have you done anything to monitor fuel pressure or prevent fuel starvation such as a swirl pot etc?
my long term plans for my track 200 is to supercharge it so genuinely interested.
I melted a piston in my other track toy, car was going great at silverstone then just lost a bit of power and turned out it had det and a hole in one piston (it’s a V6 with over 600bhp at the time)… was impossible to diagnose (mapper also dodged my calls) as the original ecu didn’t record anything or have any safeties…. I moved to a motec ecu at great expense but it paid for itself with 2 further avoided blow ups when it caught fuel and oil issues and cut power…. I’m now a firm believer in having a proper ecu with safeties etc to manage modified boosted track engines.
