[@joshmiller7870]

So I was just reading from ford forums about using the BBK throttle bodies and spacers. Both 56mm or 61mm both will create a loud whistle due to manifold flange opening being slightly smaller than the throttle body. So solutions were grind your manifold to match OR get a throttle body space and grind that one. Also some throttle bodies have that water heater niple coming out toward egr if you use a spacer it gives you room.

[@TheMinuteMasters]

I guess that’s one application where the throttlebody spacer will serve well as a transition. Although I don’t know much about it.

do the spacers lower the vacuum of the plenum ??? eg throttle body spacer and inbetween plenum and instake manifold spacer . i definately have a vacuum leak or lower vacuum ; my c6 automatically shiftd down to 2nd as soon its in drive , is the norm the more vacuum in the plenum is the better the MAP sensor works ????? any1 please reply

[@TheMinuteMasters]

I think in the carburetor days having longer intake runners after the carburetor helped increase lower and torque, and maybe some horsepower. Hence the high-rise intake manifolds that used to stick through the hood. I think that line of thinking was brought to the throttlebody, but it wasn’t nearly as successful.

[@robertmckeown3014]

I have one on my 96 Bronco 351w. It has an ignition and exhaust upgrade as well. All I noticed was a small increase in throttle response at the low end. It was pretty good getting off a light anyway, but after the spacer it was only slightly better. Not worth any big bucks for sure.

[@TheMinuteMasters]

You are exactly right. Not worth it. I attribute the throttle response to the fact that the throttle cable itself is tighter and your throttle plates are actually slightly open all the time.

This is not a good method of testing. You need to run three times on the dyno every time you modify the engine. After that, average the three runs from each change and compare averages.

[@TheMinuteMasters]

Your engine temperature also went up which would affect results. Not saying it would help necessarily. But it would be more accurate of a comparison. Not to mention theoretically you a increasing the amount of air thus increasing back pressure in the exhaust. Which could explain the loss of torque. I would be interested to see what it would do with an larger exhaust

[@TheMinuteMasters]

Iain Kelly There is definitely a lot you can play around with to see if anything more can be gained from the spacer. However, the product as is, requires no tuning to be installed. At least that is how the manufacturer presents it. What I’m saying is, as a drop in mod. It left a lot to be desired, especially at $150 price point.

[@andrewau9542]

I put one into my 1997 Honda CIVIC few years ago and it made a huge difference on my low end. I had much better response on low RPM and I ran 50km more each tank. 4 lbs/ft may not be a thing on your F150 but it makes a difference on small engines and I believe more air into the engine increase the fuel efficiency so that I ran more.

I'd like to see fuel flow and acceleration at part throttle. whats it doing at level cruise 55mph. they really dont do much at WOT as the throttle blades are out of the way at that point.

[@TheMinuteMasters]

MOW PEI There’s probably a lot that can be tested with the kinds of products. I drive this truck around for months with the TBS and I didn’t feel any difference. There also wasn’t a difference in fuel efficiency. I think the way to look at the dyno results is to look at the graph and see what RPM range makes the most power. My rpm sits between 1700-1800 at 55 mph. So if the graph only shows power gains above 3000 rpm then there won’t be any difference or gain cruising at 55 mph.

[@michaelmoreno4250]

The average gained torque was 4, does it help having the ram air duct from a 460, on a truck torque it’s what you need, how about combining it with short headers and what in the gain with aluminum wheels also the drive test summery gas mileage improvement, 50 ohms per foot resistance spark plug wires vs autozone gold, 60,000 summit special coil vs factory, regular spark plug gap vs hot rod trick, 14 degrees vs factory , underdrive pulley set, 2000 explorer rebuilt fuel injectors, no muffler vs super turbo muffler, taking out clutch fan vs aluminum flex fan, all these mods I’m going to do to my 1991ford 5.8 Bronco, I’m also going to add manual locking hubs and hope for the best gas mileage.

[@TheMinuteMasters]

I would add up the cost of all these mods and then compare it to buying a set of heads. I’ve been told by many many engine builders that you might see 15-20 hp from those modes. A set of aluminum heads will get you that alone. I’d start with GT-40 heads and shorty headers first.

[@flatheadfletch]

An engine is an air pump. To get gains it has to pump more air with less effort. IMHO a better exhaust (scavenging system) is always the first mod. 2nd mod allows more air and fuel into cylinders (cam) this may or may not get choked by carb and intake which would be 3rd mod only if necessary (not always). Check cfm at max rpm you will run to determine that !

[@TheMinuteMasters]

Well said and 100% true! I’m told the heads and the exhaust headers on this particular engine are fairly restrictive. I’d love to swap them out with better flowing heads and headers in the future.

It’s not a matter of which is better, because it’s a relationship.

[@TheMinuteMasters]

According to the dyno chart read out, the only power being made was at the top end.

[@David-id2ks]

How many runs did you do? The ECU has to have time to reset.

[@TheMinuteMasters]

The truck had a chance to warm up with the throttle body spacer, and then we pulled three runs.

[@edsimpson6606]

These spacers that create rotational air turbulence truly work at the low end of the torque range such as coming from a dead stop and getting through the 1st gear which is where gas consumption is greatest. From idle to probably 1500 RPM, the cork screw on the Airaid is rotating the air which as the intake air velocity increases as RPM increases the air flow over the cork screw is straightened out behaving no differently than had you never installed the device. On my 8.1L 2500 Avalanche The Airaid added a 1.1 mile per gallon more fuel average going from 9.4 mpg to 10.5 miles per gallon. That's a huge performance increase for a truck set up for low end torque and pulling power. Furthermore, you got a marginal 1 HP increase at the top end of RPM which tells you there is more going on potentially at other RPM and gears before peak HP and torque occurs. These devices are meant for bolt on HP improvement on factory equipment. When you start trying to add these to aftermarket manifolds or with blowers and air chargers, there will be no gains. Also, keep in mind every time you make a variation in any environmental factor such as air temperature or air flow, fuel injection intakes including the early TBI intakes, the computer from the MAP sensor, and the MAF, and the EGR sensors etc. is making constant adjustments which makes it tough to isolate where there are improvements. My fuel consumption is a definite performance increase. However, the fuel savings will never pay off the $135 cost I spent on the Airaid.

[@TheMinuteMasters]

I totally get the science behind the design. But you further prove my point in the video that $150 isn’t worth the small gains. 3 mpg or 10 hp gains would have been worth it.

Should you not reach a bit higher RPM or just for the test? I mean these are rated at like 200ish.

[@TheMinuteMasters]

101spacecase The Throttlebody spacer does not come with a manual showing you what rpm it works best. I relied on the experience and knowledge of the Dyno tech to determine what speed and RPM was good for this test. I can tell you that he did put it up to the max RPM recommended for my truck.

I’m like in this channel. An intake manifold is an awesome upgrade for 150$. I have wondered if a spacer would be better on a carbureted engine though vs injected. I guess that wouldn’t really matter.

[@Cjbarker2]

That’s where throttle body spacers came from. Carburetors and TBI systems benefit from more time in the intake. SFI and MPFI systems don’t really care, so it ends up being a net gain in plenum size.

[@TheMinuteMasters]

Javi Goles No problem man!🤙

[@HealthFitnessMartialArtsDEng]

Right on, man. Interesting from aftermarket cold (hot) air intakes you and I talked about to throttle body spacers, just a no go for HP and torque. So far the one mod that I've done to my '96 Explorer OHV is the 2.25" cat back with Flowmaster Dynaflow 40 from stock 2". She's no longer a slug! Better throttle response and get up and go! There is a resonator still which is nice as I didn't want it too loud. Do you think that if I eventually changed the cat back size to 2.5", that would be overkill? I am kind of thinking it is.

[@TheMinuteMasters]

Yup, this is another expensive junk horsepower mod. A good sized free flowing exhaust is always a good upgrade. As far as going from 2.25” to 2.5”, I was always told 2.5” is max for a stop 5.0L engine. Granted there probably are guys out there with 3” exhausts on their 5.0s. But 2.5” is plenty. 2.25 is probably a safe bet for a 4.0.

[@allmycarsisbroke]

@@TheMinuteMasters Exactly. There is such a thing as too big. The exhaust passage needs to flow as freely as possible in a range of conditions while still being just narrow enough to maintain the necessary exhaust velocity to scavenge exhaust gasses, particularly while under load. If you think about water pouring from a hose, if the flow starts slow, the water just dribbles out until you stop supplying water, at which point the last dribbles at and that's it. But if the flow is strong then when the supply is cut off and the water gets to the end it can actually collapse the hose because the water flows with such velocity that, multiplied by the coefficient of mass (it gets much more complicated but that's the simple way to say it), it creates enough energy that it compresses the hose on the way out. But you have to realize that energy is there all the time, and it's only being used to compress the hose when there is no longer a path of lesser resistance. While the water supply is still open, that velocity actually helps to draw water from the supply (to the extent allowed by other equipment upstream, etc.). The reason this matters is with engine exhaust there is no hose to collapse. Instead, that energy gets used to help suction exhaust gasses from the cylinders through the exhaust valves during the exhaust stroke. Any energy your engine is not spending trying to push exhaust gasses out is energy left to do other things. So by creating this vacuum (often missattributed as "backflow"), it's got a similar effect to increasing your air intake capability slightly, except better because then you can do both and all this amplified activity and volume is spread out across the 4-stroke cycle and engine components. At the micro level, a metaphor would be putting good grease on every wheel of a rollerblade instead of just putting expensive aerospace grease on the first two wheels and crappy harbor freight grease on the last two. Anyway, removing your cats (is illegal and) can definitely improve throughput and performance, but only if the computer knows what the new math is and guides the engine to harness the potential. Otherwise you are doing nothing nut making a vehicle that is loud, and stinks, and runs you the risk of legal trouble, and aside from all that, at best it performs the same as always.

[@TheMinuteMasters]

@@allmycarsisbroke Thanks Nick! 🤙 I appreciate the scientific input.

[@allmycarsisbroke]

Or more simply put, remember this: if you could increase hp/torque across the board by any amount, however slight (and therefore fuel economy) by simply increasing the diameter of your cat a quarter inch, auto manufacturers would just do that at the factory. They have all the incentive in the world to take advantage of low-hanging fruit where performance gains and fuel economy can be improved without unreasonably sacrificing reliability or adding complexity or cost to he maintenance the vehicle needs. This principle helps save me from wasting money on gimmicky "mods" like exhaust diameter, TB spacers, etc. inless and until I can be certain I fully understand what effects it will have. So many people "straight pipe" their cars without a clue or a care that the lack of O2 sensors means their ECU will retard engine timing and make the car perform even worse than it sounds.

[@TheMinuteMasters]

@@allmycarsisbroke You are so right Nick! It’s kind of it’s “too good to be true test”. If TB spacers worked so well, everyone would have one. And, they would become standard equipment from the factory. Yeah I will never understand people going the straight pipe route without dealing with all the sensors and tuning their engines. I think there is a lot of “carb engine” know how that people still think applies to newer EFI engines.

[@abdulalhazred4589]

I think it is in the older throttle body injection systems where you could expect a real gain with ot without a performance filter, being just an 1 inch extension on the newer systems it affects nothing in performance, but in a,say , chevy or mopar tbi, it affects not only the volume of the metered throttle space(vacuum) down to the combustion chamber,but the velocity at wich the air-fuel charge moves, something the computer could adjust in the form of a bigger and longer injection pulses, so there would be a noticiable diffrence in performance, at least in my ´93 mopar engine does, there is a big before and after in torque and hp...honestly, i haven´t done any dyno test, but the sensation at a stop light or towing a very heavy trailer is noticiable... my own spacer was built with phenolic material, it also isolates engine heat from throttle body, something else to think about since most spacers are made with aluminum, a ´´heat magnet´´ to the spot it is attached to...just my opinion...peace...

[@TheMinuteMasters]

ABDUL ALHAZRED I’ve heard the same thing. I wouldn’t rule out throttle bodies entirely. It did make torque and horsepower, just not enough to justice a $150 price tag. Yes, the additional down side of the space I tested is that it is that heat magnet aluminum. Honestly, if I’ve learned anything from these dyno experiences. It’s that if you want to know if these things will work in your specific vehicle and build, then it’s best to just go dyno it and see. I definitely think so mods work on older vehicles but not on new ones and some mods work on new vehicles but not on old ones. You could be the exception. The TBS did change the driving characteristics of my truck. The throttle was touchier and it idled higher. Both make it seem faster in the low rpm and stop light to stop light driving.

Well combining increased HP and lowered torque. I got what you were saying but you contradicting what the graph showed us combined

[@TheMinuteMasters]

Willlerd So I probably misspoke but as I saw it then on the graph and as the dyno tech explained to me. Combining the K&N filter with the TBS increased HP 5 and TQ 1. Here’s the specs: K&N Filter - +5HP and +3TQ Poweraide TBS - +1HP and +4TQ K&N + TBS Combo - +5HP and +1TQ Every time I use the K&N filter I get a 5HP gain. The TBS makes +1 more in TQ than the K&N. The combo only sees +1 TQ gain. So it’s not a reduction in stock TQ it’s a reduction from running only one mod at a time.

[@charleslincoln5357]

Couple points are good but is that enough

A spacer isn't something you install alone for power but in combination it can improve throttle response and mpg or I bet pair with a high rise intake and you would see a little either way sad they charge that crazy amount

[@TheMinuteMasters]

Joshua Maas I’ve had hundreds of discussions about TBS and the general consensus is for they price they are garbage. $150 could be spent on actual horsepower modifications. Carburetor spacers have proven results because it fakes a high rise intake manifold. I believe TBS are trying to be carb spacers.

[@Jmo6570]

@@TheMinuteMasters I mean I would never spend 150 bucks on a spacer like I said it's not a hp adder like claimed but rather something to use in combination with other things I wouldn't use a spacer in almost any situation but you be damn sure it won't be over 40 dollars if I did and yes they work exactly like a carb spacer you are never going to make more power by making the intake taller but like I said you will get throttle response and combined with a high rise and the right cam basically the only time I would ever use one is with high rpm application

But it all goes differently if you had headers and no cats then those up top breathing mods ,bet that would run higher numbers ,kinda like if you put a short header and run your stock cats you might get 5 hp and 7 torque but if you take off the cats and you have headers you might get 15 hp 14 torque my 350 zee did

[@gunfumaster1024]

Combining them might not be as bad as you think, when doing tunes and things you'll often see the max horsepower go up but the max torque go down. This is because the engine produces more torque someplace else in the revs, and as a result you'll gain torque at a certain RPM and lose torque at a certain RPM. It might be the same with this.

[@TheMinuteMasters]

GunFuMaster That is true with combining mods.

[@castleclubclipz]

It would be cool if you had driven around with it for a few weeks, so the ECU can adapt and adjust to the spacer.

[@TheMinuteMasters]

I would still argue you wouldn’t see much of a difference. The throttlebody spacer is not known to make any power. The spacer was on my truck for probably an hour or so for the entire process.

[@castleclubclipz]

@@TheMinuteMasters I challenge you to truly put this myth to rest… Keep the spacer on for a month of daily driving to let the ECU adjust, then test again to compare dyno results.

[@TheMinuteMasters]

@@castleclubclipz I’d love too but I junked that spacer a long time ago. But think about it, if this 1” spacer could actually make a noticeable amount of horsepower, why would the engineers leave it off? This would cost a major company like Ford a lot of money to produce. It just doesn’t make sense. TBS are 100% a failed attempt to bring a carburetor spacer to a EFI engine. Now, I am told lengthening the runners on a plenum produces more torque. That may be the proper area to add a spacer to these efi engines.

[@ihateliberals518]

so before they even get started. i don't see how it could work being horizontal. it'd be different on a carbuerated engine which is in a vertical fashion. that would create a "tunnel ram effect". but we'll see i guess.....game on

ihateliberals Exactly! A spacer with a carburetor makes sense.

[@TripleOgTripleOgTriple]

It's meant for improved throttle response, which it does give, not hp. Also, there's cheaper brands that do the same thing.

[@TheMinuteMasters]

imfrom210texas The packaging says increase mid range hp, low end torque, fuel efficiency, and yes one description said throttle response. Yes, I did see very very small gains with the spacer and the throttle was a bit more touchy. The gains were not worth $150 and the “throttle response” only became more touchy because the throttle cable was tightened by the extra inch added by the spacer. I would even go far as to say, the cable was tightened so much the TB was cracked open a tad. The truck did idle higher and if I did keep my foot on the gas it was roll forward. So, my verdict was this mod was garbage. It’s too expensive for the gains and you can tighten a throttle cable without a spacer.

[@TheMinuteMasters]

old skool83 So the reason I say it’s a waste is I tested the K&N oem style drop in filter. It made 5 hp and 3 tq for around $40. Putting both the space and K&N filter together netted a 5 hp and 1 tq gain. Watch both videos and you will see. I also tested the K&N CAI. Those results were surprising as well.
