After fitting the Raptor supercharger to a VE SV6 will there be a need for any other modification to achieve bigger power output?

Should be great to see when it’s done.At the moment though, the alloytec has more scope for performance upgrades for higher power outputs. Standard though, the SIDI V6’s generally go better than the Alloytecs. Long story short, if you’re chasing big power figures from a V6, the alloytec would certainly be the way to go
