This will give you guys an idea of how the powerband is with the VR12Plus pipe. This testing was done with a well seasoned Orion .12 CRF engine (2 gal or so) and comparing it with Novarossi 2601 pipe w/ short conical manifold (a very popular combination lately)
As you can see the VR12Plus pipe is very close in power character, except it has a bit more power than the 2601 down low and seems to fill in a null spot in the power curve. However the 2601 does seem to rev out a little better on top rpm than the VR12Plus.
Overall this pipe is a very good performing product, and I ran it all weekend at the O'Donnell race at Revelation raceway.
By the way, thanks Ken for the replacement pipe!!!
Please note, that the results will differ slightly when using this pipe on other engines, however, this dyno graph should give you an idea of the general power curve that can be expected when using this pipe.
