Those are real world results of what that manifold can do. You're above 6000 all the time huh? So, you shift your car as follows: 1-2 9000 RPM 2-3 8700 RPM 3-4 7700 RPM Because that's the minimum RPM you're going to be making those shifts at to keep it above 6000. Either that or you're full of bullshit, again. Again, the short bus forum, his BS isn't put up with anywhere else. Shaun is the guy who couldn't make his own car run better with a Boss intake. Why would anyone listen to him?

For 1 most of use don't live at the track so we are looking for something easily tangible as a measure to go by if the investment in an expensive manifold is worth it or not.

2. Say all you want about dyno numbers yes, they don't equal a translation to track results but if you take a car already setup with a boss manifold rip that off on the same day with the same dyno in the same relative atmospheric conditions / temperatures and you see a consistent number difference with a new setup I think its pretty easy to say now you have some form of evidence to make a decision if it's worth it or not.

3. The Boss manifold has a consistent dyno proven history of the numbers falling hard under ~6500 rpms. That's been proven consistent on many comparisons on many dyno's on many cars. Obviously the results will vary but all are consistent with what to expect.

The guy on SVT Performance was essentially trying to show the comparison.

Unless your are making a serious amount of more power say like 30+ or more I think you can expect to see track results given you are a excellent consistent driver, which again most of us are not so its harder for us to use the track results as a medium for comparison.

I agree, you are 100% correct.

I understand your point to a degree. Yes a manifold will perform differently with the car not moving as opposed to being on a track with ambient air being forced to the induction system. However, a dyno, for the time being, is the best method of comparing the two parts.

Trying to compare that on a track is going to be unimaginably more difficult. I would say do this same dyno, then on the same day put the car with both intakes on an automatic(to reduce driver error) and see what happens.

+1! This guy understand the point of this thread.
