engine brake in ?
i recently blew up my stock z6. i have another z6 that is being built (tt rods/vitaras) for my crx but money is tight at the moment so ill be putting that motor in my coupe.
question is, HOW DO I BRAKE THE MOTOR IN ? or better yet, BRAKE IT IN N/A or UNDER BOOST ? i read this http://www.mototuneusa.com/break_in_secrets.htm and it said to "run it hard." but the motor will be untuned for boost, so should i brake it in n/a ?? or brake it in while tuning for boost ?? lmk what you guys think. thanks. SETUP: z6 block w/ tt rods/vitara pistons pp y8 head w/ stock cam/valve train ebay t3 "super 60" @ ~ 12psi stock fuel pump 450cc injectors stock map sensor |

Breaking the engine in hard is not my choice, but the motor should see da variety of RPM's, I let the motor gain RPM (well before redline) while driving then let off the gas to let the motor slow the car down to bring the idle down low. Repeat. |

ok while were on the subject,
i got a base tune im my car and the afr are around 9.4-9.8, now im building up my new engine 8.7:1 comp ratio the stock car is 9.2:1 but i dont have my tunning software yet. now im thinking that the afr will lean out but by how much, will it be safe to run the engine like that for a month at 8psi untill i buy my tuning software and btw the software is 350$ fucken rip off but whatever. and if anyone has a copy of the proracer software for the sct flash unit. hook it up. i better things to spend my money on. |

Motors are best broken in on 20+ psi.

Re: engine brake in ?
Dont break any engine in, NA or boost, if it's not tuned.
Too lean, you ruin your sleeves. Too rich, you ''wash'' out your rings. Tune for afr's first, then follow the instructions on that website. |
Re: engine brake in ?
but is 9.4 - 9.8 too rich
