB993TT posted. They quote a 60-130mph of 12.3 seconds.
I am attaching my three runs next to each other..You can read all the details of the runs in the little box inside the chart.
And here is the fastest run in greater detail.. Notice how quick the shifts were

Kevin, you could be right, I just remembered that it should be the case, however the AC does not stop cooling if I remember correctly, I would certainly notice after a couple of runs... It is the same road......

that is cool Jean, I also loved my 993TT (before and after mods)!
Another interesting comarison:
$225,000 Ford Mustang FR500GT (Race car)
3300 lbs (curb weight)
534 hp @ 7100 rpm
440 tq @ 5300
6 speed sequential shifter
1/4 mile == 12.1 @ 123 mph
0-60 == 3.9
60-130 == 9.8 seconds (about 1 second faster than my PSI 480 horsepower)
Does this sound about right given the published specs on the car?

That is great benchmarking information thanks for taking the time to document it.
Your ultra fast gearchanges inspired me to go and try a couple of lever ripping runs - I have emailed you the results, perhaps you could post the fastest when you have verified and got a spare minute

Here is the run of TB993TT... 60-130mph in 6.9 seconds!! This is clearly the fastest MAF based air cooled car I have seen so far, and no crazy boost levels.
I have compared it side by side vs. his previous fastest run (TB pls correct me if wrong) Pre-Secan and other mods (It was 60-130mph in 7.6s)..
It is very obvious that the new setup has much higher torque across the board, notice in the little box his average long Gs of 0.48 vs.0.41 previously, that's a 17% increase across the duration of the run.
More importantly, the distance covered to go from 60-130mph has been reduced by about 100 feet. From 1125 Feet to 1025 feet.
When you are looking at these graphs and comparing long Gs, remember that the 993s are doing these runs in 3-4-5th gears, while the 996s (and 930) are doing them in 2-3-4th gears due to their taller gearing, therefore putting much more torque to the ground.
I will let TB tell you more if required.. I think there is temperature difference between the 2 runs as well.
Here you go!

What is particularly interesting to me is that going from 7.6s to 6.9s sounds like nothing (particularly for the "investment" made) but as Jean points out, it does it in 100ft less - this factor is really noticable. On the "track" I use, I mentally knew how far down I expected to be at 130mph but hit it visibly much sooner resulting in actually having much longer to brake - so more power actually makes the car safer

I'm confused... do you start this "benchmark" CRUSING at 60mph, then drop the hammer until you get to 130mph?
or do you take off around 30mph, and 'start' timing at 60mph and 'stop' at the 130mph point?
Thanks for the clarification...

Now all TB has to do is some 1/4's so his times will have credibility!!! ( tongue is in cheek and I am ducking !) This actual data is getting more interesting as it goes along.Even many over on 6spd are now taking an interest.We might even get the "worlds fastest" to put it to the test!!
Great times TB and very, very interesting.
