I never thought about a megasquirt. However, I have a gravity system on HellHorse, so I really haven't ever had an issue. I like not having a fuel pump... one less thing to go bad...

I use the Lucas ZDDP additive. It is a must for my high horsepower and high rpm engines. I try to use Mobil-1 oil which has some ZDDP in it, as well as Royal Purple Racing formula, which has high ZDDP additives. I don't think oil conversations should necessarily mean "war" ...I really like exchanging ideas. Here is what I use! https://www.amazon.com/Lucas-Oil-LUC10063-Ounce-Engine/dp/B001DKN8ZU/ref=sr_1_2?keywords=lucas+zinc&qid=1639511890&s=automotive&sr=1-2 Don Share this post Link to post Share on other sites

I began using it then, and have used it in every racing engine I have built so far. I find no cam lobe or follower wear with this additive. I also believe that it helps with rod journal wear... but I think ZDDP is mostly to help stop cam lobe and follower wear. Don 1 Share this post Link to post Share on other sites
peter lena 8,634 #58 Posted December 14, 2021 @Snoopy11 , yes since using it in all my small engines , they have taken on an ease of running that they just simply did not have before , my stand by generator with a 3600 rpm run range , just cruises along , definitely easier and smoother than before. combine that ease of run with a 2 spring pull on your throttle cable arm , one spring assists speed up the other slow down , makes the cable work much easier . pete Share this post Link to post Share on other sites

I was waiting for you two to start talking about the metallurgy processes in connecting rods next😀. I am impressed what can be done with a single cylinder engine. Now I know who to ask for performance advice. 1 Share this post Link to post Share on other sites

Billet is heavy but its stronger, powdered metal is also quite strong but...can you trust the process? Bearing inserts should be standard on small engines. 1 1 Share this post Link to post Share on other sites

I have to admit, that is very interesting to me. I am going to have to think about that one. Maybe due to super-heating of the rod...? Don Share this post Link to post Share on other sites

I did think the same thing about the bottom rod in the pictures... but my eyes could be playing tricks... I'll put it this way, that bottom rod in the pictures does not mimic cast rods that I have replaced/removed. Don Share this post Link to post Share on other sites
Howie 886 #72 Posted December 16, 2021 Friend of mine has an engine shop builds a lot of circle track engines. Have seen quite a few laying around looking like that. Have seen some like the bottom one but can't recall who makes them though. 1 Share this post Link to post Share on other sites

That photo is from: https://forums.nasioc.com/forums/showthread.php?t=2835423 Scroll down to post #8. It is an steel turbo H-beam rod.

Snoopy11 5,714 #74 Posted December 16, 2021 More research... both rods are 4340 steel H-beam. The bottom photo's difference is just a photo mirage. Those are used in automotive supercharging and turbo engines. Not available for small engine use. Back to basics... cast rods break. Billet aluminum bends... just not "easily" ...but won't break.
