Ahhh, Aaron, I knew I'd get to hear from you on this one. You know, float is right about the "break-in" thing in the fact that you don't need to be a total twit during the young life of a freshly built engine. I know you have direct connection with a good engine builder (i've seen his work and saw his car perform), but it has been apparent that theory of breaking it in like you're going to drive it is the clear-cut way to do this. I think if it's built correctly, it should withstand whatever you thow at it.
As for the reason why I tore it down, low oil pressure. We put about 14miles on the car and the oil pressure was junk. I wasn't happy with the oil pressure, so I made the tentative decision to pull the motor back out, tear it down, check tolerances, mic the crank, and sent the whole engine to a different machine shop. The crank mic'd-out to be within spec, but the machine shop opted for a .010 cut as well as re-polished for a good fit. Had my friend's get me another pump, cleaned the bottom end and head, blasted all the oil galleys with compressed air, re-assembled motor, threw engine back in car, cranked car, and she fired right-up. Compression checked-in at a perfect 160psi per cylinder with no consumption of oil. The car runs good and it gets constant gear changes while on long commutes: 1st gear, 2nd gear, 3rd gear, 4th gear, 3rd gear, 4th gear, 3rd gear (You get the picture).
Ryan, your way is the way for me and that's why I practice that method. I got the strangest feeling that this car is going to be something to talk about in the near future. It drives around with a 60-1 blower spooling like it's ball bearing piece or something. And when you cut the car off, the blade just keeps on going for like 30-40 seconds. I still need him to ride it some more before we go to the dyno with it. The car revs extremely clean; even had a discussion with the SDS techs about the fuel #s I'm using and they don't even believe that the car is idling with those injectors. Anything is possible............
