i would launch as per how much traction i was expecting to get, i.e tripple plate clutch on full slicks at all 4's with say 300kw pretty dam hard lol, then again im not worried to break shit as im a mechanic :D so if u had stock clutch,tyres and power. no point doin a redline dump cause you'll break shit and prob slip somewhere along the line

5,500 on yoko a032r tyres, works pretty good. little bit of clutch slip from when the red light comes on until it goes off 3-5seconds. handbrake to hold the car. drop the handbrake and clutch, floor the throttle and off you go.

But it depends what sort of surface you mean too, that is for a circuit starting grid.

You can significantly reduce shock on the drivetrain (gearbox, rear diff and driveshafts) by preloading using the handbrake.

As Duncan says, slip the clutch to the limit of what the handbrake can hold and then floor the throttle whilst releasing the handbrake. If you get the timing right, you are just finished releasing the handbrake when it's time to snatch second. I then like to get both hands on the wheel to help counter the impending torque steer.

Personally, when I launch my GTR from a measely 5000rpm on my way to a 2.1 60ft it is because:

1. I cant be stuffed fixing broken things anymore.

2. I find I am getting more and more mechanical sympathy (because of point 1.)

3. I'm not really into Drag racing and getting my time down to the last 10th of a sec dosnt really matter, people can basically work out what ET your GTR could acheive if you did a Hard launch anyway by looking at the 60ft time, ET, and MPH.

Mine runs a 12.6 @ 113mph with a 2.1 60ft.....its fairly obvious if I did a full limiter launch a 12.3 could be achieved.....So why wreck your own car trying :laugh:

My Boss's Targa car launches at 7500 rpm. Twin plate clutch, 330+ rwkw.

Has Motec, so it's s simple procedure.....

Engage clutch, select first, plant right foot, when it sounds like there is gunfire behind you, disengage clutch as quickly as you can.

1.5 seconds later flat change into 2nd (gotta love flat shift control)

1.5 seconds later flat change into 3rd.

Grin like idiot, giggle like school girl.

Stop. Repeat.

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
