there are a few ....big chargers...and lots of ride plate work..to have seen 82 ish on stock ecu..but lots of work to get there ..if they had an ecu they would be 86 above 80 the hull becomes a huge wall

80+ on stock ECU has been done quite a few times ... What I would do would be to start with all the usual stuff, very good air intake, intake grate, external IC, 15/20 Solas, X charger or better, Riva Ride plate & heat exchanger setup, and then do all the little stuff and fine tuning. Many of us have run 77mph with that setup, with less boost and no Riva ride plate ... a little more boost with an X charger or upgraded X charger, plus the Riva ride plate should get to 80 mph, BUT it does take fine tuning of the impeller/rpms, clean up of the bottom, etc.

For those of you wanting 80+ on stock ecu, It's not that hard to do anymore. Watch the beginning of this vid and check out the slow mo in the beginning. You will see what an 83+ mph stock ecu boat rides like with 245lbs sitting on the seat. Now imagine what it rides like in superman position. 80+ is easy on stock ecu with the right set-up for top speed. Gotta get the hull out of the water. No need for porting or valve train upgrades.
The rest of the vid isn't bad either.

but everyone needs to realise lots of hull and ride plate work went into it ..they arnt going to just bolt some stuff on and it be there ...the rxp hull hits a wall at 80...75 77 is easy 80+ gets difficult..
you are running a big et charger. arent you
i have seen your ski more out of the water than that....it is funny you can watch him hit the gas when you came buy him and you still went buy at a clip ......and who is the dork on the yellow and black rxp in the hat....LOL
