I fabricated a simple removable block off plate for the oil cooler to minimize its effect in road driving. It seems to help, but it's still quite slow to warm up compared to my Westfield. That car has a 230hp Duratec with Raceline wet sump, no oil cooler, and a much smaller radiator. It's never had issues with high oil temps on the road, even in very hot weather, and operating oil temperature is also reached much more quickly. Factor in the Caterham's dry sump with extra oil capacity and the oil cooler, it seems overkill for the road. The Laminova-style oil cooler, as mentioned in many threads on this subject, seems the best solution for road use.

Really nice work! Someone needs to sell that throttle cable adapter. I tried to radius the edges of the factory opening to reduce the likelihood of snapping a cable, but this is a far better solution.

I had to place the throttle cable in a large figure 8 to run the linkage in the back but it's worked well thus far. The lack of space in that area was certainly challenging, and it's even more so with your closer-to-stock setup. Looking forward to seeing your final solution.

I had trouble with the upper hose as well. My set up is a little different than yours as I'm not using the submarine mount for the water temp sensor, the throttle linkage is on #3&4, and I'm using a different belt tensioner setup, but it might give you some alternate ideas. The key for me was using a convoluted hose and printing a bracket to hold it in position. Pictures and a few details are in this post: https://usa7s.net/ips/topic/13992-520r-sv-build-has-commenced/?do=findComment&comment=134367

A similar question was asked and answered here on USA7s about the tachometer. Based on the photos, it looks like the connector is the same. Provided someone can confirm they are, you'll have your answer. -John

An Admin can configure which editing functions show based on device size. The default limits the options for small screens (i.e. mobile) given the limited space, but you can control which show. You can also change carriage return behavior so that there is no extraneous line inserted. Drop me a PM if you want me to walk you through the necessary steps in the admin console for either change. -John

I did a little more digging and this is an iPhone setting that will transfer a photo in a compatible format when emailing or texting, which is another way of saying it will convert HEIC files to JPEGs given the former is not universally supported. To enable this, go to Settings, then Photos, then at the bottom of the screen, set "Transfer to Mac or PC" to Automatic.

Interested to hear what you find. My sample size is small, so my experience is certainly not definitive.

I'm not a Mac user, but a simple online search revealed the following. Might try that and report back to the group. In my testing, the HEIC issue is not present when using an iPhone. Just as they automatically change an HEIC file to a JPEG when emailing the image, they also upload them to the forum as a JPEG with no other changes. I'm not sure if I've simply been lucky or if that is consistent across Apple's mobile devices. I will say that in every instance where I've seen an HEIC file uploaded, logs show the device used was a Mac, not an iPhone. You can convert HEIC images to JPEG format on a Mac using the built-in Preview app. Here are the steps: Open the HEIC image in Preview. From the top menu, select File and then Export. In the Export dialog box, select JPEG from the Format dropdown menu. Choose a location to save the new file and click Save.

And since we know it's the title, if you further filter to search titles only, it is the only result returned.

No, I simply pasted the phrase with no quotes into the search bar, set it to Everywhere, then once I had the initial results, clicked on the phrase filter beneath. I just tried it again and had slightly updated results:

When searching for "Banner Battery model is 053 034", then clicking on "The phrase "Banner Battery model is 053 034"" located under the search box, since I know I'm searching for a specific phrase, I get the following. Three results with the most recent on top. Pretty good. The key is to use those additional filters based on your search terms. Are your search terms a specific phrase with the terms in that specific order? Do the results need to include all the terms in any order? Or are you just looking for as many of those words as possible? Invision also provides other search filters when you click on "+ More search options" that further help you clarify what you are looking for.

dropbox links to a page where the image is displayed, not the actual image. Invision needs the image link. As a workaround, I clicked on your first link, then right clicked on the image and selected open image in new tab. I then copied the URL of the actual image from the new tab, then pasted in in the editing box and also tried it via the Other Media option. Worked fine both times.

Yes, mine 😮 I've been too lazy to deal with it, and yes, you should be suspicious of me. BTW image URL insertion via the Other Media option works fine for me.

This may not be the issue, but I'll mention it since others may run into it. Invision requires links from secure sites. If you attempt to use a link with http rather than https, it will fail without giving a specific error.

Windows 11 Dell Laptop and Dell monitor. I tried both Edge and Firefox. I also tried an iPad and had the same results. Screenshot from the laptop below. The top item has been read and the second item has not. I can empathize with the to-do list. I moved a forum to Invision a few years ago.

On my device, they are effectively identical. But I'm sure there are a lot of other things on your plate that are a much higher priority, and this would get bundled in with any other theme changes you want to make based on user feedback over the next few weeks.

The unread dot before a thread title in Activity Streams is showing correctly, however, read content continues to show in bold text there and within the Forum view. Default behavior for Invision is to unbold read content, making it easier to spot unread posts, so I'm not sure if this is a bug or an intentional choice.

Click on your username in the upper right-hand corner, then Account Settings, then Content View Behavior on left side of Settings page, then select Take me to the beginning.

I just completed a 420R SV build but swapped the standard engine for a 2.4L Duratec with Jenveys. Although you didn't ask about fitment, I discovered the hard way that it does require some other changes to bolt on to the current models. I'll share those in case that is news to you too. None of these are difficult but they do require other parts. The factory belt tensioner fouls the Jenvey's throttle shaft, and of course the TPS if you mount it to that side rather than the firewall end. The fix is to use the manual tensioner available from Raceline, and possibly others, which in turn requires a shorter belt. The Jenvey throttle linkage fouls the upper radiator hose. I had to fabricate a new hose run to work around this and ensure the two would never touch. There may be other throttle linkages available that won't have this issue but I already had the Jenvey linkage so didn't pursue other options. Hopefully others can chime in to answer the questions you actually asked :) -John

The spacer should work. If it's helpful, here are Ammo's instructions for setting the chain tension correctly which will determine the length of your spacer: "Attached is a drawing that explains how to tension the chain. You basically fit it without the spring and plunger first and adjust the screw until the chain has 10mm movement between the sprockets. It must not be slack anywhere else. I press down hard with the heel of my hand on the chain between the sprockets so all, the slack is there. When the engine heats up you end up with 3mm movement which is about right." Also, if interested, this post shows side-by-side photos of the stock and mechanical adjusters as well as other related information shared with me by Ammo, Raceline, and Esslinger:

Regarding the mechanical tensioner, be aware of a warning Ammo Castellani, who started Raceco, shared with me several years ago. New Duratec timing chains stretch. Therefore, if one is used, a mechanical tensioner will require a re-tension which requires removing the engine cover -- i.e. major job. For this reason, he always installed a used chain when swapping to the mechanical setup. Obviously this won't matter if you are keeping your current chain, but wanted to share the info just in case you end up with a new chain. -John

Thanks James, very helpful! I've taken measurements at a few points that are pretty close to the Bosch curve. I'll use that and monitor as you suggest.

Is anyone using an AiM display that has been configured for the factory temperature sensors used for the coolant gauge and oil temperature? (parts store link here) Apparently it's a very common sensor used by a number of different car manufacturers and made by several sensor companies under the part number MD091056, but no one seems to publish any of the data. I've already checked with both US and UK AiM support, and a few Caterham specialists, without success. When testing the resistance output at a few temperatures between freezing and boiling, it became clear this is not a linear output, so having the actual resistance curve is needed to ensure any accuracy for my oil temp readings. Thanks, John

The fuse box is the factory version that normally sits sideways under the scuttle, but is rotated 90 degrees, then inserted into a 3D printed case that protrudes into the engine bay. Here are another couple of photos, but I don't want to derail this thread.
