Water Thunder Performance

Well it looks like we found out how much nitrous a RHS block can handle. By the looks of all the cracks I would say about a 100 HP less then what we run. All the cracks follow an original cast line, casting lines are stress risers. So it looks like the next BIG NITROUS RHS motor we build were going to have to polish all of the casting lines out of it.

Are these block stress relieved after casting?
What about an artificial aging process or an uphill quench process to help block strength.

If you look closer you will see the video quality on this one is better since it was done with a GoPro Hero 3+ Black set to 1080p @ 60 fps was able to keep up with the blades vs the other one done on a Note 3 cell phone, so the blades jump around and looks more like a 6 blade since it can't keep up with the speed. Both were done after the motor was tuned and ready to ship. Can't get a built up EFI motor to idle at 500 rpms, I've tried.

Tony that purple boat was the second boat I ever built. 15x8 deckover with poly and 550hp Levitator LSA, 2.7 Ballistic and 4-blade 79" Whirlwind turning it 5400rpm. It's a 70mph boat tops, no where near as fast as Gregg Wooters boat. If we were to run that race all over again today, Gregg's boat would make that purple boat look even worse. Motor and hull upgrades on his end. I wouldn't take that race today

Yessir. Technically mine was built and it went to Nebraska on a hammant....But it would have sat since I was gone so Dave went ahead and sold it and started building me another. Then we got pregnant and I had to grow up some and Dave and I came to an agreement on it and here we are lol.

Tony I can promise you this, it didn't grenade and didn't even come close. The blower motor wore out the valve guides on #2 and #4 cylinders and dropped valve. No real idea why, just did. Although methanol can be hell on valve guides. Man it's so nice to have someone like you know my business so well...it's almost like you work for me LOL
