Running process for Cup 240

[garyfitz]

Guys, I have been conflicting approaches for running this motor in. From what I can gather the Supercharger does not matter, so what is the normal process for the Toyota engine, is it 600 miles below 4000RPM or 1000miles below 4000RPM before you can cut loose?

No more that 6000rpm for the first 600 miles. After that you should go up to just over 7000 rpm (so that the second cam kicks in) once or twice for brief periods on each run. If you dont use the second cam occasionally the pistons wont bed in properly.

That is for a NA car? The SC goes on cam at 4k revs so you have to stay below 4k. Check your log book there should be a rinning in proceedure in there.
