Fletcher..

Any idea where I could find performance numbers, 0-60 times, 1/4 mile times, etc. for 964's (C2, C4, RS America). The factory numbers would be fine or any magazine numbers would work also. Thanks for any help you can give me.

I believe the factory 0 to 60 number for a 964 C2 is 5.5 secs. Most magazine tests have been in the low 5 second range. A great source for this info is the 911 Gold Portfolio for 1990-1997. It has magazine reviews of 911's from those years, including performance numbers, and can be bought from Amazon.com.

Here are a few numbers from my 1990 911 Carrera factory brochure for the US market:

C2
0-60: 5.5 sec.
1/4 mile: 13.9 sec.
Top Speed: 162 mph
Coefficient of Drag: .32
Fuel Consumption: 16 City / 24 Highway
Curb Weight: 3031 lbs (C2 w/5 speed)
HP: 247 @ 6100 rpm
Torque: 228 @ 4800 rpm
Compression Ratio: 11.3:1
Wheelbase: 89.4"

C4 (Differences only from C2)
0-60: 5.7 sec
1/4 mile: 14.1
Fuel Consumption: 15 city/22 highway
Curb Weight: 3252 lbs

I've also read that the C4 did not have any noticeable change in 0-60 times from the C2, but my brochure does list a difference.

The RS America specs that I have come from Road & Track, September 1992.

(differences only from C2/C4)
0-60: 5.3 sec
1.4 mile: 13.8 sec
Curb Weight: 2995 lbs
Fuel Consumption: 15/25 mpg

Hope this helps,

Well, I got some good news and I got some bad news about the RS specs.. First, the good- I just ordered the original brochure (oh im soo excited).. Bad news it'll be about a week before I have it in my hands so we'll have to wait a little while.. But once I get it I promise to post it..

Where do those MPG figures come from. I've driven my '91 C4 in both city and highway conditions and have YET to see mileage figures anywhere near that low. For "about town" driving I'm typically getting 18-19 mpg.

Just thought I'd throw that out.

Thanks all

Does anyone have a curb weight on the cab?

The very first R&T review listed the 0-60 for a C4 at 4.9 sec. but everyone else seems to list it as 5.7 I'm not sure what they did differently. Have the orginal article scanned on my computer at home and can post other test data they list too if anyone is interested.

Plenty of 964 0-60 and 1/4 mile times measured by a G-tech in this threadG-tech

agentpennypacker: when I corner balanced my 92 cabrio with no driver in it, just a touch less than half a tank of gas, all tools, spare, etc., top down with the wind blocker screen and the boot cover, and a stereo with a subwoofer (otherwise totally stock) it weighed in at 3230 lbs.

My 1994 C2 owner's manual lists the 0-60 as 5.4. Odd that the number quoted is .1 different from the 1990 manual.

I have a couple of magazine reviews against equivalent cars in 1990 on my website, they show a fairly detailed breakdown on the stats through the gears and speed ranges.

Chuck, no not really. There were engine part changes made to the 91-93 models that can account for the improved 0-60 times. One of which was a change to the more desirable plastic intake manifold, which reduced weight on the vehicle as well as decreased the air temp going into the engine. It also proved a more efficient path for the air to flow, with less resistance than the old cast aluminum manifold.

Depending on which magazine you read the test can vary by like a 1/2 second. This has to do with equipment, temperature, altitude, where they test it, road surface, etc.

On thing that I remember that was pretty consistant is that the RSA was about .1 faster then a C2. The C2 was about .1 faster then a C4. This all had to do with weight I believe.

Hope this helps.............Flagg

Is something my mechanic or I can fit to get those benefits?
