Good article "Both types of ZDDP offer anti-wear protection, but the gasoline type of ZDDP provides more protection for higher-speed engines (think bigger valvesprings)". There are different formula of ZDDP for gas and Diesel, and race. There is probably some good info on Bob the oil guy.

Box the steering rack mounts to control bump steer. Thanks for sharing. You have nice toys!

Schaeffers Racing oil.

@lotsatsPlease don't keep your project under wraps. Many here would get alot of inspiration mand motivation seeing your progress. Where/how did you do the body skinning?

Another way is find out what the OEM painted it as originally fitted. I doubt Lotus would have bothered to repaint a Triumph Herald steering rack. https://www.gglotus.org/ggpart/sevenxref.htm Black seems to be the answer.

I love the smell of octane in the morning...

Get everything clean, bagged, tagged, and cataloged. or catalogued. Keeping your project clean, uncluttered and organized will go a long way towards progress. Or selling it off to the next guy.

Looks like a proper Caterham. Sdkllkrgss I have 342900 Needs flared wings!

My notes on oil I have collected from several discussions on flat tappet oils with ZDDP ZINC: Driven Racing oil GP1 Brad Penn Lower API spec Shell RotellaT Valvoline VR1 5W30 Joe Gibbs Driven LS30 Performance Motor Oil, Synthetic – 104,487 PSI Zinc: 1610 ppm Phos: 1496 ppm Moly: 0 ppm Calcium: 3515 ppm TBN: 8.8 This oil has too much Zinc & Phos for use in catalytic converter equipped vehicles. It would work well for Race Cars, Street Hotrods and Classic cars. The bottle says it is formulated specifically for high output GM LS engines, and that no ZDDP or additives are required. 5W50 Motorcraft, API SN – 103,517 PSI Zinc: 606 ppm Phos: 742 ppm Moly: 28 ppm Calcium: 1710 ppm TBN: 6.7 10W30 Valvoline VR1 Conventional Racing Oil (Silver Bottle) – 103,505 PSI Zinc: 1472 ppm Phos: 1544 ppm Moly: 3 ppm Calcium: 2707 ppm TBN: 7.6 10W30 Valvoline VR1 Synthetic Racing Oil, API SL (Black Bottle) – 101,139 PSI Zinc:1180 ppm Phos:1112 ppm Moly: 162 ppm Calcium: 2664 ppm TBN: 7.4 5W30 Chevron Supreme Conventional, API SN – 100,011 PSI Zinc: 1018 ppm Phos: 728 ppm Moly: 161 ppm 10W30 Amsoil Dominator Racing Oil, Synthetic – 97,118 PSI Zinc: 1613 ppm Phos: 1394 ppm Moly: 0 ppm 20W50 Castrol GTX, API SN, Conventional – 96,514 PSI Zinc: 610 ppm Phos: 754 ppm Moly: 94 ppm 30 wt Red Line Race Oil – 96,470 PSI Zinc: 2207 ppm Phos: 2052 ppm Moly: 1235 ppm Not suitable for street use. 0W20 Mobil 1 Advanced Fuel Economy, API SN – 96,364 PSI Zinc: 742 ppm Phos: 677 ppm Moly: 81 ppm This is an earlier version of this oil that did not have Dexos 1 approval.

I totally agree. Sevens are 30 minute juant cars. Longer than that requires a special dedication. I quit motorcycles. I found them too uncomfortable. Too hot if properly suited up, too windy and vulnerable if riding in casual clothes.

is the air intake pulled from within the scuttle or foot wells? I have often thought of trying to use footwell air for intake as ir would help with part of the heat issue. Unwanted side effect is dirt is drawn there too.

How could you possibly be uncomfortable in such a wonderful car? 🤭

Frankie, What version of Seven are needing parts for and what parts?

I took a chance on a vintage Formula Ford dry sump I got for a decent price. It needs work so I'm cleaning it up in a rust bath. All done Now its off to get it beat back into shape.

Got this in today from Pierce Manifolds. This is called a "pressure regulator", but based on the function description, I suspect its more of a flow stabilizer. The benefit appears to be that rapid fuel pressure oscillations from engine rev changes are buffered to reduce hammering on the float and needle valve. I don't know if that is a problem typical of low pressure mechanical fuel pumps. Anything that helps keep my float in check is a good thing. What I found stonking impressive is the frameable pincil art on the back of the paper. They don't make stuff like this anymore.

one of the complaints I read about the electronic hall efect dizzys, like the Aldon, is that the rotor can stop at a trigger position thus sending a continuous charge to the coil, until the engine is turned. Is this a situation a mechanical points can have also?

My sluthing today pretty much confirmed that the Aldon and Petronix "are" the same company. Same tech, same failures. Still looking into it. Still very interested in learning my way around a points dizzy. It just seems like it's something a guy should be able to do. So, what's your dwell angle?

I just picked up one of these marine fuel senders Ive seen them on a few crossies with mechanical pumps.

Im wondering if the Aldon I have now will play well with a downdraught carb? Perhaps the Aldon is something I should try before committing to a vac dizzy?

I will be starting from scratch on sourcing an Xflow dizzy. Lucas and Bosch seem to be most common. And one might think between the two, the Prince of Darkness would get the pass, but then maybe not. I now have to take Dizzy 101 and see what the Formula Ford and Escort boys are using. Im already setting rocker gaps I might as well set points gaps too. I will have a E-bomb proof car for sure.

Steve, youre about to make me a points man. I'll never touch a data cable again.🤓 My last laptop was 2004. But youre right, separating ignition curve from actual curve can be problematic. Someone has the clever idea of relocating the condenser back to the scuttle for swapping out different values.

Steve, sage dizzy advice that will gi into my dizzy notes. But looking for the context here...🤔 Are you saying that I need to go back to points & vac with this carb? My current dizzy is an Aldon setup for DCOE 40s and A2 cam, no vac. A detail I hadn't noticed till now, the manifold the carb was attached to, for a Cortina GT/E, doesn't have a vacuum nipple, or an obvious port on the carb. 🧐

Yea you're right. the jetting is based on the chokes in place and working. If Im a carb guru swapping tubes and jets, etc, I could dial it in. Which I still may need to do with my A2 cam profile.

Please share you findings!
