Some more progress but as always modifying stuff is never straight forward, the modified driveshafts allow the wishbones to droop further than before so the springs become loose so now need to fit some check straps. Work continues on optimising the length of the driveshafts.

Was looking for a dimmer switch as the instrument lights reflect off the screen at night so took a chance on a Jaguar switch but requires addition components probably a resistor or two currently acts as an off/on switch which will have to do for now.

At Forrestburn last year a slightly concerning issue with the throttle showed up, when pressed down hard the pedal would slip over the edge of the stop and then hesitate before releasing so a redesign of the throttle stop was required.

Surprising amount of time spent setting it up to JUST achieve full opening of throttle bodies, the inner wheel arch hole is slotted which allows the adjustment.

Have you considered helper springs instead of straps ? My springs are quite loose and was considering using these to allow me to drop the front a little for the track

George

Helper springs would be fine for the front as readily available but the rear is an unusual diameter so would be much harder to source without getting them made which will be expensive compared to the check strap from a LandRover. £12 for enough to do multiple cars.

The function of the check strap is two fold, the first to stop the spring falling out, the second to limit the pull out of the inner spider from the transaxle. The second issue is only relevant because of the modified driveshafts so not relevant for everyone.

This modify stuff is hugely time consuming but finally feel I'm getting somewhere.
IMG_20180318_140430.jpg
Sorting Driveshaft length
Despite the Clan nor being the quietest car on the block the knock from the rear shocks was annoying, thinking it was the top mounts I removed them but all seemed well with the bushes etc however the bottom bolt was a loose fit. As I was also going to be using it for attaching a check strap it called for some modifying, I drilled out and then reamed the lower bush to take a driveshaft bolt with minimal clearance.
IMG_20180318_184804.jpg
Check strap and modified lower bush
Transaxle mounts from Mike Dent needed fitted but I was reluctant to remove the newly installed engine and box so a little creativity required, cut the crossmember which allowed the transaxle to be lowered and the top fitting to be tapped and the mountings installed.

John

Saved them as I told Colin he might be able to get something back from the mega bucks he is spending on the car so you need to speak to him.

Hope everything sorts itself out, I had noticed your progress reports were quiet lately, Take care of you and yours.

Should have been getting on with Colin's Imp but as this Sunday is the next PCT at Forrestburn and uncertain about a double entry committed to getting the Clan ready so after sending the special driveshafts off to be welded I refitted the regular ones, fitted the exhaust which required a little more than subtle modifying - tyre levering the heat shield off the bodywork with a tyre lever, filled the gearbox, reattached the gearchange coupling, found some wheels and tyres that meet the regs which required different spacers to clear the bodywork, played about with the breather system and noted more bits I need to finish.

Then when I ran out of excuses got round to firing up the engine, took the battery out of the Octavia to use as a jump battery, took the plugs out and turned it over until the oil pressure came up. Put the plugs back in its Dejavu time no green light on the ECU - no signal from the crankshaft sensor, when I pulled of the plug the wires came out of the multiplug at least the terminals are still attached to the wires. Reinserted after bending the retaining tabs and all good :D

Seems a bit reluctant to fire but its been a while, its been upside down when the sump was off but when it does it seems a bit flat and reekie but maybe just burning off a bit of oil. Bring it up to temp but no change and when I take the plugs out back soot, which brings all the issues rushing back when the car was put together - throttle position sensor calibration, cleaned up the plus and take the laptop and reset the TPS and hopefully that will sort it :roll:

Been a few days since I updated, resetting the TPS sorted all the issues so ran it up to temp and as the thermostat opened and the coolant circulates through the radiator the recently modified pipes under the dash starts dripping. Bother :evil: drained the system down and tried resoldering the join and then up to temp again, Bigger Bother still dripping. Make three attempt before unsoldering and redoing the joint, what's amazing is a found a joint I had missed and this was not leaking :roll: :roll:

Once checked it was time to get it back on the deck and finally got to see the ride height and sump clearance. :D :D :D :D :D 6 inches at the lowest point - job done, when I get the adjustable spring platform rear wishbones sorted I can go from 2.5 - 6 inch sump clearance which opens up the type of events I can do from Production Car Trials to track days.

IMG_20180320_184621.jpg
Been running around in it for the last few days and so happy I don't have to listen to the gearbox whining still not quiet but no longer painful.

The rear shock mod has worked as no more knocking, although there was now some from the front which turned out to be a couple of loose bolts :shock:

Came across a couple of issues that I had noted previously but had forgotten about, the LED warning lights are great but too bright at night so painted over them which allows them to be seen without dazzling you.

The gearlever/linkage in the green Clan was great it fell nicely to hand but when it was transferred to VAK I had to lengthen it as the hole for the lever was further forward which makes it a bit of a stretch for me when harness done up tight, it also a little awkward to use on the road as no free movement. Great for the track but no so nice for the road, so have started to rebuild a standard lever with the UJ'd coupling. Grabbed a new ball for the pivot and shaft from my spares and will hopefully get it done and fitted tomorrow.

Getting there.

Today should have been straight forward but it was not to be, the new ball for the gearlever seemed to be oversized from the get go. When the top was bolted down it was effectively jammed so had to start filing it, eventually got it to the point it had a nice feel to it but had lost several hours.

Next onto shortening the shaft which thankfully was without issue, gear change is now better for the road with the added bonus of transmitting less noise.
IMG_20180323_184508.jpg
Finished off the breather system - my thoughts being at high revs there is a lot of moving "air" in the engine and the little pipe on the filler neck is too small so builds up pressure in the crankcase - oil forced from dipstick - increasing the one on the neck to 19mm and adding another to the cam cover will allow a more air to escape and lower the pressure but don't want all the oil in the air to be lost so from the first catch tank it goes to a BMW oil separator with spins the mix and the oil gets thrown out and drains off and the gases vented to atmosphere. If it works there is the option of draining it back to the sump but will wait to see if it works first.
IMG_20180323_174350.jpg
IMG_20180323_174401.jpg
So far no more spillage from the dipstick although still looking for the best place to vent so it doesn't get drawn back in,

Different Mirror back in the original position at the foot of the screen but being better quality doesn't wobble . :D

Up early today and off to Toolstation to pick up a grease gun as couldn't find mine, can't believe you can buy an SIP air operated one for under £15, and got the kingpins greased before Dave Charles arrived and we headed to Forrestburn for the Production Car Trial.

Weather was great with the sun shining all day meaning the ground was fairly dry and firm. The Clan fair sailed up them recording all Zero's for the morning session beating the Imps/Clans nemesis, a Morgan V8 with LSD. In the afternoon Hill 2 was changed to make it more difficult and they certainly achieved that and I scored a 6 and a 7 but continued clearing the rest and came away with a win, that makes 3 wins from 3 events since the car was completed. Makes all the work worthwhile.

The long first - works close ratio gearset - is noticeable but offset by the added tractability of the full engine management which means it still crawls up the hills without stalling which it would have had it been on normal ignition. Its a very tractable engine despite the R21 but its like a switch as it hits 3000rpm and lights up the tyres.
Maybe need to look at setting the idle speed higher for the next one (September).

Ah, in there lies a tale.

Last month the Morgan was first, me second, Dave third.

This is only Dave's second PCT and on his own this time, last month when we double drove in his Imp one of the first things I told him about was at future events don't follow the tracks left from previous routes. First test for us, Hill 4, he follows the wrong route towards Gate 5 and by the time he realises he can't get back across for it and so has to stop reverse and then clears the rest but obviously give him a 6 because he stopped. Pretty angry at himself.

Hills 1 + 2 were dispatched reasonable well but on Hill 3 he follows last months route and totally misses out Gate 10 , at the finishes he asks was it a one, only to be told no it was a ten. He came off the hill fuming with himself, due to this he also didn't see the funny side when one of the marshals told him it was a 6 when in reality he scored a 1 thinking he had done something wrong again.

After lunch he settled down scoring zero's and ones apart from the tricky Hill 2. He had enjoyed himself and that the main thing, waiting on the results to see how we all did overall.

Well done Scott, sounds like you had a great day out in the clan which is progressing very well. I know just how Dave feels as I've done exactly the same following the old route in error. Never mind it's all a learning curve. Hope I can rejoin the fun in September.

More fettling today, the Clan only has a 3 gallon fuel tank and its not a simple task to change it because the injection pump lives inside so more to reduce the worry about running out of fuel I wanted to carry a spare fuel can. The regular rectangular ones won't fit the only space in the front compartment due the the shape of the bonnet duct for the radiator, I found a 5ltr fuel can that fits but had the remains of whatever concoction was in the Mustang's petrol tank and boy does it stink. Emptied the contents into the used oil drum and cleaned it out thoroughly and made up some mountings to hold it in place with a ratchet strap.
IMG_20180401_124953.jpg
Petrol Can in place
IMG_20180401_124943.jpg
Mounting brackets - still to be painted
Next up was wiring in the latest purchase - a rally intercom set. The Clan is now reasonably civilised but long high speed runs (above 50mph) will be tiring and with Imp Ecosse and Going Dutch coming up fast something that needed addressing.

As with most Imp engines the rear scroll drips a little oil, that I can live with that although Andy Jones is rebuilding a number of engines for me and they will all have proper seals. What I'm not happy about is the way its spun out by the flywheel and then spread under the engine in the draft when the car is driving, therefore made up a wee plate that will stop it being flung out into the airstream.

Plate to stop oil
Finally cleaned up the muck from the last Production Trial and refitted the Toyo Proxy's ready for next Sunday's trackday at Forresturn.

P.s. the place still stinks with the old fuel :evil:

Cheers Paul.

Sunday saw the Season Warm Up at Forrestburn Hillclimb, looked like it was going to be a nice day when we arrived as the sun was shining but clouded over and had a few light showers through the afternoon.

Clan ran well and the new gearbox with its long first a real improvement through the hairpins, standard first was too low now its a useful gear and with this engine no issues pulling away on the road :D

Wee while since I posted an update, currently waiting on TNT delivering my ECU back to me, had the Clan over in Holland for Going Dutch and had a great time. In addition to the organised runs we went to Gallery Aaldering, Louwman Car Museum and ER Classic Cars, the first and last of these places are car show rooms but nothing like I've come across in the UK having 250 -300 cars on display better than many car museums here and if you have the money you can take them home. The Louwman Museum was exceptional and recommend visiting if you get the chance, our time was slightly shortened because on the way there Alan Farquharson's Imp water pump pulley became loose and started wobbling and noisy, missing woodruf key and worn - fixed it with insulating tape on the spindle and send him back to the campsite where they fixed it properly. All in we did about 1000 miles and VAK never missed a beat whether pootering about at 20mph in the villages or at 80mph on the motorways in 30 degrees heat.

However, when we arrived back in Newcastle that all changed as it wouldn't start on the ferry :cry: the situation was not helped by the fact that the car was parked by a huge vent which as I went to start the car was switched on which meant the Clan was just about blown away and could not hear anything such as the fuel pump priming etc so we got pushed off :oops:

After a bit of poking about and not finding anything upon retrying it fired straight up, just then a female port official :roll: comes up and tells us we have to move - like we really want to be there. The upside is they want us off the site before we breakdown again so get sent to the front of the passport control. :P The 120 mile run home was without issue apart from the fanbelt shredding itself but as I had a spare a quick fix, my fanbelt tensioner idler is now in the bin, whether it was the idler itself or the fact the the bracket had broken I'm not sure but have found a belt that is nominally the same size but is a tighter fit that means I can achieve the tension I want without the idler. :D

It was obvious that with two of us going to Holland in the Clan with a roll cage and the spare wheel behind the seats luggage was going to be an issue so decided to build a boot rack, initially was going to make it from square tube and Colin suggested round, I went for oval.

Got the ECU back and VAK running again, when I got home from the ferry the clan started cutting out but turning the ignition off and on would sort it, well at least for a little while. Gets to the point where it turns over but refuses to fire and ECU shows signs of the processor not booting up so sent it back to Emerald who diagnosed a conflict due to interference and it had shut down.

I took the opportunity to have the unit upgraded to K3 which gives a lot more functionality particularly running 3 seperate maps and self learning via the lambda sensor. While it was away I decided to run new supply and earths, and a new TDC cable routing it well away from the plugs/HT leads and coil, fitted resistor plugs aswell as prep for the Lambda sensor.

Will have to see if this sorts the original problem, will use it for a couple of day before an Autotest at Errol on Sunday

I had interference /earth issues with the Canems ignition ECU on the Clan too. I rationalised the earths - making sure there was a direct 'ECU only' earth lead back to the battery for the ECU with no possibility of an 'earth loop'. Ie the ECU earth is NOT via the engine earth - or any other engine bay earth.

I still get radio interference generated by the original heater blower - the old school motor runs very 'dirty'. It interferes with a remote control switching unit I use for the fog lights (I know, don't ask) and it blocks the garage door remote when the heater is on. If I need to operate either remote then the heater blower needs to be switched off. I might delete the original heater blower and fit a modern 'inline' heater blower to the heater air inlet trunking at some point.

Anther source of trouble is the 'back emf' genereated by relays - make sure all relays have a diode over the switching terminals to prevent reverse emf generation.

After a couple of false starts the ECU is up and running again, the first issue was wiring the white ground wire sensor for the Lambda sensor to earth but i used one of the ignition spare wires also white and blew the fuse, easily sorted.

I had the car running in the drive but at 2500rpm the engine would miss and the rev drop then pick up again, the faults you would expect from a duff TDC sensor or reversed polarity - so much swapping of sensor and wires to no effect so I reverted to an earlier Map and the problem went away :twisted:

Test drive round the block making sure not too far from home and all seems well, Saturday took it a run to the shed and back again no issues so today took it for a play at Round 4 of the Scottish Road Car Series at Errol Airfield. I was No 1, well Car 1 that is, never had a clean run but good fun never the less, finished 8th overall.

Scott,

Looked like it was going well and you were having fun flicking it about at Errol. :D
Hear all about it on Wednesday.
Cheers

Latest trip out was Glamis Extravaganza car show last Sunday, great show and company as usual. Last year we hid under the event shelter as it chucked it down and was freezing cold, this year we hid under the event shelter to get some shade from the sun and heat :roll:

Good trade stands and bought some new welding clamps and door seals for the Clan along with another pair of padded boiler suits, last year I sat in them to keep warm.

On the way back got caught up in delays due to the main Dundee bypass being closed and had to watch the temp rise in the heat but max'd out at just over 90 degrees and dropped as soon as we started moving again.

Tonight brought the trailer home, which I had serviced last week and sorted some outstanding issues so it would be ready for the National. Need to take VAK to the shed and fit a new clutch, you can smell it burning when giving it some stick although its not slipping day to day. While I'm at it going to change the fluids and sort the leaking sump and try to sort the front arch clearance issues.

I'm hoping to get it remapped on a rolling road before the National and get a track day or two in while I'm down there.

Delayed start to VAK today, well most days are delayed starts but today more so as Amy calls me to say here exhaust has broken :(

Had her bring the car up, it had broken at the rear silencer flange, manage to get a new one at the same place I was picking up my new spraygun. Very expensive spraygun so no excuses now. Got her exhaust replaced after a fight with the bolts then got on with removing the Clan's engine and box.

It's a real faff with all the mods but once out I stripped the clutch and its just about down to the rivets on the cover side. As I can't see any other problems just wear, going to just replace the driven plate.

Sump "repaired" again - hopefully leak sorted this time.

Clutch plate replaced and engine and box back in place, depending on the time the gas engineer arrives tomorrow will determine if its Wednesday or Thursday that sees all the bits and bobs attached.

Next event is this Sunday's Coulter grass Autotest usually a great day out.

VAK all back together and some more wheel arch ground away to give clearance for the tyres so decided to take it home to check everything OK.

Had driven 1.4 miles - rally trip on - when the car smelt hot looked at the temp guage and its sitting at 105 degress - :shock: :shock: :shock:

Pulled over and checked the car over, water not circulating so tried reving it to clear any airlocks but no joy.

Locked the car and walked to the supermarket and bought a pack of water and topped it up after letting it cool at bit, this time got some air coming out the header tank, kept topping up as the thermostat opened and closed.

No more problems on the rest of the way home :D :D

The clutch felt nicer as well, the doughnuts are having an easier time with the double UJ'd driveshafts as no stress marks on them from flexing.

Lets see how it gets on at Sunday's Autotest.

Today's Autotest went without any problems apart from lack of driving ability - one day I'll realise sideways is not the quickest until then I'll just have fun 8)
