Break-In a New Car

Namir

Think of it like a child. If you baby him 24/7 and overprotect him, he's either going to grow up as a spoiled little brat or a pansy.

Occasionally he needs some tough love.

Thats why my break in period consists of ripping through the gears almost to redline.
Modern cars are built with very fine tolerances, they don't need to get acclimated to anything. These aren't delicate pianos. Why do you think Ferrari runs each car around the Fiorano test track before they send them out to customers? Or why Nissan dynos each R35 GTR motor before they put it in the car and ship it out.
Babying your car only makes it slower! (note this theory is not and most likely can not be supported by concrete evidence, but I don't give a sh!t)

That might be taking the baby simile a little too far.

Ferrari engines are hand made.

Nissan Dyno's engines just like any other manufacturer to make sure its up to spec, that doesnt mean you have to beat the crap out of it when you get it.

Whats the point of risking it guys? do a few hundred miles under 4000, then the next few hundred gradually going up to redline till you get to 800-1000 miles. That way everyone is satisfied. Beating the crap out of a car to make it faster sounds a little silly to me. Let everything sit GRADUALLY. Neither the sissys nor the drive it like you stole its are right.

Gradual break in period.

Nissan dyno'ing the engine is beating the crap out of it at it's most fragile state.

Drove it like I stole it after picking it up with 5 miles. 4xxx miles and it runs great.

Why would you break in (prep) an engine like grandma was driving before letting it rip? Makes no sense.
