i installed my fmic a few weeks back , i was reading today about something that questioned my opinion.

my piping for the cooler didnt come with a nipple so i taped into the vacume hose off the bov and hooked it to that = now i was reading that it can cause spiking?

what exactly is happening when it spikes if it does ? and am i running a risk having it working off the bov vacume hose?

help would be appreciated thanks

what happened when i had mine setup like that, when i grabbed 4th gear accelerating hard at highway speed, it would jump up to about 14psi for just a second.

then i put the nipple off the stock piping into the pipe from the turbo to the cooler and that solved the problem.

iv been driving a lot and watching my gauge . i noticed that slowly increasin speed during boost it will reach aroun 8 psi . if im close to hitting boost and slam my foot down - she will go to 10 psi - and hold , thats my peak . mind you im running stage 1 mods - fmic , pod , turbo back exhaust - twin split dump pipe , stock boost .

im looking to get a boost controller soon . how high do you recon is safe to go on stock turbo?

hahah dodgy basturd :PPPP..

um might wanna fix that up man.. um, i got the nipple out of my kit, but could proabbly just steal antoehr, and get it welded onto corner of top pipe. i got mine done at TMR engines slacks creek for 50$ :spank: they did it while i waited in about 25 mins.

theres a thread in the forum with their contact details if ur in qld.

      r34's love to squeal

      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?

      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.
