We have seen ZERO benefit on the Magnum 5.2L. The test you reference is
not helpful at all because it gives no information that can really be
used. "Hey, it worked on one engine" doesn't help when you don't know
what that engine was. Was it TBI? MPI? Carb? Chevy? Ford? Dodge?
Blown? Nitrous?
Again, people have tested the engine George has and found no benefit.
Until that "anonymous" engine in the magazine becomes at Magnum 5.2L,
the results have no meaning.
On a TBI engine, you may see benefit because the spacer gives the air
and fuel more time and volume in which to mix. Same for a carb. But on
an MPI engine, the injectors are right before the valve.
