To be honest his thread is why I'm curious as to whether any gains will be seen, from Erics comments I don't exactly get the feeling that his car has turned into a fire breathing monster if you get what I mean. So I'm in two mind sets I just wonder what forcing air into a supercharger from another supercharer will do...I'm looking at the vortec V7 I think it has an internal transmission so no need to have oil lines. It's around $2k so I need to be sure I'll get gains otherwise Itl be a big waste of money and effort But I think if it works it could actually be a cheap way of getting mid to high 11s consistently
