Well, I broke mine in around i think 3000 miles. What you DO
is drive no faster than 55 MPH and try not to go over 3000-4000 RPM. After your first oil change you can exceed 55 MPH, but not two fold! Still baby your engine cause the parts need to get strengthen themselves.
What you DO NOT
do is race! Putting you engine through a lot of stress due to high RPMs is very very very very BAD! The RPMs should be kept at a minimum. Even though you have a fast car... its still a baby. The engine needs pampering.
I broke in to mine at 5000 miles, then I raced a spec V, who just got his and killed him....
sucks to be him. I think he didn't understand the whole break in process. I raced him again and still beat him... maybe the third time will be his charm...
Your car won't be able to live up to its potential if the engine doesn't properly run.
