I've been trying to find the formula that roughly calculates out the tbo of
an engine based on power output. I don't think its that accurate but I'm
curious to see what the results are. As an example if the original rating
was 150 hp and the engine was good for 1000 hours how long would it last at
450 hp?  I think its would be about 100 hours if I remember how it worked.
Does anyone remember the way to estimate this?

No way to get there with a simple rule of thumb.  Too many variables.
Not worth spending any time on.   Only actual field experience will count,
and then you need to copy all internal parts exactly, lube type, load
conditions,
etc. to be of value.
