NOSE STACK SEAL AND SHROUD KIT
The cooling system begins with vehicle aerodynamics. Sandwiched together, the transmission cooler, intercooler and radiator create a formidable obstacle to airflow. Cooling air must be under sufficient static pressure in order to be pushed/pulled through these various heat exchangers in the nose stack. Also, once through the stack, the, now-heated air, must not be permitted to circulate back to the front.
There is too much “stacked” resistance preventing adequate flow of cooling air, on a nose that is too aerodynamic: too much air going around the front end, not enough forced through it. At 60 mph vehicle speed, the stack air velocity is less than 11 mph. We have developed vehicle specific kits that shroud for additional air movement, and seal to prevent the performance damaging recirculation of heated air that occurs when the fan engages. As a result, there is a large increase in mass air flow, and reduction in ambient temperature rise through the stack. By helping to keep the thermo-viscous fan off, more HP is available to the wheels. The Nose Stack Shroud Kit contains:
- -Three piece industrial quality shrouding kit- cut for each specific make/model year, made from ¼” industrial nylon reinforced rubber.
- -Sized Closed-Cell Foam Neoprene sponge and 500 F Silicone (in the hotter sections)
- -Reduction in high speed fan activity (and most stop light fan activity) when unloaded-up to 100 F OAT. Reduced fan operation at other times.
- -Improved air conditioner performance.
- -Increased Intercooler effectiveness.
- -Lower summer towing EGT’s, 50 degrees on average.
- -Lowered transmission temperatures, 5-10 degrees on average.
- -Higher heat rejection capacity at idle or low speed operation.
- -Cooler Engine Compartment.
- -Added radiator cooling capacity.
- -Transmission cooler shroud option available (OEM cooler).
- -Installs in 30-45 minutes, complete instructions with installation photos
