Koolverter parts
The Koolverter keeps you in the race!

If you have trouble keeping transmission and torque converter temperatures down during round robin drag racing runs, the Koolverter is the answer.  This compact unit mounts in the space between the rear motor plate and the transmission directing cool air to the torque converter and transmission pump.  For more consistent ETs and pump pressure, use the Koolverter. Especially useful with higher-heat spragless converters.

Then you need one of these!

The Koolverter PG1 will cool your torque converter and transmission between rounds.

The 7" high quality 4 amp curved blade fan directs cooling air directly to the torque converter and transmission front pump. Why use a leaf blower? Eliminate towing, drive it back!

Use Koolverter in the pits or in the staging lanes with the motor shutdown to get rid of latent heat buildup. Cools the transmission 15 to 20 degrees in 5 minutes.
