If you look at the science behind shot peening, it prevents cracks forming which would develop into total sudden failure, but it wouldnt prevent the slow fatigue and bend of a rod over time, which is 99% what happens with XUD's as they're always all bent when you pull them from a blown block.

think its worth a bash on hdi rods our not as just looking other things then spending loads of forged roads

Don't know much about it but seems like a bit of a Bodge to me IMO if you want stronger rods just go balls out on forged rods

£450 doesnt sound terrible to me tbh.
but as said its long term 'bend' which ruins them. you go through some projects on here where people HAVENT blown a rod but HAVE stripped engine and it was running but with bent rods due to huge boost! Wishes for more power...
