Well this friday im going to calder for the 1st time to test my car down the 1/4

Here are my setup:

14psi

Full 3" Straight through exhaust

GCG Highflow turbo

FMIC

Bosch pump

Dunlop sp 9000's 255 rear , 235 front

Rock hard height/dampening adjustable coilovers (dont know wat brand)

and im running a chipped ecu at 14psi, not sure what rwkw it has.

My problem is, on stock boost i can launch fine and quick with only "axle tramp" feels like its bunny hopping in 2nd then i regain traction,

Once i boosted it to 14psi i try to launch, pop the clutch at 3000rpm 1st gear is all wheel spin, 2nd gear is all wheel spin, 1/2 of 3rd gear is all wheel spin.

I realise now i have to slip my clutch till i feel complete traction, however im not sure what the correct launching RPM is. Is their anyway i can pop the clutch and still gain traction?

On a closed road at my farm i dragged my workmates stock wrx. He blew me away at the start as i was wheel spinning till i hit 3rd, then i caught up neck and neck just before the 1/4 ended, i cant do this at calder...any advice? Is my suspension too hard? Or should i simply slip the clutch ... its too hard to practice by myself as i cant test against another car and im back in the city.

Oh and when i did a granny launch like a normal start, he still; blew me away at the start and then in 2nd i was axle tramping again! like bunny hopping/wheel spinning...i cant stop it, 3rd gear is my strongest gear as i get full traction and the 14psi makes up for my lost wheel spinning time...but by then the 1/4 is over

Any advice would be much appreciated, so i can prepare for friday night :):)

Ide say alot of its your suspension/camber settings

get these in order and youll be able to put all the power to the ground

also, running a gcg hiflow at 1bar will be somewhere around 240rwkw, have u still got standard injectors? and if you havent got any dyno tuning done then your dis-advantaging yourself

Cheers for the replies, drag radials? i can get my hands on a set of mickey thompsons, well the guy at work said his mate runs a tyre business and hell lend me mickey thompsons, ive never heard of them in my life? are they drag radials?

I have also ordered a set of pineapples to be installed on friday, as i read in previous threads they reduce axel tramp

I still have standard injectors, and i did have a dyno tune when i had the stock fuel pump and the tuner entered in values for my High setting and Low setting but said he couldnt continue cause my stock fuel pump was weak and dying,

when i got my bosch fuel pump installed i ran the high setting and boost holds at 14.7 Psi or just under? It doesnt feel laggy and the spool is mega loud...am i running too much psi? i go through a whole tank of fuel in no time...its ****ed :)

I had severe axel tramp the same as what you are talking about.

I got some alloy rear subframe bushes (metal versions of the poly pineapples from whiteline) and it was a WORLD of difference. For ~$100 you will be very surprised the difference that they will make, especially for launching.

I installed them myself, all you need is a jack etc. and around an hour - there are HOWTO's on the web and other places.

    • 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.
