I would say that they are knocking on 1100 hp with the boost at 11 psi. They made 1020 hp with just less than 9 psi, so another 2+ psi should be worth approx. 75 hp or so.

Right at 6000 rpm. Boost is a little higher with those 6 blade cleavers since they bite really hard. Ended up with 11 psi at 6000. It's fine on 93 but I would like to check it out with 91 before I declare it safe. I think it would be OK, but it is pushing the limits of the octane a little. I can always drop an 1/8" in pulley and it should be fine with 91 octane. As it sits, it didn't even think about hitting the knock sensor. It never even breathed on it.

Congratulations Eric! I know how it feels to bleed money into a boat and believe in people that continuously let you down.
So what did the water pressure problem turn out to be and the solution? I know early on in this thread there was praise for the Fountain pick-ups. I am needing to update mine when I decide to pull the trigger. I was looking at Teague and Stainless options.
What was the final verdict on the reason the Crockett motors wouldn't perform/last...fuel delivery?

As far as the previous engines failing, well, I'll leave that one alone. Eric and Gavin know all the details of what was found when we took them down. Every builder has their own way of doing things. There is ALMOST always more than one way to get something done. However, there are some things that are just wrong and won't work no matter what. There was some of each going on. I won't get into details because it's not my style. If Eric or Gavin would like to then they have the right. That's up to them.

Ya, 11psi on 91 might just be pushing the envelope a tiny little bit on a hot day and a long run. All in all, sounds like a real nice package you built.
Congrats Eric, you're a boater again.
