Recently, I've noticed that the engine sounds weird at 2-3.3k rpm at WOT.
Background:
I always try to reach 5th ASAP. I usually shift at or around 3k when possible, meaning the next gear will be at 2kish.
When I'm entering the freeway, the ramp is long enough that I'll be on 4th or 5th and I need to speed up. The engine sounds like our AC fan on high until 3.3k, then it smoothens out and sounds 'normal.'
Also only noticed this on 4th and 5th.
Just making sure everyone else has the same.
