Our cars, with even mild modification, create some serious heat. As the turbo compresses your intake air, it heats up and its not unusual to see air temperatures of over 400¨_F entering your intercooler. For that reason, youve probably upgraded to a larger, more capable top mount. That intercooler uses ambient air flowing over your hood and through your scoop to cool the hot compressed air and if youre not using a proper splitter, youre not getting the most out of your TMIC. The GrimmSpeed line of splitters increases the size of the opening to perfectly fit your GrimmSpeed TMIC, which can increase your internal core volume by as much as 200%. Youre going to need every bit of that additional ambient air to keep things cool.
Each of these splitters has been designed to make the best possible use of the air entering your scoop. Weve opened up the bottom of the splitter to better fit your GrimmSpeed TMIC and weve redesigned the vanes that direct air from your scoop down to your intercooler. In addition, weve added features for up to three intercooler water sprayers to each splitter. Each splitter was designed in CAD and tested via flow simulation prior to production. Our engineers used 3D scanned CAD data from each vehicle along with the CAD data from our TMIC development to design a splitter that fits well and evenly distributes air across the entire core.
Youll also find that the GrimmSpeed splitters are very lightweight. Weve tested some of ‹“the other guys splitters and have found that theyve chosen stainless steel instead of aluminum. The reason for this is likely as a band-aid, to ensure stiffness so that the splitter holds its shape. Instead of selecting a stiffer material, weve stiffened the design, which has allowed us to use 20 gauge 5052 aluminum and drop the weight of these splitters by 300% over the competition. Instead of welding the assemblies, weve opted to use rivets. These offer the same mechanical joint but without stressing the material and because of that, you dont have to worry about breaking welds or your splitter cracking. With each splitter, well be including a length of a EPDM rubber bulb gasket, which installs with ease and will hold up very well to the harsh under-hood environment.
