[Fot] TR4 Race Engine Break-in Questions

[Paul Ricco]

FOT,

Good afternoon and we hope everyone is having a great weekend.

We have a couple questions for those who have had experience and success building TR4 race engines.  The information might be helpful others on the forum as well.

1.  We have seen a few different recommendations for initial run-in.  They seem to range from 5 minutes to 20 minutes at approximately 2000 RPM’s.  How long and how many RPM’s are people running them  for?

2.  How long are people leaving the break-in oil in the motor?

	a.  Are people taking out the break in oil right after the run-in and replacing it with regular oil before leaving for the track?
	b.  Are people running a few sessions under load at the track with it in and then switching?
	c.  Something else?  If so, what are you having success with?

Again, we are really gearing the questions towards race engines due to complication of breaking in the race motors at the track with limited time and the track session schedules.

We are trying to avoid re-starting the entire referendum up on oil brands again, so we apologize if we do.  We are really trying to get to how people are breaking-in the TR4 motors successfully.

Thank you for considering my questions,

Paul Ricco
