some news:
i finally got the reinforced chargecooler from radtec, after 2 months, but nevermind
well, the chargecooler is heavier than the first one i got, and looks stronger
but i went to Le Mans this WE, for 2 days of intensive track driving.
on my last session yesterday, after 500km on track, the chargecooler exploded again, the weldings cracked on the side, where it was not reinforced. i can hear the side panels are not as thick as the others ones.
i spoke to the guy of Performans engine who told me he exploded 5 chargecoolers! he finally managed to get Pro alloy make him a reinforced chargecooler that doesn’t explode/crack
