Answering your performance engine building and tuning questions
Daniel Trot has asked what would be the best way
to setup a run-in map for fuel and ignition
for the startup of a new motor?
Same as a full power, or pull the ignition out
and bump the fuel up?
Look, really that's a common question,
but really the answer is that if I'm doing a run in tune
for a car, I'm not really dealing with it
too much differently than if I was tuning
an engine that already been broken in.
Definately you wanna be a little bit careful
about trying to run too rich.
This is gonna be counterproductive
and there's really no need and no advantage to it.
I may however choose to be a little bit more conservative
with my ignition timing,
and definitely if the engine is turbo charged,
I'm gonna be running a lower boost target
during that run-in portion of the engine's life.
Probably really a good point to make here as well though
is I think a lot of people believe that you need to go
and put four or 5,000 kilometres
on a freshly built engine in order to run it in,
and it's just simply not the case.
With modern ring technology,
modern boring and honing processes,
the break-in process is accomplished
within no more than about 200 kilometres.
And in fact, probably the majority of that break-in
occurs in about the 20 or 30 minutes of running.
So really it's not a case of needing to put thousands
of kilometres of running on your engine.
