DIY Modification to Improve Performance and Fuel Economy of AJ16 and AJ6 Engines
#461
I am extremely sorry that you have had a bad experience with one of my brackets. I have checked all of the remaining brackets that I have in stock from the current batch. As you say, the sensor hole is undersize. It should be 17mm, but it is only 16.8mm on all the brackets that I have checked. Thank you for bringing this to my attention. Please contact me directly and I will arrange to reimburse you for the cost of your broken sensor. Please also return your faulty bracket and I will send you a replacement. In future, I will implement a 100% check on the hole size of all brackets prior to shipment.
To anyone else who has recently purchased one of these brackets, please do not try to force the sensor if it does not fit. Please return any brackets with undersize holes and I will exchange them for brackets which have been 100% checked for size before shipping.
Once again, I sincerely apologise to anyone who has been inconvenienced by this quality issue. This is the first time we have had any quality issues with these brackets in a production run that now totals 500 parts.

I fitted uprated front sway bar bushes, but I have an alternative suggestion to uprating the bushes in the drop links, as we have already discussed off-line. I replaced the standard Jaguar drop links with ones of my own design. These use high spec spherical bearing rod ends joined with a turnbuckle. The rod ends are enclosed in rubber boots. I use conical misalignment washers to allow the spherical bearings to fully articulate. The combination of the rod ends that I selected and the misalignment washers very closely match the width of the standard drop link ends, so the standard bolts can still be used. I don't find that the use of spherical bearings has any negative effect on ride quality. However, it significantly increases roll stiffness of the car by eliminating all the compliance present in the bushes in the standard Jaguar drop links. I would thoroughly recommend this modification if you want to improve the handling of your car.

hi, i'm hoping to get one of these but i'd like to ask if it's possibly to use less metal and make it lighter?
the main body of the bracket, around the bolt holes, have a sharp corner, could they not be rounded off? what about the metal inbetween the two bolt holes, could we narrow that and introduce a waistline?
i appreciate this is a very insignificant point but i think we could shave off some metal here! (obviously we cannot weaken it).

My bracket weighs 60g and a standard bracket weighs 30g. My brackets are machined from a solid block of aluminium. I needed to create the shape with the minimum number of surfaces in order to minimise the machining time. I could design a bracket that looked more like the shape of the die-cast standard part, but it would cost very much more to machine each one. I don't think anyone would consider it a good weight / cost trade-off.

Dear All,
I just collected from the machine shop the new batches of revised crank sensor brackets for replacing both the EBC1253 and EBC5017 designs. These brackets are for early AJ6 (post 3.6L engine number 108834) and late AJ6/all AJ16 respectively. The changeover on bracket design occurred on late 3.2L/4.0L AJ6 engines at engine number 161586. If you are interested in one of these brackets, then please contact my wife Helen using her email helenstodart@gmail.com.
Thank you all for your continued support for my revised brackets.
