Congrats Jason and Dennis can't believe how far the boat has come from the first time we ran it here in CA. You and your dad have done something I don't believe that anyone understands. I was floored by that last run it was amazing !!!!!!!!!!!!!!!!!

Let me stress that I'm in no way shape or form taking away what they have accomplished. But after so many hull modifications, done , by I assume themselves, is the boat really still a " black thunder" ? They should seriously consider building there own boats. It very well is obvious it takes a lot more than just horse power to achieve those insane numbers. Black Thunder " parvey edition"!!

Perhaps BTs have a really efficient hull design. We just don't know because none have been radically like this one. Most were saddled with bravos and were quite heavy 46s.

Thanks again everyone for the kind words! I'm still digging up some photo's and going through on-board video's and hope to have them posted this week.
We were thoroughly pleased with the 165mph, and we were not expecting that at all. As many of you saw, our first run did not go as planned. As a result, we decided to be conservative and slowly ramp up our runs while getting a feel for the boat. 2nd run was 142, 3rd run was 151, 4th run was 159, with a final 5th run of 165mph.
After reading through this thread, I want to touch on a few things that have been brought up:
1. Shootout vs Kilo: As Doc J said, a kilo and a shootout are two different animals. They both have their advantages and disadvantages. I will say, what Forehand did in Sgro's 180 kilo boat is nothing short of amazing. I do not think we will attempt this feat.
2. Hull Info: The Black Thunder was an excellent boat to start with. We use the same layup schedule that any other Black Thunder is built with (Baltek AL600 is used to core the entire boat with bi- and tri- directional glass). We have modified some items on the pad, a few lifting strakes, and the transom notch. The step placement & shape, as well as the deadrise remain the same. Our boat ran a best of 99mph with NA 750's (this is back when prop and skeg technology was not as good either). I cannot guarantee this, but I think the 43GT with modern prop and drive technology, along with a few tweaks would be capable of 100mph. FYI, Black Thunder has a bare 43 GT hull sitting in their shop that is setup for 700's and 6's.
3. Powertrain: The boat currently has motors that we built with the help of a couple engine machine shops local to MN (Wheeler Racing and R&R Performance). The motors are 572's with stock Dart Pro 2 Heads. The induction package consists of Holley EFI with PSI 206B Screw Compressors, as well as Intercoolers that we built. Putting the power to the water, we have #6 drives worked over by Matt @ TNT with Velvet Drive Transmissions provided by Bob Teague. We would also like to give a shout-out to Ekvall Engineering for their machining/milling expertise with various projects of ours.
All in all, we had a great time at the shootout this year. Aside from the racing, it was so great to catch up with so many friends at the different parties, and on the docks as well. Until next year!
