throttle body - exhaust dump

[W.P._Turbocars]

Before this gets moved... This is an exauhst post. lol

Came up with a ghetto idea (and will probably run with it.) I came across a 2.5 inch TB from a Ford Taurus for free and bought a piece of 2.5" pipe from Oriely's...

That's right ... you guessed it. A home build cutout built for under 15 bucks. :thumb:

I'd like some opinions. I figure most will say to save up for an electric or manual cutout, but aren't the electric ones made of aluminum and bolt to a flange?

I have taken all the plastic off of the TB and am making a set of billet bushings at work for the butterfly shaft this week. I'll post pics after a while when I get it installed.

yep they do bolt to a flange, here is a pic

good though on concept, being a cheap person myself it sounds like a good idea on paper try it out, Id personally like to know how it turns out, i dont need a cutout now since i have 3in exhaust but hey you never know when i'll be getting ano:eyebrows:

[ShadowFromHell]

there is a guy on HMT that did same exact thing. Planning on doing the same to my NY. Should work great!

I do plan on hooking mine to a mistu waste gate can that opens around 4psi :)

[W.P._Turbocars]

OK guys. The time is here! I have gotten it mostly put together. Don't mind the radiator clamp. I'll be welding that bracket on too. I tried it out with a pressure regulator and gauge and it appears it will open around 7 to 10 psi. No switches or cables... Totally stealthy! Can't wait to get it mounted under the Rampage. Here are a couple pics for you.

By the way I have under 8 dollars in the whole setup.
Enjoy and let me know what you think.

Damn photobucket is down. Will put pics up as soon as it comes back up.

[turbovanman²]

Pretty neat, I'd be interested to see how long it seals up, :eyebrows:

[BadAssPerformance]

Before this gets moved... This is an exauhst post. lol

I was sure going to 'move' it, but decided to 'rename' it instead. Neat idea...

[W.P._Turbocars]

Thanks for renaming it. At least now it's spelled right ;)

I think it will seal fine. When in vac it will pull it closed (around 20-25 vac.) and it opens up at 7-10 psi. :evil:

[W.P._Turbocars]

Oh and BTW. If anyone else ends up making one, a mitsu wastgate actuator will not work because it doesn't have enough travel.

[Tony Hanna]

Neat idea!
You could probably even add an old boost control, cannister purge, or baro solenoid in the pneumatic line so that you could keep it closed under boost and open it with a switch if you wanted to.

[ShadowFromHell]

whats the air ram from?

[bfarroo]

Opens the TB with boost pressure

[jl93sundance]

Can you take a video when its done?:D

[86trbolancer]

That is a hella cool idea!!!

I'm sure you could get some small motor to operate it if you wanted it electrical...maybe a wiper motor...though that would be kind of big

[ShadowFromHell]

I was thinkin a electric lock motor....

what did you rob the air ram from?

[W.P._Turbocars]

It was in the scrap bin at work. It was for some fixture to cut weedeater tubes or something. I rebuilt it and modified the internals a little to makt it work on VAC and boost.

Yeah when I get it installed I'll try to get a vid. If not I'll hook it up inside the truck and drive with it so you can see it open and close. :)

[W.P._Turbocars]

Also I like having it controlled by boost. That way if anyone wants to race me on the street I don't have to remember to open it. Gives it a cleaner interior appearance. Plus when we take off it'll throw them off guard when it opens all of a sudden and sounds like my muffler fell off. :lol:

That's one reason I went with this cylinder. The whole cylinder and line MIGHT way around a pound and with the Rampage, even though it's already hella light. I am still trying to find ways to make it lighter.

I LOVE how you used a ford throttle body as a dump :D stupid ford's

[SpiritedShelbys]

hmm that's kinda like how the exhaust works on the new(er) corvettes stock only controlled by vacuum.

[W.P._Turbocars]

Still trying to get time to put it on. Crazy AR weather... It was close to 70 yesterday and is in the 30's-40's today and raining. :(

[W.P._Turbocars]

Ok guys. I have an under hood test run video. Hope you like it. I was excited as hell to see it working!!

Enjoy and leave your comments:

put it on the damn car already! :D

[W.P._Turbocars]

LOL hopefully in a week or two I'll get it mounted. lol I like teasing you guys with the projects.
:D

I like how your BOV makes it sound like the TB valve is really working hard! :D

[Ondonti]

ATP sells something like that but its always out of stock and backordered (at least last year). At least you have the means to replace the bushings.

[W.P._Turbocars]

I may start maying these but want to test mine out for a few months first to make sure it's A-OK :)

[turzbo]

cant wait to hear it in action

[W.P._Turbocars]

Re licensed the trucklet today. Will have it on within the next 2 weeks and will make a driveby vid for you guys.

[boost geek]

I'd be interested in one of those cylinders. :nod:

[t3rse]

so the big question for me is...where can I get a cheap 4" throttle body? :D

[Aries_Turbo]

or even a cheap 3" throttlebody.

Brian

[Bbneon95]

I have 2 ford throttle bodies for sale that are pretty big, if interested let me know.

Cheap, I just need a few dolla to save.

[Vigo]

sad thing is most of us have probly had some stupid useless throttle body that woulda worked for this that we already threw away.. i had the ford elbow for my super coupe m90 that had the throttle body and for some reason i tossed that.. and now i wish i hadnt, for multiple reasons.

[Ondonti]

Anyone have an idea how small and light you could make a rear exhaust that would sound similar to stock...yet be really light? Would be sorta cool to use a super tiny exhaust instead of a huge loud one with this device.

[Aries_Turbo]

titanium? lol

use a tbi exhaust with the dump up front.

Brian

[Ondonti]

2" aluminum exhaust woo! Ive heard aluminum muffles pretty well when used for exhaust.

The ATP device like this is STILL on backorder a year later!

Imagine 2 step antilagging. Car goes from a whisper to a warzone.

[pauly_no_van]

That is a great idea!
I had an electric valve on my first van that always leaked when closed, but it was fun to scare the smartass next to me at a lite.

[W.P._Turbocars]

Guys I have it mounted. Flet like giving another teaser. lol. I'll put a vid up in a lil bit. Wife is gonna run the camera while I give it some boost. Also, I tried a couple different things and the best I found so far (for me anyways) is that I left the factory spring off of the TB. I had it on as I figured it would help seal it off at ~5-0 VAC but it doesn't need it at all. So instead of opening at 14 PSI I now open at 5 PSI. :D

[pauly_no_van]

u can always grainger it :D

[W.P._Turbocars]

u can always grainger it :D

Exactly what I was thinking.
Got a couple of vids today but neither one turned out that great.:( Gonna try to get a better one sometime this week.

http://s107.photobucket.com/albums/m282/wp_turbocars/?action=view&current=parts046.flv

[W.P._Turbocars]

And before anyone says it... Yes, I need to take my steering wheel off and straighten it. lol

[Darkapollo]

heh, thats really cool!

[W.P._Turbocars]

Here's a pic of it mounted:

http://i107.photobucket.com/albums/m282/wp_turbocars/parts048.jpg

[Ondonti]

Do you think its possible to get it to open at a lower boost pressure?

[W.P._Turbocars]

Lower than 5? No. Maybe with a different cylinder, maybe, but I doubt it. This TB has ball bearing rollers in the ends and the best I have gotten so far was 5 psi.

[omnation]

Hmm. When it opens it sounds like V-Takkk is kicking in yo. :p


Honestly though, put me in line if you plan on selling some.:thumb:

[Ondonti]

whats the exact blad diameter on that TB?

I am sorta liking the idea of a 2" aluminum exhaust but a 4" downpipe with two of these things (if they are big enough).

[Aries_Turbo]

im thinking about putting one at the rear of my k car or daytona with a quiet muffler and using a solenoid to open and close it. :) no chance of overheating it there.

Brian

[TheCanadian007]

Any ideas how to make it remote controlled with a solenoid?

[W.P._Turbocars]

whats the exact blad diameter on that TB?

I am sorta liking the idea of a 2" aluminum exhaust but a 4" downpipe with two of these things (if they are big enough).

The exact inside diameter is 2.5"... Not sure what a "blad" diameter is lol.

As far as using a solenoid... I was going to go that route but decided against it since I couldn't find anything with a long enough stroke for a decent price. Even with the TB under my seat it isn't that hot. I can grab it after my 15 min drive to work everyday and it's just warm. The cylinder stays cool.

[tkelly27]

One could pretty easily use a pressure canister with a check valve and a solenoid to get this thing to open whenever they wanted. Or use a vacuum canister along with the pneumatic operator of a PCV valve or an old broken BOV.

As far as the throw goes, putting the actuator arm closer to the center of the TB shaft could help shorter throw devices get a full opening. Just got some new tools to try this with my 60mm ford TB : D

I've seen complete aluminum exhaust systems before, so this should hold up and not melt. I'm not sure if the expansion rates will cause the TB to get sticky over time or under high load though. W.P. doesn't seem to be having problems with it.

Wow thanks for bringing my thread back. I had forgotten about it.

Guys this thing works great. I have only had it stick one time and not too sure as to why. It was the only time I had eve rdriven it ~40 miles without hitting 4.5 psi or above and it stuck. All I did was reach under the truck and hit the "throttle" and all has been well ever since. The only downfall is the cops are starting to catch on but not in the way I thought they would... They think I'm gouging it any time I hit boost lol.

I will see what I can do to get some made up for sale too for you guys. :thumb:

[turbodaytona87]

A servo motor might work well too

[W.P._Turbocars]

Yeha it would but it all comes down to simplicity. I didn't want to run and wire or a cable to mine. Plus I never have to open it. That way they never know what hit em till it's too late. :nod:

[crazymadbastard]

I was thinking of using a daytona or lebaron headlight motor to make open close.

[Vigo]

My original thought when i came up with this was a wastegate actuator off one of our stock turbos..

And i still might because i have a cutout pipe with a cap on it on my van and a header flange that fits it so if i made this thing i could just bolt it on with no cutting/mods.

I had bought an actuator from a member on here and planned to do the same thing with it but it did not have enough throw to it.

[Vigo]

Yes but you used the stock attachment location on the throttle arm and the stock return spring, right? It is hard to tell in the pics..

But i had assumed changing those things. If i ever try it, then all will know whether i succeeded or not, but for now i need to just the van running again : /

[W.P._Turbocars]

No. I have it as close to the center of the throttle arm as possible. You can try it but good luck. You may want to get the van going first though. :)

[pauly_no_van]

I have a tbird supercoupe TB to try. I think I am going to hook it to the Intake TB and make so it opens/starts to open around 1/2 throttle and is open all the way at full throttle.. No cruise so there is an open spot and I have many spare cables:nod:

[Vigo]

annoying thing is i had a supercoupe tb as well that would have been a good donor and i tossed it for some reason without thinking. oops.

[Ondonti]

Did you replace the bushings with something fancy or are the stock ones still working?

[W.P._Turbocars]

Did you replace the bushings with something fancy or are the stock ones still working?

Stockers are still working fine. It took a couple days to burn the plastic covers on the bearins off for it to work every time I hit boost. If it was just started up and I took off it wouldn't open the first few minutes. Now I can go out and start it and it opens just fine every time.

[Aries_Turbo]

you could probably bake one in a grille to take care of that problem :)

Brian

[turboaddict]

after talking last night what did you use for a flange for the tb?

[W.P._Turbocars]

I just used a piece of flat steel and cut the center out and drilled my mounting holes. For a gasket I folded up some aluminum foil about 1/4" thick and cut the center out also.

[Dez]

Neat idea, man!

[W.P._Turbocars]

Was goofing off and found my old thread on here. Figured I could give the update that after almost 2 years my cutout still works flawlessly. :)

[Ondonti]

You should see how much Sound Performance is selling a comparable device for.

[W.P._Turbocars]

Wow... I shoulda been sitting down for that one. :wow1:

Looks like I need to make a batch of these and sell them for about 120 a piece.

Any buyers? lol

[tryingbe]

I'm interested. I'm sure there are enough interest to do a group buy.

[shelbymonster]

thats nice i want one

[ShadowFromHell]

Haven't you put less then 10 miles on it in those two years though? :p

[Ondonti]

Yeah well, I guess you are glad you looked ;)

[W.P._Turbocars]

LOL still more than all your turbo mopars combined! LOL

Let me see what I can do guys. If I do them up they will all be 2.5" for now anyways.

[ShadowFromHell]

Na, Ive put 1k on the CSX, and easily 2k on the NY in the past two years. Both of them still run too... Just costs to much to drive them (should have never bought that neon!)
