Why am I so bad at launching - Vids

Hiya all - I wasn't really the bothered about going to a drag strip at 1st but now I've done a couple I'm really starting to get into it.

However, even though my car is 325rwhp I still can't get get lower than a 13.9 @ 104. My 60ft time is normally a 2.4/5 sec which is crap so what am I doing wrong?

Here's a Vid of 4 launches from my last drag day. My slowest time is 1st through to my fastest being last.

Clicky Clicky for the Vid

I've got Launch Control fitted (thats the rev limiter sound on the vids) set at 3100rpm to stop wheel spin and prevent bogging down.

At the moment I haven't got any suspension mods (other than lowering springs) as I don't really know what would be best as I use my car everyday so it can't be too hard/soft etc.

Cheers....................................................IanH

Lower tyre pressure, better tyres, better rear suspension setup...these things usually lead to a better launch.

Also why dont you try and launch without traction control limiting your revs, will give you more control and more chance to find a perfect launch point.

Get a set of "pineapples" from "Dr_Drift" (or your local "Whiteline" workshop) on here. They will help the rear end squat better and put the power down smoother. I could notice the difference within the first 200m of driving (in a normal manner) on a public road after having these fitted. Will cost you about $180 fitted.

Launch control is a great idea but may i suggest learning how to get your car off the line without it first, then progressing through to using it once your 60' times are 2.2's at the slowest.

I remember driving my skyline on 11 psi, and I can tell you if I were driving a skyline on 1.2 bar I would be pulling at least flat 13's on my first go!!!

Easy to say, harder to do. Don't talk such total shit till you've done it and have the slips.

launching at 3100rpm? I believe you should be launching higher than that particularly if are you running a non-standard turbo and it takes a higher amount of revs to really get spooling. :cheers:

From your video it looks as though it takes quite a few meters for your car before it starts accelerating, it should be scrambling for grip from the get go.

Hope this helps.

Yeah, Adrians right, you should try and master launches without the launch control on first.. Remembering that you may not be able to go full throttle until you hit second gear.

Watching the vid, it seems as though it's bogging down on the launch, then breaking into wheelspin at which stage it's either bouncing off of the rev limiter or the launch control rev limiter is still activated. Then by the sounds of it your gear changes are a tad on the slow side.

Practice makes perfect, and you've done the right thing by asking for advice.

Oh, try dropping your tyre presure too, simple to do and it may help.

Even though my car is making under 200rwkw I find it will wheel spin if I bog the launch down, it appears if I launch it hard and load up the tyres then it won't wheel spin as much only chirping the tyres through the gear.

I've always thought of it as being similiar to slamming on the brakes and feeding on the brakes.

Have you tried doing a little burnout before the launch?

Tyres and shift with a little more vigour :cheers:

Im interested to hear about the launch control as well.

lol at 2rismo, your not exactly shy about telling ppl what you think of there comments. Who cares if he has never run the 1/4? Hes allowed to hazard a guess as to what time he may do.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
