Car shut off. Sounds way different now
 
So I was on the highway and I floored my car in second and hit rev limiter and it shut off. Ever since that the car is very quiet compared to what I Was before and the supercharger sounds way different. Any ideas? I can’t really tell a loss in power or anything

Are you mechanically inclined? Pull the valve cover and see if you dropped a rocker. It's fairly common in these engines with rev limiter related mishaps, and will cause the car to sound choked or muffled.

When you say the blower sounds different, what do you mean exactly?

yeah I can do that I’ll check later. The blower just has a deeper whine and doesn’t sound right and there’s kind of a whistle to It almost

While you have the valve cover off, it would be a good time to check that the timing chain guides are in tact, and replace your chain tensioner if it has never been done, depending on mileage.

If you lost a rocker arm, some might say it makes the car "rumble" or sound like a subaru. Is this the case?
