Default lbs/hr vs CC injectors

iv been building cars for years, most recently my 06 supercharged mustang, and planning this GSR turbo build had me wondering exactly whats different that allows me to make 334 RWHP out of 4.0 v6 with a 25lb injector which equals out to be like a 230ish CC injector and for a honda build larger is generally recomended for around the same performance. just a thought not trying to start some BS domestic vs import war, i dont care who makes it, once i work on it it becomes a jasan, not a honda, ford or w/e.

because there's 6 injectors vs 4. plus whatever base pressure you are using.

thats what i was figuring but i wasnt sure. thought the extra fuel might have been a compression need too. just curious to hear what other builders say

Like kyden said, the V6 is getting 50 lb/hr more fuel to make power with.

It all boils down to the BSFC, which for N/A engines is typically somwhere between .45 and .48.

lb/hr fuel / BSFC = HP

Doesn't matter if we're talking about 1 cylinder or 16.
