v6 sixSpeed. will have the dyno test soon.. so if u guys are intersted let me know
and of course i will hook u guys up with the price and it will sale for more out of this av6 family site...

This will be great. Since we have drive-by-wire, we know any gain will be real and not the false perception from tightening the throttle cable.

Cool! So are you just doing this as a hobby?

What on earth would a spacer possibly do for our overly computer controlled cars?

Could someone educate this noob on what a throttle body spacer is for and/or what it does? Thanks

Well hobby?? depends on how u look at it,hahah....i have a machine shop here in cali, and this is my job, i do stuff for areo space and other companys and since i love cars i try to build stuff for it espeacily the accord, my next project is a turbo for the accord v6 sixSpeed..

as for the noob some one please take him to school, i would galdly explain to him but i don't have time right now im working.. but its all good, gotta start learning form some where...No question is a stupid question....

I'm a noob three, but I went and looked up throttle body spacers online. Here's what summit racing said about theirs, I would assume this marketing statement would apply to any throttle body spacer.

Quote:
exceptional design of the bore causes the incoming airflow to actually smooth out and speed up. This creates a type of compacted air-charge that enters through the throttle body and builds pressure in the combustion chamber. This will result in an extensive gain in the mid-range power band and an overall increase in fuel economy.

Thats true, but the thing is that the trottle body spacer wat it is surpose to do is rush the air throw and spines the air into the engine so u will get a better mixter of gas and air, thus creating air and fuel mixter better, better mixter of fuel and air better it bruns and a little more horse power and millage gain.... if air goes smoothley in, there woundn't be a need to change your stock throttle... i hope this helps...

The thought of forced induction on a 6-speed makes me

After all the exhaust work I did, I can see how easy it would be to install a turbo on the car. I was afraid with the exhaust manifold being part of the block we would have trouble getting the turbo close enough to the exhaust ports. But, after looking closely, the cats are really close to the ports and if they were unbolted, would be the perfect spot for turbos. It would take some effort to take care of all the piping, esp incorporating the intercoolers, but its def possible. (IMHO) The toughest part would be the electronic side of things- Controling the amount of boost, controling the fuel levels, etc etc.

It probably can, but you won't want to boost it by much (makes the $$$ spent not worth much) ... that's unless you want automato tranny soup ..

Wild guess, our 5AT probably can safely handle up to 200-205 ft.lb. of torque at the wheel before becoming clutch slurpee ..

Isn't Acura already putting at least that much through it now??

I don't think the 5AT of the '04 TL is the same as the Accord's.
But you are correct, the '04 TL already puts about this amount.

Most of the caution comes from experiences with the 6th gen AV6 with the s/c. Since no 7th gen FI system exist yet, I haven't heard of the AV6 5AT failling. But I agree .. for auto tranny's stay away from FI applications.

If anyone is willing to try ... please do and let me know how it goes!

How much horsepower do you think the 6-speed transmissions can safely handle?

The price hasn't been set yet, but it will be ceeper for u guys, and its very easy to install i'll have good instrutions for it like all my other old models....as for the psi pressure and stuff i sill have to do some more planing and researching...

I assume you have the 5AT.
There's always 2 ways to make your car faster .. 1. more power, 2. less mass/inertia

For power mods .. I don't think any n/a mods can really break 205 ft.lb on a AV6 5AT so you should be fine. But if you can go over 205 ft.lb., you're better balancing your mods between power and weight.

Reducing your car's weight and moment of inertia actually relieves your tranny from being stressed.

If you oftenly WOT your car while towing a 1,000lb trailer up a hill .. your tranny will blow for sure!!
If you WOT your car with 350 ft.lb of torque but with your front wheels in the air, your tranny will never break no matter what.

The safety margin of <205 ft.lb is for stock weight and inertia (and assuming you want your tranny to last >50K)

You can reduce your car's weight (cf hood, cf trunk, etc) and moment of inertia (light weight forged rims, light weight brake rotors, light weight pulleys)

Weight mods gives you double if not triple benefits:
1. Your car will be faster (especially 0-60mph time and 60-0 braking)
2. Your car will handle better (you'll be more nimble and corner faster)
3. Less stress on your car's components (tranny, suspensions, tires, frame, etc)

This is how Honda mfg their cars in the '90s .. it's just now that people simply go for whatever has the highest HP numbers.

Anyways ... back to the TB spacer ..

After doing much research on the internet, I have yet to find any one single website that is not commercially selling throttle body spacers, that praises the performance gains on fuel injected vehicles from this type of modification. What I found interesting over at a PT Loser website was a conversation about how some guys got pissed that they saw no performance (fuel economy or hp) increase, and then badgered to death the manufacturer until he finally admitted there is no noticeable gains from this kind of install. I believe this kind of modification to only be necessary on carburated/throttle body/tuned port injected vehicles with short plenum spacing before it splits directly into the cylinder intake runners. On our vehicles, once the air passes through the TB and into the intake manifold, it hits a fork (negating any additional air straightening benefits of a TB spacer) and then each bank runs through 3 channels into a larger center plenum divided into two parts (until upper rpms open up the center butterflies). So please explain to me how a spacer is supposed to help when a single particle of intake air needs to pass through 5+ turns before it passes through the intake valve. And since the install process is so short and easy, it should be easy to do a before and after dyno test to prove me wrong.

he claims to have engineered a TBspacer. so pretty much this is his only proof of it doing a damn thing. mileage and power increases can both easily be chalked up to error (which can be pretty big, even for the exact same dyno on the exact same day). but just show me a CFD analysis that lends to his claim, and i will be behind him 100% of the way.

Sadly this is a universal truth everywhere outside the import world. Go to a Mustang/Vette/Camaro or other high HP site asking about a TB spacer and you'll likely be laughed off of the site. While the concept is good, and it has the potential to work, I just don't see gains of more than 1-2 hp. And an amount that small on a dyno is worthless. Back to back runs without any changes frequently have discrepencies larger than that.
The last thing I want to do is rain on anyone's parade, and if there are legitimate dyno gains (on back to back runs, on the same dyno, same temp/density/coeficient) there will be no one more happy than I. But sadly I don't give it much hope.

Most 6th gen V6 guys have the SPC TB spacer and to be honest, I dont think you'll see even 3whp gains from it. You'll be luck to get 1-2. I have it on my car, and I dont notice anything from it except the cool sound it makes.
