Nigels Es Cos BOOST problem?? Help needed pleeease!
Nigel (Esconige) still has this running problem with his car, where the boost is very slow to build up.......It will peak eventually at only 26 LBS/PSI (should be nearer to 28-30 LBS/PSI.
He tried the bung/compressed air test at 30 PSI and it blew off a couple of hoses....so tightened all clips up.
So, with 30 PSI compressed air in the inlet, his standard dash boost guage is only reading 6 PSI...and when he turns ignition on the SECS monitor also shows only 6 PSI..........Soooo, could this be the problem??
Has he got a blockage or restriction somewhere???
ANY ideas/suggestions please?????

If with 30 psi in the inlet the secs thinks its six then it means the map sensor isnt working properly surely????
And if the map sensor is that far out, then both the fuelling and timing on the engine will be completely wrong.

doug chip means how do you seal the cylinders
thinking about it to test the hoses the throttle will need to be shut ?
with the throttle open are you saying niges boost gauge is under reading

MAP sensor on there is my working one, Well it should be 
We swapped the MAP sensors over and still no joy, but maybe mines faulty aswell.
Better fookin not be, its virtually brand new

when my mpa sensor went down the car was a absolut bag of wank! but it did c reate some lovely flames though!
but once u were over a certain psi it cleared itself!
if the MAP sensor is fooked the secs monitor should b displayin a random value when the caar is not runnin but igniton is on! @ least this is what my laptop diod in the escort!
i.e. with the ingtion on & the engine not runnin the lap top was sayin i was boosting @ 5psi! which i though was impressive!

Offered to look at this car twice FOC on other threads and been ignored.
I am local to the owner and know a bit about these cars despite what others think.
Oh well.....

Si am i right in thinkin if the MAP senspor is broke then with just the igniton on the monitor should read somethin random? like positive boost when the engine iant even runnin!?

In the end I never went to that meeting as I had no reason to go.

Simon,
Chill out, I remember your post and Nige did in fact reply to it THANKING you for your kind offer and hoped that you would be able to at some point. However, neither of you followed it up by the looks of it 
.
Anyway, you have more important things to do.
Did you get my emails - what do you think of the Ferrari job?

OK simon no i didnt say yes to your offer but i was expecting u to be there.sorry next time i will make it clear cheers for the offers si i would like to takeu up on it.Right the test was done throttle open and closed.the pipes are swelling with pressure and become hard like a errection yes doug lol but the gauges inside the car read a max of 6 psi but if i had the bung fly out then surly there is more than 6 psi in there.As for the valves basicaly there is no escape of air its all pressurised if i remove air line allte air will hiss back out at me ie there is defo pressure inthere and not escaping

Nigel, can you disconnect your dash boost guage and make a temporary connection DIRECT to the compressed air supply - regulated at say 28 PSI (2 BAR) and report on what the guage is showing???????

If not, then fair enough.........but he has 28 PSI compressed air injected in at the turbo, we presume the same 28 PSI in the intercooler and the same PSI in the plenium.......worth checking it through

I'd like to know what PSI you have in the plenium when 28 PSI is being fed to the turbo.......Because if there really is only 6 PSI in the plenium (with or without throttle open) then your inter-cooler or the hoses it and out of it must be badly blocked

Doug, just cause you are putting it in doesnt mean it is still the same at the other end.
Easiest way to test the map sensor surely is just to put 30 psi from the compressor straight into the map sensor and see what it reads?

Nige, Didnt mean it to sound like I was having a go - sorry !!!
Bad day - females
Anyway....
WARNING: More accurate test of the MAP sensor should be done BELOW 30 psi !!!!!
30 psi is far too close to the sensor limits.
I.E.
at 0 psi (no compressor),
at 10 psi, 15 psi, 20 psi, 25 psi
That will be sufficient to find 99% of faults with the sensor.
There will always be minor differences between an electronic read out and mechanical gauge no matter how accurate either is.

this was really baffeling to see!
the cold side samco was ballooning under the pressure of compressed air,
(plug put into the intercooler pipe) and yet the SECS AND ford gauge
Would NOT read over 6-7psi (1/2 bar on ford gauge)
Simon, your input IS appreciated! nige was at last bristol RSOC hoping you'd be able to have a look (even if he wont admit it! lol).

Right update ive changed the actuator and stillno diff checked to see if the penny wastegate was ok all fine.I also tried running her down the road with out the actuator puipe on and it did make better bost but still did seem laggy butthe boost was defo there lol.Im really lost for ideas now
