How to not spin in first/second under WOT?

[FLtrackdays]

I don’t even try to launch my Supra. I just start out slow and then gun it in sport mode. Let the Supra and some steering & throttle modulation do its thang. It’s still hard for most cars to keep up. But… There’s no doubt I’d be dust in the wind against someone like mighty zrk that can really launch the car. Then add to the fact he somehow can make these things with a ridiculous amount of HP and not break ?

Funny fact @Evolution my S2K had a detachable steering wheel. That poor little thing. I banged her up all over FL tracks. Much more cautious in the Supra this go round. Only spinning out or running off track where I know I can ?

Never launch in first, make sure the tires are hot. Get good tires. Make sure you have the tire pressure correct.

0. Sport Mode
1. Tap Traction Control - (turn off traction)
2. Hold Traction Control - (turn off VSC)
3. Switch to manual mode
4. Burnout in First gear in the water box
5. Approach staging lights
6. Shift to 2nd
7. Attempt to push the brake pedal through the floor with your LEFT foot
7a. Pump Brake Pedal HARD
8. While holding the brake pedal down, bring RPMs up to ~2k RPMs quickly (you'll feel the car "squat"), this is the torque converter loading. Boost will climb.
9. On Green - Mash gas & release brake
10. Shift when you see the indicator reach 55-5600 RPMs (stock turbo)
10a. Don't shift out of 5th, ride it through.

Pushing much harder than 2200 RPMs loading up the converter is a sure-fire way to snap an axle after a couple of passes, and it's 3-4 months for a DSS axle. Careful.

Great info. So keep TC fully off even when ripping down track? Would it be a bad idea to put it back into sport traction to prevent it from getting loosey-goosey half way down the strip?

No don't do that.

@zrk , What is "sport traction"? I am trying to figure out if one tap TC button is fully off or just reduced TC intervention. I know that holding it turns everything off.

My car seems to hook up nicely flat out in 1st after 1 tap TC button, but chirps the tires on the 1st-2nd and 2nd-3rd shift. I feel like I would spin them up more in 1st if TC was fully off. Car has more power than stock too.

I am not launching from a dig, just WOT from 5 mph roll. The car accelerates way faster and doesn't pull power like it does with TC fully on.


EDIT: I'm reading the owners manual and it says its "Traction mode - provides maximum traction - optimised for forward momentum" - but seems to indicate it is for snow driving...?

I’ve been trying to do some decent pulls for Jesse for my custom JB4 map - now that I have a heat exchanger. Unfortunately I’m back on stock tires. This Supra pulls like a bat outta hell ? with every gear shift. I couldn’t imagine launching from zero ?. Are you taking off in 2nd gear?

Reduced intervention. It still intervenes if you hard launch it from a dig or overcook a corner, but will allow a little bit of slip.

Would you launch in 2nd gear with the manual transmission as well? All I do is spin even with 295

I'm not a drag racer, but I wouldn't, especially given the uncertainty about how robust the clutch is in the MT. 1st in the auto is shorter than 1st in the MT, which is why people launch in 2nd. Also, on the auto you are just putting the heat into the torque converter, which can take it for short periods.

I have a 2024 MT and I find it very difficult to break traction in 1st gear in a straight line.

I wish it was more tail happy.

My car must be an anomaly. I run full auto mode on 200 TW tires starting in 1st and hook very well. Actually pulled a 1.72 60 ft time on a prepped track on the way to an 11.98 quarter when the car was stock. I tried starting in second but even loading the converter to 2200 rpm the car bogged and did a 2.0 60 ft. I now run a DP and JB4 with a custom Jesse tune and still get pretty good first gear traction at the autocross. Can’t quite leave at 2000 on the unprepped parking lots but as long as I don’t go over about 1700 or 1800 tops it still squats and hooks pretty darn well.

Haven’t been back to a drag strip since the DP and JB4 though. I’m more into AX and don’t want to worry about axles. I just wanted to see if I could get a time slip that started with an 11 and since it happened, no desire to go back.

Really? I haven’t done any launches but from a ~5mph roll I break loose in 1st basically every time when I pin it (stock tires and power)

I am trying to do the same thing. My car is also stock ties and power. Do you think there might be something wrong with my car?

Are your tires hot and what kind of surfaces are you driving on?

I run Nittos and have to make sure they’re hot to grip in 1st
