Just thought i’d share that I’ve recently had a host of cooling upgrades done and a remap of my Cosworth Stage 2.2 Supercharger setup which made close as makes no difference 302bhp. Stock engine, stock fuel pump, stock coils and still factory front cat. Only engine upgrade being some cooler grade HKS plugs. Matt @ Cosworth was quite happy that I was perfectly safe running at this level and said I have plenty of margin left to stay reliable.
I’m fully prepared for the fact that one day a rod may give up the ghost and i’ll need a rebuild but I just thought I’d share that he was happy that 300 was safe and no need to map power down to 280.
