BIGGER Crossover tubes
 

Ok sounds good but no jetski then lol

They add no hp not even on ppump motors

Until the tubes make some major power gains stick with the stock ones.

real world examples I made 683hp stock lines and tubes a buddies ppump 24v made 843 on stock tubes and larger tubes. it's just wasted money

Dont waste money on newer cross tubes, take ur tube off and look oh the inside of it. You will see a restrictor valve that runs towards the nozzel head of the tube. Drill press that bitch till it breaks, and pull it out.... there u have unrestricted tubes.

Ya that would be great but what size drill bit would be used for that.

I believe it a 3/16 but just take the smallest drill bit u have and see if it fits in the cross tube without hitting the walls. Best if used on a drill press
