Not Ranked
Hello Wayne:
I will be dyno running my FE 450 CID this fall after driving season ends in the Northwest. My current FE uses the Performer RPM intake, reworked. We are going to the dyno for the specific reason to test the Performer RPM against the Victor. During this test only the manifold and optimizing carb. changes will be made. One variable will exist: That being both manifolds will be port and plenum configured to optimize power in the RPM range the motor is designed to run in. So they will not, of course, be in a stock configuration. (But no one would run either manifold out of the box anyway.)
Since my Cobra is mostly street driven a broad power curve is more important the peak HP. (As it should be for anything other than a drag race specific engine.) This dyno test will be to determine the best overall power curve between 3000 & 6000 RPM with more focus on the torque numbers than HP. Some attention will paid to the 2000 to 3000 factor. As all street driven cars run here as well and only those fooling themselves do not consider this area.
Anyway, I would be happy to share the general results with you if you can wait this long. Probably done in October. Please let me know.
Oh, one other point. Even though I am running alumium heads I don't run over 9.5:1 and 150lbs ccp on pump gas. If you stay up with the direction the petroleum industry is going. 92 octane quality will be going down. I say this to point out that this lower number will negatively effect the single plane and could create the wrong conclusion if you plan to run a high compression. number.
Respectfully submitted.
