Good question, and the answer is a resounding no unfortunately. To see gains anywhere near even the 5-10hp range, you would probably need a throttlebody the size of the actual car. And no, not kidding, here is a very good thread explaining why they have no actual benefit https://mustangforums.com/forum/2005...r-problem.html

The second poster on that page explains it better than I ever could, but the summary is that the little thin spacer is not going to change air flow enough to even matter, and it's only creating more seams/joints where you could end up with intake leaks.

As far as dyno tests, you get into a lot of "he said/she said" where there are conflicting interests. A company that makes/sells these spacers isn't exactly going to want to show that their product is an expensive and attractively painted paperweight, and owners who have done dyno runs have a lot of variable factors (mods, ambient temps., type of dyno) and 5-6 HP isn't going to be accounted for very accurately as that is WELL within the error range of a dyno.

And that TB is only going to give you costly trouble in the future, if you think about it for a second- that TB motor is designed to manipulate a certain size butterfly valve, when you just slap on a new TB ***** nilly, you are asking that small motor to provide more power than it has to operate the larger TB, and chances are you will burn it out.

That was a great reference. I wish I had read that a couple of weeks ago before I bought the TB.


That was my observation as well. I was hoping that in asking there might have been some article out there that systematically tested this out. I wish I had access to a dyno because I would take the weekend and test it out.

If it's about turbulence, then why not use AirRaid EconoAid (http://www.airaid.com/econoaid.aspx)? Are you ware of anybody testing this out? Wouldn't the PowerAid help with turbulence.
