Cooling Improvements

After my cooling and oil temp/pressure concerns on the way home from Stoneleigh I took advice from other Eleven owners and fitted ducting and an oil cooler. 

Fan is still a pusher mounted to the Westfield bracket as I couldn’t see how I could fit a puller fan in the limited space behind the radiator. I’ll give this configuration a go and if I need to look at the puller fan at a later date. 

oil cooler is a Mocal kit for an MG Midget so the hoses aren’t a perfect fit but should be good enough to prove whether there’s a benefit in having one fitted.

Stoneleigh 2018

First weekend away with the Eleven with over 300 miles in hot weather over the two days.

Particularly hot on the way home and whilst nothing was terminal the temperatures were not stable at cruising speeds and the oil was getting too hot and impacting oil pressures at idle when stuck in traffic so I've decided to add some ducting to the radiator and an oil cooler.

I'm still trying to work out the best way to fit the oil cooler.

I took advantage of the good weather and fibre glassed/gel coated the bonnet where the holes were drilled for the headlight pods.

Visit to Slark Race Engineering

Today was the visit to Slark Race Engineering to tune the engine and confirm the tracking.
As with the IVA the weather was truly awful so a good test of the tonneau which turned out to provide reasonable protection.
Neil confirmed the static timing and set about establishing some baseline runs and playing with the advance map.
When he was happy with the timing he then started playing with the mixture and determined that it needed more fuel mid-throttle but was slightly rich on full-throttle.
He removed the needle and trimmed the mid-range section and after a couple of goes was happy.  After a bit more adjustment the engine was putting out 84bhp with 80-90 lbs/ft of torque between 2.5k and 5.5k.  The more observant will notice that I've fitted the 1" extension to the rear shock absorbers, cut a hole in the ali panel to allow the diff to drop further and halved the lower trailing arm bolt heads to allow them to pass the chassis - the car seemed much better for it but it's early days and I still need to play with the shock absorber settings.
Next we setup the ride height, camber and toe-in all of which only needed a small amount of adjustment and finally we put the car on the scales to find out the overall weight.
Including 3/4 tank of fuel.
The weather on the drive home was no better than the journey there however, the engine was running very well and the car was noticeably more torquey and smooth.

I went to Gurston Down to watch the racing which included the Westfield Speed Series , when I got home the V5C had arrived for the Eleven so I focused the rest of the day getting it ready for blatting on Sunday.

Once the car was ready Myles and I completed a circuit around Yeovil covering 12 or so miles followed by a bit of tweaking.  This was followed by a 65+ mile run to Chesil Beach and Lyme Bay with Tricia, the car ran well throughout but the suspension needs adjusting especially the rear.

Waiting for the DVLA

I've posted off the registration paperwork to the DVLA and await their response - hopefully an age related registration based on the donor MG Midget.

In the mean time I've started to work on the transformation of the Eleven

New motorcycle combined brake/rear/number plate light, reverse light and fog lights plus smaller retro-reflectors and number plate (assuming that they allow me to use my retention plate - and we all know what assume means!)

I've also had extra bolts welded to the driver's seat runner so next weekend will be focused on the cockpit.

IVA - Passed

After a couple of frantic weeks juggling work and garage time I eventually finished the car ready for it IVA on the 14 Mar.

Head light pods

Number plate bracket and fog/reverse lights
Adge agreed to follow me to Exeter with spares and tools and we headed off at 06:15 for an 08:00 start.

The first impression was how nice the engine/exhaust sounds, second was how bouncy the ride was - the Protechs need turning down a few notches. Finally the speedo stopped working anything over 40 mph so no opportunity to confirm calibration on the drive there as I'd planned.  We arrived with 1/2 hour to spare so I quickly adjusted the gap on the speedo sensor, topped up the fuel and then took the car for a spin around the car park to confirm that the speedo was working.

Outside the test centre - starting to rain
 After introductions the examiner asked me to drive the car into the rear of the test workshop.  The first steps were to conform chassis/engine numbers, test all the lights/horn and internal/external projects.  Overall the examiner seemed happy enough but didn't like the routing of the harnesses through the rear bulkhead.

Next the car was put on a hoist and given a good look over underneath including confirming lock-to-lock steering nothing was catching/touching anywhere - it wasn't and the examiner suggested that the steering limiters could be reduced as there was plenty of clearance.

The car was lower and then driven through to the speedo test - worked all the way up to the test limit of 70 mph but swapped from over reading to under reading very unusual and a fail.

After the speedo the headlight dipped beam was tested, the pattern was okay but the aim slightly so we were allowed to adjust.  Then the emissions test followed by the noise test where the car was reversed out of the workshop, the test was conducted at 3/4 of 5,000 rpm at passed at 97dB whilst outside and the rain was holding off the car was driven to the mirrors test area where all passed, then back onto the workshop for the brake test.

The initial brake test was the standard MOT then followed by a more complex multi-point test to determine overall performance taking into account the cars weight.  Once the car had been weighed (595 kgs including me and a full tank of petrol) the readings were punched into a computer and - a pass.  However, the hand brake was assessed as having no reserve possibly a bit of stretch on a new cable being used seriously for the first time, again I was given time to adjust this to pass.

By this time it was lunch time and the examiner suggested I use the hour to investigate the speedo mis-reading and re-route the harnesses.  He'd agreed that the inner harnesses were okay therefore only the outer ones needed sorting and that the best way forward would be to re-route them between the clam bodywork and the rear bulkhead.  I started with the speedo and determined that the most likely cause was the alignment between the sensor and prop-shaft nuts.  I removed the sensor bracket and Adge drilled the mounting holes and made them slots so they could be adjusted.  I added an extra nut to each of the prop-shaft bolts, the whole thing was then reassembled and adjusted to read off the centre of the additional nuts and tested using the LED on the back of the sensor (accepting that this was not the best of indicators).  Once we'd finished the examiner put the car back on the speedo tester and it read a consistent under measurement across the whole range, so progress.  After a couple of attempts it was over-reading within the IVA requirement so only the harnesses left.

The examiner looked at the re-routed harnesses and, whilst an improvement, thought that it had transferred the problem to the clam rather than the bulkhead.  After some measurement and discussion we agreed that the bodywork would need to be trimmed to allow the harness a straight run from the chassis mount to the rear of the seat.  While the examiner finished his lunch Adge and I drilled and filed the relief slots and while not pretty they did the trick.  The examiner confirmed he was happy and even said I didn't need to re-trim with rubber as the bodywork was nicely bevelled, the rear of the seats is excluded from the interior projections test and the transition from interior to exterior projections is 25mm from the edge of the body - result.

Passenger side - not too bad

Driver's side - not too good!
While the examiner went to his office to write up the certificate, Adge and I packed everything and taped a temporary cover over the passenger side of the cockpit as it was now raining heavily.

The drive home was wet and not the most enjoyable but at least the IVA was passed.

Clam edge slots blended across the whole of the cockpit opening and covered

Why Do Today What You Can Put Off Until Tomorrow?

Last weekend I decided I'd done enough and sorting out the reverse switch could wait for a week:

 Well this is a week later! and it's getting worse
