Injectors For 408w

Unread postby chiphaby » Mon May 18, 2020 10:23 am

I just finished building my 408w and I am looking for advise on what might be a good injector that has data for tuning. I currently have FRPP EV6 30 lbs. which will not support the horsepower of the 408w. It was suggested that I turn up the pressure on the 30 lb injectors because the EV6 has better atomization than the old EV1s. I think I would feel more comfortable with say a 42 lb. EV1 injector (with data) running at 39 lbs. than a 30 at 60 psi. Thoughts?

the 30s will be fine would be best to run 65psi of base fuel pressure

other than that I never recommend anything less than the siemens deka 80s from chris at poweraddersolutions

How do I figure the injector HS/LS/BP and offsets at 65 psi? I see you have data for them (BB302) at 55 psi under reference.

Would the high and low slopes be: (original flow rate) x (new pressure / old pressure) and the break point and offsets stay the same?

I'll add the bb302 data at 65psi base to the injector reference page

are you sure you have bb302s ?

They are the red EV6 (slim) injectors with 4 holes in the bottom. I was under the impression that the "fat" injectors were the B302 and the BB302 were the better, slim 30 lb with the 4 holes (better spray pattern).
