Rick's 4.57 break-in & dyno runs
Just a quick question...
From what I read, the best bet is to heat cycle the Rick's gears a few times to break them in, and I've found the instructions on Richmond's site.
Does that mean highway speed ~60mph? ~35mph?
Would it be a bad idea to dyno the car before the break-in?
I ask because the car's at a shop about 40 miles from home getting a lot of work done. They're going to install the gears & Yellow Box, do the baseline dyno runs and then get to work installing the Vortech. I don't want to pay them to drive my car around for an hour (in total) with half-hour breaks in-between and can't really afford to go and do it myself before work continues
But, I'll do what I need to do to ensure the diff remains in good shape.

Street vehicles should be driven at normal street driving speed for approximately 10 miles, then stop and let cool for 30 minutes. Do this 2 to 3 times.

Hmmm... looks like I might have to bypass the baseline run for the sake of the diff and instead take it back to them after I have 500+ miles on the car with the s/c ... which will be 500 very hard miles to hold back on

It's far more important to get it tuned right from the git go. The new gears will be fine if run on the dyno.

Let me put it like this, do it at your own risk.
Personally, I would have them installed last, just before you pick up the car.

hmm... it wasn't going to be a full day of tuning or anything - just three runs on a stock setup for a baseline, but if you've seen problems after only 10 runs, I don't think I want to risk it.

I have to say it, but if you run them hard on the dyno all day, they can be burned up.
