all feel free to slate them, but until you have tried one then you cant say anything. I have tried one and can definetly say that it feels better than before. A great modification for £26.

if you want to know if they are any good. have a word with wayne at chipwizards. the cars with them fitted ALLWAYS seem to get better bhp figures. they arn't just dremmeled. they are bored out to be a minimum measurement all the way through. Feel free to butcher it yourself. but before you do, make sure you got a steady hand because one slip and you take to much off, hit an air pocket in the casting or score the seal. then you get an idle of 3000rpm (ish)... new thorttlebody on the way!

i dont mean to be a skeptic but 1.2bhp aint alot considering on the same car you get differences of upto 1bhp per run.

Its fair enough i can see how it would work on a engine with other modifications, if done after,exhaust,cam,enclosed induction etc i can see how you could get a good gain for £26.

For £26 how are you doing it? dremel? lathe? milling machine?

havent had a look at the vtr throttle bodie, but most bike carbs are bored out on a lathe.

im am fitting a clip 172 TB to mine, just waiting on some hosing coming then i'll be fitting it, thats over 10mm bigger than standard vts TB.

and the reason you'll be getting a better throttle response is, because if you look at the standard TB it is shaped to give a smoother throttle making the car more driveable at slow speeds and in traffic etc, this will be taking away when its 'ported and polished'.

i done my clio and vts TB with an air powered dremel style tool and dont see what the hard part about doing it is???

williamsvts · 22nd February 2009, 22:31

clio 172 TB on saxo vts plenum

de4n0 · 22nd February 2009, 22:46

did that make any noticable differences?

Sean_VTS^p · 22nd February 2009, 22:50

^^^^^^thats impressive.........scrap yard or expensive? lol st8 fit mate?

JamesR^m · 22nd February 2009, 22:56

it honestly does make a difference, many people including myself can back it up!

when people come on here and ask what performance mods they can start off with, this shuld be there along with induction and exhaust etc

got clio TB from cliowilliams owners club for £35, then made the bits myself to make t fit. have put it on the car yet as im waiting on a couple bits coming. should have it ready to fit tomorrow, i hope.
have a look in my progress thread for how i've made it fit and the bits ive needed.
cost me £50 all in, i got catch tank free and done all the work myself though.

Quality mate, maybe worth doing that instead then for the little extra it cost! Also if uve got how u did it in your progress sure it will help people out. Definatly something worth looking into! Thats when i get round to getting my tb out!

definitely interested to see the results of the clio tb once it's fitted. how difficult was it to make fit?

think most are being done on a milling machine not by hand with a dremel and at the end of the daty 1.2 bhp is better than no etra bhp and it all adds up.

Have to agree and for £26, who cares? and the Throtle response is also worth the money alone.

you'll need access to a milling machine or know someone that has to be able to do it.
i dont see why you need a miller to port and polish a standard 1 though, even when you port and polish standard TB, the diameter hole the air goes through is still the same size.

just like when you gasflow/ port polish a cylionder head ay? you dont make put bigger valves in but you still get gains!

tell me if im wrong!

JamesR^m · 23rd February 2009, 10:05

Spencer i swear by the serivce you provide, its top notch and cant fault it.

like most people i was a bit weary and thought that it wouldnt work but i am genuainly impressed with the results and reccomend it to anyone and eveyone.
