Description
Topspeed Ukraine TH400 external dump valve kit is used to control converter exhaust pressure to loosen the converter when needed. This external dump for the TH400 also includes manual and parts to modify the transmission lines in order to make the dump effective. Our internal dump valve will typically raise stall speed by 500-800 RPM. Our dump valve can be controlled via the Trans brake button or via the Aftermarket ECU and can be PWM controlled so you can control how many % of dump to use at any given time. The external dump valve can be used on the launch to help the turbo spool faster and get on the chip faster, or it can be used after the launch to make the first meters after the launch softer and more controllable with more converter slip! We can supply the valve with a hardware right for your transmission and setup.
