Quick help with nrg rollers

What 'should' they be on a NRG with ZX? Everythings pretty good apart from topend and uphil compared to me,so im guna wack my old belt in his and maybe chuck some diff rollers in? But instead of chopping & changing anybody got any ideas? THINK he has 8odd in there atm? Thankyou.

 

well need to be well lighter than 8.

try something like 6's ?

 

I ran 5's in mine with a tt pipe last year, it pulled fine

 

5 abit light for stock barrel

 

Had 3 8.4s in and 3 5.5s. Then we tried 3 5.7s and 3 8.1s and it was slower,not sure if it was too revvy or not was hard to tell,then we made 7.7 mixed and still wasnt as quick so we went back to the original weight and all was good again,so must of been set up ok before,chucked in my old belt and variator and its a lot smoother and he seems to think quicker. So cheers boys.

 

I found fitting a torque spring helped
