"Well, I guess you can always make the engine tougher to prevent dangerous operations with turbo on board. And, if u wish, lower the compression so you can load more boost, but then that ruins the whole point of vvtl-i." I hear what your saying Danz. but with the supercharger it will help it in the lower end but the power is not that good. I looked at your point with the Vvtl-i with my mechanic and im not to sure if i should run the boost all the way through the vvtil or stop it just before it kicks in. My mechanic reckons that i should run it all the way through.
