Power Steering Conversion
Does anyone have experience with EZ Electric Power Steering for classic cars which don’t have power assisted steering? The firm is located in Holland and have agents throughout Europe incl. UK. They manufacture a conversion which is totally electric and can be fitted to the existing steering column. This power assisted steering is proportional to speed so that maximum assistance is obtained at low speed and zero at high speed.
Kits are available for a range of cars but not yet for Bristols. I saw this system at the Bremen Classic Show the other day and the guy said that they would be very keen to develop and fit one to a Bristol at no additional cost over the standard charge. This seems to be a very worthwhile addition for those of us who are no longer quite so strong in the shoulder and should improve ease of parking and manoeuvring considerably. I shall certainly consider it for my 405! Richard |

For quite a while now I have been reading about how the electric power steering that is fitted to a Vauxhall Corsa / Fiat Punto etc ,is being retro fitted to a lot of classic cars and rally cars. I have found someone that is confident of fitting the system to a 408. Has anyone already done it yet to any Bristol ?
I notice that Aston Workshops are offering the same system for a DB5 for £3500 !! It shouldn't cost any more than £500. 12" of column space is needed and the amount of power assistance is controlled by a rheostat. What I like is everything still appears standard and the steering would still work even if power was lost. Greg |

The guy from EZ at the Bremen show told me that their system had not yet been fitted to a Bristol. But they had had an enquiry from a 408 owner in Berlin
The EZ system costs about 2600 Euros ie. about 2300GBP for a MB 190SL including installation which is supposed to be done by a recognised workshop. Quote:

EZ
EZ, like the others I have seen use the Vauxhall Corsa unit. I have bought two of them tested from ebay £80. To go with the unit you need to buy the box of tricks which plugs into where the ECU connection would go on the Corsa and combines with the power control knob ( about £30 ) .Then , as you say, it's finding a competent experienced engineer to fit it. The guy I have found in Lancashire has done loads of race / rally cars along with many classics but no Bristols yet.
I was hoping not to be the first ! I am going down the route of using a second hand 407 / 408 column so I can swap it back if I am not happy for any reason. He tells me that everyone has been delighted so far. Greg |

The other thing to note if considering electric power steering is the need to convert to negative earth and fitting an alternator due to the units requiring a 45 amp supply. I used the superb single wire alternator from Martin Barnes at ACCS. 100 amp I think in either classic black or chrome. Or alternatively you can have an alternator built into the body of the existing dynamo. Greg

Power steering electric conversion
Please bear in mind that the gear ratio of the non-power steering systems is much lower than for the powered systems. A 408 needs many more turns of the steering wheel lock-to-lock than a 409 with PAS. So it may be nice to have the assistance for parking, but once the car is rolling along, it will probably make the steering far too light.
|
|

Yes it's a good point - the kit comes with a knob to adjust the strength of assistance. It would be good if it could be designed to turn off when second gear engages and back on again for reverse and first. The guy that fits a lot of these tells me that most people find a setting that suits all !
I know of two people interested because of reduced strength due to disability. Is it something many Bristol owners would be interested in ? I have never driven a pre 407 Bristol but I believe the steering is light. Greg |

I wouldn't say the steering of my 405 is "light" but probably typical for its time! Certainly I can live with it as is but with increasing years it becomes more of a struggle to manouerve into tight parking places. Certainly my wife cannot drive it but with some assistance she might. I have asked EZ Power Steering to give me a quote and will report back. Incidentally they say that positive earth is no problem.

Another company called Pajoe have a electric power steering system. Below are the companies that fit their system. Obviously more popular than I thought !

Power Steering Conversion
Hello Greg, it was me who asked them because my wife does not like to drive our 408. They said they would try to convert the car at costs of around 4000- to 5000¤. Maybe we sell the car and look for a later 411. Hans.

Like the 408, the R-Type has beautifully designed steering, so that above circa 4 or 5 mph it is as light as a feather, but shuffling round carparks, well that is another matter. George |

ACCS has just completed an electric power steering on a 408. I beleive that the speed sensor works off the prop to cut the assist at around 45 mph. The original steering wheel remains and looks completely standard.

Power Steering Conversion
Hi Greg, interesting to hear about the conversion on a 408. I just had a nice tel conversation with Mr. Silverton from Bristol cars and he said that the guys from Holland who do the electric power steering were in London and they found out that it would be impossible to convert the early V8s - 408... If a conversion is possible does it make sense to put in a new steering box if there are some tolerances? Thanks Hans

Power Steering Conversion
I wonder what would happen if I install an electric power steering and my steering box has some tolerances - would this increae the effect - I mean will the tolerances becoming stronger? or just the feeling of the tolerances? I hope I could explain myself. Hans

Can't you just "upgrade" a 408 to PAS using the same components as Bristol on the 409 Mk2 ?
Given that the chassis is the same and engine is essentially the same I can't see that it would be such a big deal, but maybe I'm missing something. |
|

All I know is it is much more complicated than you would imagine to use later steering components on a 407 / 408. Maybe because the engine is located in a different location. I know that ACCS would have tried it if it were a straight forward solution and BCL told me it would cost £15 k ! EPS also has the advantage of keeping the car looking completely standard.
