The 4L80E weighs 178 lbs in typical configuration. Unless you are racing for a record attempt where hundredths of a second are crucial, reliability is usually a more important factor. 05 second in Elapsed Time in the ¼ mile, you gain reliability. So for a small loss of power often equating to less than. The thing to remember is, typically the lighter duty transmissions become a maintenance item at these power levels. As you get into the low 10 second ¼ mile times, you may start to see some differences between a lightweight transmission and a heavier one. They simply aren’t accelerating fast enough that the rotating mass really comes into play. Our testing has shown that you will not see any significant power loss in a 11, 12 or 13 second combination. Power loss through the transmission will increase the faster you accelerate it. So what this means to the average enthusiast is the faster your car, the more power the transmission will consume. It DOES take more power to accelerate or decelerate the heavier mass. So unless there is more friction involved, a heavier rotating mass doesn’t take any more HP to maintain the same speed as a much lighter mass. Remember an object in motion tends to stay in motion unless acted upon by another force. However what is widely misunderstood is that yes it’s heavier, but that alone doesn’t cause more power loss.

The biggest loss would seem to come from the heavier rotating mass. It has a positive displacement pump as opposed to a variable displacement, it is heavier, has more rotating mass, more clutch drag, and on the surface would seem to “eat” HP. The 4L80E will theoretically consume more HP than a 4L60E or other lighter duty transmission. It’s not for everyone, but it is the unit of choice if you plan to make serious power. Simply put, from a design and engineering perspective, it’s a superior transmission in more powerful combinations. It has better power flow for big power applications, much more clutch capacity and apply area than the 4L60E. It is very rugged, has much more potential for power capacity than any other overdrive transmission on the market. Quality Control second to none, holding most parts to within.The 4L80E is a descendent of the proven TH400 transmission design. Ultra sonic leak testing for even the smallest leaks We use ONLY the highest quality friction material with the greatest efficiency of friction Over 1500 units per day hand built-one at a time If you need a special 'one of a kind' or a prototype, we can design and build it in 2 days.īelow is an example of just SOME of the things that make our process different from other torque converter manufacturers:Ĭomputer controlled manufacturing process, computer controlled welding, lock-up testing, computer controlled CNC LathesĬonverter balancing to within 1 gram of all parts internal/external We also understand that bigger is not always the best, but in this case, it really does matter.

Then go to the transmission forums and hear from the guys who install transmissions on a daily basis who expect quality. It is easy to build a website, and it can make anyone look good. Remember, there are a lot of businesse's out there claiming to be the best, and they do not truly understand what quality really is, nor do they have the required equipment. These torque converters are all built with parts that are of equal quality or HIGHER QUALITY than OEM (Original Equipment Manufacturer) parts.Ĭircle Track, Drag racing torque converter, you have found the most trusted manufacturer in the industry with Precision.
