Hi guys,

I'm putting my car in the Warrnambol drags on Feb 8th, and was after a few tips from those who have dragged before (rpm launch?, etc)... Was also after a rough estimate on what time I should get, here's what I've got;

95 R33 GTST

FMIC

3" Full turbo-back exhaust (heat wrapped)

boost controller will be set to 15psi

loaning a set of 17" semi-slicks for the day

stnd suspension

k&n panel filter

Will also have new Apexi SAFC & bov by then too. Car will be dyno'd and tuned.

after a few tips from those who have dragged before (rpm lunch?, etc)....

I suggest about 5000-5500rpm and slip it off the line with a little controlled wheelspin...

As for lunch, I recommend a light proscuitto, pecorino and rocket salad drizzled with truffle-infused extra-virgin olive oil with a nice glass of 1981 Penfolds Members Vintage Reserve Pinot Noir to cleanse the palatte.

95GTST,

The conditions (track surface/temp etc...) on the day/night will dictate what launch rpm works best. Your clutch will also be a big factor in how best to get your car off the line. Merli's suggested rpm & technique is a good way to go. Very harsh on a stock clutch though.

As for predicting how you go? I'd be happy with mid to low 13's (~105-107mph) with your current mods.

No no no Andrew you've got it all wrong. He actually wants to know how fast to eat his lunch (rpm lunch) kind of like a bites-per-minute sort of thing ;)

As for predicting how you go? I'd be happy with mid to low 13's (~105-107mph) with your current mods.
If he is using the standard turbo and with semi-slick tyres i'd be aiming for a 13.0-13.4sec pass (thats if the standard turbo doesn't blow up on 15psi).

:Bang:

Dont be scared to practice launches before you go out. A very quiet country road is good for 0-100 practice. The track will be different but if you have never done it before its good to get a feel on what rpm spins or bogs down. My car felt good on the street tarmak but at the drags i was getting massive tramp problems through worn lower control arm bushes and stuffed viscous lsd. When staged i hold the handbrake on dial revs and take up the clutch pedal slack, then engage it on the second last amber light releasing the handbrake at the same time(jap style).Hope you understand lol..

On regular sh1tty street tyres i launch off of the handbrake as described immediately above. On semi's, i've recently discovered that i get better 60' times (consistently 1/10th sec better), by doing a great big smokeshow first - then launching with a small amount of clutch-slip to control the wheel-spin through first gear.

Merli, who can afford the bling req'd to guzzle 1981 Penfolds Members Vintage Reserve Pinot Noir every day?!?!?

Oh and if you have a std computer, good luck laucnhing from 8000rpm. ;-)

hahaha i might be able to 8000rpm, but fat chance ill do that.

i leaunch mine at about 3500, but i hold it at 2500 at the staging lights till it starts to drop then as soon as it gets to the 3rd light down i give it half throttle and start slipping the clutch out pretty fast while moving my right foot fully to the floor, which pretty much makes it 3500 at time of clutch biting.

this allowed me to do a 13.550.

stock turbo, stock cooler, cat back exhaust, 11.3psi, 255 wide tyres.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
