Pro charger pulleys

What’s the largest and smallest pulley for a d1x with an 8.25 lower. Can be ran.

3.7 more than likely.

could try squeeking by with a 3.55, but you will just be blowing hot air at that point.

this is assuming stock cam

Full motor built just trying to see what I can do before tuning and have some adjustments. I think 3.55 would over spin the unit. But also looking to run lower boost for other events I do.

3.55 would overspin it by a few thousand rpms, but some people go as far as 10% over the rater max impeller speed.
