It is an accessory to the supercharger. It is not part of the kit.
This is an experiment that I am in the middle of. As part of the continued avalanche of exploding projects this year, I am attempting the fourth revision of the thimble keeper I first built about 7-8 years ago. This version is for my new FluxOR aluminum bumper and I decided I wanted it to be a form fitting hook that won't damage the thimble when others are setting up my winch line.
It also needs to be very compact given the limited real estate on this bumper compared to my current one. I decided I am going to sculpt this thing out of acetal. I do not have a lathe or milling machine.
This is the general profile.
The hook is going to be shaped like the teardrop eye of the thimble. I made a pattern to copy this and attached it to the bottom of a copolymer acetal cylinder.
From there, I built a very crude cradle for my die grinder...
...with a finger shaped like the carbide burr that will trace the teardrop pattern and grind that into the acetal as I rotate the cylinder.
The first pass worked very well. This is the center height to eventually match the thimble height with the fairlead opening.
The next steps are to change the height of the die grinder and also shift the position of the template to sculpt the hook.
Halfway done!

Is there any data on what the ingredients in those various products will do to an o2 sensor? Seems the less colorings,dyes and soap the better?
All I know is the SDS states 30-35% meth and less than 3% ethylene glycol.
On the occasions that I need to use something like Peak or the blue stuff, it would get further mixed with HEET 100% methanol. That dilutes the glycol more, if that matters to begin with.
To be upfront, I also do not know if I need meth injection. I did it out of caution thinking it would at be at least a safety net.
Can you get 93 octane where you are? Fuel will be a big driver as to the need. As I’m sure you know, what you are guarding against is detonation.
Yes and I'm aware. Early on during the first install, there was a violent moment of pre-detonation before I reinstalled the factory fuel injectors.
Good. Now design me another new intake with a place to put one or two of those.

Can you spot the intercooler here?

I don't want to take all the fun out of your design challenges!
I can. I would be reluctant to lose to cold air intake and also figure out how to attach the throttle body
Haven't screwed it up yet!
The die grinder gets raised and lowered to create the correct width for the thimble.
The template gets shifted to create the hook.
Some rough sanding to begin removing the extra material for the final shape.
And a test fit!

This is about where the new thimble keeper will go.
