I run 900 HP run mine with a 15.25X29P Maximus, and it runs perfectly, it just strong as an NXT #6.

Strong as an NXT? I find that hard to believe with NXT shafts and gears being larger. Definitely not as strong as a #6. NXT Transmission is the weak part of a NXT setup.

Mine is the XV/Bravo IX (Stage IV) built and assembled by Powequest R&D with AADS back in 2004 before XRs were available to the public, the XV Extended Drive is basically indestructed for speed and power, the transmission will hold any shift and hold any power with my whipple 525 EFI (10 PSI) and the Bravo IX is a completely 1.25" cynogenic drive with the internal frozen at over 150 degrees below zero, this will double the tinsel strength of reciprocating parts in the drive, and a Maximus is a big prop to boot. 100 MPH at 6000 RPM. X Mod*Full Tower, Mercury Steel Ribbed Top Cap, Chromoly Spanner Nut & Seal Retainer, XR Custom Gear Set, XR Custom Shower Cooler, AADS high tensile strength alloy clutch shaft, Sportmaster Custom Lower Case, and REM Polish Selected Components. Phase Four drives receive the AADS high tensile strength alloy clutch shaft and drive shaft with 1.25 prop shaft with billet carrier assembly and coupler *Critical and selected components are also Cryogenically treated and REM polished for maximum performance.

Looks like I should sell my teague 980s and #6s and go with a 900hp 525s with bravos, sounds like a much better package. Sounds bullet proof.

Hey mongoose can we see some pictures of this XV/ Bravo1X set up and your 100 mph Powerquest.

before xr's were available to the public??? WTF are you smoking, my boat is a 2000 and came with xr's stock, secondly the pic on your fb page if that is your boat is an imco on a box, with an SC lower...

Lol, that was the first thing I noticed.

He may want to look into a psychiatrist if he thinks any XR can hold a candle to a #6.... preferably one with a star rating above a 2....
