vts bored out throttle body

11th August 2006, 19:20

i was on the ssc website and a user on there has a vts with a bored out throttle body, anyone got any pics of a vts throttle body off the car and close up as i might have ago at boring mine out

11th August 2006, 20:02

hold on, i think i have a pic of mine done.

11th August 2006, 20:05

you can't really tell the difference in the pic but here goes. left = standard, right = bored out.

I'm glad you asked this as I read about it on SSC and I thought it sounded like a good idea.

WillimasVts did it make any difference and where did you get it done?

11th August 2006, 20:10

cool cheers for the pic, looks like its nice a shiney thats why the cam reflected te flash, think i'll take mine off over the weekend and have a little look and see where i can bore out and smooth and inperfections as all these little mods help the big picture and cost bugger all to do. shame u dont have a close up hi res photo

great minds and all that mate

what are highflow heads like for p&p heads quality and pricewise?

11th August 2006, 20:17

Do they have a website?

Google is currently saying they dont.

11th August 2006, 20:18

i have no experience with their heads but i think the quality of their work is supposed to be good. iirc they have a good few years experiance.

i have emailed hiflow head askign prices and maybe get a group buy????

i am also going to have ago at porting my exhaust manifold like so:

Williams _ What mods has your car got then and have you got bord off SSC or just expanding your horizons?

11th August 2006, 20:24

I love group buys they force you into buying stuff you wouldn't normally consider as the chance of missing a "Bargain", so rather than waiting you blitz a load of cash to save £10 (lol)

stop tempting me it isnt helping me save either

williams-tidy spec there mate what sort of power is that putting out and are you taking it any further?

11th August 2006, 20:42

not sure what power it is atm. looking at about 155-160 after its been mapped.
need to get my gearbox finished and that will be it for this year as i want to get plenty track action in next year.

maybe get a decent head next year, or if i have the cash throttle bodies.

not bad,thats roughly what i want out of the next project

12th August 2006, 08:35

I'm no expert on Cams but on Hiflowheads why is there such a price difference between these two:

"Competition Parts Price (£)
Fast Road cam (Reprofiled) 270 , exchange 165.00
Fast Road 'Billet' Cams /285/300/320 Duration 466.00 "

?????????

I want this :

Comes with Eaton Supercharger, boost gauge , Omex 6000 seriers ecu , fully assemblied, fully dyno'd & Fully mapped. Just Plug & Play ! £5541.92 "

The price tag puts me off though

12th August 2006, 11:42

Fcuk me your making my heart beat like a beast seing that!

id be well up for a group but on the ported throttle body!

i was thinking that on the cams theres also a bit of a difference on the 150 and 160 bhp packages and the only difference is the cams the 150 kit has 270 degree cams and the 160 bhp kit has 285 cams and there is 155 quid diffrence

12th August 2006, 12:19

fast road billet is a brand new cam ground from solid billet and reprofiled isnt

12th August 2006, 18:29

ok peeps i took my vts throttle body off today to see check out boring it myself, from what i can see the main part that needs to be bored is the top part under the seperate idel control chamber as it has a largeish restrction point that looks like it is there from the manufacturing process, i didnt manage to get any pictures as my digi cam is broke but i am borrowing a mates tomorrow and will get some pics up

12th August 2006, 18:40

yer it would be nice to see the pic as i cant really be botherd to get all my induction off today to have a look.

hows it goin williamsvts i was havin a chat with you the other day on ssc about the headlight air feed. finished mine today! used the fog light though. ill post some pics iup in a mo!

12th August 2006, 18:55

i have made up a pic to show you what i mean, soz about the crap pic i'm on a macine without photoshop as i'm not at home so had to use paint but you get the idea:

12th August 2006, 19:06

I'm very impressed Steve, keep up the good work

12th August 2006, 19:07

sound mate! im gettin the dremmle multi on her tomorrow lol

also heres them pics. iv only just finished spraying it so ill take a pic when its on the car properly. its got some 4" ducting coming off it that goes along the side of the power steering pump then up under the battery ad is touching my filter.

i had to smasha the glass on the light the pull out the rest of the glass with pliers.
as you can see iv moulded some meshing in to stop leaves and big stuff getting up into the engine bay.then i built up the sides with fiberglass comp and then smoothed filler over the top and did it over with wet and dry. now its sprayed black. looks ace now its finished!

12th August 2006, 19:20

rep sent for the diagram mate!

14th August 2006, 22:56

i got an email from hiflowheads a few mins ago, a ported throttle body is £55 + vat + £6.50 carriage, i'm still gona have a go at doing it myself, i'll let you know how i get on

just be very careful when going through puddles with an air feed so close to the ground !

15th August 2006, 08:35

its no a direct fit to the throttle body. its just the same as a normal air feed. the filter wont suck air through it and i dont plan on going through puddle a ffot high bit i see where your coming from mate!

im havin a go at porting my TB too

15th August 2006, 12:06

Thats tempting, but i want me wheels and coilovers :-(

15th August 2006, 12:34

Interesting

Good digram there mate.

Still confused as to why Citroen would restrict the TB? Can't make that much difference to emissions etc surely?

15th August 2006, 12:43

they wouldnt restrict it its more than likely just whats left over from the manufacture mould. the throttle bodys arnt gonna be perfect are they? with mass production they want things made as fastly and cheaply as possible!. in a way its just like changing your manifold for a 4 branch. citroen put a cast iron, squashed together manifold on but you can buy a 4 branch and you gain performance as the you dont get full potential with the standard one. its the same with the throttle body they wouldnt purposely restrict it but there are areas that can be bored out and polished that will make the air flow better and in my opinion it can only give you gains! it wont lose power giving the air a bigger easier passage!

15th August 2006, 19:43

How are we propisng to do this DIY bore?

15th August 2006, 21:02

you just want a drill with a stone wheel, a couple of flat wheels one course and one fine and a buffer drill bit. i ot loads in the garage. i had a look at it today to weigh things up and it WILL DEFFINATLY free things up in the lower down revs cause you can see that untill your butterfly opens past about 15degrees (90 degrees being fully open) air can only get in to the inlet manifold through the gap at the bottom of the butterfly but if you take out the restrictive bit at the top it can take in air from the top and the bottom.
You'll see what i mean if you have a look into your throttle body and open and close the buterfly.

i had a look on a vtr throttle body iv got in my garage and they havnt got this restrictive lip at the top of it.

ill grind the majority of the lip away with the stone wheel on the drill, then get the course flat wheel and tidy it up and also take about half a mm off around trhe whole of the circumference then il smooth it out with the fine flat wheel then polish it with the buffer. wont take too long.

is there any way of getting off just the throttlebody without taking off the actual inlet manifold? i didnt look at that while i was under the bonnet and is it easy if there is?

cheers guys

Dan

15th August 2006, 21:21

Nice on dan I'll give it ago but maybe after Trax as I have loads of things to do so could do with out messing the throttle body up.

15th August 2006, 21:32

yer id leave it till after if i was you too mate. i might do mine tomorrow night so ill post pics and let you know the difference as soon as its done!

you sound like a sound lad mate. will have to have a chat a one of the meets if i can ever get!

I look forward to the pics then and I'm appearing at Trax this year, what about you?

15th August 2006, 21:41

dont really know mate. i seem to have loads of time on my hands but not much money as im renting the misus at the mo and am saving for a bit of a deposite for a house. im hoping to get to some meets though. mte be short notice like but ill try!. they all seem to be miles and miles away from mee too! i dont live all that far away from you mate. i live about 10 miles the other side of Tamworth from you. i go over cannock every now and again to a motocross track i race at

15th August 2006, 21:47

Let me know if you go and I'll say hello.

I didnt realise you were that local Tamworth is only a short blast down the A5.

15th August 2006, 21:49

yer i know mate. i live in a town called measham dont know if you have heard of it but as i say im not far away at all dood!

15th August 2006, 21:56

Dan

there are 3 5mm alan key bolts holding the throttle body on to the 16v inletmanifold, your plan is exactly how i am going to do it but i am still waiting for the dremmel back from a mate i let it to ages ago lol

15th August 2006, 22:10

I can see this being the latest Sax-P craze, diy wheel painting was so last year.

Dont forget your progress pics people

16th August 2006, 10:28

i wont forget the pics mate! i joined the wheel spraying club. came out ace! really smooth with some twat cans from halfords! lol

16th August 2006, 19:42

will have 2 hve a play with mine cant b that hard to do

16th August 2006, 19:57

if i bore mine out will it fuck up the air flow ??

17th August 2006, 10:32

no it wont fcuk up the air flow at all. it will help it! thats why you bore it out! did mine yesterday but it isnt finished yet. i can still take some more off. i also need to get a real small flat wheel too as you cant really get close to the spindle of the butterfly.

17th August 2006, 11:21

how much have you taken off so far dan? have you run it

17th August 2006, 20:31

as you look straight into it iv taken about 3.5mm off that top lip, smoothed out the groovs at the bottom that run up to that sensor and iv taken about 0.5mm off the wall thickness around the whole circumference. i can go double what i have but tit took a while as i couldnt get the sensor out the bottom. so was having to be real carfull of it. i ran it today and you can definatly feel a difference already! and im doubling what iv already taken off. basically, taking that top lip off allows like twice as much air through in the lower revs, it deffinatly pulls better and its asthough the power is sooooo much smoother! you know how usual the vts will just kick you in the arse at about 4500rpm well now its bended in and really smooth! deffinatly a must! gonna do the rest at the weekend

Can you post some pics up cause i wanna do mine thi weekend

17th August 2006, 21:02

my throttle body is back on at the minute mate but if you click on page one of this topic you'll see williamsvts's throttle body pics and the standard one on the left you can see that at the top of the big inlet whole it is kind of oval shaped. all you need to do is make that so that ist a perfect circle and then smooth off any other groovs like at the side where your main intake joins with the idle slit at the top. you'll see that there is a groove either side. just make sure its all smooth all the way round and that the inlet it more of a circle than an oval. and metal you remove will make A difference mate! just remember to take your time and dont grind a hole straight through the wall of your inlet lol (got to be a dumb mother to do that thogh) lol and also

MAKE SURE YOU WIPE OUT ALL OF THE SMALL FILINGS THAT WILL HAVE STUCK IN ALL THE LEFT OVER NOOKS AND CRANNYS. otherwise you'll be nursing scored barrels!

hope im gonna get a rep for these instructions. lol

only jokin

17th August 2006, 21:11

Sounds good Spencer I'll get mine bored out in the near future.

How long did it take you?

Steve its down to you to produce to the step by step guide for me to follow

17th August 2006, 21:16

i got it under control lads, hopfully have pics this weekend as i should have the dremmel back

17th August 2006, 21:46

just a quick couple pf pics to keep you boys and girls happy:

ok this is a pic of the throttle closed and as you can see you can see more of the bottome part of the butterfly than you can of the top you can also see part of the shaddow the lip is creating on the butterfly:

her is a pic of the throttle slightly pen and you can see that the bottom part of the butterfly is allowing air through but the top is allowing nothing through:

here is a picture of the lip that needs to be bored out, it doesnt look like it in this pic but its angled outwards:

here is a picture of the other side of the throttlebody and as you can see there are no restrictions:

and finaly here is a pic of the diagram i drew to try show it a little more simpler as you really need to see the throttle body in person to see how its restricted:

17th August 2006, 21:50

Good man

17th August 2006, 21:52

nice pics mate. i cant get te sensor out that you can see at the bottom of the inlet. so im having to be really carefull with it.

also without having a look. can you take the butterfly out? it would help loads!

17th August 2006, 21:52

and also smoothen and bore the rest of the throttle by by .5mm and polish it smooth

17th August 2006, 21:54

Is this a standard VTS T/B it looks to be bored out if not?

17th August 2006, 21:54

also smoothen the ridges on the side where it splits for the idle intake. less metal is better! IMO

17th August 2006, 21:55

I planned to smooth everyting over.

I might go for a chrome look to match the rest of the engine bay

17th August 2006, 21:56

thats not a standard one mate. nothing like one. where did you get that pic from? the turbo is making me druel .lol

17th August 2006, 21:57

thats what i did lol. mite as do the outside of the T/B too ay! a nice wire bruch wheel brought it up real nice! there are some hard to get too places though!

17th August 2006, 22:03

That one make me druel.

It came from SSC

17th August 2006, 22:06

ooo ya fucker!

now thats a beast!

wouldnt you just love for some one to give you that for free!

17th August 2006, 22:09

Yeah I'd be happy to have it for free, I might be willing to sacrifice some dignity to get it

It looks like a complete monster I've mailed the lad to try and get some more info as I was that impressed.

I'll let you know what I find out.

17th August 2006, 22:18

How many turbo's can you see?

17th August 2006, 22:20

yer sound mate. i cant wait too see what you think to the difference when you port out the T/B on your vts. i didnt think id notice anything at all but i was surprised! more of a difference that fitting an airfilter or a de-cat pipe!

17th August 2006, 22:21

its a good old twinny!

I didnt notice at first glance but thats just insane. I've never seen turbos stacked on top od each other like that usually they have separate pipes.

As in a twin turbo or have i picked you guys up wrong? Theres only one turbo there

18th August 2006, 00:12

lol, just had a look at the pic.

have none of you seen a turbo?? (apart from scott)

the shiny side has the compressor wheel and the rusty side has the turbine wheel.

that is 1 turbo.

18th August 2006, 00:29

i think there mistaking the external wastegate in the pic as another turbo behind the turbo

18th August 2006, 07:54

I'm blaming Spencer as I asked him how many Turbo's can you see and he answered its a Twinny.

This has nothing to do with me being stupid

If any mods want to delete this twin turbo malarky? I'm more than happy for the posts to dissapear.

18th August 2006, 12:32

yer mee too! lol

18th August 2006, 13:46

thats andydeas old bits sold them to someone on ssc, its a GT28RS dual ball bearing, 3" throttle body and metal inlet, 3" exhaust from turbo with 40mm external wastegate, lovely bit of kit, shame its never hit a car yet

18th August 2006, 22:04

Will this tool be ok to bore it out ?

http://www.maplin.co.uk/Module.aspx?...Tools&doy=18m8

19th August 2006, 12:35

bang on mate! might take you a couple of charges depending on how ggod you are and how good you want it too turn out but thats a spot on bit of kit mate!

2 year + bump woo.

Has anyone got any tips for boring out the throttle bodys?

Considering doing it myself

fit a bigger 1, hardly any material on to bore out.
