....to me it doesn't look like enough difference to worry about at the 450hp level.

In the article you linked to , if you only look at the peaks, they seem similar. But look at the numbers at 3000 rpm: 381 ft-lbs for the SD, 408 for the RPM. In a car with a low stall converter,I would expect the RPM to have noticably better low end than the SD. Oops, I guess I should read all the posts, not just the last few. I don't think you can directly compare the B versions of those intakes to the RB versions. I have heard more than once that the RB SD is better than the B. I suspect that the RB version is a better low end torque producer due to the slightly longer runners . Anyway.... after reading the OPs combo, I would bet that on the strip, the SD and the RPM would probably E.T. very close to each other. On the street, when you don't feel like downshifting, the RPM may be a little more responsive.
