Tinkerbell and Chr1s - can you please show where i mention that Honda has tested these engines at extended periods at over 8000rpm??

What i said is Honda and other manufacturers do test there engines extensively at extremes, additionally manufacturers rev limit is normally a safe guard for the engine not a absolute maximum!!

I hope you didnt think Honda would hope nobody ever revved a B series engine above its limits and just hoped for the best! everything is manufactured with a safety net involved

I dare say, a decent set of conrod bolts is important in a engine rebuild for HP applications, although turbocharged or forced induction methods create more stress on the conrods and bolts than what an NA application would , but then again what would i know i have only been building engines for 15 years

We all have different opinions and ways of building engines, as good practice i would replace the mains and conrod bolts with new OEM items

anyways i wont get into this argument any longer, just my two cents
