I talked with ARP tech support and explained the details, dimensions and concerns I posted in my previous messages.
He said the ARP fasteners (p/n 250-2201) are too short (both shoulder and thread) for my aftermarket application; they are intended to be a high strength replacement for OEM fasteners.
He recommended a minimum thread engagement of 1.5 X Dia., and preferred 2 X Dia. for this application in an aluminum flywheel.
Concerning my use of Grade 8 bolts without a shoulder....not the best choice.
He said most race-only clutches have dowels to control the shear force. The fasteners primarily provide clamping force (tension). The typical street/strip flywheel/pressure plate assembly depends on the bolts to control tension AND shear, therefore the shoulder on the bolts play a crucial role. The shoulder should extend through the pressure plate cover and as deep as possible into the counterbore without bottoming. (Repeat...without bottoming!) This should be a close-tolerance fit and it will provide maximum shear strength. (This echos what Patrick mentioned in his previous post.)
Sounds like I need to replace the pressure plate bolts.
Also, Patrick, I used blue Loctite....I was concerned that with the red I might never be able to remove them.
