CA Carb Modifications AR190

[qbndvl24]

All,

I have been browsing this site and have found alot of great topics, seems as everyone is here to help each other, which is great.

I recently purchased a 2020 Ar-190 and can't seem to get over 32/34 (CA Boat). I've seen many post saying low 40's, and out of state boats high 40's. I generally run the boat at the River (Havasu) or Castaic, Pyramid lakes

My question to increase top end and consistency, what can be added? Ribbon Delete, L13, K&N air filter? Who has done this? And what results have you seen.

Consistency will come from the L13 and Ribbon Delete. My boat runs the same wether I have no load or a heavy load. I boat at ~800ft asl and 42-43mph with other people on board is about "normal" for me. Getting to 38-39 isn't hard, the other 4mph require good water, favorable wind conditions, and long straight shot of course. I have a non-CA boat as well, so that might be part of it.

32/34mph seems a bit low. What kind of RPM are you turning at that speed? I get those speeds when I'm only spinning the engine around 6800-7000rpm. Some days I can cruise at 30mph at 6k, somedays it takes a bit more and I'm closer to 6400-6500rpm.

Not sure how else to help on a CA boat to be honest.

Whats the elevation at Havasu? Quick google shows 735ft asl, that sound right?
