Hello here my engine config:
-wiseco 8:1 pistons
-eagle conrod
-kingracing bearing
-stroke 84 bore 84 (2800 cc)
-megasquirt 2 pnp k-data
-gt35 turbo non official (0.68 exhaust ar) t4 flange with obx t4 exhaust collector
-525 delphi injectors
-76 mm downpipe, 70 mm exhaust
now at 1.35 bar i dynoed before 530 hp ..and now car went down to 440 450 hp, and i do not know why.
i run 10w60 valvoline oil, but i listen my engine noising and ticking , usual hydraulic lifter noise.
Now the main question:
Can hydraulic lifter affect engine power, or the make only noise without stealing power to engine?
thanks
