Ok so i got a r32 gts-t, with mods listed in my signature thingo, and was wondering a few things

it hits peak kilowatts at 5800rpm, then drops about 3 kilowatts to about 6300rpm, So in 1st, 2nd 3rd, i should be shifting at 5800rpm?

Other question is about taking off. Do i slip the clutch from like 5krpm to get moving, or drop the clutch high enough so that it spins once or twice (about 3.5krpm), or do i drop it lower so that it doesnt spin at all, or do i drop it high so that it spins for a bit then takes off, which? It starts coming onto boost at about 3krpm hits peak at about 4.2

Taking it to calder this weekend, also wondering what sort of time should i be expecting? I wanted a mid 13 pass, but the bloke who tuned it said more like 13.8-9. Its got SPMAXX dunlops on the back (45 series) on some 17X7 rims with plenty of tread. Im not sure about the suspension but it seems pretty hard unfortunately (i assume its that which gives me copious spinage into 2nd) Er also is it worthwile dropping my tyre pressure to like 28psi? its about 38 now.

You'll be aiming at a High 13 with 170@wheels.

Drop it in from3.5k and dont slam your gear changes cause at Calder you'll get a shit load of whellspin. Just change slightly quicker than you normally would and ease the power on for he first coulpe gears. it makes a big difference, it cut my time by 0.35 of a sec

Put some MT street radials on it.

ahh ok cheers, any one else can answer a few questions it'd be much appreciated (think i asked to many :)) in particular the first one about shift points

yeh ok, i know that good suspension and tyres as well as wheel size will make my 1/4's faster but, im not really interested in any of that. Only want to know how to drive really, not what to drive as i want my car to be capable on the street of what its capable of on the strip

any one else? (in particular the first one about shift points)

You're mising the point here. Drag racing is done on a drag strip, which has nothing in common with the street. The available traction on a prepared drag strip will never be approached on a street. Nor do streets have staging lights or timing equipment.

Therefore the techniques used to launch hard at the drag strip bear nothing in common to "launching" hard on the street. The RPMs you can use are different. The rubber you can use is different. The clutch techniques are different.

With street radials on a pure street car at a drag strip, then you would launch with a high RPM as you can possibly get away with, provided you get no more than 10% wheelspin. You want to aim to avoid bogging down (not enough RPMs) and avoid smoking the tyres (too much RPMs). The sweet spot is in the middle there with some wheelspin, but it's not as easy as it looks. That's what drag racing is all about - the launch.

I'd recommend you use your clutch to modulate the power transferred to the rear wheels, even if that means not fully letting the clutch out before you reach second gear. Same goes for each gear change.

This will shorten the life of your clutch.

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
