Nobbie Posted January 4, 2021 Report Share Posted January 4, 2021 My PS hose was melted by my new exhaust manifold on a trip up to Moffat, so I had to complete the remaining 60 miles to Moffat and 200 mile return journey without any assistance. Generally no problem when driving fast, didn’t notice it on the motorway, but easy to get caught out on slow 2nd gear bends and roundabout/turnoffs when it really loads up.

Ninesomething Posted January 8, 2021 Report Share Posted January 8, 2021 A lot of the effort involved in turning the wheel on PAS cars with failed pumps is actually pushing remaining fluid round the system. Once there's no fluid in there it can be easier. I haven't tried this I was told. Link to comment Share on other sites More sharing options...

Jack the front of the car up and without the engine running it’s easy to turn the front wheels, so that does not seem to be true. Link to comment Share on other sites More sharing options...
RobScott Posted January 8, 2021 Report Share Posted January 8, 2021 It can be done, but whats the point? I have a 986 Rack, with a Quaife steering quickener, and a Cup Car electric Power Steering pump Works well Link to comment Share on other sites More sharing options...

BatKing996C4S Posted January 8, 2021 Report Share Posted January 8, 2021 From when a hose jumped off my rack and had to drive it home without can say it's not for the feint of heart. You I suppose might be able to get manual conversion so more turns of the wheel are required for full lock to make it slightly liveable but it's not going to provide you any benefit in the stock form on the track or road, forget road feedback you are going to be wondering if you can turn the wheel before you hit a wall. I may be exaggerating and it happened to me in my 996 C4S so wider front tyres and the AWD system to fight as well, but if you want the performance gain to take the load off the engine then electrification is the way to go as essentially the extra load on the engine is only put on by the alternator as the wheel is turned, the Porsche 996 GT3 RS in fact used this exact method using a TRW electric steering pump which happily is the exact same part a a Vauxhall astra one so can be purchased for only around £100 second hand or £300 new rather than Porsche Motorsports £1500 price tag for one. On my 996 I'm going down the route of electric power steering, you can order adapters for the high and low pressure line to 6-AN and 8-AN connectors from LN engineering, The 986 is a pretty good pick because you can buy the frunk trim for the European models with the brake fluid bottle on the right hand side and the pump can live behind it looking neat and still providing access to the bottle, there's a guy on youtube who's electrifying his 996 and has done a pretty good video on the implementation though I'd reccomend the LN engineering fittings and getting the rest of the power steering hoses and connectors from earls and you with have a system at least or if not more reliable than OEM. Another consideration is a 997 steering rack as I understand the part is interchangeable but has a variable ratio, the idea being the beginning of a turn from straight is slow so less impact on the wheel form bump steer and more precise control while holding the car in a straight line while maintaining the ability to make quick hard turn, best of both worlds. May make for a better manual experience by making the wheel initially easier to turn from straight when pulling away since as when you have more speed with a manual rack the wheel is easier to turn. Won't help much however for slow manoeuvres such as parking at which point prepare for an impromptu muscle workout. Link to comment Share on other sites More sharing options...
½cwt Posted January 8, 2021 Report Share Posted January 8, 2021 I believe it was back in 1991 at Williams in F1, the driver wanted power steering. Patrick Head offered the power steering but they'd have to lose 7kg in weight to compensate. Guess what both drivers (one was Mansell, the other Patrese) lost the weight. Why would you want unassisted steering in a road sports car? Is the power drain really that much? If so buy a 986 S (but @cheddar you've always said you don't need the extra power...), With the increase in steering weight you are not going to get more road feel unless you go for a slower ratio rack with more turns lock to lock which would defeat the purpose of the quicker PS rack to allow faster steering inputs. Final theory, the other half has taken a shine to the car and you want to make it heavier to driver to stop her pick up the keys? Can't help thinking you'll hate it. After seeing my driver on a couple of occasions have to driver most of a stage in an Escort Cosworth on tarmac after PS failure with a split hose so no hydraulic resistance, it looked like he was going to die when we got to the stop line and it certainly wasn't quicker or a more rewarding feel.
