PassionFord Post Whore!!
my point was a tuner will in some cases tell you what suits them!!! christain is not a tuner and will only tell you what he has tried and tested and probably couldn't give a shit what box you fit to your car because your not handing him the readies.

I have read the whole thread and come to the conclusion from that thanks, christian is recknowned throughout the rst tuning world for what he has done but you bicker with him in my eyes that makes me think you are an idiot and are just JEALOUS of what he has achieved all he has done is try and help and give you reputable figures
there is no doubting christains ability at tuning a cvh and i an not questiong that?
if you feel that bickering with people and just excepting the someone word for it, then whats the point of having these threads? i thought i debate was jus that a DEBATE?

look morph , i read what you said regrads may eairler post
why dont you just post your spec ...... it may take away some of the doubters and would give you more credability in your attempt ,
dont get me wrong im not saying you aint credible ,i dont even know you fella,
but as with most things on here when someones attempting something , folk will always have there reservations untils you show you aint just talking shite,
+ id like to see what youve built fella,
btw means fuck all to me , my 450-500 rwd yb s1 will smash 170
even with a fat fucker like me in it ,

that is what christian stated to early in this thread:
It's MATHEMATICALLY impossible. Gears are FIXED items, you cannot alter the speed/rpm factor of a gearset (only alter rolling radius, of which there is only so far you can go in practical terms). All you can do is improve the engines ability to rev harder. Thats where it gets hard. Zetecs notoriously don't rev without spending money, then you'll need to get good power delivery so that you can actually hit 7500-8000rpm in top gear.
running 17" alloys with a 205/40 tyres on a st 170box you would have to have the shift point at 8000rpm to make 175mph, which for zetec or cvh is impossible to do!

Remember that half the point was that even if you could (hypothetically) make the Zetec or CVH reach 8000rpm, you still need a SHIT LOAD of power to accelerate fast enough to get to 8000rpm in SIXTH gear. It's all a balance, lots of power will fuck the early part up as you'll struggle for grip. However, if you run wide/sticky tyres to give the early grip, they will have too much drag, which will affect the speed.
There is SO SO much to this.

the zetec's make a lot more torque and pull right up to there limiters the one i tinker with pulls to its limiter and 154 so quick it'd give my 600 ninja a run for it's money and i'd love to get a smaller final drive in it and see if some of these records could be broken but as said above most top speed stuff is for bragging rights and we enjoy showing Ł100,000 motors up on the road with it's acceleration, but i'm sure once we nick a few of the other times i.e 1/4, 0-60, 0-100 then we might go for a top speed but i'm sure there's more r&d first

who said you cant rev a zetec to 8k?
a zetec can rev very high if built to do so.

out of interest christian what turbo's have /did you try on your 1.6 as i've just built a fresh cvh with steel bottom end with a decent head which on another engine produced over 360 but he was on a gt30 which i don't like the lag of and am aiming for a true 280bhp figue and would appreciate your or any of the big boys inputs on turbo's used am currently on a t34 that tony t used to own, thanks for any help, p.s going to put it through a focus rs box or the 6 speeder if i can find the right clutch/flywheel combo for normal money

im sure ill be corrected if im wrong ,
but the cvh being 8 valve genrally make there torque lower down the rev range where as the 16 valve zetec makes it higher ,
ie , if the same two 1600 cc engines ( a cvh and a zetec ) both had 200 hp its fair to say that the cvh could make 220 ft/lb of torque opposed to the zetec that made 180ft/lb torqe ,
now NONE OF THE NUMBERS ABOVE are true its just an EXAMPLE of putting it into laymans terms,
but do you get what im trying to say fella ??
your aim ( as with what other folk are trying to say ) is that your aim for a top speed run it to have that torque where its needed ,
so whilst yes the horsepower is important ,its going to be your torque curve that wins or looses it for you mate
hence why luca have 380 bhp , and you having 380 bhp is irrellavant ,
i feel ive explained this correctly ,
if anyone wants to agree or dispute this please do ?

surely a 6 speeder (even if it cant get to 180 like some people say) will ger there quicker because of that extra gear helping the acceleration.
so if identical cars (one with the 6 speeder (call him x) and one with a 5 speeder (call him y)) did a run, x may reach the speed of the y in less distance meaning x can keep his foot down for longer increasing the speed more until the braking point at which they both have to brake

i was inquiring about a st170 box becuase i did not want go with the mtx box due to cutting reasons. i will be ditching the bc box as i am fed up of the old rod secltors not doing a great job and the unreliabilty of the bc box.

i think someone pointed out early on in the thread that torque wasn't a vital part of it or something like that.

If your going for a st170 box then you need to be prepared to spend a fair chunk to get it installed.
Clutch and flywheel set up being one of the expenses along with shafts to suit.
The other option which is slightly cheaper would be Focus RS box but ive not looked at those ratios for a long time.
They key factor is going to be an engine which is knocking out 350+ and loves to rev

luke do you happen to know what clutch/flywheel is in your set up or did simon keep that to himself as thats my last stumbling block got my mounts, shafts, cables all taken care of but the cost of the clutch is daft as it is easily worn out and 600 to replace it if it gets damaged or can't take the heat so to speak is daft

I specced the clutch on mine, Simon runs a different type

costs of the flywheel and clutch are expensive and the whole job is of fitting the 6speed conversion. engine wise i could possibly have my current engine re-spec'd with right turbo and valve gear to possibly get 350bhp but if its not gonna hold together then i can't see the point in wasting a costly build? also is it possible to make the cvh head rev upto 7500rpm or is that the danger point of destruction?

You need to discuss this along with turbo spec with your tuner though.
