The easiest solution is to have it after, cause space and heat is a problem.
Im runing the turbo top mounted and also have T4 twinscroll housing with a quick spool valve (sequential turbine scrolls) and it just barely fits.
(Edit: I removed images, not relevant to the thread topic.)

The caps seems to be a good solution for a buffer for the battery, but it depends on the voltage reguired by the el-motor if its a 30v++ system you need a lot of caps and batteries, space and safety must be considered.
The supercapacitors seems to drop linear in voltage as amps is discharged, so this is not good for the elmotor speed controller but I guess if its parallell to car batteries the dropoff will stop, until the battery gets the load and it will probably drop a tiny bit more with high loads.
Ive seen youtube video where a guy started a car multiple times with normal size battery sized boostcap unit, no batteries and he shut the car off immediatly so it wasnt recharged much so they lasted much longer than I thought, really awesome stuff! Ive never heard about this supercapacitors before today, so it blowed my mind how the performes compared to normal capacitors.
