Driving mostly from 8000 to 10000 feet in elevation I am looking to get as much air into the engine as I can. I am looking for easy bolt on adds for some power, so no rebuilding of the motor, which is beyond me. I read about these manifolds on a hot rod site, so they are oriented to older cars.
We have used offenhauser intakes, they work well. However I don't think just that alone will get you what you want. That along with some other improvements may get you just what you want. You can check out the one on the services pages on our website; we were able to get around 40 additional horsepower set up that way. We were after additional torque mainly, it worked out great and we got all the extra we expected.
