How big did you guys go on the cam? You going to run dry or wet exhaust? Great numbers! Bet you are excited.

Perfect peak, then drops off.. beautiful ! Thats where a custom cam makes all the difference.
Wish I had some $$ left in the budget at the time of my engine fun for new cams from BOB but it was not to be.
Good luck with it!

All of the data is as accurate as it can be from the super flow. So yes peak ve is 106

It has wet exhaust, mixes just inside the transom.

How many hp is added by dynoing with the motor stripped down? As in no accessories and dyno headers vs. CMI or Stainless Marine exhaust. Awesome numbers for mild upgrades.

Less than 10 hp for accessories, dyno exhaust vs marine not sure. I'm welding a bung in the tails for my a/f meter today. May be able to get an idea from how far off the jetting is in the boat

We found from fully stripped with dyno headers to fully dressed pulling water thru seawater pump boat headers running boat cooling, wet exhast, flame arrester, alt, powerstering pump. It was just about 50 hp.

i think the wet exhaust vs dry is app 25 hp loss on a n/a engine.

You would be correct its not so much being wet as it is the up turn. Kills the flow of those nicely cnc ported heads!

Not sure of the number. ...but I am sure it won't be the same as the dyne (I'm also not going to reach 5900 RPM). All I care about is that it is #1: Reliable and #2: Relatively more power than their former life as HP500s.

More data (can't find the cam card!) attached.
