Just curious if anyone happens to know the specs for the supercharger lid bolts? I am going to pick some ARP ones up.

I'm interested in this. I'm assuming if you can get some ARP bolts they would be reusable?

Thats my intent indeed.

The lid bolts are reusable, it is the supercharger to head bolts that are one time use.
M6x195mm.
Something to think about on those bolts:
1) they have a sealing washer between the bolt head and supercharger housing
2) they have a 'centering/anti-vibration' insert just below the bolt head

both of these can be reused, with perhaps some sealant, but they may effect the torque of the ARP bolts. IMO that should be discussed with ARP to see what they say

Thanks, just wanted to check on the ARP bolts anywho for the lid. Not removing the blower (which I believe is the pic of the long bolt you listed right?) Any idea on the specs for the lid bolts?

there are two different ones, 15 of the 'regular bolt' type and 5 of the bolt with a stud.
the threads are M6, i don't know the length, but they're all the same length below the head. pull one of yours out and measure it.
the pic is representative of the bolts..........they're some spares i had.

I just found this out in the hardest way..... Now I must dig it out..... Damn. I'm ordering a new set now. Tomorrow the fun begins. taking the supercharger completely off to extract the remainder of that last bolt.... Brand new torque wrench also.

GM 12679527 bolt and gasket kit, it has everything you need. Not sure about the availability/lead time for you though
