New video from X Power Drive Low Boost
 
So you don't hear this very often, but instead of throwing more and more hp at it we are testing effeciency, and how little it takes to make it go fast. We are testing a new X Dimension vs prop blade diameter/rake and it seems to be working. This motor made 1285 hp on 8.8 lbs of boost and now we have turned it down to 4.4. I don't have the dyno numbers but my guess would be something between 30 to 40 hp per lb of boost. That represents between 264 to 352 hp loss. We were still able to get 166.7 mph on a little run at Lake Elsinore and it was still slowly climbing. Thats not bad if you do the math. Check out the video and lets's get ready for summer!!

Nice. What way are you going with depth, diameter, and rake?

Wow

That is damn impressive. Slap on a set of bravos/Imcos and see what it does for a true back to back (if you can get them to stay together that is).:eekdrop:

I would love to put on a set of bravos to see what it would do back to back. We have always done it the other way, removing the bravo and replacing it with the X Power, and we have always seen gains. Does anybody want to loan me a set of bravos to do the test, they might need slight repairs when were done with the test LOL.

I will loan you my Bravos if you will loan me the X Drives.. sure no problem!!

Your 32 has to be the most impressive Spectre ever built, not just because of the speed, but also because of the attention to detail... fantastic job Bill!

Thanks that's really nice of you to say. It's a labor of love, and I live to be on the water listening to those blowers behind me there is nothing like it.
