piston to wall clearance for diamond blower pistons
piston to wall clearance for diamond blower pistons what piston to wall clearance are you guys building your motors to or having them built to for 2618 diamond pistons for a blower motor? the spec card with the pistons says .0035, than in the extra paper that came with the pistons it mentions clearance again. like .001 to .0025. are they talking about an additional .001 to .0025 on top of the .0035? the motors Ive built in the past for people using lots of nitrous with a utetic piston or a forged piston were in the .003 range, this is my first blower motor so I just want to double check with people who run them. Thanks.
I spoke with a highly knowledgable guy at diamond before I ordered my pistons and he recommended 0.006 piston-to-wall clearance for iron block and 0.0055 for aluminum (because of the piston chasing the bore some in alum).
I can't remember his name but I would highly recommend calling Diamond and discussing your setup and getting the recommendation straight from them.
