This corner of my shed site is to share with you what I am currently working on.

Suspension Upgrade


Recently I have been making a few improvements to the rear suspension on the rally car. I upgraded the springs from 300lb to 380lb Eibachs and changed over from the Bilstein non-adjustable  shocks to Koni adjustable sport shocks so I could do my own fine tuning rather than having to send the shocks away for adjustment.


The parts are from Ground Control Systems in the USA. Their service and parts are of a very high quality and reasonably priced.


The car feels much better planted now.



Exhaust Tuning


The exhaust system I fabricated for the rally car works really well but there is a drone at certain revs which I would like to reduce. I used an app downloaded on my tablet and identified the culprit frequency to be around 170-200Hz.


I have fabricated a pair of ¼ wave resonators (you will need to Google this to see what I’m talking about but basically these are additional exhaust pipes with blanked off ends.) and am currently experimenting by altering the internal lengths of the tube - just like a trombone. Sounds weird but I think I have worked out the ideal length for the resonators.


The pipes work by cancelling the offending frequency. Works on the same principle as Helmholtz resonators fitted to many new cars.
















Rack & Pinion Power Steering Conversion


As mentioned some time ago, I have been intensively researching options for converting Morgans from steering box to power rack and pinion. With a factory manual rack and fittings costing well over $3000 I am keen to find an economical alternative with the same centre take off design as the factory setup.


I have now also received from the USA the power steering rack I plan to use on this project plus other Mogs if it works out well. This is from a mid ‘90s Front Wheel Drive GM car.


Yes, it is for a LHD but imagine if you flipped it and placed it in front of the axle (Morgan style) rather than behind the axle (GM style). Voila - you have a perfectly good RHD centre take off rack for your Morgan.


There will be a few mods needed to the fluid lines, radiator support etc. Once completed I do plan to write the whole process up so it can be replicated by Morgan Owners.
