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
