Scott,
Yes, given that you will not lift the whole car off the ground at once. Lifting the whole of the rear of the car off the ground should be about 850kg tops.

I love my G50, the 915 is so slow to shift without abusing it IMO.

Hi Chaps,
I haven't responded for awhile now , but this gear box subject interests me .I also have a 915 box in my 1986 supersport , which after driving a modern company car ,i wandered what i had bought.I then tried a different approach reading various suggestions on getting the best out of the quite old design.The thing is you don't know how a gear box has been treated before your ownership.I then set about bringing certain items up to spec. changing the bushes, replacing the oil to swepco 201 boy does it stink !! Then adapt my driving style.As mentioned to a more slower change. I was then rewarded with a smoother change and amore enjoyable drive. I think the secret is to keep the engine revs up so as not to lose momentum whilst changing gear at a more leisurely pace, blipping the throttle on changing down.

I think I have got good experience with changing gears due to driving work vans. I once drove 12 miles including starting off, reverse parking etc etc. all without using the clutch as an apprentice who had recently passed his driving test did not think it was possible! Heel and toe definitely helps and the pedals are great for this in our cars.
Do you have an old banger or a company car you could practice on not using the clutch while changing gear?
Also, the fact that I have seen & played with the internals has probably helped too [

This is my point exactly and thats why cars fitted with the 915 box need careful slower changes ,which in return require more revs.This might explain why 915 box cars feel quicker.I know the obssesion folk have with power to weight ratio but the weight of a gearbox, would hardly be noticeable.I know the reputation the 915 box has and the minor adjustments i have done make it easier to live with.[clutchless changes, it makes me cringe at the thought!!]
No clutchless shifts in any of my 911's!
Personally I think the Porsche 915 is junk compared to the Getrag G50. I am sure the 915 was excellent at the time of it's launch.
The only good thing about the 915 is the location of reverse. The location of reverse in a G50 is near first gear & I think that location is stupid in any car IMO.

Hi Bert - where do your weights come from?
IIRC the Coupe weights from the red book are 1210/1250kg for 915/G50 respectively. In the real world with all fluids and a few options (no air con though), a G50 3.2 will weigh around 1320kg.
What is the difference between a G50 and a 915? Well, I posted the following on IB.com -
The G50 has a bigger hydraulic clutch (915 is non-hydraulic) - 240mm vs 215mm, more modern synchro cones and is internally gated. Its a bigger gearbox and as std has a rubber centred clutch. It weighs 45lb more than a 915 (27lb for the gearbox and the rest in clutch, pressure plate and flywheel - as measured by Tyson Schmidt on Pelican - and can be reduced to about 14kg difference with aluminium pressure plate and spring centred clutch). It feels more "modern" to use because of the clutch and because of the internal gating. Many 915 owners seek to attain the same level of precision, the gated feel and springing to the 3-4 plane by adding Wevo or other improved components. Many 915 owners post questions on how to "improve" the quality of their shifting whereas G50 owners virtually never ask the same question. In most respects the same G50 architecture took Porsche through the 964 and 993 range. Its sought after by builders of high hp cars like Ultimas. G50 is generally regarded as a better gearbox with a better shift action but some prefer the 915 for reasons such as weight or character or the way they feel. Neither will compare to an MX5 or 987/997/996 gearbox for slick, positive, riflebolt (and other roadtester adjectives) shift, however, usage being equal, a std 50,000 mile G50 is closer to this ideal than a std 50,000 mile 915 in the vast majority of cases.
Cheers,
RB
My '84 MY carrera sport coupe weighed in at 1160kg with just over half a tank of fuel. No AC or electric seats in this early 3.2 coupe.
