hey fellas, i thought maybe some of u might be able to help me out here...

u can modify a car as much as you want but in all honesty, its your ability to drive that counts more than anything

my problem is that i cant seem to perfect my launch..so i was wodnering if anyone could give me some tips...usually i sit at about 2500 to 3000 and jus ease through the clutch, but i still get taken off the mark...eventually through 3-4 i can them most of the time but if i could jus master the start....

any advice?

i actually like a nice salad mayo sandwich, usually goes down and hits the spot nicely :whistling:

oh hang on, launch, hmmmm

anton sounds like you have the idea ... i would be more insisting on 2000 - 2500 rpm easing clutch out and gaining throttle as its coming out

a little wheel spin, or chirping of the tyres is fine ... just no major wheelspin.

its not as easy to launch as everyone thinks

unless u got an auto ... meh

Your avatar shows a R33, your sig shows "RB20DET" - so this might be of no use but...

My R33 (pretty much stock) launches best at about 4200rpms. Any lower, it bogs. Any higher, wheelspin to hell. But 4200 - I go off like a gunshot. It's very tricky (especially with a turbo), but once you find the sweet spot you're laughing!

Much easier if you get an aftermarket computer with launch control - you can preset the revs your engine holds at whilst you hold the throttle flat down, as soon as it detects any speed (cos you took your foot off the clutch) it goes bach to full...

I Have an R32GTSt. Mods are FMIC 3 inch turbo back eghaust, 12PSI Boost. I also have a semi button ceramic clutch. Launching was a hard task to perfect. Usually 3500 - 4000rpm for a "moderate" launch or a redline launch if out at the track and just ride it out.

For average day to day driving i usually take off at 1500rpm.

Hope this helps!

a little bit of wheelspin is better than bogging it down. i have a heavy single plate clutch and only have stock tyres (205's...i know they are crap, but my old ones weren't legal and i only paid $200 for 4 new tyres on stock r33 rims). putting 270 odd hp to the ground through them is rather tricky. i rev it up to about 3000-3500, load it up on the handbrake. then when you want to go you drop the handbrake, gas it as you let the cluth up quickly. use the accelerator to determine how much wheelspin you get.

Is the car in your avatar a GTR - or has it just been badged a GTR like some (i won't call anyone names) people do?

If so, up the anti and drop it from 3500 - 5500, that's the beauty about GTR's they stick, if not, 3000 - 4000 works for me.

Hmm Wheelspin... What if ur car is running on High Boost all the time??

how do u lessen as much wheelspin as possible

Sometimes i can smell clutch n it's burning or whatever

I rev it to about 1K or just a bit over.. Then Bang drop on the Gas

Still spins. Got 245'z Tyres, FMIC, 3 Inch Cat Back, Hks Filter n 9-10Psi of Boost. It doesn't get going till after 2nd... then goes all out once i reached 3rd..

It's a bit of a Problem when draggin other Fast Non-Turbo Cars.. aka V8's, SS, XR8 etc...

I rev till about 3000. Lift the bandbrake, let clutch out till the friction point and then release then hanbrake. I may not come onto boost as quick as the guys who drop and feather the clutch at 4000 but it's consistent.

Tyres and suspension play a monumental part aswell

Jeezus, this thread is filled with so much uncertainty that it's just not funny.

Few points for you to consider (for the drag strip of course):

A little wheel spin is better than bogging down.

Generally, this requires a little more revs, and easing the clutch out.

It is car dependant - therefore, you'll have to practice.

What I did before, was I would start at 3k rpm. I tried to pop it, it boged.

Popping it at 4 did a mini burnout, then bogged.

Therefore, for general semi quick launches, without absolutely killing the clutch, I just ease it out at about 4-4.5.

But hey, that's just how my car goes with my tyre, suspension, clutch, power delivery etc. Therefore, practice on your own car.

But the general principle is avoid bog, avoid burnout, a bit of wheels spin is ok e.g. 10% wheelspin.

hmm, when i had the stock 32 turbo, dropping it from about 2500 was the perfect launch. Now with the r34 turbo its impossible to take off. Wouldnt bother taking it to a strip, too hard to launch, id be looking at 15's.

I've tried riding it down from 4k, too much clutch burn, 3k, it bogs even if i let it slow or it wheel spins to the top and dropping it from everywhere means either bog or burn. I was driving my mates civic (91, twin carb, 1.6L), he was in my skyline, i was in front of him on take off for at least 50 meters, till spoolage and traction and lag fixed itself and the line overtook

Ok ill post a proper response about my experiences. In my old R33, it had turbo back exhaust, 10psi, Power FC, FMIC (191rwkw), rock hard tein susp, 5 puck brass button clutch, 255 wide K104 tyres, revs at 4200, drop clutch (foot flat all the way) & wheel spin half way through 1st, ran 13.5 @ 106 with 1.8 60’ (with granny shifted 3rd)

As adrian said, it's car dependant, so practice makes perfect.

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Mistakes were made, my R34 Story

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
