We have a naturally aspirated performance calibration with a new K&N style flame arrestor which makes approx. 445hp, then we have a package setup with CMI exhaust, filter, performance cal that makes approx. 470 hp, then we have a new camshaft, cal, CMI and filter that makes 525hpThe SC'd engine comes with new injectors, the standard performance cals with and without exhaust utilize the stock injectors and stock pressuresDustin,Injectors are open quite a bit, but were increasing the engine efficiency with more spark and easier breathing. It does need additional fuel, but not a large amount. There is no question the 525 motor needs more, the stock injectors with stock fuel pressure cannot supply enough fuel consistenly or reliably.
I am a little confused on the injectors. Does the 525 kit need injectors or not? You said, "there is no question the 525 motor needs more..."
Thanks for the info on the new products. I am putting twin 496HOs in our new boat.
