The intercooler core is massive. The end tanks are nicely shaped to get as-even flow distribution as possible.
This image is from a FLIR thermal imager. In the upper opening with all the hotness is the radiator. In the lower opening is the intercooler of course. You can see how the flow distribution is pretty even from the top to the bottom of the core based on the temperature gradients observed.
If you’re looking for a quieter setup, the car can come with this 4” exhaust option. It also looks to use oval tubing in the middle for increased ground clearance and then transition to round at the muffler. Of course, the power will take a hit.
The wastegate dump is out the right front fender. MIQ faithful know the science behind external dump making more power.
To help put all the power down to the ground, Enkei RPF1 18” x 10.5” wheels with 295/30 Advans are used. Killer B auto-x’d this car a fair bit. So they used RCE T2 coilovers along with Whiteline front and rear adjustable sway bars mated with Kartboy end-links. Also, just about every bushing has been replaced with stiffer durometer bushings.
