your take on BOV's and WG's
Im familiar what they are and what they do as well as the fact that Im gonna need both, Im just not sure if the sizes should be any different, or if I should be running a wastegate on each bank or one just before the turbo.
The intention is to stay nearly completely out of boost untill atleast 3500 while under cruise/light throttle.....no more than a pound or two, simply to keep the cars current street manners.
Turbocharged engines often produce more heat.... heat that expands the top two piston rings to a greater degree than a normally-aspirated engine would.
To acommodate this increased heat, the ring end gap will likely need to be increased to an amount larger than the same engine without forced induction would require. If insufficient end-gap is present, under lots of heat, the gap totally closes and the ring tries to continue growing, and can seize in the bore, possibly damaging the bore, and sometimes literally pulling the top off the piston at the ring-land.
Additionally, pistons that are designed for forced-induction applications, have the top ring positioned lower, with more room between the top of the piston and the top ring land. I don't know for certain, but I think its a strength issue.
I have successfully used a set of OEM Magnum pistons in my 360 Magnum, probably because I only run 10 pounds of boost, and because when I built this junk, I didn't know any better.:angry7:
Build a 30-psi /6 turbo motor, and you'll find out how much you DON'T know, fast... That's what Freddie and I are TRYING to do...
I'm still learning and I have a L-O-N-G way to go.... obviously!
