also are you planning on using the bypass system that the mini uses? or just blank up the hole in the inlet of the supercharger?
Looks like i have a lot of research to do!
I wasn't aware of a bypass but the whole point of my project is to try to get as much usable power and torque out of my twincam without blowing it up yet using the car on a daily basis. I'm going to experiment with redistributing the weight throughout the car as well to get it to handle better once the g-max lowering kit has gone on but another goal is to shut-up a certain cosworth saph owner who takes great delight in telling me that my T-C is s#*t compered to his "Cossy".
The reason for opting for the supercharger over a turbo is partly personal due to my name-sake (W.O. Bentley) using one to show the likes of Ferarri how it's done!!!!!

but also I like the way the power is delivered

. And besides, If I wanted a turbo Sierra then I could just buy one but as an engineer I prefere the challenge
