More than 12 months after IVA I’ve now finally sorted out the problem that was giving me Engine hesitation in 1st and 2nd gears on my LS6.
When I wired up the Engine loom I’d wired the clutch pedal position to positive in order to get the engine to start. I’d read on the internet that it was required because US cars don’t start unless you are depressing the clutch.
As it turns out you don’t actually need this connected at all. Car started fine without the CPP connected at all and now does note hesitate at all.
Massive extra power now in all gears. Scarily quick. Hypothesis is that this was either affecting the spark tables or affecting something else in the PCM. Either way – Just glad to get it sorted. Many thanks for all the help in sorting this (especially Paul Spinks, Jim Thompson, , Martin at Marlin Cars, Meena and Andy).
After the emergency change to the rear shock we are up and running and completed the London to Brighton kit car run. Weather was brilliant and it was really good to meet up with the other GD owners. You can see here the video after the stop where we followed Paul and Corine into Brighton. Thanks for leading the way guys!
Having missed out last year due to lack of water proofing this year is looking far better on the weather front.
Car is now well polished and we have also fitted some Spats (Inspired by Stonleigh). They are actually glassfibre that has been wrapped in shiny vinyl car wrap to resemble chrome. We’ll see how long they last on the upcoming trip to Spain.
We’ve now started to try and sort out the car ready for the next year. Key topics are:
Front Suspension – There is definitely some movement up front. You can occasionally hear a knocking sound that is worrying and the suspension creaks when under compression. It would now appear that the front suspension has a small amount of forward and rear travel and that is what is causing the problem with the knocking. Problem is that getting the pins out to remove the wishbones is not at all easy now. A jag specialist had the car in for 2 days and couldn’t work out how to do it (not sure why – especially as looking at it cost a fortune!). The creaking appears to be coming from the top wishbone due to wrong greasing. CFS motors really didn’t do a good job with the reconditioning here.
Rear differential – Main problem here is that CFS Motors didn’t build the diff properly when reconditioning. Oil leak from the left hand side has left oil on the discs that causes a bit of a noise when you are on the brakes (annoying and something that needs fixing). All of the other joints on the rear have small movement which is just indicative of a really poor job. 2 garages have told me that the work is below standard and should be redone.
The other issue is with a leaky damper on the right side. In order to continue using the car I’ve had to order a new unit from GD and then swap it over. Top marks for getting that to me quickly. Fitting it was a bit of a hassle as you also need to loosen the roll bar in order to be able to get the fixing pin back in. Took a lot longer than planned
Engine – Still Hesitating on WOT. We have now rewired the fuel pump, changed fuel pipe, changed fuel regulator, run a high capacity electric line and relay and confirmed that the fuel at the rail is now a solid 58psi. Voltage at the pump is now around 13volts which is good.
Injectors have also been changed but with no luck. Still trying to change out things to solve the problem. Here is the trace of the problem (Thanks to Paul from Wortec).
Next plan is to change the line to the main fuse board so that it gets a clean full voltage feed from the battery.
Niggles – Fixed the problems with the fog lamp not illuminating and the wipers not parking. Turned out to be a loose connection on the link between the dash wiring and the main bundle. Only the 2nd heater setting to fix now.
Having now completed 1400 miles of motoring around UK to shakedown the car it was time for the big trip. Our goal was to travel around the North of Spain with our friends and then blast down to Portugal.
DAY 1 – Ferry.
Waiting for the Ferry
Surprising how much you can get into the boot of a Cobra
DAY 2 – Picos de Europa
Cobra survived the trip on the boat
The rather steep drive to our Chalet!
Relaxing after a day in the sun
Luckily Cobie doesn’t have carburettors but the MG does!
DAY 3 – San Gloria pass to Ribadeo
Top of the San Gloria Pass
Proof that we got there
A nice view from the top – Once we managed to navigate the dirt track
Cobra at the top
Some nice twisty roads
DAY 4 – Ribadeo
We managed to get Cobie a garage for the night at the Parador
Parking at the beach!
Jane exploring Cathedral rock
Where has the sun gone?
DAY 5 – Somiedo
Cobra on top of the Mountain
A little bit of rain overnight
This is a nice town the mountains
Yes – The roads really were that steep
Sun’s back out!
DAY 6 – Someido
A view from the top
Taking over the car park
More pictures at the top
Another height marker
Hmmn – A very expensive clothes horse
DAY 7 – Cavadonga
A bit misty in the morning.
Another shot of the cars
Cobra and MG at the top
There are a lot of these about – Some on the roads
DAY 8 – The drive to Zamora – Our friends have headed back and Cobie is on here own,
Lots of flies in Spain – Less than there were though!
Every trip in the Picos goes through Riano
Over the pass again – Not doing fuel economy any good
DAY 9 – Zamora – A day off after a week of driving!
Relaxing on the battlements
In front of the church at the top
Day 10 – Driving to Portugal (Through a storm)
This rain was really heavy!
Duct tape has come in handy!
You can see the water now inside the car – Hood bow broke when I was fitting – Not a good timing
Luckily rain didn’t last that long
We made it!
DAY 11 – Duero Valley
Our Portugese Parador – Once the storm had passed
Hmnn. – Rain got into cobie in the night. More Duct tape required
Good idea to fit poppers so that we can easily take the carpet out
Some nice twisty roads into the valley
Vineyards – lots of these
Vineyards – lots of these
And this is where the expensive stuff is made
Lots of street cobbled streets – We must have done up all of the bolts!
DAY 12 – Lago de Sanabria
You can spot nice little places like this all over Spain and Portugal
Nice little stop
In front of the mountains
This is straight but incredibly bumpy
Back into Spain
Hmnn- Steering connector appears to have come a little loose – Not good!
DAY 13 – Astorga
Hmn. We’ve found a bolt that obviously wasn’t done up tight enough.
DAY 14 – Heading back to Potes
We’ve been here before! Third time at the Riano petrol station!
This was not uncommon
San Gloria again
Top of the world
Familiar! – Easy on the way down
Nice day for a long drive

A nice (long) walk today
That was a long walk
In front of the accomodation
DAY 16 – The trip back home
Escorted by some classic bikes.
Between Cobie and the bikes we woke everyone up!
Back at the terminal
Here it comes to get us
Hit the sump getting on – But we’re ok.
Day 17 – Back home
On the motorway – Left side of the road!
So another 1400 miles (Cobie has done more miles abroad that in the uk). Everything appears to have held together. A little snagging list now to sort out but generally everything worked OK!
After more than 1000 hours and 4 years we have achieved our objective – Goodwood 2015!
Cobra was waved through into the classics area no problem at all. Quite a few people had a good nose around including a French guy who seemed to be quite interested in the wheels. Unfortunately he didn’t speak English so we couldn’t work out what he wanted to know.
In the last few weeks we’ve (mostly Jane) has spent a lot of time on the outfits and I think they turned out well too!! Quite a few people liked Jane’s dress. The finishing flag style went down well.
Time has come to tidy up the boot and get it ready for the trip to Spain in a few weeks time. We decided to box in the tank and the pump assembly to give us some sound insulation and prevent anything from damaging either item. First order of business was to mark out a pattern of the boot shape using paper .
We then transferred this to the wood and cut it out (The wood was actually the last remaining part of the crate that the engine was delivered in – more recycling). This car is very environmentally friendly!
And now fitting the boards into the boot.
In case we need to replace or remove the differential at any point we’ve made the top section in three segments. This will enable us to remove the centre section fairly easily and get to the bolts securing the diff. Useful for when I upgrade to a Quaife!
We then had the problem of how to deal with the area behind the roll bars – definitely didn’t want to take those out to fit the boot. What we did was make up some sheet aluminium and use this to fit behind the bars so that the carpet has some support.
And the finished article
And then it was just down to boxing in the fuel pump
Now only the carpet to go and after a slow start I was amazed when the majority came together in a single day. Lot of measuring to start with…..
Using tape to protect the carpet from the glue. We again didn’t remove the roll hoops to fit the carpet. Instead we cut some neat slots to fit the roll bar. Using pins to identify the location of the holes, we cut around 40mm and 30mm holesaw attachments with scissors. If you zoom in on the photo below you can just about see the pins. These were pushed through from the top of the carpet when it was trial fitted.
And here is the final boot trimmed. Overall really pleased with the finish that we’ve managed to achieve.
