Well, do I think it works and makes a difference, yes! Do I think it makes a big difference, no and I didn't expect it to. I think it's made a difference in throttle response, acceleration and mpg. My truck use to do 0-60 on the old stop watch in the low 6.4 range consistently, after the HPT install, I can get into the mid to high 6.3 range consistently. So, it's made a difference of almost .1 in my 0-60 times. My 40-60 passing times use to be in the high 3.3 range, now they're in the low 3.3 range. Mid range power feels the most improved. My driving pattern is usually about 75% city and 25% freeway, my truck has always gotten 15-15.2 in the warmer months and 14-14.2 in the colder months as far as mpg. My last two fill ups after installed the electric fans were 14.6 & 14.8 mpg. This tank was 15.02 after the HPT installation. It's not much of a gain, but it is a gain. As far the whistle, it does it but it's faint and only about 20% of the time. If I crack or roll the window down or turn the radio on, I can't hear it at all. Now, is it worth $100? That's up to you! I got it off of Ebay new for $75, for that price, I like! I've spent alot more money on a mod and actually lost mileage and performance (mufflers and intakes to be specific).
As we all know, it seems like the exact same trucks will respond differently to a mod for some reason. All this is just my opinion of the HPT on MY truck.

Sorry, but those things are one of the biggest hoaxes on the market. Right up there with the "Tornado Intake" gizmo. Air velocity into an engine is subsonic speed and the very short longitudinal area that the flow of air passes over those "swirls" isn't going to do much. Once it gets into the intake manifold it gets all bent and redirected anyways when going into the runners. If that swirl was followed by a straight length of tubing and nothing else, then it might possibly affect the boundary layers within the flow. But, it has an intake behind it. Whatever happens before the intake manifold in flow form isn't going to affect it once it hits a runner and begins to accelerate into the engine. This part doesn't increase flow (like less restrictive tubing intakes, filters, etc...) so it isn't helping.

Sorry, but I hate hoax crap mods. I specialized in compressible fluid flow dynamics for my degree, so I'm pretty confident in my flow characteristics background.

also, "swirling" affects tend to help atomizing fuel in an intake system. But we do not run carbs, and EFI setups don't count here.

Tony, admit it. You didn't get into the tens until you bought two of the "power tower" and installed them back to back. <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

All I know is that for the past 3 months my trucks mpg has been in the 14's, after the HPT install, I got 15. It may be a fluke, but I check my mpg ever tank and I haven't gotten 15 mpg since September. As I stated, all of the gains are small but I feel they are there. I have installed a number of mods that I don't think do a thing and have taken them back off, to each his own.

I agree with Tony 100%. I had one for about 6 months and saw no difference and then removed it, still no difference. The only thing that I noticed when I had a spacer on was that my TB didn't gum up like it does normally.

Also, and I'm not picking on anybody but I don't rate HP increases by increases in mpg, they're two totally different things. Maybe your not going for power though just mileage? I can take the same route for a month and record everything and have different mpg numbers every time. There are too many other factors. Please don't take this as a flame. I think it's good to keep an eye on mileage, I just dont use it as the be all end all in evaluating a product.

Hey Jim, its your $75 to waste.

But, please explain how gas mileage is changed if this spacer does not increase or decrease the airflow into the engine, and does not reprogram the fuel curves.

Basically, all you did was make your intake tract what, an inch longer than stock? So, by this same "theory" you should be able to gain 1 mpg for each inch in intake tract you add? Uses the same logic...

Does not increase airflow = same air monitored through the MAF. Does not alter fuel consumption, this is controlled by the computer. Air/Fuel ratio is controlled by reading the O2 sensors, also a computer function.

Adding a 1" spacer isn't going to do a thing. Ever heard of those prescription drugs that some doctors prescribe to patients that are convinced they have an illness even though they have no symptoms? Just sugar pills, but the patients think they are real medicine and start to feel better. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

everyone is entiled to his opinion but i own the poweraid spacer and i noticed a difference.

I have read that torque is the main thing they provide. All i know is i could stall at 2000 on my pickup when i was stock and not get my pickup to spin.after the spacer i could barely cross 1600 and my tires were up in smoke as soon as i let off the brake.

all in all i can say it worked for me.

LOL! how come all of the quickest LS1s in the country don't use a throttle body spacer? Geez, they are giving up a TON of power!

Can anyone provide a technical answer on why they think these work?

I've got a spacer and it too made a difference!
Hey Nine Ball - Looks like all your schooling has made you even dumber!
It really makes a difference!
