How to launch on boost

[Angel]

Just keep practicing in a empty lot or street until you know how it will behave.

That way you can replicate it and maybe even take a video of the steps so you see exactly what you need to do at the track too.

Agree!

If it doesn't rain this weekend I will give it a go and have the wife record me if its successful.

Maybe try starting in 2nd gear like brancky suggested for RWD Stingers.

I did this again yesterday and LOL the lack of traction is comical, even in 2nd. This was on a concrete backroad though.
The trick is to go like <10% throttle until the car stops completely, then slowly start ramping up the throttle. Mine stops in the same distance every time but I still think it would be hard to stage at the track. In order for this to actually work (for RWD) I think we would need to devise a custom map 6 on JB4 to limit boost at certain RPMs instead of using boost by gear

 

[Angel]

If i pull the ebrake up and smash the throttle the car will pull through it. I ease into it and it seems to hold but i also only have the jb4 and cone k&n filters. If you are full bolt on you may be making more power at that rpm with boost and that could be why it is pulling.

I am not full bolt on but I do have intakes, downpipes, muffler deletes. My biggest difference maker is that at the track will be using Map 5 which is more aggressive than map 2.

I will try it in an empty road or practice it at the track. They have an empty road strip that people can practice their launch. I wonder what kind of stress does this launching/holding on your E-brake do to the rear calipers/pads.

I am still curious because if launching on boost is successful at the track. If when I am line up ,the car wont move so the staging is not off. It could potentially improve 1/4 mile times.

This will dramatically improve 1/4 mile times if you can stage. You'll be looking at a 1.7x 60ft potentially which means 0.1-0.3 seconds off the typical 1/4 mile time for these cars

Sir you are right in theory, now if I can make that happen in reality it will be an historic day!

I don't want to get myself pumped up lol.

I need to see how the car behaves, staging is going to be the challenging part.

I don't have many flat none busy areas by me. I had to go out of my way on the way home to try it yesterday. The road i normally launch on has been flooded for the last month or so. But if i go by what the jb4 says on 0-60 (i know it isn't accurate but it is a measurement) i went from an average of 4.5-4.7 using LC on a flat spot to a 4.1 with a slight uphill. I am off the last friday of may. If it doesn't rain i would like to go to the 1/4 track. Last year i went to an 1/8th track and was only doing a 2.0 60 foot and 8.2 @ 89mph using LC. IAT was way high (logging 140*) and was only putting out 14psi on map 7 with e30.

Not sure how long the car will hold on the ebrake but i would bet start it at the yellow and it should be ok if the car is holding. As for drivetrain i was thinking of using map 6 with the 4psi over stock up to 3500 then go to 7psi over on e30/race gas.

Map 7?? Holy cow and only 14 psi?

I was hesitant to use Map 5 lol

Yeah i'm not sure why, i figured IAT being so high is why. I let it cool down for an hour and it started cutting out from my plug gap too high. I have since lowered it down and put a new set of densos in. We shall see sometime soon.

Will be hitting the Richmond Drag strip 1/4 mile today, pulled the rear seats for weight reduction. Agency power intakes, and BOV, Race chip RS at map 5 of 7, Hollowed my second cat and took the mufflers off temporarily while my custom stainless is being built. Ill do an LC launch and an Ebrake launch and post my result and differences. I was able to stage with the ebrake on the 1/8 last time i went to a strip and was hitting 1.8 60ft on a GT2 AWD... i should be able to set a record tonight if i do it correct, wish me luck!

My launch control never dips above 2100-2200 and I dont ever get boost off of it either..

And thanks lol, I've been reading for a couple weeks now, and finally decided to start an account!

Go catless with full straight through exhaust and high flow intakes and it will spool with factory launch control lol.

I don't see what the big deal is with transmission loading everyone keeps bringing up. Isn't the ZF8 rated for much higher power and loading than the stinger can dish out anyways? It's the same transmission in the BMW X6M isn't it?

Have you tested how long it will hold before going? Good luck! Ready to see the results for sure.

Nice Man!!!

Try to get some videos of your runs and share the slips if possible.

Good Luck man!

LOL take that number #1 spot and make history....

I am more worried about my transfer case, front drive shaft, axles, front diff than i am the trans and rear diff. Mine is a world of difference on LC (0.5-0.9psi 2000-2200rpm) vs ebrake (10-12psi 2800rpm)

Ill have the go-pro mounted and have someone filming from the sideline.. Ill throw up the videos on my youtube: That_ Fast_Kia

Oh sh#t I think I seen a video of yours yesterday LOL!

You are trying to reach the 11 second quest.

Good Luck man!

Thats what im doing. 2 1/4" Stainless straight piped with a resonator only leading into quad akropovic titanium/carbon tips... all of it is being fabbed up by Boost Division in VA beach, VA... should turn out beautifully!

It has little to do with the power rating of the transmission, rather it is the effect on the torque converter and fluid. Holding the brakes while building boost will heat up the transmission fluid. It held for too long, it could scorch and varnish the fluid. The possibility also exists that the structure of the torque converter can be damaged with excessive abuse.

That being said, I tried the holding the e-brake in the up position at a stop light. I felt that the engagement was often abrupt but not always. Sometimes the car crept forward, other times it didn't. Finding a way to use this at a drag strip (in my car) may prove difficult. There seemed to be a delay upon releasing the brake and when the car left. HOWEVER, when all things worked as desired, my car took off! It is definitely building boost prior to launch.

It was so good, that it almost seems like an "easter egg" that the engineers left in the programming for enthusiasts. I think with a little practice, and a transmission fluid cooler (if available), this could be a very effective way of shaving "10ths" off of times. "Good find!" to those who discovered this.

I feel this is how the car should launch already haha. I have thought about trans cooler. Need a way to log temps while doing this. Definately would give it a cool down between each run.

Before you know it, oil coolers flood the market for the stinger and drag records get broken .
