So haveing 4 gas engines in the 8-900hp range is considered more reliable than 2 race gas engines in the 1700 to 1800 range? You would think haveing twice as many moving parts would equal things out as far as stuff to go wrong and break. But wow.....i cant wait to hear this thing scream by.

1700hp at 6000rpm's is by far better, than running it up to 7600rpm's and not having to run race gas. That 1700 was on 93 oct.

This should be a reliable very fast pleasure boat. Congratulations!!!
Here is the website with the pictures.

The site says the V16 only makes 1500hp so I doubt the boat will run 200 because of the weight and HP penalties vs the 500lb 1850hp T53-703s.

It's a 558/800hp motor so that may be the top HP figure Eickert can get out of that size block. If he used the new Dart 765ci race block he could get at least 900hp, probly 1000. Now the numbers look a LOT better don't they?

1700 hp pull on the dyno

Will this setup have 4 exhaust pipes coming out of the back of the boat?

those look like carbs in the vid. Other pics of the V-16 have the "manifold" on top of the tunnel ram, and another pic of the motors in the boat shows them having velocity stacks..... just noticing that's all.
