Flux's 2's, Silver 62 single turbo / single pump = no rattle
Flux 3.3's , Twins 62/480, dual pumps, (Decompressed) = LOTS of rattle
Flux 3.3's, Same performance stuff but a bit higher compression = less rattle but still there.
Flux 3.8's Same mods with slightly decompressed Monotherms = Rattle (not as bad as decompressed motor)
Flux 4's Same mods with monotherms = Rattled (had one injector not acting right - made rattle worse)
Marco's "supposed" 90's = very little rattle but still faint ( I say supposed because those SumB's made awesome power for 90's...Not much difference in my Flux 4's SOP meter)
Flux 4's back on with reworked / replaced part / blessed by the Pope injectors = More rattle than Marco's 90's... Seemed to get a little worse as they got broke in... But tollerable..
I'm Not getting in the fight about the "RATTLE vs correct parts" thing... I'm not the only one with this "rattle" throughout different mods and turbo configurations... Triton chased it for Years... Extrudes, Scheids, and Now Exergy stix.... All had rattle....
