 Subject: TBS...Power or Junk

Message:
Hey I put on a TBS on my 2001 5.9 along w/ my new intake and people are tellin me the TBS are junk don't bother w/ em, but they don't give me any proof that they don't work. I mean have U done any tests or seen any charts someone has done from the track? Just because some dude says ohhh these are junk don't get em don't necesarily mean they don't work. I drove my new truck around for awhile right out of the dealership. Then drove it around w/ the new intake on it awhile and noticed the increase in HP. Then last weekend I added the TBS and could tell even more power added when I punch it at a light. I heard of a guy returning the TBS just cuz it whistled everytime he drove it and he thought it was stupid and didn't work...thats not proof that it don't work just someones opinion. If you know for a fact they don't work and have tested it tell me where I can go that shows a chart that they don't help any so I can solve this once and for all.
Thanks -Mike-

Throttle body spacers work on engines with the injector in the throttle body. They dont do much for the dodges 'cuz their injectors are at the intake valve.
I'll let Bernd 'splain it:
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.
