Droop Rule and State of DLM Racing

[DV8]

Did any cars burst into flames this weekend? Have any cars burst into flames since the extinguisher rule was implemented? I really don’t know, I only read here but it seems like someone would have posted that the dirt LM onboard system saved a life. Do we need the rule?

If you guys don’t want to run the series don’t run it, or cheat the chain like we do with everything else in the sport. I’m almost positive that no tech person has enough sense to bounce the LR to see if it stretches. I wish I was a smasher so I could drive these LM sprints.

Obviously they will be checking the chain ...

They don't have anything to check it with, unfortunately. You could load this chain all you wanted and you'd never know it has any spring effect whatsoever. It's VERY stiff, and really only provides any dampening at the extremes of loading.

So even if you use it you won't gain back the height you lost, just a little dampening at full travel.

Okay Brian Gray, here's an easy enough question. Who is your supplier? There are 2 patents on spring rated chains, and I'm involved with both companies. It's not like it's a secret who they are, so please elucidate!

Anyone can make a spring steel chain.

Anyone can make a spring steel chain.

Sure can, but make it the same strength of high quality chain AND able to dampen a specific frequency range (fairly wide) very effectively? That's a very tough proposition that fortunately material science has caught up with, and only very recently. Hopefully people won't infer that this was developed for anything racing related, because it's intended application couldn't be further from racing.

If a ft long piece of chain would stretch 2" with 200 lbs of load on it , it's going to be pretty obvious

Absolutely. I don't know what Gray invented in his top secret speed factory, but the chain I'm referring to only has 4-6% elongation.

So any possible gains would be so minuscule as to go unnoticed on the stop watch. No worries, just snake oil.

Are the patents referring to steel chain or another material?

Im pretty sure a rubber type material could be made into a chain.

A composite would be best for built in damping.

Steel chain.

What would make you arrive at that conclusion? What do you think are the goals of someone using such a chain? What percentage of elongation have you determined is necessary for any appreciable benefit?Where was the implication that it was worth any speed? Snake oil would imply someone was trying to convince you of the purported benefits in hopes of making a sale. You'll not find that I claimed it to have any benefits.

I was agreeing with you... The percentages you listed were quite small in the grand scheme, so to me its a non-issue as to whether a person need be concerned with getting beat by a chain that barely stretches/springs.

My apologies, I took your post the wrong way. I started drinking early today.
