So after fixing my problem with the car i got the car on the dyno again lastnite. (hose clamps and hoses)

post-31456-1166491844.jpg

still getting my loss up top. and worse when i have the old profec a boost controler on it which i think is just a problem all together.. this run was with a bleed valve..

now the loss i am getting up top could be from my plugs which i need to change as there is a miss fire up top.

but when on stock boost the run is very smooth power is a nice curve with no problem and boost is a very flat line. only when boost is up it does crazy things up top.

my standard dumps are probably causing some backpressure up top and could be adding to the problem.

p.s. car was run in 5th gear. not 4th like graph says!

afr is up the shitter too starts up at 14ish then goes off the scale below 10..[

i think they can? its only about 1.5ish bar right?

so i think i'm going to drop the engine out. maybe over xmas or something.

change timing belt, plugs, fix seal around front diff, check out what rod's or rod bolts i have, fit the new dumps. and if i can get a new boost controler i might give that a go.

then a definate tune is needed with my afr's haha

      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.

      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?
