very helpful stuff mate thanks. i think the xtreme is the way im leaning, just for future scope?
do you have any idea what size supercharger pulley i should go for, its currently running a 6psi pulley im unsure of what size that actually is?
currently running around 400hp at this pressure, if im going to spend the money on standalone and mapping, then i would like at least another 100hp ? any ideas on pulley size, and also i suppose i may have to upgrade to 8pk or 10pk pulleys and belts to stop the belt slipping.
