Brian Harden on hear has used this motor an Allison owner and dealer. He is going to report back with his findings compared to a XS on a fast hull soon I hope. He mentioned this in another thread on S&F. Not shure on what hull he was going to try it next? So Brian have you had the SHO to a good number yet? Not trying to put ya on the spot or anything just courioseLooked at em at the Bassmaster classic. They've got low water pick up. Light enough for the XB-21... Gotta say I am curious what one would do on the back of my boat. Any body wanna buy my XS for a fair price? I'll guinea pig this motor and play with the set up If I could afford it.
Wrong calibrations usually get expensive regardless, but it gets done with success regularly in this day and age... The LS based GM engines aren't an over bore-able engines and turbo set-ups are common and make HP with reckless abandon... With the modern knowledge of turbo systems and the advanced engine management at the disposal of a disposable income it can be done and of that I have zero doubt, it's a 4 stroke and that is a very credible buffer... One of these Guy's are gonna put one on a custom short mid with a light race cowl and drop about 50-75 lbs. with about 10 psi of turbo boost and were all gonna be talking about "the way it use to be" and squabbling for 2nd place...Although a turbo would be cool, it would also be very dangerous (expensive) with a non sleeved block. One wrong calibration,or get boost happy, and your gona pay big time...:gasp
Yamaha would be my next choise if/when my merc self-destructs.
Whipper, its going to be a couple more weeks. The boat is not ready yet. It will be a 721 Phoenix Bass Boat. I know its not an Allison, but its not a slug either. Should run a tad over 80 light and high 70s loaded. I already have the same boat with a 250 Pro XS that I will be able to do head to head testing with. I'll post up the results and hopefully some video as well!!!Brian Harden on hear has used this motor an Allison owner and dealer.

Its not really even going to take a turbo. This engine is WAAAAY under what its horsepower potential can be. Yamaha engineers told me that 400HP on this platform is easily done but in normal Yamaha fashion they detune it for the mass markets so it will run forever. I would think some good head work, custom ground cams, and a larger throttle body would easily get you to 350HP. Then you could always add a shot of the giggle juice just for fun. Everything inside the engine is forged so it will take it. This type of setup will be the future like it or not and they are only going to get lighter and higher in horsepower....
