Re: S3 Heater Install
When the flap is vertical it blocks all air into the matrix, result is that all air from the fan is dumped into the engine bay and no air can flow into the cabin. Why would an owner want to have this "feature", which, in my words, will suck air in via the bonnet duct, through the fan, then dump it ...

Re: 6 cylinder in a series 3?
installing a 4.2 into an existing V12 car? I'm really interested in hearing the motivation for doing so. WHY??? A V12 has only two main issues that need attention: Ignition; Cooling Both sorted very easily, and rather inexpensively, with definitely far less effort than would be required to fit an X...

Re: S3 Heater Install
I've never quite understood the purpose of the flap being controlled by the L shaped lever with the spring... It seems to give the occupants of the car the choice of drawing air via the bonnet duct or ... drawing air from the engine compartment. I can understand the benefit of drawing air from the n...

Re: Engine Tuning issues Early UK Series 3
i would remove air filters and rev it up while watching to make sure that the slides are all lifting and topping out on full throttle I don't think one should expect full lift of those air valves without the engine being under significant load and at high revs. Never tried it myself though, so I do...

Re: Engine Tuning issues Early UK Series 3
Does the Pertronix 9LU-1122A Ignitor II work with the Reopus Amplifier or is it removed and the module does all the work? The Petronix is an all-in-one unit with pickup and ignition amp elegantly all inside the dissy. Only wires needed is Ground, 12V and Coil-. Only other item needed is the coil. O...

Re: Engine Tuning issues Early UK Series 3
Ignition system is a ReOpus unit, believed to be good. You can not assume the ReOpus to be good. My own 2+2 was fitted with ReOpus when the car still belonged to my friend. The car had a persistent misfire. Which could not be cured with timing setting, carbs setting and clean plugs. He has a electr...

Re: Needles for SU carb conversion
if I set the AFR to give a good AFR on the road (13.5:1), then it is massively rich (10:1 and black smoke) at idle. I don't know what exactly "on the road" means but 12.5-13.5 is what you should have at full throttle conditions and off-idle. For steady cruise, level road situations you should have ...

Re: Worst plugs ever seen?
2SO DE-COKES a non-cat, non O2-sensored engine.... among many other advantages. I'll elaborate: Using two-stroke oil (2SO) as an additive (approx 200:1) on a non-cat, non-o2-sensored petrol and diesel engines does many good things, the main ones being: softening and eventual removal of the carbon d...

Re: B W 12 Automatic gearbox
both mechanical and vacuum advance. 1. Vacuum ADVANCE? Are you sure? 2. What ignition system does it have? 3. Are the carbs balanced? (Using a proper air flow measuring device? Balancing by ear is, IMO, NOT balanced) If not balanced properly, you could have it idle at the desired idle speed with on...

Re: Hot Running Issues
Thanks Phillip. I have moved the amplifier to the front of the picture frame as Rob advised and so far, it looks like it has resolved the issue but I will take it on a longer run to get a bit more confidence. I strongly recommend you replace that OPUS anyway. It is NOT a good ignition system in man...

Re: Changing coolant V12
0. Is there a simple way to analyse whether the anti-corrosion additives in silicate cooling water (that is still clear and of blue-green color) are still effective? The total amount of cooling water in the V12 engine is approximately 20 litres. 1. How many litres does the "small" cooling water cir...

Re: Hot Running Issues
If the issue is not OPUS (and that would be my first guess also) then have a read of this: https://forum.etypeuk.com/viewtopic.php?f=6&t=16143&p=132421#p132421 There is a very cost effective upgrade for OPUS in my opnion: https://forum.etypeuk.com/viewtopic.php?f=6&t=18921&p=157064&hilit=pertronix#p...

Re: Air Cleaner Plumbing S3 V12
I know that when I eventually fit the air cleaners the long one will attach to the front of the unit which controls the flap and the short one will attach to the RH rear inlet manifold and the same on the LHS equivalent. Hopefully so far I am on the right track ?? This is correct, yes. You can veri...

Re: Etype V12 Thermostat Recommendation
The manual states 82'c thermostats. You want a thermostat which opens out far enough to let it's bottom perch to block off the bypass.

Re: Ally rad and fans, Radtec, NAR, other?
Both my S3's are running with alu radiators made by a small radiator service outlet in a small town called Knysna in South Africa...
