 Subject: Throttle Body Spacer Debate

Message:
Ok. I've heard a lot of different things about throttle body spacers. There are the "screw type" ones, like Power Raid, Air Raid, Power Tower, and most all of them, and then there are the ones that are smooth with no swirl like the ones by AEM. Which is better? Also,I've heard they have no power gains on Magnum engines, only on Pre-magnum ones. Are they a waste of money on my 92 Dakota 5.2L 318? Has anyone put one on a Magnum V8 and had it dynoed?
Please help me!

Throttle Body Spacers (Primarily the "Helix" style):
These spacers do not provide any gains in HP at all. They claim to increase TQ and MPG but we tested one and it gained nothing. The Dyno showed no gains in HP or TQ. We also had contacted one of the manufacturers for their comments on them and here's the direct quote (from email):

Dear Sir, thank you for your inquiry in our products. The spacer makes no HP on the Dyno. It makes all of it's power in torque in the low end. If you haven't noticed any power on the Dyno or the track then it's doing what it's supposed to. You would not see any gains down the 1/4 mile or increases on the Dyno. The idea of the spacer is to improve overall drivability and fuel mileage. In most cases when people install a bolt on part they expect better mileage and power, what happens is they are into the throttle a lot more than before trying to test performance and that's when the decrease in mileage happens.
Sincerely,
-------------------------------------------
Points to look at:
"The spacer makes no HP on the Dyno. It makes all of it's power in torque in the low end."
"If you haven't noticed any power on the Dyno or the track then it's doing what it's supposed to."
"The idea of the spacer is to improve overall drivability and fuel mileage."
So...it doesn't make any more HP, is not supposed to help in 1/4 mile performance (or on the Dyno), and is mainly for mileage and bottom end Torque. Well, Dyno's show TQ figures and there were no changes, mileage stayed the same, and 1/4 mile performance wasn't affected on the several others who have tried it (including us). They also are still not able to explain how the spacer keeps the swirl effect through the two turns (90 degree and 45 degree) in the intake plenum of the Dodge Ram/Dakota/Durango manifolds.
While the Throttle Body Spacer showed no gains on the 3.9/5.2/5.9L Magnum engines, the 4.7L engines have been reported to show noticeable gains from the spacer. Why? It's a much more efficient intake system with less restrictions than the Magnum engines. It may work just fine for the 4.7L crowd but we'll look into this at a later date for Dyno and long term MPG testing.

What a load of crap. A more efficient intake shows more improvement than a lesser one. Yeah, and I have a bridge for sale. Oh, and before anyone chimes in recalling the demonstration of that "tornado" device....yeah, it works great with water. However, air is just a bit less dense and is compressible. Think about it.

Aren't the Dakota's direct port injection? And if so then all the throttle body does is flow air right? Isn't the idea behind a throttle body spacer to space the throttle body out a bit so the air fuel mix can have more time to increase the velocity going into the chamber increasing atomization of the air/fuel mix? If our trucks are direct port injection then there is no fuel going through the throttle body so it wouldn't do much of anything would it? The spacer ideas do work, I have seen them work, on carb'd engines and throttle body injection engines. As for the swirl crap, is just that crap. It doesn't swirl, the air goes over the swirl louvers and becomes turbulent.

I see Trucker magazine dyno tested the Tornado and a couple of TB spacers in this months mag. Each caused a LOSS of 2-4 HP and 3-5 Lbs of torque vs stock!
