Question Turbo Lag

I am having a problem with turbo lag in my wrx. I have an automatic with a VH 30 turbo. How would i go about getting rid of the turbo lag without using Nos.

You could get a stall installed on your transmission if your using it for racing.

you could either get a better tune, or get a smaller turbo. whatever the case may be, the bigger you go, you will sacrifice for some lag. you could get STi heads and run the AVCS which could get you better low-end response, but then we're talking some $$$$$$$$.

Port matching heat wrapping new ecu w/antilag and a good tune. Or get a new turbo.

Modding your torque converter to a higher stall speed will help off the line performance, and you wont feel as laggy. The fastest WRX in the world is an auto.

Do a search on torque converters. Basically they are a liquid filled device with vanes that throw liquid from the centre to the outside creating more torque. Actually, i cant exlpain it. They are complicated. Go to an auto shop and get a modded one, and bolt it straight in. You cant set it or anythin, the stall speed is dictated by the angle of the vanes, the viscosity of the liquid etc, all physical charcteristics. Or you can mod your one you have, but i wouldnt bother. To see where your stall speed is now, roll along in 1 at about 5 kmh and plant it. The needle will rise up and where it hooks up is your stall speed. It is a rough test, but you can see the area it is in.
So see the experts and get a modded one fitted.

You have no mod list, that would be of great assistance ... I'm guessing that since you're running a vf-30 that you've got an aftermarket up-pipe in there already ... (If not that'll definately help) ... Also, look up Deadbolt @ www.deadboltspeed.com ... You could always give their Monster Port and Polish a go, that would kill off a bit of spool time as well ... Good luck, and post up your mods, alot of things induce lag ... IE: Front mount intercoolers, headers, yadda, yadda, and then some reduce it ... Up-pipes, downpipes, blah, blah, blah ... You get the picture ... Pepole can help more if they know what you're running ...

You need to have your torque conveter stall speed raised. This allows you to hook up later in the rev range, thereby allowing you more of a chance to be on boost. It can really minimize the lag issues you are feeling.
