Is the LINK ECU setup to run your VCT???????

yeah as far as i know the vct is set to kick in at 3000rpm because at 2000rpm it was causing a slight throttle miss fire

i dont know much about the tune part :P

found out from tuner its from 3000 to 6000rpm

I cant really dump the exhaust and drive around the streets lol and booking into tuner takes forever he always 3-4weeks booked out.

went for another few test/runs last nite from 60-200 hard into 4th , boost drop off between gear changes is horrible it takes so long to build back up and start pulling

could 50mm gate cause this? being to large for the turbo setup?

I have driven around the block before without an exhaust just make sure its a short block hahaha. yes you get a few looks :)

in theory, yes. but we arent talking half the map worth of load dropping off, if the tune is good it would be lucky to lean out anywhere near whats called dangerous.

plus its only for a squirt, ud want to re dyno it after u fix the problem anyhow.

The way i look at it is if the rectriction is causing it to loose 50rwhp, then removing the restriction means there is 50 hp worth more air going through the motor with the same fuelling. 95% time it will be fine for a short squirt, but i wouldnt risk it without knowing whats going on.(but i have a wideband so i have no excuse)

i see your point adriano.

justin, i know disconnecting the VCT will make it slower but the point of the test is to see if the VCT is even working... if you disconnect the plug and it drives exactly the same, uv found a major contributor to the problem

also, going around the block for 1 little squirt in 2nd from a low speed just to see how boost builds wont get you in TOOOOO much trouble. just dont over do it.

this afternoon done a full compression test and came up even across all cyclinders so motor is still fine

tried a different bov nothing changed, tried no bov and nothing changed.

hmm

i might try the vct tnite? see how i go

little bit of a video from yesterday on a closed road

hard 2 see but can feel the lagg big time between gear changes

havent tried vct yet.. pulling turbo back off this morning and trying a new setup

another vid from other day on closed road

*Cough* *Cough* Restrictive Exhaust! :P

Driving around without an exhaust is no louder than most harleys. Do you have a mate that lives on a remote road? Go out there, drop the exhaust and go for a quick drive. As said previously just give it a quick squirt and see if it builds boost faster but dont overdo it.

man that kicks in late.... the power is there but its soo late....

seriously try the VCT asap, that seems more fundamental than the cat tho.. even tho the cat might be holding it back abit, for the thing to have nothing till after 5 is pretty rough..

if you havent started stripping it off already try the VCT man

its already been taken off this morning and sent back 2 do some research into it.

going hi mount setup now with different setup see how that goes!

So your going to put a new manifold on without finding the issue? Whats to say that will solve it?

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
