What did you do to your Hellcat today?

My input on an idling engine (a performance engine you care about) is to not let it idle at a steady RPM, but to vary the engine RPM up and down.

The idea is to not let those rings wear in at idle which can create a "land" that the rings have to bust through once they get into the upper RPM range and everything stretches out.

When I'm warming up an engine, after about 1min or so, I'll start gently varying RPM up through 3000ish, no hard rule, just not set at one RPM.

And I always try to hit max RPM at least once when I'm driving, keeping that land from being created on the non-stretched side of life.

Get what your saying over years, but I wouldn't think a couple minutes at a specific rpm would wear away that much material. I mean usually when you reborn an engine your not taking out that much material to return it to a true bore size

And they probably will..although not worth much if and when you decide to sell (depending on how far over 200 you go..)....

Happy with 160k on a v8. By then the chassis needs so much work it's now a junker

Idling is bad. Period. The EPA ratings are based on idle and cruising. Tim Kuniskis was on a video saying that epa standards don’t take into account for power enrichment, which happens the second you step on the gas. Thats where they have all of their flexibility and why they’re able to do what they do

I heard normal idling was good as it allows the engine to rest and settle down. Like all the material will relax because it's not under a load.

Not sure that’s how that works, once everything is up to temp it’s up to temp. Thermal expansion
