break in procedure
i was wondering if there is a big diffrence between the break in procedure of piston rings for n/a and forced induction.... i have rebuilt my motor and i am about to start to break it in however my fmu is not back from vortech yet and i want to start to break it in because i have a race in a couple of weeks and will have limited time to break it in and need to start asap(but i dont want to chance running my turbo without my fmu)..... so my question is if i can break in my car n/a and then ad the turbo at the end of the break in period if that would effect the rings seating diffrently and cause premature failure when the turbo is finally put on.... or would it be in my best intrest just to do the break in with the turbo on.... any help or information would be appreciated

Re: break in procedure (zdr262)
I'm more of the school of thought that you should drive the engine for a couple miles and make sure everything is fine, then do a couple runs to redline in first and let the engine decelerate the car the do it again and again to seat the rings. Do you think race engines are driven gingerly for hundreds of miles after they're bult?! I'd think not.

Re: break in procedure (ion_four)
hehe, ion's got a point. I was going to comment that I follow the break in w/ boost if you're going to run boost. But keep in mind that most people bolt on a turbo kit onto an engine that's been n/a all its life. Granted its well worn and hopefully seated properly. I see your point, both choices seem equally fine.

Re: break in procedure (DSF)
Also, the other companies that have turbocharged vehicles break in their cars with boost. I mean, you don't go buy a WRX drive it around for 1000 miles then take it to the dealer to get a turbo put on. Also, if the rings don't seat in the first 5-20 minutes of idling, it is very likely that they will never seat. The only thing I would think you would need to take your time with breaking in would be the valvetrain, not nessecarily the bottomend. I mean, the turbo wont produce boost till like 4000rpm, so shift before its making boost.

Re: break in procedure (Boosted Ego)
We have not broke in my boosted built ITR engine with 20psi boost. The car run great and don't burn any oil at all. Nowadays engines need no break in time.
