Looking to make a homemade powerpipe for my car, the measurement of the blower is 3.75" but I can't find a 4"-3.75" reducer elbow, only a 4"-3.5", I read some old threads that said it would work just want some info before I buy it.
what size powerpipe a 4"? I have an adapter reducer silcone ring inside the elbow connecting to the blower similar to what comes with an RAI intake for the Maf, this way the elbow fits more snug to the head unit
Yes my elbow is 4" on both sides and when I attached it to the head unit it was loose,you could buy a 3.75" straight coupler and cut it down to size to fit inside the elbow
^ It looks like it would work,will that ring be riding on the outside of the elbow?
