replacing the throttle body hose

**DDR2** · 08-06-2004 12:28 PM

anyone do this before? i was told by swapping that rubber hosing to a larger diameter hose or pipe, it could help quite a bit. any validity to this?

it makes a huge diff. if the pipe isnt expanding then u have a constant stream of boost, and if u straighten it out, u get a faster flow through to the TB, but u shoudl know this already shouldn't u ??? ;-).

**fongaroos** · 08-06-2004 12:33 PM

any do this yet?

i never even thought about this...

anyone else have any thoughts or actually done this?

**rex_racer** · 08-06-2004 12:54 PM

there's one guy that has done this, i know it for a fact, i just got off the phone w/ the creator of the product!!! the real ? is who else makes anything like this... then maybe we can get something made for u guys ;-).

**DDR2** · 08-06-2004 01:01 PM

well i just got it done. don't know about a huge difference and not sure if it's just a psychological thing or not. but i did feel it pull a bit stronger. nothing drastic or anything but in theory, at least, it make sense. i'm gonna take the car out later to check again. just thought i'd see if anyone else did this to their audi's. i guess a bunch of vw guys with the 1.8t do this.

any more info on your setup?

whered you get it?

pics?

links?

anything?!

**DDR2** · 08-06-2004 01:32 PM

here's a pic. not a great pic but my comp is messed up so i just had to print the pic off my digicam and scan. got it made from scratch at a place called turbohoses in san ramon, ca. (turbohoses.com is their website i believe) they've never done this on the A4 before, but have done vw 1.8's. quality job and materials though a bit pricey. mandrel bent too. you get what you pay for.

**fongaroos** · 08-06-2004 01:44 PM

hmmmm....

thats very interesting...

so is it a worthy mod?

you said you didnt feel like there were any or much gains right?

**rex_racer** · 08-06-2004 01:45 PM

man u may think their stuff is pricey, but when u add up all the costs of everything and look at the quality of all the parts, u'll change ure mind. i've been there and done that, its worth it. trust me this guys stuff is top notch, MTM already loves his work and he only made one hose so far for the audis!!!

as for how much ure feeling it, what else do u have on ure car??? the more power ure putting out the more ure gonna notice it.

if u guys are interested in this stuff i can get more made for u all. is anyone else making a hard pipe solution from IC to TB??? what about a silicone solution???

**hyperspeed** · 08-06-2004 01:47 PM

how much was it?

**fongaroos** · 08-06-2004 01:48 PM

i dont think it would do all that much for my car...

im only chipped...im not pushing THAT much boost that i would require that kind of TB hose...

the funny thing is, i'm not chipped either, but i had that peice replaced, and there is a deffinite increase in pull at top of 2nd and into 3rd, i never wind out 4th or 5th if ure curious 0=) haha. and if u look at ure stock hose, there is a lot of expansion going on every time u boost, tape a peice of tape around it, go for a drive and look at it, the tape is ripped haha.

**hyperspeed** · 08-06-2004 01:55 PM

high as in.. 20 dollars? or high as in 200? 2000?

**rex_racer** · 08-06-2004 02:05 PM

maybe 200, but that's just a guess, i didn't get a chance to find out how much ddr2 paid, so we'll have to wait and see if he wants to tell us. even before u start tinkering w/ the metal the hoses have already surpassed $20 haha. his stuff is a lil pricey, but when u hear all the rave reveiws that everyone gives on his stuff u'll be in utter amazement, especially when u see some of the crazy stuff he's already made, some of it is just nuts!!!

again does anyone make a silicone solution for this hose, like forge or abd or anyone???

**pkancel** · 08-06-2004 02:08 PM

Someone that knows Turbo hoses want to call and ask them about a Group Buy? Depending on the price, I might definitely be in. Anytime you can more cleanly direct the flow of air via straightening and widening, there is always some gain, as long as it is not so much that the car cant handle it without other adjustments.

what was the cost of this one - off pipe being made and then maybe we can collectively help them with pricing a groupbuy?

that's already in the works

. jus pls someone answer my ?'s hahaha. does anyone else make a product like this??? dont' worry this info won't be used to price guouge u guys haha. oh and the car can handle the bigger piping jus fine, i'm running 2.5in TB piping on my car hehe.

**DDR2** · 08-06-2004 06:09 PM

guys i guess i paid to be the "guinea pig". a whole $200 for that piece with labor and parts. he even crimped the ends of the pipe to hold onto the connectors better. even the clamps are stainless steel. sprayed clearcoat too. mandrel bends. i mean it's a quality job, not anything 90% or your joe schmo muffler shops down the street can do. i just came back from teh santa clara county fair. haha. so i had another chance to give this thing a shot. i feel that it does pull a bit harder than before. nothing that will make your jaw drop but a gain is a gain. btw, i'm not even chipped. hopefullly for not too much longer. all i have is this and an exhaust. so you guys that are more heavily modded may get better results.

**Saturnine** · 08-06-2004 06:16 PM

Ive been meaning to make a set of hard pipes for my car..

its deff worth the money, a production peice would be all polished w/ beaded ends, the best silicone on the market and SS clamps. and where possible the piping would be straightened out for a more direct flow. pipe size would most likely increase as well. if there is a market for this, this and other peices could be made for sale...

**rex_racer** · 08-09-2004 05:50 PM

k guys i talked to turbohoses today and i got some nitty gritty on the price of these things if u want them.

here's the breakdown, the piping will be a polished mandrel bent SS pipe. SS is ok in this application because it is away from all the heat coming off the turbo, so its not tottaly necessary to use straight up T6 aluminum. using SS also drops the price for u guys as well ;). anyhow the correct hoses will be supplied as well as the clamps to secure em. hoses will be Turbohoses R&D hoses, arguably the best hoses being marketed in the world. your choice of color including black, red and blue. the hose clamps are all SS, and very high quality so they won't break.

price range should be about $110-120 dollars. any interest guys, post up and let me know and i can relay the information and get these things into production!!!

**pkancel** · 08-09-2004 06:01 PM

Rex, count me in for sure! Tell them $110 and its a deal. I cant speak for everyone, but enough people on this buy and they should get some great business from this going forward. let us know when we can get them?

Thanks for checking

i can't promise u that it'll be $110, it mite end up being $120, these were just rough estimates from them today. i'll see what i can do though, but come on, if we see some interest i can deffeintly get this piece into production, i know we can do it

.

**DDR2** · 08-09-2004 06:27 PM

for $110 i would say this is certainly worth the money. i'll get mine changed to the SS once it's good and ready. on mine, i think the pipe could be shortened just a tad coz the 45 degree silcone connector you see in the pic above is pinched a little on the inside of the bend. nothing that can't be corrected easily and it's not a big deal at all. but just fyi. i should call hoover up and let him know before they go and make a bunch of these. but yeah, i would say a worthy mod at that price.

**pkancel** · 08-09-2004 06:37 PM

Either way I am in for either price, but just saying they will be more likely to allow the $110 if you tell them the crowd is interested at that and only that. Not trying to be a pest, just negotiating for us all:)

**F16HTON** · 08-09-2004 10:54 PM

This is quite a simple DIY. You can get stainless or aluminum mandrel bends in 30/45/90 or 180 degrees. Total cost in parts will be around 45 bucks. If you take the piping to your local muffler shop, they will cut it on thier band saw and roll a bead around the edge for about 10 bucks. Of course, polishing is optiional, and I would recommend getting some very high quality T-clamps

don't forget the hoses too, u need hoses. oh and btw one of the hoses needs to be a transition hose as the stock IC outlet is 2in. and some place charge more than 10 bucks for bead rolling.

**pkancel** · 08-10-2004 01:12 AM

I much rather have a turn key deal for $110 or $120 so I dont have to take six hours installing and figuring out what part I forgot. I know it sounds easy, but thats assuming you are somewhat familiar with the setup.

I can figure it out with no problem, just dont have the patience or the time and paying at this price isnt really that bad compared to other tubing.

**madrussian** · 08-10-2004 07:18 AM

b6quattro... can you explain that a tad bit more, i'm not against trying because im 1000's of miles from Cali, so that shops out of the q... but i dont think i quite grasp what you're saying.

**rex_racer** · 08-10-2004 11:18 AM

u know if u actually price this piece out, w/ the hose clamps, the polished mandrel piping, bead rolling and the hoses, the price actually comes out being very close to each other. so u end up paying just a lil bit more for something that just drops in, instead of something u have to fiddle w/ and think about.

enjoiweb, b6quattro is saying that u can go out and buy all the parts individually and w/ a lil enginneering u can piece together ure own kit.

**jayt991** · 08-11-2004 06:29 PM

any more word on this? id be interested in one for that price.

**rex_racer** · 08-11-2004 06:57 PM

need more interested buyers. if there are 10 buyers it would come out being about 120s, almost 130 or 130. if there are about 20 then the price comes down.

**pkancel** · 08-11-2004 10:21 PM

Guys, anyone want to jump on this! We should move this to Group Buy or possibly someone can do that for us:)

As I stated, I am for sure!

**LAS** · 08-11-2004 11:42 PM

i'm interested. like to see the piece though.

**rex_racer** · 08-12-2004 12:18 AM

DDR 2 is the only one that can show picks right now...

**pkancel** · 08-12-2004 11:17 AM

Read back towards the beginning of the forum for his pic of the pipe

**DDR2** · 08-12-2004 12:34 PM

just keep in mind that's like a prototype version. it could use a tad bit of tweaking but for the most part you can just use that for an example. as rex-racer stated, you can expect a stainless steel variant of that. that one is is just standard material, i can't even think of the name of it right now (brain fart) T3 aluminum or somethin like that.

**LAS** · 08-12-2004 04:43 PM

ok..........

that doesn't help.

here's a useful pic of jet jockey's intake pipe.

**rex_racer** · 08-12-2004 05:18 PM

the intake pipe is a tottaly different pipe then what was replaced by DDR 2. the inlet pipe made by jet jockey is the turbo inlet pipe that stretches from the intake, or cone filter to the turbo's inlet. the pipe that turbohoses would make, assuming there is enough interest stretches from the smic to the throttle body. two very different pieces.

as for the material that would be used if it went into production, it would most likely be SS in construction, which polishes to a very high luster. and another note about the polishing, that most other places do not take into consideration. each pipe is hand inspected and scratches from mandrel bending and what not are removed as much as possible before the polishing process takes place, ie more time and care is devoted to the pieces. when u polish a scratch, scratches show up even more w/ shiny, so u gotta get rid of em before u polish, if u want the full bling bling effect
