I thought the 3" X-pipe sounded meaner and was faster, I really did! Until I got it to the track. After all it was larger than OEM with no cats to boot, that's why I spent the money. 
Oh, and I 'think' there are more AFE CAIs in the 9 second zone on here than Halltech's. Boostane (octane booster) from my testing is pretty good stuff too.
One last thing, weather always makes a difference. I had the 'same' 60' time slips with both throttle bodies to compare, but Hey I think we need other's examples too!

No Borla x-pipe. I 're-installed' the stock catted x-pipe after removing the Corsa. The OEM x-pipe returned the performance that I lost with the Corsa.

If an engine only demands 865CFM, what are the engine dynamics that allow an upstream intake solution that flows more CFM than demanded to increase power? Is it changing the VE?
Code:
CFM = CID x RPM x VE 427*7000*1.00 ~865

Regarding this forum's particular needs however (the supercharged LT4 engine), 865 CFM isn't even close to what this engine would ideally want for peak power potential but giving it what it really needs would never fly with an OEM tune....not by a long shot.

For the most part yes but these are general guidelines type of things and I see real world dyno results that suggest that isn't true (more CFM is almost always worth something). The easier you make it for the engine to grab that air to process with fuel the more power it makes.....clearly if your south of its requirements the gains are even larger from the upgrade.

The math would probably tell you that you need closer to 1200 CFM to properly feed that engine at 67 or 6800 RPM and it would probably make a few more ponies if you fed it even more (that's what I was getting at in my first post regarding this situation!). Positive displacement blowers love a reduction in the restriction of air in front of the blower
Cheers,
Tony
