Pedal box interest?

[Pagan]

Hi all…

I am considering having a pedal box CNC machined…. Would there be any community interest in these if they were available?

If you look at the MVP web site, it looks like they have a reproduction in the works...

Hydrautical?  Is that even a word? 😄

Given MVP's efforts, I'd say the overwhelming answer to your question is, "Yes, we would very much be interested in a good option for pedal box replacements."

 

Sure as heck know I would...🙂

[TobyB]

Ahhh, yes, hydrautics.  I do believe those date back to the days of the overcomplicated bong....

supportive of the idea, but already has enough pedal boxes for the time being.

[oldbugr]

I would be interested. Let me know. Appreciate  your effort.

What would be the features (and why cnc machine).
I know there's a guy in france making pedal boxes with dual master cylinders and a balance bar, but as the balance bar isn't adjustable while driving it's useless as such.
I fitted my pedal box with needle bearings both radial and axial which is a good thing.

@uai whats involved in using needle bearings instead of say what IE or Blunt includes in their refresh kits? Links to the bearings you used?

[uai]

I found the IE or blunt kits with miniature roller bearings not suitable. As the Roller bearings are used beyond their allowed capabilities.
I'll use the german terms
So what you'd need is a Passschraube with a precision ground diameter to replace the standard bolt.

Then a reamer to bring the inner diameter of the pedals to a precise diameter so the needle bearings fit.
I then changed the width of the pedal tubes so the axial needle bearings together with the precision washers fit the box - this allowed to mod the spacing of pedals a little - in my case I moved the brake pedal a little closer to the throttle - have interference with the carpet in mind.
There are some differences in the pedal boxes over the years in my case it was pretty straightforward apart from machining the pedals for the axial bearings. And you won't be able to assemble the thing in the car with the Passchraube.
I haven't go a precise Bill of Material but I dug into my purchases and know what I bought - this is not 1:1 what was used I had some surplus and unsued stuff. And I have the early pedal box without booster.

I cannot describe the feeling of dread that I have as I look down the barrel of having to rebuild my pedal box.  I have been putting it off for years.

Pedal boxes aren't bad.  They DO benefit from occasional maintenance and cleaning.

While I agree that it seems silly to not go the extra few meters and make it on-the-fly adjustable,

I'd much rather race something that was infinitely adjustable rather than not.  Yes, it'd be a time soak to set,

but when you need a bit less rear, it'd still be really nice to come in, adjust, and have it done rather

than be stuck with it.

There's also the 'no brake adjustments are allowed while in the driver's seat' rule in some classes.

 

and Dang, that's 200% overkill.  I like it.  I personally am not good enough at maintenance to deserve such a thing...

CNC because everything should be over engineered and overbuilt so I never have to worry about it again! 🤣🤣

I did my friends about 2 years ago and it wasn’t all that bad tbh. This was before I knew anything about 02s. I made sure I had a diagram off RealOEM and just laid everything out on a bench as I took it apart and cleaned it.

The oem set up only lasts for 50 years, lets reengineer the whole thing so it'll last a millennium😎.

I hear of lots of DBW chatter for EFI systems.
