FORD racing boost gauge question

it "should" measure boost from any sort of super or turbo charger. you want to hook it up anywhere downstream from the supercharger. typically a boost controller would be the best place to pipe one in.
 
a boost gauge is just a vac gauge that reads pressure also. if you put it on a N/A engine, it will read vac only and never read boost. it will read any blower. and its just a small plastic line, just plumb it right to the intake manifold. an easy way to do it is to "T" into an existing line.
