Oh wait, that's right, the tornado doesn't work. It needs that certain mojo that a spacer has.



Build a heat shield, clean the TB, optimize the TB, clean the UIM and LIM. All these are proven performance enhncers that are inexpensive. Throttle body spacers fix a non-existent problem, imho.




The first part of your post means what? That you're mechanical insight is to compare a useless product to a product that has been proven for how many years? Let's get out of the grey area and into the now, thanks.

The last part of your post i agree with and i believe a tb spacer will do nothing. But people who do modify thier cars, don't believe in the old theory, "if it aint broke, don't fix it." Obviously, you just don't get it. When these spacers are made and takin to the dyno and have some #'s, then i feel it will be appropriate for you to make an opinion such as yours. Until then, please don't talk out your ass. Thanks.



I agree that a UIM/LIM spacer MAY help with heat at the expense of the port tuning. You can guess if it helps or hurts. if you get 5 hp on top, and lose 5 hp on the bottom, you performance may be lower even if your max hp is more. If you are looking for Max HP rather than fastest performance, you are on the right track.

When you have dyno #'s to show a TB spacer works, I'll admit I am wrong. I have no mechanical insight other then a decade of experience as a Mechanic, and nearly 2 decades as a mechanical engineer, and nearly 5 decades of life experience. When you have been around awhile, sometimes you learn something (sometimes not). Spacers on carbureted cars were the rage in the 1960's. The decrease in carb bowl heating usually helped, though sometimes didn't, since some applications the carb froze up (air, expanding into the manifold, actually has a refrigeration effect) and decreased performance as they needed some heat. In other applications, the intake manifold was less than optimum. The spacers added some distance before the incoming fuel/air charge has to make a 90 degree turn at the bottom of the intake. This added a little performance to the intake system. But not all intakes, just some. So what were you doing in the 1960's that you missed the great carburetor spacer fad? I thought everyone knew about them! What's that saying? "Those who ignore the past are doomed to repeat it."

It is unlikely that the small extra distance on a Throttle Body will change anything measurable in performance. Comparing the TB spacer to the tornado is a fair comparison in my mind. I seen lots of posts claiming increased HP and mileage from them. Yet all they really do is increase restriction in the intake. The spacer does have an advantage over the Tornado in that it probably won't decrease performance. Don't you think F1, indy cars, nascar cars would be using spacers and tornados if they really increased performance? Nascar uses spacers called restrictor plates, but they don't increase performance (sarcastic joke, the restrictor is not quite the same). If 3/8" space get more performance, why didn't ford make the space from the throttle body to the manifold bigger on the SVT and take advantage of the extra 5hp? Honda gets 240HP from a 2L 4 without the spacers. Maybe you should call Honda and tell them they missed 5hp.

Post the dyno chart (just stock, and then just the spacer). I bet there isn't a significant difference in the 2 curves other than normal variation from one run to another. In fact, I bet anyone here can tell you of a 5 hp difference from one run to another with the same car and configuration. So how would you prove it's the spacer anyway?

But since this is the internet, you can safely ignore me anyway, but I felt an urge to respond. It is always appropriate for someone to respond to a post. You posted it for comments, I commented. You don't like the comment, ignore it. It isn't a bad thing you are doing, in fact, it is probably a good learning experience. Oh, make sure the spacer is yellow, if you know what I mean Don't forget the IAT resistor mod either.

Since you really don't know me, but felt free to comment on what you feel is my behaviour in how/where I talk from and how i have the "if it ain't broke, don't fix it" attitude, I'll feel free to comment on your position in life. May you always be as happy as you are now. You must be extremely happy, after all, ignorance is bliss, isn't it?

Merry Christmas, Happy New Year.
