Redlining
 

About how many miles did you start aggressively use your car? As in
Redlining. Right now I'm at 300 miles,driving it pretty soft, easy and its pretty tempting to just put it down and go though some gears.

I picked up the car on a Thursday, drove it for 400 miles before Sunday. My son and I then did an autocross on that Sunday. No babying the car there, I just had fun with it

Op no harm in babying it as directed. Personally I waited untill I had my first oil change before really runnin through some gears.

Personally, I am a believer in a hard break in once everything has come up to temp. The first couple hundred miles is where everything is going to wear clear & set up. In fact, the GTR's engine is red lined from the factory for a full 10 minutes straight. Yes I know the Z does not have a clean room build motor like the GTRs , but you are not red lining for 10 minutes straight either. I have done hard break ins on all my vehicles, bikes trucks & cars with good results.

Here is an article supporting my thoughts Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

YMMV :tiphat:

I know of several motor builders that do the same. Right after the build, throw it on the dyno and run it.

Dealership had the car at ~200 miles in. I redlined out and for the most part home.

This has been discussed, try searching. But essentially there is no agreement

Bought my car, went to the drag strip that night. I was able to put 300km's on it that day before the drag strip.

I only had 4k on mine and put a GTM SC on it @ 471rwhp.:tup:

Hey man your from camarillo also? Such a small world lol

My advice is, drink a 6pack of redline then put it in 3rd gear and hit the redline all the way home. Its the best way to break in your car. A lil redline in the gastank helps boost power as well.:tup:
