915 gearbox: Can you handle the truth ?

Not sure how your boast about how fast you're driving that "cabriolet" as "intended", compared to how slow i'm driving my coupe relates to this discussion, a downshift is a still a downshift, no matter the speed. I wonder if you burned rubber on your way down the road. Boy, am I impressed. The amazing thing about these cars is how much fun they are no matter the speed.
At least try to have some fun.
...and ya, it's just a cab.
A cab with a G-50 tranny so I really shouldn't be in the conversation, right? Tranny

Didn't intend to ruffle..... and obviously we are talking about two different driving scenarios. You drive your sports car in traffic where third gear is a mind numbing 40 mph... I drive mine as intended in box canyons and in the twisties where third gear hits the rev limiter at just under 80 mph with Butzi's full blessing. You come to a stop, I approach guys like you as a chicane in an otherwise straightforward course. Enjoy coming to a stop.

...and ya, you finally got something right too.....car looks great. Note the exposed T-bar ports...oh the huge manatee

Just noticed that your car is a G-50 so I guess the gearing may be quite different. In third my 993 G-50 (6sp) seems to redline at about 80 mph as well. BTW the third/fourth shift in that tranny happens to be sublime. Cheers

I prefer the feel of a cable actuated clutch over a hydraulic one. You can feel the bite point of the clutch disc so much better in a 915, and it comes in at a good, low point so that you can feather it in, and roll on the gas after it bites. When I took my clutch out at 350K miles, and changed the throwout bearing, the clutch looked new, and so did the flywheel. I ended up changing everything anyway, and gave away the clutch. It's still working on my friend's 911SC.
And the Wevo shifter is fantastic. Love the feel of it with the Wevo PSJ.

Rusnak, you are not alone in your clutch preference. Imagine how insane it was managing the solid linkage clutch on the '64 Barracuda I built in 1985-86. Step on the gas enough to torque over the 318 and the clutch would let itself out. It was on or off...there were no other choices.

You know, it would be interesting to post the shift points from the owner's manuals of a 915 and G-50 car, side by side. That would give some indication of gear ratios. The SC 915 is geared so that the engine revs are close to 1000 rpm higher at the same given speed. When I drove my '84 home, I was shocked at how much more torque it had, and at much lower RPM. It also felt much heavier, but the suspension settings were like night and day compared to how my SC was set up. The '84 felt like a rocket sled on rails, and the '78 like a tippy peaky 10-speed bicycle.
When I was test driving the '11 Cayman, I was wondering why 5th was only getting me around 85 mph at just over 4,000 RPM. Then I looked at the gearshift and it was like "oh, there's a 6th gear. Nice."

My car has a nice 3,000 RPM freeway cruising speed of right at 80 MPH where the Bisimoto Pulse Chamber does not drone and when cruising the car is almost silent.

And Doug, what do you mean, ran out of fuel pressure? This was a resto job, or???

Bring it!

Certainly it is. The problem is, 915 transmissions rarely have everything right. I've had two '86 915 cars and now an '88 G50. Both 915s were set up very nicely and the cars were great fun. But as good as the 915 can be, the G50 is a step up in terms of shifting action, and I prefer the hydraulic clutch. I agree that one should choose the better car overall and not fixate on 915 vs. G50, but if two similar cars are being considered, the G50 one definitely gets the edge.
