Smile Increasing max rpm for NA d24 84 model engine.
I finally got a tach and calibrated it and the max rpm seems to be 4800 rpm. Max power is 82 hp at 4800 rpm as well so would increasing the rpm along with fueling increase hp?

I have seen a video of D24TIC going max speed at 5500 rpm.

This would have the benefit of being able to go faster on a lower gear and possibly even accelerate faster?

Can the naturally aspirated engine valve train handle this and how would I increase the pumps rpm limit?
