I looking to improve my trucks performance and gas mileage. I was looking at a Throttle body spacer, are they worth it? The one I was looking at is made by AirRaid. I am also looking at buying an AEM Brute Force intake. Please tell me what you think as I am not a automotive guru.

 

Thanks,

I don't think they do much but, if your gonna go with one get a CFM Technoligies spacer. They are the ONLY one with a patent.

Go to cfm-tech.com and check it out...they have a world of info on 350's :rolleyes:

From everything that I have read and studied about spacers is they are great paper weights but do nothing for the performance of your truck.

 

I do have a Cold Air Intake system and it has helped my mileage and grunt from 2200 RPMs on up. I researched this far too much and went with the Trueflow system. It retains the factory airbox so it is a true cold air intake system. It will not make a lot of noise so if you are looking for intake roar, look elsewhere. I would encourage you to check them out on their website. It is a very high quality piece that will do exactly what they claim.

WTF? Have you ever used one?

These work BTW!

Everyones a mechanic when someone recommends something that others do not use. :D

A throttle body spacer will only work on a carburated or (wet system) FI or (dry systems will not respond to them. As for the larger T/B the OEM will support 8L engines anything larger will raise the power ban and lower fuel economy.

If you want more power and economy get a custom tune.

They do work on Throttle Bodies!

They just don't work newer EFI's :D

 

 

 

 

A TBI is a wet system like a carburator and will work to improve the atomization which happens directly below the carb. or TBI. Real FI systems have individual injectors and atomize air/fuel at the intake valve.

Check the only one out there with a patent...none of the others do.

It only makes sense your able to draw air from both bores instead of one.

So many make claims they can't back....

I have one that I put back in the box. It's for an 04' 5.3L. I'll ship it to you for $25. Besides making an annoying whistling sound, it looks cool.

Just because there is a patent dosent mean it works. I know personally that GM tested all T/B spacers along with everything the expermental lab could make work. Nothing would help performance or economy.

Come on..those fuel magnet dooly-mo-bobs have patents....Now you know they have to work....... :chevy::flag:

Its common sense more air more hp if u flow too muchn air ur gunna need more fuel if you read cfm's website they dont try to lie saying that you are going to gain a whole bunch of hp like the other companys do without the proper stuff like fpr and psi balanced injectors they actually say that if u put the spacer in the engine has a risk of running lean. Thats also why they sell inline fuel gauges and other parts to tune the fuel delivery. Becuase just throwing on parts and hoping they will work dosent cut it for them they actually go indepth and explain whay your engine needs more fuel air and exhaust and proper parts to make the engine run the best that it can.

That's exactly right and I can tell you ALL GM's are set lean PERIOD!

That why they make adjustable fuel regulators.

Also...show me ANY stats on where GM tested a CFM spacer and I'll shut up.

:cheers:

Your also comparing a proven throttle riser to something like a Tornado...

AND just because they don't work on later EFI's....don't be mad! :)

Y'all just can't admit your wrong :nono:

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
