80 hours is the recommended time for the engine to be used in competition e.g. at full load. In order to preserve engine life, we suggest the engine is not used as a road car, this will put less stress on the engine but obviously you are still running the engine and all engines wear out. If you drove it only as a road engine, the engine could be extended considerably. The 80 hours is advisory and we would normally expect to see minimal wear as we originally described big end bearings. Obviously you should always monitor pressures and temperatures to ensure they always remain consistent and if variation occur checking everything then is a safe preventative measure.
Some of our customer choose to considerably longer times between strip down inspection, but they take particular care with their data analyse and again check the engine if something seems to be different to expected. You might find other engine suppliers or builders may promise you longer inspection times, but we prefer to be ultra safe and do not like to hear the words 'oh we have never seen that before, I think you now need to buy a completely new engine' so extending the expected engine inspection time can have huge advances for the engine supplier.
We are only giving you a recommendation to give you the longest possible engine life with minimal maintenance. Most of our customers' engines last for far greater length of time with minimal maintenance. We use the highest grade of components that are extensively tested by ourselves in serious competition before being released to our customers.
