I've been trying to find the formula that roughly calculates out the tbo

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?
