Launching Techniques

[hotsaucewizard]

Thanks for all the responses guys, especially @zrk. We have a local event coming up and being a police officer has kept me from any shenanigans on the road so I haven’t had an opportunity up to this point to launch.

Surely you'd have more authority than anyone else for shenanigans lol

also any posts I make on this forum are purely a work of fiction.. I don't even own a supra. ?

I have been going to the track a good portion lately trying out different launches, running e30, DP, and 285 R888R. Wish I would have picked up 305's and probably would have gone with Nitto 555r2's instead. Locally we have only 1/8th and the quickest so far is 7.1 with a 1.71 60 ft. I have had success with 1st gear launch then shifting over to auto and 2nd gear brake boost, I use traction fully off and 18psi in the rear.

1.74 60 and 11.98 stock for me. Short burn out more just to clean and get the water off. Tire pressure about 25lbs. Full auto, sport plus mode for trans and engine, all nannies off. Simply brake torque to about 2200 and go full send on the last yellow. Easiest launching car I've ever had although all of the previous were manual trans.

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.

doing a couple of straight line races tomorrow. Is this still the general recommended launch technique? I’m on bm3 ots stage 2 93 oct tune. Never launched an automatic car, always drove manual before the soupy lol

Any recommendations on tire psi? Running 305/30 Michelin ps4s in the rear

I was able to finally get my first few wins at a 300’ drag event last night following these steps

slightly modified tho (because I’m new at racing). Kept it in auto, but I have a tcu tune so I always start at 2nd gear. I also rolled onto the gas vs mashing as I would just spin.

Thankyou for taking the time to write this, I really do appreciate it.
I have realised I made a mistake make up stages, I don't like being embarrassed so won't do that again.
I've spent more time thinking why my time is so slow and have figured it out.
I have Adhd (inatentive type) so sometimes I forget things, other times it can take me ages to start and or complete tasks. Like I said the mods list is my build and litchfield are the tuners.
I did the hybrid turbo and DO88 Intake Manifold at the same time, listchfield sent me a base map to get me rolling and then I had to send him some log files, the car at that point felt like a rocket but the EML light was on so he made some quick adjustments to keep me on the road as it was the same week he was working on that GTR that did over 200mph the other week so I don't have the full benefits of the fully tuned map yet. The data logs I sent in last time were not good enough so will have to do them again tomorrow.
The next run what you brung at santa pod is on the 28th of September. Is anyone else on here going? Would love to meet you guys.
