Is an 85 Carrera Peppier than 87?
i'm not sure if it's just in my head, but since i've owned my 87 i've also owned two 85's and for some reason the 85's just feel lighter, peppier, more responsive than my 87.
the 87 runs just fine. there is nothing wrong with it. i'm certain that at wot the 87 will beat or at least be even with the 85's. it does run strong. it just seems like in normal driving and zipping through corners and stuff like that the 85 is just spunkier. am i nuts here? is it the g50? is the 87 a heavier car?

The g50 cars are a little heavier but only 40 or 50lbs I think. I believe there is some difference in gearing, maybe that is the difference? Or a combination

Certain parts of the g50 do add some weight, but most of that can be replaced (i believe)to make the weight difference minimal. You have to assume that the newer the car, the more options it likely has. Compare the options of the 3 cars, also if they were euro spec can make a difference. Are any of them cabs or targas? Can also change things.

More likely it's an air flow meter issue. Even though they look identical and have the same part number, they react differently in the same car. I've installed different AFMs on my 86 and you would not believe it was the same car.

Later US market cars came with alusil cylinders. Although the factory claims the same power output as for nikasil, I don' believe it. I'm not sure of which years had the nikasil, except that some 84s did.

Gearing. I had an 85 and now n 87 and to blast away in second gear with the 85 was a blast!!
But.....overall the 87 is better.

Are you sure you are getting full throttle on the 1987? I know many that don't get there.
The flywheel is a little heavier - the clutch is a little heavier. But a really well running car - on both the 1987 and the 1987 will feel very similar. (well, besides the vague shifter on the 1985 and the hydraulic clutch on the 1987)

I noticed the same thing comparing my brother-in-laws 84 to my 89. I am fairly certain my car is running in top condition, including a Wong chip. I would say his second gear had more pull quicker and my third gear would run longer. Not that I would drag race but I think he would be quicker 0-60 and we would be pretty ever or I would win 0-100. His power also seemed to kick in earlier (3000 RPM) while mine really kicks in around 4000 RPM.

I was told by my tech that the gearing is a bit taller in the g50, so yep, you are giving up some feel. But as the others have said, you are getting a lot more in return.

i agree. believe my, i LOVE my 87. i figured it had something to do with gearing.
i've already gone through the afm thing. swapped it out and it was the same. i also did the swipe arm deal. also when i got the car the wot switch was not working. so yes, i've done all that. the first 85 also had 15x 7&8's. that car was super peppy and i figured it may have also been the difference in diameter of the wheels. but this one has the same 16's and it also seems to just get up and go with less effort. I do truly believe that my 87 will pull away from it though once the rpm's get up there. cashman's theory seems about right. the 87 does run hard. and those sport seats.....mmmmm............

If the 915 gearing is shorter than the G-50's which I think they are, that is mostly it.
Also, since the G-50 is stronger, you can expect higher parasitic drag further reducing tq/hp to the wheels. |

I might sound odd but back in the 3.2 era and after driving many new and 'breaked-in' 911's, this topic would often come up. One would sort of get that feeling of a cars lack of or or not performance difference. Side by side equal same year configured cars, you could sometimes sense it. I would attribute it to the hand built nature of the car and final tuning. Little things such as valve clearance or air adjustment could be all it is.
The question of an 85 to 87 might be a combination of the above replies but the later car is simply a bit more refined and with the G50 trans probably lessens the exhileration feeling... just a thought. Scott |
