gwilkinson34 Posted April 26, 2010 Author Share Posted April 26, 2010 Wow some big discrepancies there...! 4.6 with 170rwkw (albeit in a 32 which is lighter) and only 5.75 with 265rwkw in a 34? A much heavier less powerful XR6T can easily do low 5s... I guess it all comes down to wheelspin in the skyline then...? What is the best way to get a 34 to hold traction? Suspension, tyres? I think i'll be running my rears down around 20psi when i get it back...

PM-R33 Posted April 26, 2010 Share Posted April 26, 2010 Soft spring rates, pineapples bushes set to maximum squat, zero negative camber or 1 degree postive camber if the car squats a lot (as it squats it will gain negative camber which in turn will return it to around zero), good tyres, not to low. With a setup like this (probably similar to what Paul had) is your best way for a good time. The problem is most of us know this, but don't actually do it and have low cars with aftermarket coilovers and average tyres Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5199742 Share on other sites More sharing options...

MBS206 Posted April 26, 2010 Share Posted April 26, 2010 Well I can get my tyres 0 - 100 in around 2 seconds... Unfortunately the car itself takes a fair bit longer... Even if I pull a perfect launch, I have a major issue of grabbing second and the car fries both rears... That's with 255 wide rears... And it also does it on semis...

gwilkinson34 Posted April 26, 2010 Author Share Posted April 26, 2010 an extra diff Sorry, had to say it I was actually planning on selling the GTT and getting a 34 GTR - was for sale for several months but there was no way I was getting what I wanted for it... and the changeover price for a good low km fairly stock 34 GTR was going to be well over 30 grand... Got advised by many people that it wasn't worth it, and that I wouldn't be satisfied with a stock GTR anyway. Then to modify it would cost twice as much as the GTT etc etc... Decided to stick with the GTT and do turbo etc so i guess i'll see what it's like at the end of the week when i get it back! Not like I'll probably ever have the chance to drive a 34 GTR to compare so I guess it probably doesn't matter! I went the larger .82 housing on the 3070 hoping the boost response would be a bit more linear, and less likely to fry the tyres when it came on compared to the .63... Hopefully I was right...

I think i'll be running my rears down around 20psi when i get it back... Those claimed 0-100 times for the xr6t would have been done by professionals who know how to launch that particular car when it was in testing, not your average joe. They also have a launch control system in them as well... Yes, tyres and suspension play a fairly big role when it comes to launching, but it mainly comes down to the driver.

You did choose right, the power is quite linear, when i had my 3076 it was a lot easier to get the power down than when i had a apexi ax53b70 p25 because the apexi was so responsive it would just fry tyres the second you applied throttle Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5199965 Share on other sites More sharing options...
eightsixboy Posted April 26, 2010 Share Posted April 26, 2010 The best i have done so far is a around 5.8, thats with 236 rwkw's and zero traction. The main prob is traction. I have been beating by a mates standard wrx because i had no traction through 1st or 2nd. I know have semi slicks but haven't tried them out yet. I'd say mid 4's if you are running decent rubber.

paulr33 Posted April 26, 2010 Share Posted April 26, 2010 if you are struggling for traction consider wider tyres - as wide as you can run cost effectively without scrubbing better tyres - cost = more grip usually, pzeros are ace, my best 0 too 100 was with them less pressure - 20psi for max grip - 40psi for normal drive and good economy pineapple / diff cradle kit - prevent tramping on the diff / hopping camber (make the wheels sit flat when you dump power, most will find inwards, reducing contact area) tune the boost curve to give best boost vs traction - ie AVCR with gearjudge Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5200023 Share on other sites More sharing options...
BXAFTW Posted April 26, 2010 Share Posted April 26, 2010 I guess you could always try not putting your foot to the floor in the 250kw+ Skyline and feeding it in..? Guess that can be a hard ask in the heat of the moment. Will have to see how i go next weekend i suppose...!I don't want to get beaten by a fairly standard skyline (or a bloody WRX) after spending the amount I just have for 250-300kw so i might just get some damn good tyres...! I guess your usual inner-city drag doesn't start off with a full on launch though anyway, it's usually the feel each other out through the first half of first, then once you both know you are going to go put the power down... Am I right to assume that in that situation the 250-300kw Skyline is going to leave the 200kw one, or the SS / XR8 / WRX in the dust (obviously that is then taking the launch out of it...)? ^ LOL Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5200024 Share on other sites More sharing options...
PM-R33 Posted April 26, 2010 Share Posted April 26, 2010 better tyres - cost = more grip usually, pzeros are ace, my best 0 too 100 was with themless pressure - 20psi for max grip - 40psi for normal drive and good economy So 20psi in street tyres is about the best for traction?

paulr33 Posted April 26, 2010 Share Posted April 26, 2010 yep will give you more traction vs them rock hard at 40psi mind you, they will wear lots quicker so dont leave them at 20psi all day and night otherwise you will eat them up Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5200066 Share on other sites More sharing options...
PM-R33 Posted April 26, 2010 Share Posted April 26, 2010 Hahaha yeah obviously. Might try them at 20psi and have a bit of practice launching to see how they hold up.

dave_rb20 Posted April 26, 2010 Share Posted April 26, 2010 Hahaha yeah obviously. Might try them at 20psi and have a bit of practice launching to see how they hold up. hey mate 20psi does indeed give noticably better traction but it's more for straight line stuff just be careful in particular with running taller profile tyres at that pressure, especially if you plan to corner hard/kick the back-end out.. when I was younger I was a passenger in a VN SS running low rear tyre pressures for grip and the tyre rolled off the rim. wasn't pretty. cheers, -dave Link to comment https://www.sau.com.au/forums/topic/317960-modified-skyline-0-100-times/page/2/#findComment-5200154 Share on other sites More sharing options...
PM-R33 Posted April 26, 2010 Share Posted April 26, 2010 (edited) Yeah definitely wouldn't be taking any high G corners with 20psi in them Like I said, wouldn't mind doing a bit of practice with launching. Definetely want to start getting the power down a lot better and earlier so semi slicks will definetely be on the agenda once mine are worn down.
