K&N Q&A: 'SUs for V12s', 'Bung it here...'

Q Burlen Fuel Systems do a 2in SU conversion for an E-type V12 at the cost of £800, do you consider this to be a worthwhile conversion? How beneficial would it be? And what differences would it make to the performance and the

mpg? Andrew Wilcox

A The general consensus of opinion is that the carburettor conversion is a worthwhile modification for the V12 engine. The original Stromberg carbs were fitted to help clean up the emissions, necessary for the American market where a lot of V12 E-types were sold, but in time as the cars clocked  up  higher mileages, wear in the carb  bodies  caused them to go out of tune even    when    new diaphragms were fitted, resulting  in  the  V12 engine not running as smoothly as it should.

Faced with the cost of replacing the Stromberg carbs with new or fully rebuilt ones, it would be wise to consider the conversion to SU carbs as an option.

 

The conversion kit supplied by Burlen Fuel Systems is well engineered, fits properly and, after careful setting up and balancing, the engine does appear to run more smoothly with a slight increase in performance compared to the Strombergs.

Will Caradoc Hodgkins is one owner of a V'12 E-type with first­hand information on this conversion. Having purchased the kit from Burlen Fuel Systems and fitted it himself, he commented that he found the installation instructions to be "a little complicated for someone fitting it for the first time", he also had to obtain the essential clutch master cylinder adaptor required to give clearance to the offside carburettor, which is also available from Burlen.

 

Once fully installed, he reports the engine started and responded well to adjustment of the carbs. After driving the car for some miles he feels that the conversion is a worthwhile modification, performance slightly improved and the 'flat-spot' has completely disappeared at mid-range. Also MPG seemed slightly better overall.

Our thanks to Will for this information

 

Bung it here…

 

Q I have just finished re­fitting my reconditioned power steering rack to my 1972 V12 and have this plastic bung thing left over. It is about 11A inches across the top. I vaguely remember taking it off from somewhere but I cannot remember from where. Any idea? Mark Griffiths

A I have spent some time checking through all the parts lists for your 1972 V12 to try and find the part you are referring to. I feel sure that it is nothing to do with your power steering system or from any wiring grommet holes in the bonnet. My best guess is that this blanking grommet has come from the access hole in the front timing cover (just below the right-hand cylinder head), where a special tool is inserted when working on the timing chain adjuster. It should

have a metal plate from a nearby stud to prevent its loss, so maybe the one you have found is an old one dropped after the replacement was fitted at an earlier time. It is worth having a close look to check as, without it, oil would certainly leak out!
