Replied to post in tech

 

thanks for that jon i did suspect that but trying ta kid my self as thats another Ł200 ive got to find but if thats what it is ill have to do it any way thanks for your help

 

just spoke to a friend has got a piper cam i can have with about 2000 miles on it will fit and see if it is any better as i have a sx428t cam in at the mo and want another one of those cams as i have been told the piper cams can make the car lagey dont know how true this is but im sure ill find out

 

speaking of cams , what rev range is the cvh35 best at ?

 

think its 2k to 7k its a bit slow to kick in but thats prob due to other mods as well but makes it pull like a train shame mines worn now going back to std cam..

 

Mine does this and ive just fitted a new std cam

Im thinking my turbo to metering head hose is collapsing under load??

as its ok if i dont give it full throttle worth thinking about.?

 

i have all silicone hoses would they still colapse?

 

i seem to have the same problem with mine, dont think its the cam! mine is new, got samco's, Could it be the actuator or the amal valve maybe?

 

i have the same problem some times it seems as the turbo doesent want to spin up.im hoping that new hoses will sort it as it is going in ea for a set up saturday

 

I had a problem with the standard boost hose collapsing, normally at high revs (5K+).

Sussed it out on the rolling road with one of the guys holding it while they ran the car up

Silicone has solved it

Cheers,
Marc.

Incidentally i replaced my cam last year with a Kent CVH35 and i think i prefer my old 90 thousand mile standard jobbie...
Seem to have to ring its neck a lot more nowadays for the same effect, standard cam has much more midrange (Useful)...

 

i have another small pob it might be linked, when u switch of engine it will shut down then about 3 seconds later will pop out of the exhaust i have been told that it could be leaking injecters if so could they not be faulty and spraying incorrect patern.ithink ill have to spend weekend swapping and changing bits around and see if i can solve it that way trial and error and thats long

 

ive got "EXACTLY" the same problem mate i was thinking it might be a ECU problem if i bring the power on slowly it seems to go better than when i just floor it duz your's do this to???? let us know how you get on with it

 

yeh mate thats the same as mine starting to realy piss me off
ive got a spare chipped and non chipped ecu ill try that first as its prittey easy but i plan to change injecters metering head ecu and cam 1 by 1 at the weekend as ive got all that spare and its got to be one of them ill let u know how i get on cus im desperate to get it back to the flyin machine she is

 

i dont think it would be the cam as i had a new one not that long ago i think it's a fuel side problem let us know how you get on mate as it would be nice to get this fooking problem sorted as it's REALY PISSIN me off to

 

Sounds like most need to get to a tuner and have their timing checked to me!

pop from the exhuast is always a indication

 

cannot beleve it !changed the spark plugs and the car is ten times better still not 100 % but a great impovement have got a set of new injecters coming as spoke to a guy he told me that i should realy put a set of injecters in it as they arnt that good after about 60,000 miles and i dont now how old the ones in my car are ,i have tried pushing the plunger on the metering head and it seems to have a bit of pressure when pushed down so ill change the injecters any way as thats another new part and eliminates them got them from euro car parts Ł80 trade witch ant to bad thanks for your help

 

i have the same problem with my escort turbo as antony215 what can it be it really is a shitter

 

My mates van had the exact same problem till today when another mate of mine who works for ford fixed it... the timing on the distributor was out. If you havent cheked that already it would be the first thing i would do

 

alright i will check that pal
but mine boosts sometime its when it starts to get warm that it doesnt much

 

ive solved my problem today, i seemed to have the same problem with the boost and it boggin down , ive just replaced the actuator and adjusted it up, now i cant keep the car in a straight line!

 

I recon its the actuator on mine also ...but found a guy who can make a metal turbo to metering head pipe..i have samcos but there well old..

 

How can u set that side up?

 

will mine be the smae problem mine seems to do it when it starts to get warm

 

you need a timing strobe done mine today run's ALOT!!! better now

 

Timing then, thought so

 

will mine be the same then it happens more when it gets warm

 

yep all the fucking about i done wish i checked that first

 

check your timing mate might be the problem mine was way out you need a timing strobe to do it if you dont know how to do it best to take it to a garage

 

always check the easiest and cheapest things first!

 

my turbo is still got loads of turbo lag think i need to take it to a specialist

 

help

 

Did you get your timing checked???????

 

anyone no any good tunning places in the north west for my escort turbo and its turbo lag

 

ttt

 

Anyone else fixed there problem regarding boost hold back

 

well mines not boosting atall, unless im not in gear and just revving it(well the dumpvalve works then.)

ive been told its the actuator, my question is, what actuator does a standard rs turbo have?
