Anyone running R&D pipe?

it works way better with it. you can set it up to have great bottom without water inj, but will sacrifice peak RPM. Why do alot of people on this site not want to run water inj?

wow
Im not running water injection and i am pulling 7900
have to prop up to stop it doing this
how much rpm are you guys getting
Its hitting so hard of the bottom it just launches big time
Im trying to find ways to soften it up so i can keep the thing on the track
Its lifting itself off the water mid corner when i pull on the power

Im thinking your talking about putting water in the stinger to create more back pressure up in the rpm range
 
You shouldn't be looking for any more peak RPM just a really good training regiment. Is it an 08 superjet? if so how much lead are you running? also what kind of peak speeds are you getting and with what pump?
 
I mean lead under the motor to make the ski weigh close to what a SXR or HS does. I was getting 63 out of my round nose with a 785 stock stroke, stock cyl, flat top with 27 lbs of lead under the motor. 140 14vein setback. for bigger motors the 142 or 144 is the way to go. was getting 7,780.
