I know many in here prefer this test, especially those in Europe.

I like it as it is a pure measure of the cars acceleration, with the driver being involved, tires, launce, etc. Basically eliminates a bunch of variables.

This is a cool list. Please feel free to post your personal times. This really does show the 951 up ther in super car status

Sorry, with the driver NOT being a factor.

 

6 sec, @ 16psi before I cleaned up the AFR. Waiting for nicer weather to
check again @ 18psi
This was 3rd gear BTW, I wonder what gear those cars were tested at

 

so, why are we not on the list?

 

The 951 is VERY good for this test. The gearing and powerband are perfect.
If I start at about 50 and go to 100 in third (22 psi), I am at 4 seconds - that's conservative.

 

That's an awsome list, Todd.
I guess it's too bad that a stock 951S is not part of the comparo.

And yes, I think this is a much better way of measuring performance; 0 to 60 times mean nothing to me.

 

Are these a "hold at 60, punch it and accelarate to 100" test? Or is it "accelerate through 60 to 100" test? Is there any specific gear that is chosen or does it vary by car?

I read once that the Porsche 944 Turbo S had the quickest 50-80mph 3rd gear pull of any production car (including the Ferrari Testarossa) in 1988.

 

Jim - sounds like a good time to video for an accurate number ;P
I want you to beat 3.80

 

I have a vdeo on one of those Hi-8 digital cassettes. You can see the speedo and watch the widshield jerk around to the left at 160 KPH (968 Euro cluster) on the dry track before I caught it. Ooops.

 

I would ASSume these were probably 0-100 or something and that was the time from 60-100, but not sure.

"I read once that the Porsche 944 Turbo S had the quickest 50-80mph 3rd gear pull of any production car (including the Ferrari Testarossa) in 1988"

I just read that today

 

I think these times are usually taken with a flying start so that you are already accelerating hard when the clock starts at 60 mph. I did a 60-100 run in 5.9 sec @15 psi with a coasting start at 60 mph, i.e. starting with no boost at 60 mph. It was also slightly uphill. I'm sure I could easily take another 0.5 sec off that time with a flying start @18 psi and on level ground.

 

This is definitely a good test for the car’s (engine’s) capability under somewhat realistic circumstances. There was a similar thread less than a year ago.

For original wheels and gearing 60 and 100 mph corresponds to 3970 and 6620 rpm in 3rd gear, 2940 and 4900 rpm in 4th gear and 2350 and 3920 rpm in 5th gear. Our typical HP curve is relatively flat from 3500 to 6000 rpm so in that case 3rd and 4th gear should show about the same results.

It would be very informative if the following information was included with the 60-100 mph time:
1) Gear chosen for each time posted
2) Flying or coasting start from 60 mph
3) Measurement method, relevant for accuracy. Could be a) wrist watch / speedometer reading, b) type of performance meter (such as G-Tech Pro and others), c) data logger type, d) Other
4) Approximate car weight with occupant(s)
5) Max boost observed
6) If non-standard gearing was used
7) Two way average (on same stretch) or one way measurements
8) Outside temperature, wind and elevation
9) Date of measurement
10) Latest measured torque and HP numbers and when acquired

Is this too much?

It would also be very interesting if somebody would keep track of the results in a spreadsheet, to be used for comparisons at the end of this thread and for future similar threads.
Any volunteers?

What are the stock numbers for the 951 and 951 S? Does anyone have road test info for the cars when new? Where do we fit in?!

I am sure the 60-100 time is the 0-100 minus the 0-60 times. Otherwise too unscientific.

 

The engine I just sold (back to the guy I bought it from) should have been good for about 3.11 seconds 60-100. This is from the previous (now current) owner, using a stop watch to time himself. The time was taken on a flying run, and I don't recall if his car was lightened or not.
