I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
:brickwall::brickwall::brickwall: :badone:
Ok... i am willing to pay someone there travel expenses to come to me... and if they fix my boost probem then I will give £100 ....
basic story....
car has been like this for 2 years... i cant take this crap no more.. :P
i have a boost fluctuation problem. Say if i try to run 16psi, boost will spike to18 then go down to say 11*variable.... then slowly rise back up and try to get to 16 except by then i have to change gear so wont reach 16 (my desired boost) I can feel the obvious power loss.
pls refer to my profile pics to see my setup.
I have tried lots of things im nearly out of ideas (expect 1 but dont think thats it)
-changed all main boost pipes (except the one from bottom of charge cooler to turbo..but checked that)
-changed all the vacuum to 6mm or 3mm *tried both
-took my dumpvalve away from the equation
- taken any bleed valve off... vacuum pipe is now running direct from actuator to either carb top or base *tried both
-even tried changing carb... which i think is unecessary.
Is anyone willing to come down and try to fx...?? as i sed they will get £100 to solve.. im even thinkin more... all i want is my car to run at a stable-ish boost (even if it has a 2psi spike i dont care as long as it sits stable)

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
oh and have tried different turbos.....
last thing i will check is to run it straight wivout any from of intercoolers for a test run... but im sure that i tried it ages ago.. and no joy.. but il try it again to make sure..

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
is your actuator dying? have u tried another? i can post one down if you need a std one to try out
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
ah just read the tried different turbo's bit.... :cartman:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Have you got a split or crack in carb top?

that would be my first thought too :agree:

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
what size is your air ffilter hose?
i can lend you the best tool in the world for finding boost problems if you like.
i made a tool that you connect to the air filter hose and to an airline so you can pump they system up and find leaks.
you need a compressor and a tyre gauge tho.
i used it on mine and found i had 4 leaks on a new engine with all new hoses and everything,
it wouldnt go over 1.5bar boostt, once i fixed the leaks it went straight up to and held 3 bar.
youd be amazed how many you will have.
also got a -31 actuator you can borrow if you like?

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
leaky intercooler...?
check gaskets and black spacer at bottom of carb...?
Check carb top for splits or holes...

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
sorry m8 i dont have a pic, and ive lent it to a m8 with troubles on his cossie.
its very simple but a huge help.
it turned out i had 2 leaks on my fuel pressure regulator and a leak on each charge cooler, but i had new coolers, new pipes, new clips and couldnt hear/feel any leaks.
after testing the car was a lot more responsive and could hold more boost.
sounds like the OP definately has a leak to me.

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
a mate of mine a had a similar piece of kit for his audi s2. - it consisted of two large nylon/delrin bungs with a valve in one end, so you could pump up the boost system.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
you dont need 2 bungs.
if you pump it up from the air filter it will turn the engine over till it shuts all the valves, then it will test everywhere including the inlet manifold.
doesnt matter whether the TB is open or closed either.

Sorry fot the question: what is TB?

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Throtle Bodies at a guess
I made one of these testers too. Piece of samco hose blocked one end with an old spray can and put a tyre valve in the side and then used my tyre pump to pressurise the system. A very good idea.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
I made mine with a wastepipe rodding access, then the top can b unscrewed and different fittings screwed on. Then drill the cap out, fit a tyre valve and silicone it in place.
Pump up on an airline to just over what boost pressure you want to run.
As said I pumped mine to 3 bar and it held pressure fine.
And yes tb is throttle body.

And you feed it with the pump from the telefon hose? Or right after the turbo?

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Sell the car then the problem has gone, then buy another one without the problem, problem solved, how do i let you know where to send the money. :D
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
i would love to get another one and js put some of my parts into it...thats wat i want to do but i cant afford it right now.
Is no one willing to come down?? ok... £150 pounds.??? not going more than that tho
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
As I said on mine I removed the air filter and put my tester there, that way it tests the turbo seal all the way to the valves.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Where are you? Can the car b driven?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
im willing to help andyone find the prob (would be best anyway cos i know wats been done and wat not)
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
wat would it matter wat size air filter hose i have!?! even if i had no air filter it shouldnt have a problem..
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
I'm reluctant to come round and help as it sounds like it has a few probs and I don't wanna get blamed for any thing that goes wrong.
But I will let you borrow my pressure tester to try yourself.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Lol I wanted to know what size the pipe from air filter to turbo is so I know what size tester you need lol.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
lol.. why would you be reluctant? do you know 5 gtts well?? if you do..shouldnt be a problem cos il know what your doing anyway.. and im not gna blame you wiv any problems that are not related!! there are no probs right now (other than the boost) but its just i dont wana go too far out as yesterday was my first day. and i had a few teathing probs..
but fair enuf if you dont wna.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
but i wouldnt know how this tester works!! where abouts are you mate?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Tester sounds pretty easy to use. Put in over the air filter hose, connect to an air source (air compressor) and release air, use your hand over the engine and find any air leaks which are happening, might actually create one myself as that seems like an excellent way of finding out air leaks. Guessing an air compressor as that would have a constant flow of air rather than using a hand/foot pump which wont be constant.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
I'm in Croydon and I know a little bit about cars in general lol ;)
the testers self explanitory, plug it in, fill it with air from a tyre gauge and listen/feel for leaks.
They are quite obvious wham testing like that.
I fixed 2 of my leaks by just addin an extra jubilee clip, so make sure you have a few extra boost clips knocking around.
I wouldn't like to come round fix a leak then go up the road and find it's got 3 bar boost, an oil leak and a dodgy headgasket then I look bad when it goes pop lol
I'm not sayin this will hapen And not a dig at you but I've had bad experiences helpin others in the past.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
It goes in the filter hose, like the metal trumpet of an air filter would.
And it needs an airline on a compressor, hand/foot pump won't work.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
hmmm is there any chance u can post it.. (i will pay pnp)
whats this tyre gauge i need? ( wat it does and where can i get one)... im guessing its just to connect to your device and just pump wiv air?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
oh.. can it be anything to do wiv valve clearances??? or inlet manifold?? (not that i can hear any leaks)
also on the top of the carb.. pipe go somewhere(im told to servo) and im sure one goes to dash boost gauge (oe).. can i disconnect all this???/
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Tyre gauge as in to fill your tyres up with air, could always go to a petrol station if you don't have 1 or no compressor.
As for postin it I could but with royal mail as they are it could take forever to get to you, I could dhl it but unsure what if would cost. It weighs nothing but would have to go in a box so it doesn't get broken.
What's your address?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
ive got a compressor already
do u think i can make one?
do u know roughly how much it'l be to send?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
You can, it's probably easier than sending you mine.
Get to a plumbing/diy shop, you want a 2"/55mm rodding access for waste pipe
then get a tyre valve from a tyre shop, drill a hole in the cap so the valve fits in there tightly, then load the end of the valve up with silicone and pull it through.
Wait till the next day before you use it so the silicone has a chance to dry.
If the 55mm fitting isn't quite enough to fill the hose the use ductape or a silicone hose as a packer and put it where the air filter normally goes.
I would leave everything connected to the boost system that the car will run when it's fixed and test the lot.
You can use your boost gauge to see how much pressure your putting in. (might need to pull it out the dash and connect it to a short bit of pipe in the engine bay so you can see it)
but don't over pressurise it or you could pop a seal. Only go a few psi over what you intend to run so if you wanna run 18 then test to 20psi...

Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Slim have you changed the actuator for a known working one with a good spring ?
I've just called marky mark and theres a chance he may well be able to come over to you tonight about 7 or so possible is the engine aboe to be lit up ?
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
"possible is the engine aboe to be lit up" sorry wat does that mean??
ye changed the actuator countless times wiv different turbos... think i got a -31 on it now.. not sure.. but ur welcome to come n have a butchers :scratch:
tnite..im gna try changing carb top (although mine is the metal one from gt tuning) and disconect charge cooler from boost circuit... if anyone wants to come round js contact me on my mobi 07514 706 724.. im goin out now for a bit but bak in a short while :cooter:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
i can get light if needed..
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Colin/Master isn't that far from you. Might be worth dropping him a PM & see if he can come to your rescue.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Yep was ment to say can the engine bay be lit up ie it gets dark in the eve
I've given mark your number so he will most likly give you a bell shortly :agree:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
ye unfortunatly colin is 'out of order' .... :( think hes fecked his wrist up somehow :disagree:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
I know what the problem is :D
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
ok thanks banana man, il try that...come to think of ive got an re209 (phase 2- aei) on there atm but still located on top of the turbo, but also im not sure if i had the same problem with the phase 1 aei, but i think i did... il report back peeps :dearme:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
to find the leaks with the system pressurised mix some fairy liquid in water and paint onto joins with a brush. It foams up if there is an air leak.
I would start at the carb top and move back through the boost circuit.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
ok... wasnt the aei.... could it be inlet manifold wivout me noticing?? im normally good at hearing noises :rolleyes:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
its A Boost Leak Somewhere
get The Tester Made And Stick It On.

:agree: or actuator set up problem but stu's on the right line i recon.
Sorry didn;t text you slim mate last night, was late back so didn;t get time to come round.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
Yeah it could but he said he's tried 2 turbos and 2 actuators and has a new -31 on there I'd put money on it being a boost leak.
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
On the subject of boost...
Ive got a t28 fitted, with a -31 actuator, yet I can't get anything above 9-10psi above manifold pressure.
If I slip a bleed valve on, its fine, boost to where I want.
I dont want the bleed valve in place, so how can I increase the boost further ? :ashamed:
-
Re: I'LL GIVE £100 to anyone who can sort me ongoing boost problem..
-31 normally holds about 12psi spooky - make sure the preload is ok - normally you need to pull the rod about "half a hole"'s worth to hook it onto the wastegate. if it looks OK, trying shortening the rod and see how that goes.
