problem

[twoquik]

Can someone tell me what this sounds like?

situation is under throttle even if its full or half throttle

car appears to not go anywhere just as if the turbo is not working.

i can hear the car spool up though and the guage reads the right pressure.

it makes no differerance if i run 8 pound up to 13 pound.

only engine mods are

hks pod

blitz boost controller

stock turbo

stock cooler

where should i start looking?

could it be the spark plugs or coil packs?

or would it just be sometype of leak?

Thanks Guys

take the handbrake off!!

take the handbrake off!!

ha ha nice one! :Oops:

If you are on the throttle and you can hear the turbo spooling and you arent going anyway could be a slipping clutch?

Just a guess

[twoquik]

nah clutch is fine, and when i say not going anywhere i mean its just doesnt take off like it usually would. just seems like i am driving a n/a with a blow off valve lol.

[Jimbo2000]

either a leak somewhere or a busted turbo i think

Loose or broken intercooler hose

CAS? mine does this when its cold. I put it down to the CAS

[knore]

youve had a few problems lately ben?

have no idea on this one, check all the basics like hoses and connections, maybe bad fuel, need new filter?

[WazR32GTSt]

are you trying to say that upping the boost isn't giving an increase in power?

or are you saying that your car is slower than normal and its not boost related?

[twoquik]

its slower than normal. much much slower, like asif it was a n/a car

Loose or broken intercooler hose

yep yep yep yep.............I totally concur Inasnt!!!!!!!!

Mine gave the same effect regardless of boost pressure I manually dialled in.

It was found to be just a silly loose big hose clamp just prior to the plenumn.

Tightened her up and back to normal.

I feel your pain, but ur making boost (pre boost-gauge anyway...and that's all that matters!!!), it's just not being sent to the right location cause it's VENTING from somewhere to atmo!!!

You'll be fine! Just check everything (hoses/clamps) and don't take anything for granted.

.........unless ofcourse your turbo really is stuffed!!!

i had a simmillar problem a while ago, my car used to run like a complete dog, regardless of boost. happened a while after i had the timing belt done, turns out they stuffed the timing up a bit and made the car run like a pig... just one possible cause...

hmm but if the boost gauge is showing + boost then theres boost going in as the gauge is getting the reading i assume from the intake plenum so theres compressed air going in the plenum.

[knore]

hmm maybe youve lost a spark plug or two or failed coil pack, that would drastically affect perfomance

If you want, buy new plugs and come round ill help you put them in. Changed my plugs a few times now

Assuming it is spark plugs though, could be anything

[Timd]

Just reading your post again. Your prob sounds similar to mine.(see post in forced induction) making boost, reving out, no audible pinging etc. I replaced spark plugs bout a week ago, tested coil packs, fine. Ill let you know if i come up with something. Went to overtake a ute pulling a trailer today at 110, only just made it past :Oops: lol

nope......good point!!

But wouldn't the reading of the gauge depend on where it is tapped into?

ie: ......tapped straight into the plenumn, your point is true (plus you've blown my leaky hose bracket out of the water 'cause there are none left at this point)

But if ur gauge is tapped well prior to the plenumn (like mine is at present), chances are there could be a leak after the gauge tap.

BUT...aha...if you had 2 gauges (in the interim) you could 'narrow down' the vicinity of that leak!!(??????)

I'd bet that this skliner has got a gauge tapped well prior to the plenumn.(?) and therefore his gauge shows boost (it is there!!), but it's not going where it should.

It just doesn't sound like timing or plugs to me. (i'm sure he'd be 'complaining' differently if it was??)

ill have another good look tonight, and i will tell you were my guages are tapped into, i have one for my electronic boost controller that gives me a boost reading and another for the old school type gauge that also gives a reading, they always match also even since i have had the problem. but yeah i will let you guys know where bouts they are tapped into tomorow morn.

ill check all my clamps also but they seem all sweet, havent looked at the cooler pipes, but i only have a stock cooler.

maybe your cat is seriously blocked and f****d?

just an idea...

[cameron]

Have you fixed the problem ?

If you havn't I'd say its your timing, your crank angle sensor sounds like its been too far advanced thats why its making boost, reving and going no were. Try turning it back a little bit and see if it improves or get a timing light and set it back to standard.
