PS: wrt the maximum torque the allen screw can bear... well, at a certain point the allen key started to turn in the head of the screw :sad: despite a new screw and a new key... :banghead:

Re: Lower Steering Column Yoke - updte

Hello all, just a quick update: I've extracted the steering column from the car in order to inspect the splines on the yoke: - foto 1 shows the splines of the lower yoke: https://i.postimg.cc/SKQf8cNw/lower-yoke-splines.png - foto 2 shows the yoke on the upper-end of the steering column: https://i.p...

Re: Lower Steering Column Yoke - bit of progress - and a question!

Hi there, I started working on getting rid of the loose fitting of the lower steering yoke on the steering rack pinion. Stage 1: remove the old allen screw. I managed to remove the allen screw of the lower half of the yoke (the upper half of the yoke is integral part of the steering column, remember...

Re: Lower Steering Column Yoke

Hello Dave, you wrote "good fit", this means you cannot turn the yoke even if the pinch screw is away? Could you do me a favour and measure the outer diameter of the pinion and the inner dia of the yokes? I cannot turn my yoke by hand but it is rocking up and down on the shaft (and ofcourse sliding ...

Re: Lower Steering Column Yoke: anybody using an aftermarket yoke?

Hi there, thank you for the input sofar. Although I am a bit reluctant to drill or saw into the knuckle... Dave's approach to buy joints that have the recessed bolt and to use the lower half of it, doesn't seem to work out for me because the "usuals" don't offer that part... But they offer a repro p...

Re: Lower Steering Column Yoke

Hello Dave, I had managed to buy a couple of joints which had the recessed bolt section on one end and the conventional though bolt on the other. This appears to be a viable way! From your observations, where does the play come from: the splines on the yoke or on the steering rack pinion? The silver...

Re: Lower Steering Column Yoke

Hi there, my yoke has exactly the same issue! The splines don't really show excessive wear, so I would assume that the play was tolerated during manufacturing period. In any case, a fellow member from "the other forum" pointed to a similar issue with MGA steering yokes and a service bulleting from t...

Everything we know is here: http://forum.etypeuk.com/viewtopic.php?p=2553#p2553
I simply cannot wrap my head around the fact that just a coil pack and an ECU achieve a performance gain like that. Even compared to 123! Has somebody an understanding how that can be?

Re: rolling road figures: ECU users here?

Dan. That hardware kit is still available. The kit was originally destined to be a complete turnkey kit with ECU and loom, but we dropped that when we stopped ECU production about 3 years ago. Hello, did you adapt the software/parameters of the ECU to the XK-engine, or was it more or less standard ...

Re: rolling road figures

A few years back, when we were still in the ECU business and had our own rolling road, we did some back to back testing on a standard 4.2 Etype , mainly to see how a well mapped ignition system affected the torque, but it also shows a stock SU equipped power curve alongside the same engine fitted w...

Re: 3 SU-carbs: oscillating AFR-value

Hello there, upon Mr Heuers recommendation I checked my fuel pressure, which is ca. 5 PSI (ca. 0.34 bar): https://i.postimg.cc/mr6Z6zGC/pierburg-fuelpressure.png I've replaced my Pierburg pump with a new SU pump, and installed a fuel pressure regulator between filter and carburetors. I set the fuel ...

Re: 3 SU-carbs: oscillating AFR-value

Hi Steve, I've got the 123jag distributor (with curve F) which has no advance below 1500 RPM or so. I gave wrong info from the top of my head, sorry. I am using curve "0". .....also any of the settings give 12deg advanve between 500-1200rpm What I meant was: the 123 doesn't add avance degree to the ...

Re: 3 SU-carbs: oscillating AFR-value

Hi Andrew, you are right: my data acquisition does not calculate the rolling average over the sensor values. I could do that and would achieve a smooth line of AFR/lambda values. The problem is that I don't know if a) these oscillations are a data acquisition artefact, b) a symptom of a problem in m...

Re: 3 SU-carbs: oscillating AFR-value

I noticed an immediate improvement at idle with a far less 'splashy' exhaust note meaning a less rich mixture. The car revs perfectly through the range, even with my modified engine, with no misses suggesting 2 psi is ample pressure for the SU's.
WOW that sounds promising!

Thank you, Mr Heuer :-)

Re: 3 SU-carbs: oscillating AFR-value

Hello Christopher, thank you for your feedback! The lambda-value oscillation range is around λ0.09 (between λ0.84 and 0.93), i.e. AFR 1.3 (AFR 12.35 - 13.67). Interesting that you come up with the float chamber levels as probable suspect. I am using a modern (non su-type) fuelpump, which might build...

Re: 3 SU-carbs: oscillating AFR-value

Hi Marek, thank you for your input! The AFR and rpm will move if either the air or the fuel quantities move about, and/or also if the amount of advance is moving. A flattish advance curve with a dip at idle will tend to stabilise idle. I've got the 123jag distributor (with curve F) which has no adva...

3 SU-carbs: oscillating AFR-value

Hello, I've fitted 2 wideband oxygen- ("lambda")-sensors into my 4.2L. The sensors are located between engine and main silceners. The sensor-controllers are from 14point7. My engine has been rebuilt to standard specifications (from VSE in Wales) and comes with a 123jag-distributor. Exhaust and carbs...
