motavated Posted January 4, 2009 Report Posted January 4, 2009 i have a pro mx motor that is stock bore and a long rod could any body tell me what the displacement would be it has blaster pistons thanks Quote
spurdy Posted January 4, 2009 Report Posted January 4, 2009 i have a pro mx motor that is stock bore and a long rod could any body tell me what the displacement would be it has blaster pistons thanks Long rod doesn't change your stroke length, therefore doesn't change displacement. Stock bore stock stroke would be 347cc. SP Quote
BlntdEyez Posted January 4, 2009 Report Posted January 4, 2009 Long rod doesn't change your stroke length, therefore doesn't change displacement. Stock bore stock stroke would be 347cc. SP If it has 68 mm blaster pistons it would be a 392cc. But if its stock bore like u also stated. It would be 347 cc like spurdy said. Quote
motavated Posted January 4, 2009 Author Report Posted January 4, 2009 can u get blaster pistons that are the same stock bore as a banshee cause i do know they are blaster pistons Quote
BlntdEyez Posted January 4, 2009 Report Posted January 4, 2009 Stock bore for a blaster is 68mm. Stock bore for a banshe is 64mm. So if it has blaster pistons then its a 392cc. Quote

Never done anything with Blaster pistons. How do you use them on stock jugs if they are 68mm diameter? Do they have to be sleeved? Max bore on stock jugs is 66.25mm of 0.100' over. Quote

Max bore on stock jugs is 66.25mm of 0.100' over. Big bore sleeves. This guy could also be running the wiseco 795 series pistons that are 64mm but take away the extra length of the long rod. just like the blaster pistons do. Quote
