Andy, Talking to the Rookapaedia 1, he understands that Essex's and Colognes both have an issue with hotspots in the block, so a high pressure cap is needed to keep them from boiling even at low engine temps. He was saying that if left unchecked it gradually forces coolant out until the level gets low and it properly overheats. Doesn't sound like your problem, but worth checking. Oh and you're welcome, nice little diversion. Not quite up to Johnny Bravo standards, but should do the job . Nathan [1] A source of much arcane knowledge who both Andy and I know Already running a bit higher pressure cap (15 vs 13 psi I think), I've also added a couple of extra flow paths to the heads where they're known to hot spot and locally deform/crack the heads (between exhaust valves) so that should be helping a bit as well. Think it really does come down to a lack of airflow across the rad, but hopefully will get it all together soon and see how it copes.

After working for several years as a vehicle cooling engineer, if I was you I would hold fire on the electric w/p. In the world of engine cooling, air flow is king. If your revving the engine inside normal limits there shouldn't usually be any pumping issues. If your over revving I'd change the pulley size and slow it down. The company I used to work for did a lot of development on electric w/p and they're controllers and concluded they were handy for rapid warm up and emissions and little else. Not sure how the set up is in your engine but make sure removing the standard pump does not make a high pressure area into a low pressure area so coolant flow is affected. Before you do anything get your tune right as this is probably the issue. Whilst developing a cooling system on a production car we struggled to keep it cool for over a year doing wind tunnel tests. One day the guy on the tuning side of the manufacturer said they had finally got the engine tune right and it instantly knocked 10degC off the top hose temp. I also wouldn't worry about how high the temp is getting on the dyno as it's obviously gong to run hotter than in real life Hope I don't sound like I'm preaching Thanks for the great response, not preaching at all, and all good points and worth raising as easy to overlook the basics . I'm fairly sure a better fan would greatly improve the issues and may even fix it, but the pump nose simply meant that a good setup couldn't be achieved without chopping the body work around a fair bit. So the electric pump is a kind of two birds one stone decision, plus very handy on a Hillclimb a car that sits idling, does a sustained very high load Accel then stops dead at the top of the hill. I would tend to agree with the Dyno issue except I can get it to run too warm and struggle to cool quickly enough with a few revs, zero load and not very high ambients, so clearly there's something not working very well and I know quite a few people struggle getting high reving/power colognes to cool effectively. Have tried a couple of pulley sizes and sadly slowing it down didn't help much at all. As for the tune, well it's fueling just a bit rich (tends to help them run cooler) and whilst the timing was out it was such that over heat shouldn't be an issue. Oh and may have already cut metal on the pump

Another long gap between updates, but I've got a fair excuse this time having the joy to report becoming a father for the first time at the end of March I'm now learning how to build cars in the hours between 5 and 8am - so progress is happening, if a little slow, especially since my mind doesn't work as well before 8am meaning things seem to take longer than ever! Sleep deprivation doesn't help either! Anyway the 4 poster is now fully up and running and the Capri has finally made it to the rolling road to bed the engine in and see how things are - The good news is we didn't kill it! The bad news is a couple of issues were highlighted - Problem 1) Cooling - we just couldn't get the damn thing to cool fast enough, despite me removing stats and removing the warm-up by-pass. In the end I've concluded the stock pump isn't flowing enough, and the fan I had (push due to package space) was useless. To that end I've got a brand new electric pump and because this allows me to taker the nose off the pump I also have space to fit a proper high power suck fan. I've gone for the top end 150 ltr/min EWP150 pump from Davis Craig with full digital control Interestingly at 3000rpm we found I lost over 10 BHP with the temp at 95degC verses 80degC. Hence going for the highest flow and full digi control, the plan is to try and get it to hold the temp between 75 and 80, rather than the normal 90odd. Problem 2) Timing - once we'd bedded it in a bit and moved onto power runs we initially got quite excited, >100 BHP at 3000rpm, but instead or really ramping up from this point it tailed off and flatlined at 4000rpm makign only 150bhp at the flywheel. Now this isn't bad, afterall a 2.8i only makes 160, but peak power should be at >6000rpm, not 4000! Clearly something was amiss, with cam timing suspected. After getting home I did a timing check by valve lift rather than with the timing angle wheel and found we only had 2.9mm inlet lift @tdc, rather than 3.5mm as it should be. Stepping one tooth took it too far (4.12mm lift) so it became clear why I'd timed it like I had - best you could with a fixed gear, about 3deg late basically. The solution - get the file out and make a new keyway - got this done this morning and we've now got correct timing. A fully adjustable gear would be the best solution, but this can wait till I'm trying to get the last bit of power from it. Problem 3) Airflow - so the other reason it might flat line at 4000rpm was that the airflow started to stall - maybe it couldn't draw any more air/fuel in. Given the timing was out the airflow probably wasn't too big an issue, but I'd only got an IDF 40 (with 32mm chock) to fit with the intake and adaptors I was using. A 40IDF is normally limited me to a 34mm choke (you can overbore to 36mm but there's a rise of not getting the flow speed needed over the carb). Anyway, after a few hours with the die grinder and a file I've got the intake opened up to take a 44mm IDF - so can now run a 36 or 38mm choke - hey presto more airflow. I only had 44's that needed complete rebuilds and since time is an issue at the moment I've splashed out on a new carb - like so All I need to do now it bolt on the intake and figure out the pump location and fit it all - simple, I hope. First round is end of July, but been invited to go on a stand at Classic Ford (early June) so to say time is running out would be an understatement - I do love a deadline!

Never been a fan of the Spiders, especially the later ones, but this looks great, something of the Mazda Cosmo Sport about it, and it really really works. Thanks for the share

Now that looks awesome! Nothing better than twin carbs on mass. Sure you know this but those seive filters aren't great for flow, but they do the job for getting things running

Taken sometime Tuesday night it appears. Done by someone who knew what they were doing as got through the 2 hitch locks on it, and broke into my unit which took some force to do (sheared hardened steel dead bolts). It is a Brian James Clubman SN SJBTCTGBP2W010640, was waring reg M375 NMO, but they'll have ripped this off I'm sure - looks like this

Not a car update, but an excited one as I finally got something I've been waiting a long time for, a ramp in the workshop And not just any 4 post, an alignment one that'll go with the Hunter alignment gear I picked up cheap a couple of years back. So very stoked at the moment - can't wait to get the motor powered up (need an inverter) and get playing with the Capri suspension geometry. The best bit though, getting a bunch of mates together, firing up the BBQ and cracking a few beers - Only issue is that the ramp is rather big, very big... so the Scimitar (which was always a daft idea!) probably has to go, ah well rather have the ramp anyway

Hi all Will be going from Warwick to Dereham (Norfolk) on morning of 16th Feb with an empty car transporter trailer. If anyone needs a car taking in that direction that's close to my route (probably A14 to A508 then A47) then drop me a PM and will see what I can do. Smallish cars only I'm afraid (uptown 1200kg). And runners/rollers only please

Thought he would give it a single headlight treatment like Capri...wagon.😊 I may have some lights that I'm considering, but single rounds would be far too obvious

Body drop it then do a Liberty-Walk makeover Kind of worried how well I think that would work! Certainly be different!

Proof that it's alive again! Seems to be running better than the last build. Repaired with a new piston and a liner in the block. Have also adjusted the cooling circuit so we'll see if that helps, temp certainly seems more stable now. So just need to get it rolling roaded and it's ready for this season

Cheers guys, some good feedback. Still not fully thought through the galvanising, but will almost certainly get it blasted as have a place that does stuff so cheap it'd almost cost more in wire wheels for the angle grinder (plus it's so nice just to hand something over and get it back all clean just needing some paint). Caliper wise, thinking Princess because I have them lying around plus they always have really nice pedal feel and worked great for 8 years on my old Escort track car. But the sliding 5 series bits I will keep in mind as a back up as they might help with other clearance things In other news I got up to 6 bolts/hour yesterday, just the rear bumper beam area to take to bit now. Also examined the Pinin axle, and let's just say it's not what I was told it was (i.e. it's an open diff...) You win some you lose some - might just use the stock axle now and invent a disc brake setup. Will help the budget, plus the only wheels I can find I like in 5x114.3 are way too expensive for this built. Anyone else struggle with flux in projects? I just can't seem to get a fix on exactly what I'm going to do with this one yet...

What is it with rusty bolts?
When you really really don't when them to shear, because you'll have to drill things out like say an exhaust stud, then they'll shear with glee.
But when you've really rather like them to just snap so you can pop the bits out, the damn things laugh at you and the heads round off instead, especially if there is no easy access to get a grinder/saw in to remove said rounded head. Grrrr....
So currently I'm managing an average body fixing removal rate of about 4/hour - this is very sloooow
On the up side, while many of the bolts look like they've been in the sea for a few years, much of the chassis continues to be surprisingly good - even the roll hoop brackets are basically solid.
I was just going to raise the body a bit, repair the outer rails and front riggers and bodge some paint about, but given how much I plan to remove from the chassis eventually, I'm now thinking about pulling the chassis out fully, getting it blasted and maybe galvanized - that way the running gear could be good for a damn long time.

Cheers guys, fingers crossed it'll be worth keeping an eye on Not a lot of progress on the car itself, save for emptying it out (there are a few useful bits which is nice) and getting it in the air. The most amazing find is that it only seems to need the side riggers replacing... which I'm finding way too hard to believe. Have got some from QRG since they're only £20 odd quid each galvanised and plan to jack the body up to fit - sure that'll be fun. Apparently can be done without this, but want to get the body up just to check over the rest of the chassis (there's no way it can be this solid, surely?!) Also picked up some way too cheap wheels/tyres to make it mobile - one set of MGB rims with good tyres for £30 - pretty happy with those as half a chance I can sell them for more when I'm finished with them In other news, a plan for what I'm going to do is forming. I'd like to do a fair amount of things, but obviously need to keep it in the 8 point rule, so going to use the original gearbox to retain the points and modify the engine, suspension and axles. How? Well brakes wise I want to go the vented at the front, and change to discs at the rear. I've got a pair of Austin Princess calipers stashed away from years ago (a £5 bargain 15 years ago) that'll I'll rebuild and use for the front, and combine with some vented discs, possibly from a Toyota Cressida. For the rear, well you can get some brackets from Retro Power, for about £50, or you could go a little further... As mentioned, the Scimitar is a bit long legged, so a shorter diff ratio would help, the axle weighes a ton so a lighter one wouldn't go amiss, and who would say no to a cheap LSD (or a Torsion one anyway)? I give you The rear axle from a Mitsubishi Pinin 2.0 GDI Sport - Torsion LSD, disc brakes lighter than the old 4HA and a 4.363 ratio (maybe a little short...) and almost the same width as the Scimitar axle. Left field I grant you, but at £100 for the lot, I dare you to find a cheaper way of getting all these things. The PCD is also 5 x 114.3 (so 5 stud version of the std Scimitar PCD) so the front hubs can be easily modified to match and this also means a very wide range of J and Ford US spec wheels will fit - NASCAR spec steelies anyone? It obviously needs a damn good service, but parts are nice and cheap (£20 for a pair of discs for example). First step will be to cut off all the brackets and make it a plain axle and then put on the mounts to link it up to the car - simples.... Suspension wise it'll be nothing crazy, a set of coilovers new bushes and probably changing to spherical joints on the axle end of all the rear end links. Costs to Date: - Car - £260 - Pinin Axle - £100 - Pinin Prop - £20 - Wheels - £30 (to be sold on later) - Side Riggers - £40 - Front Calipers - £5 RUNNING TOTAL - £455

Today's update, isn't that interesting but I some how tool me over 2 hours to get the car off the damn trailer - never known tyres so bad, couldn't get any air in them at all. In the end dragged it of and got it on some trollies. In its new home. Was so knackered by the time I got it in I didn't manage to have too much of a look around, but on the surface of it the chassis is way better than it should be for £260 - will see soon enough if that's really the case!

I've always liked these things. A zetec sat far back in the engine bay should make it a pretty good sleeper. whats the plan for the bodywork? Not totally sure what the plan is, but got a few ideas revolving around the original Ogle Scimitar GTE So something involving some glass in the roof (done in a way that doesn't need a one off piece as above) and maybe something around the headlights, not quad, but something else.
