What did you do to your Hellcat today?

[RetiredFirefighter]

I just want to report that I didn't do a single darn thing to my Hellcat today!

Of course, that might be because I don't actually own a Hellcat.😄😉😎

Two competing issues.

The highest wear rate is on a cold engine, AND metals improve their wear characteristics when they are hot as well as mechanical clearances shrink to correct values.

Do you want to reduce the time of "highest wear", OR do you want to reduce the load from operation (piston pressures and velocity, etc) during the period of time that the engine is cold?

You can't have both.

I choose to reduce load and gently vary RPM.

So just how critical..(or cumulatively significant) is what we would consider the wear rate of a modern day cold engine start...on say a tear down of a 45/50 thousand mile engine...how far outta "new" spec would it be any idea

THEN WHY ARE YOU HERE

No clue

No clue

Not surprised....not sure many...(or any) on here would know...It would seem far too many variables to consider or factor in....my guess..not enough data...or evidence to support either procedure....if so factory warnings would be more specific or emphatic.on such procedures...just my .02
