@Bartman did you pay with a credit card tied to your US address then provide a different billing address or did your brother order using his credit card? I have an order shipping from the UK in the next couple of months and was told they are happy to include items from other UK vendors in the shipment if it's helpful. I might want to take advantage of that, but not sure if the US card/UK address combination would fly with JWM given their liability concern. Thanks, John

That is a lot of kilometers! And based on the photo inset, it appears you are not the only one who enjoys going out in the Birkin

Actually they do. Look at the second photo for each option and it shows a diagram marking the length, height and angle, then those three measurements are included in the Details tab. -John

I like that idea. To me, the beach buggy vibe is predominantly driven by the fact the dash and body have no aesthetic distinction -- it looks like one giant piece of fiberglass. It's easy to experiment with contact paper to see the effect of different dash coverage to decide what you like best. -John

Done! We love long, drawn out build threads -John

Welcome! Sounds like a fun (and dusty) project. If you are planning to update this thread with your progress -- something I think we'd all like to see -- I can move this to the Build Threads forum. Cheers, John

Does Easimap allow you to see all the ECU settings or just a subset? If you have full read access it would be good to verify the tach output setting was configured correctly at the factory. -John

See the Lotus 7 section of the Downloads portion of the forum. You'll find one there as well as the S3 Supplement. https://usa7s.net/ips/files/category/5-lotus-seven/ -John

Wow, that's a find! Does the title show it's a CA car or from another state? If you post the VIN, some folks here can decode it and let you know a little more about what you bought. -John

I'm afraid I can't be too much help. That specific AP brake MC works very well in my setup, which has the same rear calipers you mention above, but the fronts are different and may not share the same piston size as the GT6 calipers. For reference, my front calipers are alloy 4-pots with 1.5" diameter pistons and were designed as a direct replacement for the M16 calipers. If you do opt for the AP, keep in mind this is not the standard Caterham MC, but rather the upgraded part that is included in the R-pack models and may be a little tough to find. As for a hydraulic clutch, my bellhousing was designed to work with a concentric slave cylinder. Someone here may have experience converting a Caterham from that era to hydraulic setup and can steer you towards a known solution. Best to start a new thread on that topic to ensure people see it. -John

Great, albeit sad, background story. Based on the evolution between the last two photos, this tribute to Lars looks like it's well on its way to a successful conclusion. I'm looking forward to following this journey. -John

Are you looking for a setup like the photo that also has provision for the fan switch or just that has the nipple? A quick search shows the one in the photo is from a 1.3i OHV Escort: https://www.ebay.com/itm/ESCORT-1-3i-THERMOSTAT-HOUSING-OHV-HCS-ENGINES-BRAND-NEW-1995-2001/251958942442 Although it's an Ebay listing so I should have prefaced that with "supposedly from..." If you just need a housing with the nipple, this one from Burton's could work if you don't mind drilling a hole in the boss for a brass nipple. https://www.burtonpower.com/thermostat-housing-with-boss-cast-alloy-x-flow-rwd-fp612.html -John

@KnifeySpoonyI sent you a PM yesterday morning a few minutes after your last post. Please let me know if it's still available. Thanks, John

Hudson seemed a little bored by your last kittens video. @Vovchandrhe does, however, enjoy most of the se7en videos you've been posting. -John

This explains the 16 cat videos that I've received from you since 6am yesterday. And yes I counted. And yes, counting that high was a challenge for me. -John

As someone who obsesses about trade-offs from various cam profile options, that's just not fair. I'm looking to forward to hearing the results from both changes. Thanks, John

Sounds like a nice little Christmas project! What power levels are you targetting with these mods? Thanks, John

Someone clearly doesn't have too many meetings today -John

Now that my order has reached the stage where it's locked with Caterham, I thought I'd post an update before the engine build thread begins (hopefully) later this month. The spec has evolved just a bit from my initial plan. Changes and decisions include: Heated carbon fiber seats. Yes, on the surface, heated seats may seem incongruous with a Caterham but they weigh a lot less than a heater and should take the edge off on Fall drives. Also, the heat helps my back should the Tillets prove less comfortable for me than the Westfield's MOGs. No Track suspension upgrade. A big concern for this car is the ability to put down power on less than ideal pavement; I don't want to get sideways on a narrow back road when passing a rolling pylon. After a lot of research, I've decided to go aftermarket with shocks and springs and have ordered a set of CORE dampers from Meteor Motorsport. The fronts have a digressive valve with linear springs while the rears are normally valved but with progressive springs. Simon believes this combination will give the best performance. Stock 3.92 rear diff rather than the longer 3.64. Bruce wasn't convinced Caterham would honor the diff swap request and given I'm unsure on the shape of the torque curve on the new engine, staying stock for now seemed like the better bet. If the traction control doesn’t work well, then swapping to the 3.64 may be on the winter upgrade list next year. Or I'll finally need to make progress on exhibiting self control (who am I kidding?) I've decided to stick with the Emerald K6+ native Traction Control rather than use the Race TCS system. Although I have more confidence in the latter working better, I might as well start with the no-cost option. Emerald is building the custom ECU loom now. Jenvey 50mm DTHTB vs the larger 52mm. Dyno tests from Raceline and Esslinger show the smaller set flow more than enough for my power targets and should have a slight edge on idle and low-mid range given the increased air velocity. As for velocity stacks, there are only two choices in this size: 40mm and 93mm. I'd prefer to use a cold air box and not cut the bonnet, so I'm starting with the shorter set but reserve the right to make dramatic changes here based on dyno results and how I feel about the torque curve after driving the car. Longer is definitely better for all but the top of the rev range, but I'm not yet sure I'll need improvements down low. I've opted for the Esslinger Stage 4 cams over the Raceline RDL 270. They should more than meet my power target and I do like they are an asymmetric setup vs the symmetric for the Racelines (interestingly, their more aggressive RDL 300 cams are asymmetrical.) The downside to this choice is COVID supply chain issues. When I placed the order in mid-July I was told they were out-of-stock and would take 4-5 weeks to ship. Five months later and I still don't have an ETA on when Esslinger's cam grinder will have the blanks for my set. It's beyond frustrating. Parts continue to arrive and fill my layout bench. The next big shipment should be the short block which I'm hoping will ship by the end of next week. -John

@Bonjo2glad the results weren't worse, but sorry your injuries are that severe. I hope your recovery goes smoothly and you are creating havoc again in the garage soon. -John

Interesting @Lightguy, my key learning is that I should have studied Mechanical Engineering It's fascinating how much he has made this car his own. Really admire the craftsmanship and thought process behind it all. -John

Build thread is available on GRM. https://grassrootsmotorsports.com/forum/build-projects-and-project-cars/brunton-stalker-m-spec-bmw-n52/149440/page1/ -John

Here you go. In return, please track him down and entice him to start a thread here about the car https://www.caranddriver.com/features/a38224306/gm-engineer-alex-macdonald-fabricates-sports-car/ -John

Esslinger is building a short block for me at the moment. I know they are busy and can be difficult to reach, so my advice is to be persistent. BTW if you haven't already done so, it's a good idea to pull the plugs and look for signs of detonation. Clean plugs won't mean there isn't a problem, but if they sparkle at least you'll definitively know compression ratio is an issue for street fuel. -John

Congrats on the BaT win @Whit! It sounds like a lot of car for money -- pretty surprised it sold quite that cheaply. 12.75:1 is really high for that engine on street gas. Did the previous owner indicate he was running race gas or an octane booster? -John
