My 3.2 does 120mph at 6000 rpm.



Then I shift to fifth

My '8O SC has seen 135 mph in the middle of nowhere Utah no problem. YMMV

142. Redline and used my GPS to log the speed. That should land Ya in jail in any state. I was a dumba$$ for doing it on the public interstate in the first place.

My '78 with SSIs topped out at a corrected 140mph @ 6500rpm all day long. It did 140mph with the stock body and with the widebody conversion. The (stock) 915/61 gearing was perfect as the engine was running out of juice at the same time it hit red line.

I posted the following in an earlier thread on the same question:

My '77 S with a 3.0 will do exactly 146 real mph (GPS). In my case its most definitely rpm limited, not horsepower. If I wanted to go past the red line I know it would break 150 but I don't see the need to be that hard on my 30 y.o. car for the sake of 3mph. The car does this easily and while it feels a little light in the steering (no spoiler or tail) it isn't scary. Noisy, yes, but not scary. Based on my own car, I find the other claims of top speeds in this neighborhood totally believable.

I took my 996TT 175. My 80 SC about 120.

139. Ops tested in targa with 170,000+ miles on it.

Look at the transmission chart in the owners manual or in Bruce Anderson's 911 handbook.

140 + for my 79 SC... I backed off before it was done..

My SC did 132 indicated at Willow Springs. A recent GPS survey found the gaugeto be reading low by 10mph above 70.....

My new 964 speedo gauge is spot on....

My 1979SC, with 180K, has seen 130 mph and was short of being at red-line. I have read the Porsche speedometers read on the optimistic side.

I've read that the Porsche speedometer's read very "optomistic". With that in mind, I took my 1979SC to 130 mph and it wasn't at redline, but close.
