Russ Posted 13January, 2015 Report Share Posted 13January, 2015 okay, so it's time for the SDL (Sportomatic Defence League - which I think consists of SteveF and myself) to have a thread for the love of all things Sportomatic, In line with the Tiptronic thread Manual Cover for Sportomatic (before it was an additional page or 2 in the owners manual) Diagram of how Sportomatic works (missing the coverage of the microswitch in the base of the gearstick to actuate the clutch): It did once win a race too! So you can't say it's not a real Porsche! - The 1967 Marathon De La Route, a 911R Sportomatic with Vic Elford driving (the current whereabouts are discussed here - http://www.early911sregistry.org/forums/showthread.php?67230-Sportomatic-911R-Whereabouts&s=90702095ecc5ddfc9d2b49858bc0a040): and below are the videos that got me into my car in the first place (I watched all these the night before I bid on my car) https://www.youtube.com/watch?v=Vhv5ITsVHLQ https://www.youtube.com/watch?v=Pd_KA93bGe4 Link to comment Share on other sites More sharing options...

Russ Posted 14January, 2015 Author Report Share Posted 14January, 2015 My dad had a '76 semi automatic beetle for a while, It was great fun to drive - it's running around in a light green with an oval window grafted into it The best thing about the VW system is that it's compatible with the 905 Sportomatic (180mm clutch - the 4 speed in earlier cars based on the 901) Unfortunately the later model 925 Sportomatic (3 speed, based on the 915 is a 190mm clutch and hard to find now) Link to comment Share on other sites More sharing options...

I was reading somewhere that only 2% of 911's were Sportomatic (I wonder what that number is now after a lot of them have been converted) Must be because it's a Targa ..... Can we please keep this thread to constructive information about Sportomatics? Link to comment Share on other sites More sharing options...

I was reading somewhere that only 2% of 911's were Sportomatic (I wonder what that number is now after a lot of them have been converted)Contrary to the fun both me and other members here make of the Sporto's, I honestly find them a unique part of not only Porsche history, but automotive history .....I've always been one for originality and for keeping things as "the factory" intended .... and while I understand why some owners change them to a 915 box, it's a shame they are being made obselete through this change..... I think that you may be right that "one day" they will be sought after as a special slice of Porsche history .....As Forest Gump so famously said ..... that's all I have to say about that .....

Coastr Posted 15January, 2015 Report Share Posted 15January, 2015 Hang on...that says just put it into 'D' for drive. How does that work? Does it just stick it in second and let the torque converter do all the lugging? I thought they were just a clutch less manual? Educate me, clutch less ones.

Russ Posted 15January, 2015 Author Report Share Posted 15January, 2015 it's a manual gearbox, behind a clutch and a torque converter, the clutch is vacuum operated by a micro switch on the gearstick. The torque converter is in the bell housing, the bell housing then comes off and the clutch is behind that you still have to change gears like a normal manual (OR you can drive around in D all the time but it's not fast) and just stop at traffic lights and drive off in gear.

SteveF Posted 15January, 2015 Report Share Posted 15January, 2015 I find that around town I generally use D (where second gear sits on the gear stick) and D1 (3rd). I only really use L (1st) when starting off on hills and D2 on the freeway. The trick is to time the gear change as sometimes I find that the clutch disengages quickly whereas other times not. A year on I am still getting used to this car but loving every minute of it. Link to comment Share on other sites More sharing options...
