I would like to be able to run E40 on Map7 for future track days, so I need a larger intercooler. On the street the OE one is fine for a few pulls but will heat soak shorty after.

I'm leaning towards the VRSF intercooler because of it's price. Anyone with any firsthand experience?

Have you considered leaving your JB4 in a more conservative/stock mode for the track?

Running a car at 7/10ths+ for multiple 20-30 minute sessions is a different animal than most FBO users who are just doing a quick 20 second straight line pull at most.

Your use case is going to be exceeding the engineering envelope of the car with far higher frequency than most other owners.
