does anyone know the different sizes between the stage 2 and 2.5 charger pulley sizes?

my kit currently has a 90mm pulley fitted and only made 220bhp on a rolling road it did have a few air leak issues on the inlet and the charger was wining a bit more than it should but thats all been sorted.

ive asked jamsport the difference and they did confirm the pulley is the only difference but didnt say sizes

 

hi mate its not just the pully its also the map. 90mm is for a 2.5 kit

the power seems low mite be wothe poping it in to me to have a look at some time

 

hi mate, im assuming by the user name you are jamie from jamsport?

i dont know what the power is now but it i thinks its a bit more than last time. thats by general feel but i could be wrong.

i have the copy cosworth inlet and charger kit with full milltek race exhaust (the larger version for charged/turbo)

what do you think i should roughly be running? and how much would it cost for you to look it over and see whats wrong?

 

wont charge you to look at it mate but if it needs a map then that will be 450 in the rolling road
