All my testing has been with new and old pipe back to back.
But keep in mind most that testing is on a TNT build motor.
In my Pv. 84mm X 6mm stroker , pulls harder and revs much harder with mod pipe.
59.7mph to 62.8mph. No other changes
With spec chamber 60.8mph and stronger pull off the bottom less punchy
Free ride I feel we need hard quick pull to get the boat to rotate in air for clean back flip. I believe the old pipe was to punchy without enough pull through.
Old design was tough to get good rpm without a lot of water routing tricks.
The new one doesn't have to be real hot to rev decent.
It's just a better design for the bigger motors.
The new pipe smallest diameter is 53mm.
Old pipe was 48mm. If you opened up head pipe to 51 in B headpipe it ran much better. And if you go to 52 or bigger it ran real good but was pipes break.
So you start at 53 and can go to 55mm.
But the new pipe matched with the water box is an amazing improvement.
My non PV 5mm 82mm bore motor is faster then my 84x6mm Pv motor if I run old pipe on big motor and new pipe water box on smaller non Pv motor.
The other people who have gotten early pre pro pipes also saw big improvements over old pipe.
I will be at havasu with some pipes and water boxes if anyone wants to have a look.
Or if you have RD man I will let you test one of the chambers.
i assume the answer would be no lol but have to try. i am nowhere near the level to purchase a 1000$ pipe
