The 200's use LESS high pressure oil than a set of Baby Swamps, less oil than stock AB, or stock AD injectors...so even if your HPOil pump is "weak"...by simply installing an injector that uses LESS oil than stock injs...your pump will be able to support nearly any ICP pressure requested by your tuning.
I have run nearly every single injector that we have ever, or currently do offer...and both of my current 7.3L's are running our 200cc hybrids. Stock HPOP, stock fuel system...and one truck isn't even running studs...and hasn't for years...with no plans to.
I will say that IF you are going to be using any injector in a competitive nature (dragstrip, sledpull, or extended harrrrd runs on the street/interstate)...that you would be well advised to install studs & springs...
but if you're going to drive it 'normally' for 90%+ of the time, and only sparingly beat the snot out of it...then running the 200s w/o studs/springs is not reckless.
we sell dozens of the 200/30s each month, and (with our tuning) can only recall one person having any type of HG problem..and that was on a fresh build with an unseated headgasket.
In my opinion the 80% nozzle is a smokey pile...the 100% nozzle is not much better for the increase in power...so we generally recommend the 30% nozzle or the 200% nozzle...which can be just as clean as stock with the right tuning.
The entire reason to install a larger nozzle on any injector is to be able to deliver a significant volume of fuel AT A HIGH ENGINE RPM....
the 200/30% injectors can empty the full shot up to 3700rpm..and while they will still function at 5000rpm...the volume of injected fuel would be cut back to about 150cc's.
So, unless you are planning on running the engine above 3700rpm regularly..at full power..the 30% nozzle will keep nearly STOCK atomization (low low smoke), exceptional fuel efficiency, and will run damn good against other/newer 'tuned' trucks on the road.
We've done our 200cc hybrids with our 200% nozzle on quite a lot of trucks...(one of mine as well)..and that combination (200cc w/ 200% nozzle) has been a consistent 550rwhp...on a bone stock HPOP.
the 200cc hybrid alleviates ANY concern with regard to the HPOil system..since that injector size physically CAN'T use more oil than all but the absolute weakest HPOP in the universe could support.
It's just silly in my opinion to build an injector with a larger nozzle than the expected engine rpm dictates...
the loss of atomization isn't worth it for 99% of the street trucks.
