Re: s3 auto to manual conversion.

I think you would be disappointed with the manual 4 speed box. I had one in my car and in 4th it was revving too high for my liking at normal road speeds. In my case I didn't have the Overdrive box choice, so wound up fitting a Getrag 5 speed, which I like, but it did need an adaptor plate to mount ...

Re: JD40 Sprocket Retaining Tool

Yikes
how about one of those telescopic antenna like devices with a strong magnet on the bottom, some are stronger than others.
Then when you have lifted it a hooked wire may be able to be used.
Good luck

Re: opus ignition system

Hi Colin, As usual our resident expert Marek has posted the good gen. Here are a couple of websites I used to research when I was doing the mod on my car. The british vacuum site is useful to ensure you have the appropriate vacuum module. Following his advice I wound up using the 54405202 unit which...

Re: opus ignition system

Hi Philip
Isn’t the issue that, in your case, with vacuum still being provided to the advance capsule at idle, then extra advance will be provided at idle, which I believe is undesirable.
Well jaguar thought so which is why they set up the system to avoid this.
Cheers

Re: SU fuel pump electronic upgrade

I have just fitted Marek’s pump upgrade, and it’s working as advertised. His instructions are detailed with clear photos. It’s just as well I did the job at this time, as the points in the pump were quite pitted, the very symptom Marek’s mod is designed to reduce. I’ve cleaned them up and will be in...

Re: tyre pressure

hi Definitely have a look at your mounting of the underbody mufflers and exhaust pipes. Make sure the mufflers are right up in the cavities. And check they are the same oval shape as the OEM mufflers, I'm assuming someone has replaced them at some stage. The pipes where they go under the IRS should ...

Re: Series 3 Steering Upgrade


Hi,
I did the washer mod on mine, which was the jaguar solution to the oversensitive steering.
It does work very well, and gives a nice positive feel in the corners, as opposed to that driving on ice feeling.
However the rob beere solution sounds simpler and effective.

Re: Series 3 timing stroboscope

Hi I have found that due to the placement of the timing marks, the straight head type of light quite difficult to get in position to see the marks. I bought a similar one to this.

Hi guys If you check out the reopus website you'll find that it's no longer available. I fitted the SNG Barratt replacement HE system, and find it excellent. It does give you a rebuilt dizzy as well, which as we all know generally benefits from a rebuild. This kit is still has a retard vacuum capsul...

Re: Power steering problem

Hi
whilst you are on it, search the S3 forum for "pressure reducing washer". This mod is one of the best, and simplest, you can do for your S3. No more vague steering in the corners.

Re: sound of the v12

Hi Barry,
where was the HP increase?
Some have suggested that it is only at high revs, an area most of us are unlikely to use often.
If it was in the mid range it would be an advantage. I certainly would like more in this area for overtaking.

Re: Rusty fuel issues! Part 1

hi Catnip I see your carbs have the temperature compensator fittings on the side, the whiteish plastic cover. Did you overhaul or do anything to these? They can be a source of a vacuum leak. It should have a small tube out the top of the metal fitting for vacuum, if you haven't overhauled it, blank ...

Re: Rusty fuel issues! Part 1

Hi Catnip that little pipe under the carb is the vacuum pickoff for the vacuum retard unit on the distributor. It was fitted in an attempt to meet US emissions regulations. This was normally on a rear carb. I would block it off, and also the retard capsule on the distributor. you can tell its a reta...

Re: sound of the v12

Hi
Why doesn't someone publish the Dyno results, to prove the power increase?
In fact I can't understand why Mr Bywater hasn't done it to end the aspersions cast by some about his systems.

Hi guys here is a link to the sound of my car with straight through glasspack underbody mufflers, the same size as the originals, exiting into 52mm pipe with no rear resonators. This is stage 3 of Woolfi's ideas. Sounds great to all my mates, translate=(Friends), even my missus, translate = wife, lo...

Re: oil residue around petrol cap

Hi
Is the car burning oil?
I had similar issues before the rebuild of my V12. Oil was leaking into the cylinders and being burnt during trips. This left more of a sooty residue than oily, if you know what I mean. So an oily residue suggests a leak from the diff, or somewhere on the engine.

Re: sound of the v12

Hi guys Here's a pic of a 52mm straight through exhaust. You will notice I have done the Marek mod on the rear tailights, nice to get rid of the messy reversing lights. We did have to flatten the pipes where they go under the IRS to keep ground clearance. https://s2.postimg.org/jz8zm5yyx/IMG_0504.jp...

Re: Stromberg carb temperature compensators

Hi, I agree disable them. While you are at it also disable the bypass valve on the side of each carb. To do this just remove the vacuum source from the little pipe on the top of the valve and plug it. These units were only there for emission control purposes. Also I would remove the vacuum from the ...

Re: Timing chain - Setting the timing

Hi Pete
I know you don't want any special tools, but, the cam setting tool is as cheap as chips, and can be hired from the UK jag club, along with the timing chain setting plate.
This protractor is useful for getting TDC exact.

Re: sound of the v12

Hi
Lots of guys have modded their exhaust system to achieve a more sports car sound.
Try a search in this forum for v12 exhaust sound. In particular read what Woolfi, a German contributor, has to say.
Ive done mine in similar fashion but with no rear resonators, the sound is great.
