i have a automatic transmission and i wanted to know how to imporve my time with out buying anything else big? any suggestions

 

its really really hard to tell you when we know absolutely nothing about your car. But general stuff would be weight reduction, sticky tires, learn how to launch better.........but I cant get into specific stuff with out knowing what you have and what mods.

 

ok dont laugh though! i have a v6 3.4 liter with headers, exhaust, msd igniton, and a shift kit. I dont know wut other part i should buy i am thinking about a 1800 stall. But i just got my check for $567 wut can i get with that to help improve my cars racing time? Well over the winter when i dont drive we r takin out the engine and boring it out and hookin up the engine. but wut for now with this check would help besides NOS?

 

That kind of money can get you a better ECU or some nice air intake parts, like a CAI or a bigger MAF.

 

Both of you guys with auto's a small stall will help out your times. That 1800 rpm would do much though. I would look at a 25-2800 and a pair of sticker tires, your going to need them. A shift kit is cheap and effiective. A PCM tune is good for 10hp. Some suspension lca's, subframe connectors, torque arm.

 

What is a 'stall?'

 

Remove anything that adds weight that is not needed and is not nailed down.... Spare tire, jack, back seat, front sway bar..... For example.

Stage absolutely as shallow as possible. Just bump the stage bulb enough barely light it.

Put about 43 pounds of air in your front tires to minimize your rolling resistance.

Obviolusly anything that helps it breath better like a high performance air filter, or better flowing exhaust will help both your quarter mile times and your gas mileage.

A torque converter is what people are referring to as a "stall". Basically the torque converter acts like a clutch and the higher the stall the higher the lockup. A higher stall speed will allow your engine to be higher in the power band before it locks up which can make your car quicker at the track. If you do this you also want to add a transmission cooler and higher stalls produce more heat than lower stalls during everyday driving.

 

Thanks for the explanation... but I'm having a hard time grasping the thought.

Are you saying the TC will 'clutch' until the engine reaches a higher rpm and then lock up so all the power is at the wheels, thus keeping the engine in the better range of the powerband?

Besides the heat issue, how else would this affect normal everyday driving?

 

In everyday driving a mild torque converter upgrade is not a problem. I have a 3600 stall converter set up "loose" and the car just doesn't move until I put my foot in it a bit. If you went with a milder 2600 stall speed for example you wouldn't notice much difference in normal driving but it would certainly help your track times.

I'm not overly technical in terms of the details of operation, but my understanding is the torque converter basically is the "clutch" of an automatic transmission. I have a switch in my car so when I am driving on the highway I can lock the converter so it won't slip and build up heat.

Where yours is a regular automatic transmission that shifts by itself, the addition of a good transmission cooler should be just fine for you.
