[QUOTE]Originally posted by 93PONY: [QB] [QUOTE]Originally posted by stoauto: [qb] [QUOTE]Originally posted by 93PONY: [qb] Main cap girdles are near worthless. If aluminum they can actually do harm to the motor (expands at a different rate than the Iron mains & can push the main away from each other unless there is 'play' in the girdle where it mates to the studs.....in which case what good is it?). If you must have one, steel is the way to go, but it will not keep a stock block from splitting at 600RWHP. [/qb][/QUOTE]blah blah blah.... tell me something new shaun. :p hehe i know it wont stop the block from splitting. but by tieing all the caps together and by making them like one, it really helps to prevent the caps from moving forwards and backwards. it also helps by preventing the caps from jumping up and down which is what can happen during detonation. :cool: [/qb][/QUOTE]How can a main girdle hold the caps from moving around? It does not possitively lock the main caps to the gridle....not like a rocker stud girdle that possitiviely locks all poly-locks & studs together. A main girdle sits on top of the caps....just like a washer & bolt head does. If the caps are going to walk with a washer/bolt torqued to 75ft/lbs, they'll walk with a girdle on top of the washers torqued to 75ft/lbs. The bolts/studs are a fairly loose fit in the main caps. Tying all the bolts/studs together will help the studs/bolts from moving, but the caps themselves can still move around the bolts/studs. With clearances in the .0015-.002 range, any amount of movement can be detramental... If the main girdle does not possitively hold the caps themselves, it can not hold the caps from walking. As for the caps jumping up & down......I can see it helping out there. Then again, don't detonate the bitch! :D Aluminum girdles can be a bad thing....simply because the aluminum expands at nearly twice the rate of Iron & can push the bolts/studs which can affect clearances. For this reason the aluminum girdles out there are not a 'tight' fit... Most think that girdles are neccessary when power exceeds 500RW...as if a girdle is going to give them an added measure of saftey at high HP levels. By design it's ment to control cap walk at high RPM's... (which id doesn't do very well). It's a big-ass marketing ploy if you ask me. [/QB][/QUOTE]
