So my lower pulley recently broke leaving the blower sitting still and I notice a massive difference in my car. Idle smoothed way out, pulling off, 3 point turning in the driveway etc. all smooth as can be. With the blower working I have a lot of idle surging and it's difficult to work the car in parking lots etc. I was just amazed at what a drastic difference there was. This whole time I thought it was just the characteristics of my cams in the new motor but clearly they're very street friendly without the blower making everything go crazy.
I've noticed I only have 8 ~ 10 inches of vacuum at idle with the cams so I called Whipple to see if that's an issue with the boost bypass valve working correctly. They seemed to think that's it and said they have a low tension bypass valve spring option that I should try. Unfortunately this not only requires pulling the blower but I have to disassemble it as well to get the bypass valve out and spring changed.
It'd be really nice if that makes the car have good manners with the blower like it does without. Anyone else with cams run into this?
