Hey, yeh pretty much all sorted now. Haven't had a compression test done but she makes around the 400hp mark now which is good. Been ages since I've posted in this thread, can't remember if I updated

I don't use the hand brake to launch so these are without handbrake

5500-6000rpm is minimum to get a good launch with stock turbos, 6500-7000 for -7s is what worked in the 34 so the guy ( sorry I forgot who it was ) that said 7000rpm for -9s is on the money, you just have to ride the clutch like you paid for the full hour and you intend on enjoying every minute

drive it like you stole it, service it like you love it

Well I've cranked my stockers up to 18 pounds not too long ago and it would've been the most violent thing I've ever driven....took some mates with and they too were very impressed! It was very, very troquey down low and pull all the way thru till redline in 1st and 2nd....but in the remaining gears they weren't too crash hot.

The only thing I've been wondering about is how yours fair down the straight in the higher gears?

124mph on GT-SSs ? I have run back to back 125+mph on stock turbos in a full weight car(+ 2 amps )so why would GT-SSs only run 124?

R33 GTR - heavier :D

Everyone i know with -9s hasn't run better than 124mph on PULP in a 33R

Oh actually 380rwkw man has a R32 so it would be higher by a few - but it still won't be anywhere near 130mph, which it will need to be to back 380rwkw

125mph over a standing 1/4 is how it goes in the taller gears :yes: , it has also seen 240kmph+ by the end of EC main straight,

ride clutch, it should be a progression not just a step, stepping will break drive line at 7000rpm, the key is to load the drive line then progressively lift foot off clutch pedal and hold on. :thumbsup:

are yes 33s are very fat, and I don't mean PHAT, lol :nyaanyaa: , even so given 125 with 290rwkw, a genuine 380rwkw I would think should see more then 130, then that's in a 32

      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?
