My Whipple 2.9 Gen 3 Stage 2 warranty is up in a few days. All has been great. not a spot of coolant on my shop floor. I have searched every where for a small leak, nothing. All I can see is that my coolant for my Supercharger is slowly going down. Is that unusual? 3,500 miles plus 7 hard runs at the drag strip. Or is it just time to add coolant or should I be concerned? I been watching too many Dorian videos, I get side tracked!

Typical on a fresh install if all of the air wasn't burped out. I wouldn't think it would take 3500 miles though. Maybe you're just noticing it?
When you fill it up, try topping it off with a bottle of water wetter if you have not mixed any already.

If you have never added any coolant after install, then what you describe is normal, as air will continue to be purged out as you drive around. However after 3500 miles the air should be purged, so once you top it up if it continues to go down a substantial amount I'd take a long hard look for any leaks or signs of coolant evaporation about the fittings. If you don't find any, then pull the blower and look at the intercooler core and check for leaks there.

But before you get concerned, what you are experiencing is probably normal as it sounds like it was never topped up.

I'm curious as to who you had do the install on your truck?
