Thread: Pulley questions

ok i know this is probably a stupid question for most but i would rather ask . i think my stock pulley is a 3.8 and i am going down to a 3.5 do i would like to know 2 things if possible . first . will i need a smaller pulley belt ? second . what is the rough guess of what kind of power should be seen from drop pulley sizes ? i know there is a chart somewhere on here but i cant find it . thanks for the help fellas .

Going from a 3.8 to a 3.5 you will NOT need a smaller belt, I think that comes into play when you dip below a 3.4 I do believe. I think dropping to the 3.5 is like 2-4lbs of boost I think. I am not an expert on the boost to pulley size, I am sure there are others out there that can better answer that part of your question
