aftermarket torque converter advantages

[x628x]

what are the advantages of getting an aftermarket torque converter? ive done alittle research on this, but not much. i know dunrite and protorque or something make them, but which is better?
and would i still have to worry about holding the brake and gas for more than five seconds if i got one or not?

There are several advantages to having a aftermarket torque converter.

First off, a converter of high quality should offer you a great strength advantage over the stock one. Hardened spline inserts, larger bearings, furnace braised fins, and carbon fiber lock up clutches are some of the features that you should expect in a performance converter.

In addition to that, a properly designed converter will enable you to take much better advantage of your powerband. Essentially, it will allow you to rev the engine higher into the torque curve without a load. This in turn will raise the rpm at which you will eventually overpower your brakes when trying to hold the vehicle against them to build boost and get into the power curve of the engine. Of course, this will translate into a much harder launching car.

A performance converter is one of the most effective modifications that you can make to an automatic transmission equipped vehicle. Without adding a single horsepower- only utilizing your power better, you can expect quarter mile et reductions between 1/2 to a full second. For the money, that's pretty hard to beat.

Try looking at http://www.levelten.com/ they also have a performance torque converter for our cars.. They may also have some info about it that may help you decide what to do... There is also a member here on Tuners "Transdude" He also works on our Auto's and has some great posts on the subject. Im hoping to chat with him next spring when im ready to start my trans upgrades.

does this mean that you can power brake for as long as you want without worry?

also, which torque converter on your page will work with my car? is it the custom one?

whats lockup and non lockup? and which do i have?

In answer to your first question. With any automatic trans, you want to minimize the amount of time that you power brake it, tremendous heat is generated by the converter during this time. You only want to do this for as long as is necessary (a few seconds at a time).

Second, for an accurate recommendation on a converter your best bet would be to email me with the details about your application.

We have a standard high stall converter that works well with most mildly modified cars, a custom converter- which is made to the specific application (this is for more heavily modified vehicles) and we have a 9 1/2" billet unit which is for very high powered applications.

"Lock up" refers to whether or not the converter has a clutch in it that applies at highway speeds. The factory added this to improve gas mileage and reduce transmission temperatures.

Early Turbo models are non- lock up, but all other DSM converters are lock up. The easiest way to tell is to count the wires in the main trans wiring harness.
4 wires= lock up
3 wire= non- lock up
