Forgive me for my stupidity when it comes to this stuff. I'm not as savy as many of you when it comes to engines. I'm trying to understand when the greatest load is put on an engine? I've been reading some posts on various forums about engine break-in and load. I always wondered how you can give the engine high load, but keep the rpms below 4k or so to comply somewhat with the owner's manual. I have a manual transmission so would flooring it in 2nd gear until the rpms hit 4k be considered "high load"? I thought increasing the rpms through the gears was high load but according to some it's best to start with the rpms low, and floor it until about 4k rpms. With an automatic, if you WOT you automatically hit the redline almost. With a manual, it seems much easier to WOT without raising the rpms. Does this make any sense?
