Don't hold back, share the knowledge...
Sorry I didn’t catch this. On baby motors (i.e. 3208, 3208T, 3116 etc…), marine nozzles without more fuel will unload faster, obviously, but in doing so timing follows exponentially. More timing is not so much a bad thing, but look what you’re working with in the first place. Backing off the timing if you both crank it to max and put bigger squirters in will be in order. She’ll be way hot if not. So, the bigger the hole, the faster the dump, the more advance to timing, the more heat, on and on. Rule of thumb is bigger injectors when you run out of fuel capabilities at the pump. So, crank the hell out of it. If it’s not enough, then injectors (or nozzles), but keep it cool.
Bigger injectors on big bores lead to many questions. First off, is a better cam a better choice at 1/3 the cost? Second, is it a late enough model that compression is so hi you get fire chase just from injectors? Will you get the same delivery by cranking T-pump pressure for 10% the cost? 957’s to 958’s is the same as 65psi transfer pump pressure bumped to 120psi, however it’s done (shimmed plunger, secondary feed, etc...)
The main thing to remember is the bigger the delivery, the more the timing advances mechanically, even on an electronic motor. This is good to a certain point. If compression is way hi and you have twins, a cam is way better, then play away with injectors, as long as YOU HAVE ALL GAUGES. I could go on but y’all get the jist of it…T
