04 rxp porpoising problem
ok guys i have a 04 rxp stage 2+ with riva block off plates (just the cheap ones) the problem is that at about 75 she starts to porpoise real bad what can i do to help? i know some say to install the pro opas block off's but i have read some other posts saying they don't even touch the water at that speed. what do you think?
also i am running a wedge should i take it out?
here are my ski's mods:
fizzle intercooler and 4" air (with afr ect.)
cut and smoothed fins in pump shoe
reverse gate trimmed
holes in ride plate filled

get RE block offs or Riva pro series opas block offs... REs are hard to come buy and new are almost 400 to your door in most cases

Your problem is that you have removed the opas and just put covers. Now you have a void that can create your issue at 75+.
The wedge is only going to make it worse with that setup.
I say run opas or install some block offs. I never have liked the ride with just the covers..

ok so first thing i should do is remove the wedge then look for some pro block offs.
is there anyone making homemade versions? these things seem to be quite overpriced.
