Anyone got some dyno sheets of the JG/Edlebrock Victor X Manifold increase over stock? especially stock gsr manifold.

Just a stright up comparison of that vs stock manifold on the same car, same setting/boost.

I am just wondering because in a magizine ad they claimed a large power increase on high boost.

Also anyone dyno the Skunk2 Turbo cams vs stock?

 

I took would to see this..

 

honestly, a back to back test such as this one would be meaningless. Obviously, it'll flow more. So, it flows more, and leans out the motor most likely, and it will make either the same or less power as a result, assuming previously the motor was tuned properly. There are too many variables in a piece going into a high performance setup like this that makes a back to back dyno test impossible to do properly and net meaningful data from.
