I vowed to not waste my time on another Bravo system and purchased a 700sci / NXT#6 setup. The good news for those of you who have big power with Bravo's is that the NXT transom assembly matches up to the Bravo bolt pattern. The transmission sits inside the extension box, so you don't need to relocate your engines. bolt up the #6's and breaking drives is a thing of the past.

What trans does the NXT use? I would assume it's like the NXT and completely overengineered for its power rating, but would the trans hold 800-900hp with a big load?

So you mean your engines are in the exact same location as when you ran through the Bravos?

I wanted to have Bill rig the Ilmor's in my 38 Fountain but Ilmor wanted it sent to their guy. Other than minor rountine maintenence I have yet to need anything major done to my Fountain so I just take it to the local dealers down on Cumberland rather than drag it back to Indy. So other than getting my props thru him and his giving me advice he is yet to turn a wrench on my boat.

From the times I've spoken to him and from what other people have said, he seems to really know the Imco product and and how to make it reliable and fast on Fountains.
Thank you....I am towing boat up to Indy this weekend!!!!!!!!!!

I don't know if the props caused this or bad gears. Several of the teeth were gone and it looks like one of the teeth may have been cracked for a while. It was not shiny like the rest of the broken parts. Good luck with your change.
I am interested in your problems with Whipple. Was it the blowers or the install. That was my winter project to install on my 525's. I have an excellent mechanic who has done several whipple installs on other engines, so I am not worried about the installation.
It was both....I could go into a doctorial thesus on the problems we had with this "Bolt On" application but it would only elevate my blood pressure and probably scare you to death. The "kit" is not complete in any way. Some major retrofitting needs to be done in order for it to work properly. The engines are awesome now (knock on wood)...but if given the chance to do it all over again I WOULD NOT do it again. I sure hope you have better luck than I did...Ill let you guys know how the SCX's work.

Mine boat was built from the factory as a 700sci / #6 boat, however that is the information I received the HiPerf mechanic at the dealership.
