creating 160 HP - stock injector over 100%
Things are progressing nicely at this stage of the project.
I am up to 38-40 inches of manifold pressure with my stock injectors at or over 100% duty cycle. These are 185cc injectors which I have read will handle 160 HP at 100% duty cycle. This is a very rough estimate and could vary by probably 15% so take this with that in mind.
Another perspective is that this engine in stock form is 135HP when at 30" of MAP. So this also stands to reason that at 40" you would see about 160HP. Just some rough numbers, nothing to bet the farm on.
Thankfully the SDSEFI controller shows the injector duty in the display - which is very helpful.
Fortunately there are a lot of the larger 2.0L and 2.4L Honda 4 cyl engines that have 310cc and 410cc injectors. I have a new set on order. Ill post more when I load the engine up to 40+MAP using the new injectors. I am hoping for 80% duty cycle at 45" at 5000 RPM. This is roughly 5lbs of boost which is just find by me.
