Trying to launch auto 2g, wont go past 2200rpm

[onefast2gdsm]

Ive been trying to practice launching my car so when i go to the track i can launch it. I have a hx35w on my car, stock converter stock trans. Whenever i powerbrake it, it gets up to about 2200-2300 rpm and thats it. Doesnt pull through the brakes either. Ive heard of people atleast getting to 3000rpm powerbraking and my car just isnt doing it. Ive also been told i can activate anti lag in link while power braking to spool the turbo quicker. Obviously at 2200rpm antilag is useless. Any help approciated.

You need to tune the car for stalling. Retard timing and add fuel will help

You aren't going to get much if any boost with that turbo without some help. Vaccum pump, nitrous, take your pick. It took me about 6 seconds to build full boost on a b16g.
With no boost leaks and only running 15psi.

Also make sure you don't have any boost leaks. And remember to not try and power brake for a long period of time or you will cook up your trans fluid real quick.

Im not new to dsmlink by any means, but i am new to automatics. How do i tune it for stalling.

Do a log while stalling, then review and retard timing and add fuel for that specific load/rpm range.

 

[sk8boardluis97tsi]

well what dsmlink do you have? my dsmlinkv3 lite allowed me just to change the rpm for the anti lag

I am gathering parts for my first build, a 95 TSI AWD auto and I read like forums almost everyday. If you haven't already, check out the forums on AutoDSM and IPT (Import Performance Transmissions). I have only had SB Chevy's in the past and this is my first 4 cylinder turbo. It seems like a re-stalled converter is probably the best thing for auto/turbo cars, especially with the bigger turbo you have. I am doing the full IPT rebuild kit, and shift kit. Still trying to figure out which route to go with the converter. If anyone reads this and has a suggestion let me know. I am doing a E316g build, all the bolt-ons on the stock block and head. Thanks.

I just told you what you need to do. Stall the car. track data log. slam the bi*** rich, slam the timing back and watch it stall. I stall a stock converter, no nitrous, 3700 in 5 secs(35psi) with my compound setup.

 

[Cdc1221]

I would say the stock stall would be fine on an e316g, considering those things build full boost by 3k anyway. My 1g wouldnt leave the stall until like 2500 on the stock turbo and real $hitty brakes

 

[njclimber36]

Thanks. I figured a restall would help. I dont have money to burn but I have some and it seems to make a huge difference, Im going to run the stock 7 bolt. If it goes south Ill most likely build a 4g64. I have to swap out trannies anyway so the converter would be next to no extra work, I probably don't NEED it, but does anyone think its a worth while move?

I would think retarding the timing and making it rich would hurt stall speed if anything. But I'm willing to try it out. What's the science behind it stalling easier with more fuel/less timing? Not arguing, genuinely just curious. I always thought more timing and lean was better, now you've got me rethinking it. I know a few people who've wired the 2-step to work off the brake pedal, and you're not the first that I've heard say make it rich and take away the timing.


I noticed pretty great results with lean/good bit of timing but then again the Cyclone helped a ton. Anything that'll speed this process up I'm for sure interested in.

 

[Cdc1221]

im going to make an educated guess and say rich /less timing makes more exhaust pressure while keeping power output down to keep from breaking loose on the stall, thus allowing you to build more boost on the stall

That's about the same as what I was thinking. Just wanted further confirmation. I like knowing how things work, I can't just "set it and forget it". Mind of a Chef I guess.

What does anti-lag do?

 

[Diamond Star Werks]

Less timing and more fuel.is anti lag. anti-lag retards timing really late and dumps raw fuel. With all the extra fuel exploding so late the explosion is pushed out the exhaust and is actually going through the turbine. Essentially its combustion outside the chamber. Reason it'll shoot flames out of the exhaust.

Thats why it spools a turbo so fast and to soo much boost. Because its exploding as its going out the exhaust ports and through the turbine housing

I've always heard and ran high timing. I cant say that i've heard anyone run low timing to get up on the stall. High timing, more torque to get on the converter with, right? Im pretty sure low timing would hinder performance. From my personal experience it did. When i buried the timing on my stock-ish set up i couldn't spool a 14b. I've had some big time auto guys advise me to run high timing and lean afr's as well.

Anti lag doesnt work on auto's either. Load and a stall will out spool a manual and anti lag any day.

I dont think you can compare a compound set up to a hx running solo.

I doubt a stall would beat anti lag though. Stalling makes more engine load yes but you can get 20psi from a 16g off of just 2step. anti lag spools much faster than 2 step but it can be pretty harmful for a turbo as well.
I'm not too experienced in the auto class, however anti-lag does work very well.

I am not sure if you think my question was serious or not but thank you for explaining how to make a car stall faster for me.

I would have quoted you if I did, I was just explaining for everyone Else since they didn't seem to know anything about it.

 

[viperlp01]

Haha I am just messing with ya. I am just surprised they won't listen.

 

[burkgonzo]

Viper can you post a log? I'm interested in the setup.

 

[Cdc1221]

I am. Im trying to learn whatever i can. Just now ordered an evo x turbo. As soon as it gets here and i get all my gauges put it and get my idle issue worked out, i plan to make some practice passes at our local 1/8th

 

[Diamond Star Werks]

Well all you can do is tell them, learning is up to them. Can't learn the unwilling.

 

[donniekak]

Wow, a guy that runs 9's on an auto is full of crap about how to stall an auto.

Care to enlighten us? Rather than call the guy out and leave it at that...
