torque convertor question
medic and deezo, you guys got ur best 60' times by launching at about 2k rpms correct? now, my question is, if i had a torque convertor, and i launched at a higher rpm, with a lower tire pressure (say about 18-20psi in the fronts), am i going to see an increase or decrease in 60' times? the reason i ask is because, in this case, the chances of wheel spin are a lot higher. so is the torque convertor really worth it?

You are going to be traction limited in you launches if you launch much higher than that. Unless you have a SC, I wouldn't bother with a higher speed TC, because in everyday use, the car will feel a bit sluggish unless you lay on the accelerator all the time.

If you get a high quality higher stall converter, the sluggishness Medic is talking about really won't be felt unless you go with a much higher stall than stock. If you increased the stall by 500-700rpms and had a quality converter, you should be good to go.
Will your 60' improve? Hell ya they will....if you've got the traction. A torque converter multiplys engine torque, therefore giving you a stronger launch. Since your launch rpms will be increased, you will be leaving the line deeper into the torque curve. The ideal stall speed for the 4th gen Maxima would be around 3600rpms or so. The goal is to get a stall about 500rpms under torque peak. Unfortunately, a 3400 stall would be a bit too much for the street. You could probably drive with a 3100rpm stall. What's the stock stall on a 4th gen? 2500-2600rpms?
