right please only reply if you no the problem .right her goes
1 2wd cossy full engine rebuild top 2 bottom and a hybrid t34 brand new 4x4 intercooler and dark greens 3 bar chip 044 fuel pump new magnacore lead champion QC59C new map sensor new charge temp(brown) new phase sensor new crank pick up sensor new cap and rottor arm new group a coil its all been run in and set up perfect runs 1.5 bar holds 1.4 NOW problem i put my foot down i boost up alright it just feels like its holding back befor i would just burst into revs BUT now it takes its time going up and feels shit ive got to pump the clutch to get it to even arse out even in the wet were as befor it would just step out all overthe place in the dry so now iam stuck were do i look ither way i now that i should take it to a rolling road dignostics but ive done all the work my self and it been good as gold every since trhe most recent thing that i have changed is the clutch . i also changed the live wire that goes to the coil as it was badly broke up so replaced it all the from the ignition switch ...
if ther any thing that i have over looked then plesae let me no

 

plugs gapped?
cam timing?
fuel pressure too low?
HT leads not breaking down?
Got a good connection on the blue plug at the back of the head?
Headgasket? done a compression test

So it revs freely unloaded but not loaded

 

do you mean its gone really laggy or its not revving quickly?

 

personally I wouldn't put Champion plugs in my lawn mower.

Start with obvious stuff if only to eliminate any doubts.

 

...always change the plugs first as this is the most common problem...paticualary the champions..utter shite imo..just binned the set in my 3dr as it was misfiring all over the place...put in the 071's and hey presto fooking lovely!

 

ive changed the plugs firts but ther was no cahnge then leads the cheacked timming its spot on and all plug gaps are perfect the conection on the sensor at the back on the head wich is the blue one its pluged in and i cant fault it fuel presure is a littel high ive turn it down and turnned it up with no differnce i changed the leads and still no differnce . it dont misfire it just feels like it tugs in and rather than pull clean right up as soon as it starts pulling it sort off feels like as if the timming is not advancing it feels as if the timming is retarded just flat the boost is siting at 1.4 and holding but ther car feels like its runnig 1 bar if not less

 

Checked the base CO setting? (Assuming it is on a non lambda ecu)

 

Does it smoke when you are accelerating hard?

 

it feels odd when you run 2 bar of boost and then you turn it down to 1 bar its not gone be as fast that what it feels like but my boost is still reading the same any .tips

 

no not one bit

 

Phil, i havent but that was not tmperd with sice the set up its a l6 ecu

 

you say you changed the plugs but have you put champions back in or id you reolace the champs with something else?

 

Moose 130, i have put new champions back in but thats what i took out it does feel like a ignition problem

 

i suspect boost leak. have a leak down test done. do you run a dump valve, as that is th emost likely culprit.

 

I'll agree with Moose...you're better off using the box the Ch***** plugs come in than using whats in the box

I'd also suggest veryfying your cam timing

 

EscortWRC, ive cheaked it like 5 times all looks spot on the 2 arrow looking thing on both cam pullys facing each other dead on and piston at its highest point and the rotor arm is in line with rim mark all spot on

 

foreigneRS, ive blanked off the dumpvalve and still the same

 

some one must off hade the same problem it just feels flat like its not realy running much boost but boost is the same . if i hade a boost leak it wouldent hold the boost but it still holds the same boost

 

UP YOU GO

 

the bolts were loose on my 2wd manifold where the two pieces join and that gave the same symptoms, made the same boost just was very lazy in doin it

 

the strut brace, what bolts you on about

 

the2wd manifold is in two parts yeah! its where the 2 parts join with the 4 bolts, 1 had snapped and the others were not that tight so looked ok but when you got a hold of the turbo without the damper on there was slight movement in it and then i noticed the bolts etc , any crack/gap/loose bolt makes the fooka lazy and the boost takes longer to come on etc, check all your nuts on your manifold are tight and your manifold bolts too!

 

the strut brace, ther all very tight as ive checked them plus the tutrbo is new its feels like its just on the verage off pulling realy hard but it dont its running 1.5 bar but feels like its runnig 1 bar but boost comes in gradgually befor it would gust snap in to revs the boost would gust be ther rather that have to wait for boost to build up

 

Have you checked what sort of rpm the boost is kicking in?!

 

Toe Knee, turbo come in as normal about 3.500 rpm its a t34 with a 48 housing

 

No problem.....just seemed logical to me...if its spot on you have one less variable to consider.

I can't think of what else would make it do what you describe....but if I do, I'll post again

 

are you running a amal valve ? had a simlar problem and ended up being somthing to do with the jetting ???? may help if not forget i spoke

 

EscortWRC, start thinking m8 but thanks need more advice

 

neil d, the jets have all been taken out and was mapped that way

 

how about actuator as mine is almost run out off threads is that how ther soposed to be or is mine fucked and over adjusted as a result of it being no good

 

Could it be you are just getting used to the power?

 

abdr500, if the actuater is almost gone m8.. ide check that out.. im no expert in these matters, but if something is almost knackerd.. then its most likly the culprit.. sorry that im no use..

 

just take it AVA and they will fix it!

 

Put the satandard leads back on

 

so....if the boost is holding and flies up as it should, then there is no actuator problem
you have checked the ignition and metered out all the sensors, i am guessing
and you have checked the cam timing/condition properly , the engine is quiete at the top end and not making any untoward noises, the engine is not breathing heavy or blowing oil seals out or nothing stupid
the brakes are not getting hot , you have jacked the car up and checked the diff is spinning as it should, and the g/box and diff are not making any strange noises, you have good oil pressure

several things i have found on mates cars with probs

2wd manifold leaking on gasket....
2wd manifold leaking on turbo to exst manifold connector....bolts had come loose(the four expensive ones that 2 are upside down)
blue coolant sensor failed
map sensor broke
coil..low tension connector corroded away
phase sensor fooked
cps fooked
mate forgot to seal t34 lambda sensor hole correctly
compressor hsg seal leaking
intercooler had a crack in it
cracked block
valves not seating correctly

without seeing the car , 99% of people can only guess, i don't mind taking a look for you but your better off to take it to a specialist to be fair


HTH
pugo

 

Long way from Enfield

 

thanks every one i think i have sorted out the problem

 

pugo, low tension wire were does it run to does it go back to the ecu

 

not true. it would try to make the same boost as the actuator would hold the wastegate closed until it did, but it would be doing it at a higher turbo shaft speed which is inefficient.

glad you've got it sorted, what was wrong?

 

feck never saw that thought abr500 was aberdeen500?
im daft!
