This thread is for Throttle Body Spacer Discussion

As title says, it needs to be pointed out and discussed in my opinion since I see too many members here down talking them. I have seen POS, paper weight, scam,etc... So I defend only Taylor Cable, and believe they provide some small gains, but still a gain is a gain. Please don't bash or get irate. I went ahead and contacted them and wanted some dyno charts for proof vs. what they just claim. They sent me two different vehicle dyno sheets but on non Dodge vehicles. I have done many mechanical jobs from planting and pulling engines, swapping complete cobra intake(upper,lower,plenum,throttle body) to my 5.0, header installs, gear swaps, and even port and polish throttle bodies,plenums, and heads. I also became a believer in Taylor Cable spacers. If I am delusional, please just point out why I am wasting my time and money on these Taylor Cable spacers here on this thread. Thank you.





Working on the dyno sheets still... they are PDF form. Only thing I found was to snap pictures off my tv and upload to photobucket.
Here they are:

not sure what spacer is the one that i saw but i saw a back to back dyno on a colorado 5 cyl and it lost 5 hp with the spacer but thats just one truck ive seen i have no other proof

I'd rather see an independent test done rather than have the product manufacturer send me some dyno sheets and ask me to "trust them". Who's to say those sheets are accurate, or that all that was done was a throttle body spacer? Because that's what they typed into the dyno?

Hmmm, I know brand in alot of products does make the difference. Also instal is important with these.... They must be centered and lined up with the intake manifold and throttle body precisely before tightened on. I get them hand tight, then open the throttle body to make sure all is lined up good so no lips are created which would create drag on the air flow... that can cause a decrease in Hp.

Ask Taylor if they will let you dyno it yourself on your truck. If you dont see a gain, then send it back for a refund. If you do show gains, then tell them you will spread the word on all the truck forums for them. For them to claim 22hp/25tq and 4mpg gain, they must be very confident in their product. If they stand behind their product, then this should be no problem for them.

You know, if I was close to them, I surely would open a cross promote option to do what you say. However, I do have that thought personally when I do my dyno runs this spring. I am hoping prices are not too steep, and I will remove it between pulls if all works out. I have stated though, I am one of the most craziest detail orientated people alive. I know what my vehicles do before, and after on mods. I have bought the Taylor Cable products from wires to spacers for more than one vehicle in my days.

Still, If I am delusional, the dyno will tell tale.

Just for clarification, my immediate reason for this spacer was for gain on MPG. Hp and torque would be nice, but not counting anything there. I have monitored a slight increase in mileage today since installed. I'm going to refill and set my Dodges computer to the mpg increase tune. Had it on 93 performance tune today, traveled 239 miles with several WOT passes and used just a hair more than half a tank.

I'm in for updates.

Interested in your experience. Not sure I believe their claim of 4 mpg gains

Q- shouldn't you keep the same tune you were using before installing the spacer, so its apples to apples? Unless you documented your mileage for many tanks in the mpg increase tune before the spacer...

Interested to see. Hey- this is with a stock TB, right? Would be VERY interested to see a spacer with a Moe's 87mm

I have one down stairs and it was the first ever mod I bought stock motor no tuner. Without a long post and the 225 bucks spent on 2x colder plugs that didn't help either I got rid of it. A total waste of dough and from that point on I learned my lesson. 4 Cam swaps later a lots of dough I have her where I want it. Went through the CAI that came with a spacer too. Tried both in and out and in the end am running best power gains with K&N drop-in, MIT, Power Wire, and Ported TB. On my Crazy Spartan Magnum I chose the K&N Typhoon as the Mopar one comes with a spacer so no way was I going there again. My truck ran rich when the Helix was on there as my tail pipe was charcoal black. I don't have any of those issues now. So on a rear mounted Hemi intake I say no. Maybe on the newer motors with the intake up front it may work. Edit: Or on a 4.7 Sorry should have seen that before I spoke......Too bad for Taylor as the make good wires. I did read posts that the vendors of these spacers usually get run outta Dodge when they try and peddle the spacers at shows etc because of the proven gains argument but thats just what I read a few years back. So went long on the Post, good luck in your quest.

So.....you "swirl" the air going into the intake....where it splits off to the 8 individual cylinders through 8 runners. Do you really think that "swirl" is maintained all the way to the intake valve?
The ONLY reason for this would be on a carbed motor where you may wanna induce some turbulence to mix the fuel better with the incoming air. Our fuel is injected much further down the line....there's nothing to mix. The mixing is done in the cylinder via the swirl caused by the shape on the intake runners, valve shrouding or lack thereof and the shape of the cylinder itself.

A TB spacer on a motor such as ours can not and will not do anything.

This^^^^^^ Its true and been known for years. This is not a new topic of debate but it is a topic that will never die. Works for a carb engine not a injected one. If anything any TB spacer would just cause more drag then a smooth tube.

Through out my wide range of picture posts here and there, mileage was for the most part only recorded for the first quarter tank and half tank. A spacer is matched to stock specs, so with a larger ported tb, or after market larger one, the spacer would have to be ported to match as well.... in which most cases it becomes just a spacer without and air manipulating pattern on its inside. All of my first picture recordings had been made after a K+N drop in filter, a Flowmaster super 44 muffler, and a MPG increase tune. The main difference is my driving habits(WOT' passes) and city vs. highway. From going between the Diablosport Trinity T-1000 MPG booster tune to Superchips MPG+ tune- I have to side with greater gains over all on gas mileage from the Diablosport. Still, Superchips provides a more aggressive canned tune. Back to the spacer, I have recordings made, and have monitored that the octane rating has also effected over all mileage differences. I'm still paying attention and snapping pictures during gas consumption.

Interesting because alot of members from other forums I am apart of catch absolute rec on people using spacers on Carbed engines vs fuel injected. I still believe regardless of any inside design, adding a spacer after the tb, still provides a bit more air ready to enter when WOTed. Gains may be small, but its either you get a dyno run with and with out one, and/or record mpg info like I am to just find out.

the added air post TB from a TB spacer is so minimal. A TB could possibly cause "extra" turbulence but it would have more effect on better mixing the fuel and air then it would "spinning" the air faster into the cylinders. Thus, in my mind, only fueled sprayed before the cylinder would let a spacer have any effect. And with that train of thought a carb would have even more effect then a port injected motor due to the amount of time/distance the fuel would be atomizing in the air. Which we all know:better atomization=more power and MPG. Please prove me wrong.

"Which we all know:better atomization=more power and MPG. Please prove me wrong."

No sir, I agree 100%. Regardless of gains made in other kinds of vehicles, I have had my doubts about one on my Dodge since first installed. That is the main reason I am recording MPG, and still looking forward to the Spring dyno runs offered where I live...

lol did not need the atomization stuff disproven. Looking for my the TB spacer on a injected motor opinion proven wrong. Unlike most people I encourage my beliefs to be PROVEN wrong. Just means I learned something new. I dont take MPG much into account, even more so if its minimal and not done in a reproduced actions pre and post change. However back to back dyno runs with the single change of a TB spacer I would very much like to see. And no I dont trust a manufacturers dyno charts without a ton of info to back it up. Videos dont hurt either.

93 octane tune, WOT x many = 390+ miles to a 26 gallon tank (around $75ish).

As far a "swirl" talk goes, it doesn't stay in that form through out entire travel. For the short section where "swirl" life is happening(intake manifold directly after the t.b), it pulls and pushes the air a bit faster. Id say more during WOT vs. other driving conditions.
