my block is getting work done atm, am using mahle pistons/standard rods,
i want a strong 200Torque at the flywheel,
so what cam etc do i need to get this level?
cheers andrew

 

Kent cvh34 if on a budget, standard ford cam or newmans spec cam if your feeling flush. Standard flywheel, stage 2 t2 turbo, grs or evivalent ic, uprated injectors (beige would be fine up this power) 044 pump

I would say the above cams because they will bring in the power early and hold a longer power band, other people may recomend some of the more lairy cams which push the power right up the rev range, they will give more bhp but have a smaller power band.

 

i was wondering about cams for mine too, thats a great bit of info mate

 

Cheers,

I put that info up as this was the spec of my fiesta many years ago when it was pushing this sort of power, but back then it was only running a pace dc/ic which was struggling with charge temps if under load for any length of time. I did however run a hybrid t2 and a standard cam, the car tailed off at arounf 6500 but the power was there really early in the revs and held it right through with loads of torque, well a fair bit for a 1.6 anyway.

I used the kent cvh34 on a 1.9 engine I built in an escort RST s2 which again was very similar to the standard cam in characteristics but everything was amplified, the cam itself has been designed by Ahmed Bayjoo for the purpose of giving more torque through out the rev range instead of a flat mid range and power top end. They are a very popular cam for stroker setups and zvh's for this reason.

I would however say that the cvh engine does love to rev so going for a high torque cam may not be best, if you are staying with the standard size turbo then it would be a good choice, but if you were to upgrade to the larger t3 then another cam spec me be required which will encourage the engine to flow and rev higher.

People like Christian Major, Project RS, Jamie Going, Sitech,Norris Motorsport etc etc are the people to speak to on this, I can only comment on what I have done myself but I am by no means a specialist in the cvh depart where as the above wrote the book.

Hope this helps

 

All you need is a Stage 2 T3 and a front mount intercooler for 200ftlb @ fly, rest of the engine can be stock

 

Without a live map, I pressume a chip module will have to be used, mine was using the ahmed Bayjoo chip with the boost set to 16psi, I had to use beiges as the blue's ran lean anything over 10psi (they may have been old)

I would think though the standard blue injectors would struggle on this application

The t3 is a great option for more power, but I still think if its drivability and torque you are after the hybrid fiesta turbo unit is the best performer, no lag and instant power.

Plus the t3 will require more expense, t3 manifold, reworked down pipe etc.

I suppose there are different way to go around it, both options will give the power but will peform differently, all depends on what you are after

 

If it's for a FRST yeah... he has 3 RS's..... dont know which one he's talking about! lol
I assumed an ERST?!

 

i was going by his sig and avatar so assumed it was for the fez,
but 3 rst's?

then I suppose he is not on a budget.

So throw my advise to the wind,

get your car over to Karl Norris, give him your credit card and I can guarantee you will receive a strong cvh with good torque and im guessing a good few ponies.lol

 

standard cam will be fine,

 

As Karlos and Raj have said mate,

I got 205ftlb @ 17.5 psi peak with a stock cam and a stage 2 t3. I personally don't agree with Raj that the CVH loves to rev, it might physically do it but you will make no power up there with a stock cam and head. i find power peaks at 4-5000 rpm then falls with this setup.

Might be better with EFI, if it is for the fez you will need some injectors and either a 195chip or a remap.

Rob,

 

Hello Rob

mine was a fiesta rsturbo, the standard cam seemed to have loads of mid range but did tail off with the t2, but I have been in other efi turbo's with the usual piper/kent cams and they seem to pull a lot better past the 5k mark than mine but they didnt have much mid range as mine.

I think mfi and efi do drive noticably different in the mid range, my escort felt like it was bogging slightly until it came on cam (mfi) was set up my msd running 14psi and will reckoned around the 180 bhp mark, god knows what torque.

Its on youtube if anyone wants to see a straight line burst up hill

Rob - you got a good bit of power from your motor (im guessing mfi) for that amount of boost, nice one

 

Good man, i see what you mean, perhaps with a different cam other than standard (as you said) the power wouldn't drop off so badly. The power was only 185brake which i think is a little low for the boost, torque was good thought. Thought it had a cam in it for the rr run but later turned out to be a shoddy cheap after market standard one.

Any how, should be a fair bit different when its back on the road, bigger turbo, cam, efi ectect.

Raj, i went on your website the other day, looks like a really well thought out site! much better than the majority of site doing similar stuff to you. Did you do it your self?

Rob,

 

Yea get the link up mate

 

IMO The power dropping off was not the cam, it was the T2

 

well as said for 200 you'll need a t3st2 and the cvh34 is much better than a standard cam spools just as quick but pulls so much stronger of all the cams to go with the little t3 this was my favorite good front mount and if it is in the fiesta i'd take it up to msd and tell them to ring it's neck, on another note the above with a hybrid t2 would give about 180/190 at a push but would feel better as lag will be almost gone and would feel more n/a than turbo'd i'd also like to see karlos's spec on a 50 shot of gas too as think it would make for a really quick 1/4 car for it's spec and probably quite quick to it's top speed

 

How do our CVH's handle NOS Ritchie, do you know?

 

not yet but got a full direct port kit in front of me waiting to go in for some trials just got to finish testing this other cam i've got to see what it can produce first then i'll test it but tim had no problems with it in his and simon has had some good results to

 

its in a fiesta rs turbo,
my own spec was
standard bottomend/head
cvh34 cam
701's
ofab/msd custom chip to meet my spec
cossie stg2/3 T3
grs intercooler

set up by nms or simon, then once its fully run in il be putting P8 on it,

all i want is a genuine 200 pound of Torque/power

 

you won't need the cossie turbo just a standard escort t3 but in stage 2 tune if that makes sense the cossie one will be more like a stage 3 escort item and would be well overkill and quite laggy for the power you'll have and will spoil the driveability your management is capable of doing all that is needed for 200bhp no need to get p8 just let stu map it

 

Ahhh!
So how does it work then, do you have it set to come on at a particular RPM/Boost, or on a button Fast and the Furious style?
If it's on demand then I guess you would have a seperate map for when your on NOS and it switches over?

Hmmm.... this could be fun!...... how much was your kit?
Couple that with a new GT2560R and things could get interesting for me! lol
