reduction nozzle

[tbaer]

i just bought a jet dynamics reduction nozzle 82mm is this a good bore or should i bore it to 85mm. i have a stock pump with a 9/17 hooker 7mm back set and soon to have a freestyle pump cone. so what bore would be good?

go to 85... is that JD nozzle the one with the thick wall? you may be able to go bigger, but I am not sure if that is a good thing. there are mixed reviews on the pump cone.

the combo of the bored nozzle and stubby pump cone may cause cavitation, depending on your impeller and intake. i would go the 85mm and try the cone later if you feel like. if it dont work you can always resell.

i have a 9/15 impros hooker with a 7mm backset. i also have a worx 201 intake grate so should a go 85mm or keep it at 82mm. what is the stock reduction nozzle bore?

 

[AtomicPunk]

stock is around 82... bore that puppy to 85 and don't look back
I love my hooker!

so how do i go about boring it? should i just send it somewhere or do it myself?

have a machine shop do it (local or one that works on skis).. make sure it is taper bored.

well who does it on this site? should i still get a freestyle pump cone?
