Redlining your car

Ah yes, the Bullitt/Mach 1 Coyote vs the base C8 LT2, that makes sense.

That's what he was arguing for. In his mind somehow the LT1 wasn't a valid comparison because it made less power than the Coyote, therefore it invalidated his argument that the LS platform is "objectively superior".

The guy I was arguing insisted LT1/LT2 is over 100lbs lighter but I couldn't find undressed versus undressed weights anywhere.

That guy had to have been thinking about the iron-block modulars.

Good stuff. I agree the Gen 3 Coyote feels more advanced in tech. than the LT1. Have you read this article about the development of the Coyote? They tortured the crap out of it.

"Besides meeting the performance goals the Coyote had to pass all of Ford's standard durability tests. These dyno sessions are incredibly brutal, always far exceeding what any rational customer would do to his engine, and occasionally surpassing what is physically possible in a car.

We observed some of this internal combustion water-boarding, and for anyone with a foot-pound of mechanical sympathy it isn't pretty. Engines run fatigue cycles equivalent to 62 Daytona 500 races. Others replicate customer drive cycles for 1,000 running hours to include 1,000 cold starts, plus hitting its peak torque and power for sustained periods. That test alone runs 100 hours a week for two and a half months.

We witnessed another torture session where the engine was run at WOT for several minutes, the headers glowing just a hint of red, then the engine shut off and after several seconds of sitting, -20 degree ice water was forced through the cooling system. Frost formed on the test rig as the engine was about frozen to death, then the ice water stopped, the engine started and after a handful of seconds idling was taken back to max rpm, max load for another heat cycle up to 225 degrees. Each complete cycle takes about 10 minutes, and the engine must survive days of these non-stop thermal shocks."

I think I did, but you know, with engines, anything worth reading once is worth reading again
