hmmm i dont know why pplz do all sort of stuff to there cars like puting the boost up if ya gonna lose to a excel off the line. Thats hitting rock bottom. Gts-t's even in stock form like full stock form, can rip most cars off the line. I understand by putting a bigger and better exhuast and better air intake mods the car will have more power, but whats the point of having XXX RWKW's if its not properly tuned? so many cars i see now on the roads that on paper looks very intimidating, but on the road dont perform all that great. (And in many cases worse off than a stock version) Is a waste of time (And money) if ya dont know what ya doin. Anyways i thought id add my 2c worth.

Putting the boost up won't make you slower off the line, but I hear what your saying. If you make bad decisions when doing mods, they can have a negative effect to performance.

Filter, zorst and boost mods should not have any negative effect on off the line performance, other than maybe excessive wheelspin :spank:

Okay maybe I didn't explain myself. The initial launch off the line. eg the first second. heh no way do they compare at all. And yes I can still beat the wrx's i've come across in the long run say over say 0-80 although right off the line for the first second or so you can't just compare to dumping the clutch.

Do you stall it up by holding your foot on the brake while puting your foot down on the accelerometer? Do that until the wheels just start to spin gentaly. When the lights go green, plant it and take the foot of the brake simultaniously. It takes a while to get it right, just like in a manual (but easier to do consistantly). To much stall can create to much wheel spin, not enough can bog down. You will launch INSTANLY by using this meathod. No 1 second bog down. You know when you have done it exactly right because you will slightly wheelspin for about 3-4 metres (not enough to get smoke)

Ok, took the auto skyline to the track last night. Mods include pod filter, 3inch tbo back zorst, ARC front mount using standard cooler pipes, dual stage boost controller set to 12psi.

1st pass 14.47 @ 96mph

2nd pass 14.31 @ 98mph

Both 60ft were 2.254. If i had more time, i reckon i could of cracked a flat 14. Will keep you all updated. Any one else with auto 1/4mile times on auto skylines please post as i will be interested. Also i hope to get the car on a dyno soon too.

That's some bloody good times keep up the good work.

I haven't done any engine mods to my Auto Sky as yet doing all the suspension first then I'll move into the engine bay.

The closest 1/4 mile track to me is about 400k away and I think the closest dyno is about 300k away, ;)

Well.. stall it up to 2k then just launch. It has more in it. I can feel it. Also hit rev limiter on both runs in 2nd gear, my bad. After i take off, once the revs get to 5k it wheel spins again to rev limiter. The main thing the cooler did was give me abit more top end, some lag and also more safe to run 12psi.

Usually on hardgrave road in west end, I see it when I go to work most days. It looks very similar to the one in your avatar, just thought it might be yours (I would have told you to park it in a garage! Not real safe out there imo).

Took the car out to willowbank again tonight. This time we fitted a new aftermarket dump pipe to it. We ran a 14.1 @ 99mph with a 2.2 60ft. Track temp was at 30 degrees. If we waited abit longer i reckon we could of dipped into the 13s.

Edge - I have a Series 2 GTST auto and ive got her upto 245km/h b4 i had to slow down for a corner so she may have had more, If you get a cut out at 190 its because you have your O/D OFF, turn you O/D on and you will get to 245+ on an open road.

Im wondering if anyone here has an auto gtst with similar mods to mine so i'll know roughly how much rwkw i'll get when tuned up again ..

Apexi Pod

S-AFC

12 psi Boost

Cat Back Exhaust

HKS Front Mount

NGK Vgroove's 0.8gap

ive gotta auto r33 gts-t ,with a 2.5inch rear muffler,fmic pod it dynoed 158rwkw.The exhaust is really holding it back to the point that every 1 psi drop's 8/9 hp !!And with a Safc it couldnt make ne more power.I found out it had a melted cat aswell .But it still doesnt seem to make good power for a r33 .But off the mark its a rocket good old snow button.And before u say its bad to use the snow button,I hate auto and if i brake it then my dad will put a manual in :D

Oh thats more than i got on my last dyno run .. yer im ashamed to admit it but i only got a shity 152rwkw, but i only had the stock cooler then ... and tat was at 12psi but the plugs were gapped at 1.1 at the time so it detionated hard on the way home, but im not sure that if i had a .8 gap then that it would have given me a few more rwkw's ..

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
