In Defense of the 928...

Just ran 6 runs in the GTS on the GTech meter. I don't have the software loaded on this PC and won't have a chance to do so until later this week but here are some of the numbers of my best run. The first few were much slower. It took me a few tries to get it right and then the local cop saw me so I high tailed it home. BTW outside temp is 68 degrees I would say close to 50% humidity but just guessing.
Stock 93 GTS with RMB no other mods 58k miles.
Rated Hp at 60 mph 365bhp
240 average HP
0-60 @ 5.35 seconds
0-100 @ 12.80 seconds
1/8mile 9.05 @ 83.8 mph
1/4mile 13.75 @ 102 mph
I have litte experiance using this device so I don't know if corrections are needed or how accurate the info trully is but it seems about right based on my seat of the pants feel vs the turbo 3.6 which does 80 in about the same time or less than this does 60 in.
Don't know if it proves anything and don't get me wrong I appreciate the link to the site. However, it is tough to use any data especially if dated. So much has changed over the years and comparing yesterdays numbers with yesterdays tires and electronics are not always comparing apples to apples anymore with the newer technology of today.

You have asked me to prove the numbers on that site wrong. This is exactly as if I, having posted a 'fact', asked those questioning my statement to prove me wrong rather than proving to some level of satisfaction that I was correct.
I cast doubt on your use of that site as a source of data for comparative purposes.
I wrote above:
"How is it that cars with more horsepower and shorter gears show slower 0-60 and 1/4 miles times? "
You yourself posted numbers that cast additional doubt:

1) The numbers you posted are different from the numbers on the site.
2) I pointed out a logical issue with the last three 928 numbers from the site.
This is sufficient to point out to most that the numbers from that site - while they may in fact be 'fact' - cannot be used for purposes of blind comparisons such as:

From the Porsche Technical Specifications:
'87 5-speed: 0-60 - 6.3 sec, 1/4 mile - 14.1 sec
'90 GT: 0-60 - 5.8 sec, 1/4 mile - 14.1 sec
'93 5-speed: 0-60 - 5.7 sec, 1/4 mile - 13.7
'87 5-speed: 0-60 - 6.3 sec, 1/4 mile - 14.1 sec
'90 GT: 0-60 - 5.8 sec, 1/4 mile - 14.1 sec
'93 5-speed: 0-60 - 5.7 sec, 1/4 mile - 13.7

So my car seems to be pretty much on spec. I think if I were running the MXX3's that originally came with the car and without the short shifter, I think the 0-60 time would be closer to the 5.7 specified by Porsche. The PS2's do not slip compared to the MXX3's and a slight decrease in shift time would account for the .35 second faster 0-60. The other thing I did not mention was that after the 1st 1/8th of a mile the road started to sloap up hill a few degrees which would acount for the slightly slower 1/4 time. Pretty cool that after 12 years and precisely 58k miles the car is still as capable as it was new.

Actually it is .75 seconds for both the 0-60 and 1/4. Must have been an auto.

These "number" comparisons do not work in relation to Corvettes as they offered different gear ratio packages. Low ratios will always dramatically increase 1/4th et time, but severely limit top speed. Long gears make for high top speed, but lower acceleration.
Thus, comparing a 180+ mph GT to a 130 mph low ratio Covette is so much nonsense.
And obviously so.

When was the last stock Corvette limited to 130 and how many 180 mile GT are there?'s You are heading right back to the 10 to 20 car length arguement. When was the last performance auto limited to 130? The most recent are probably limited by their ECU's not gearing.
