RPM's lower for a sec at high speed?
This is just a curiosity question,I actually didn't feel any loss in power when it happened...
But I was driving fast in my stock '06 lx sedan,right as I hit 94-95 the engine rpms lower just a little,is there a reason for this?It's happened every time I go this fast..but I never feel a loss in power.
You can hear it between 1:30 and 1:40 in my video(again,right when i hit 94-95 mph):

If you think a good mechanic is expensive, try hiring a bad one

I never tried to make one go that fast at wide open throttle, and If I had to guess, it is trying to apply the TCC just before redline, and a drive with a good scanner might reveal exactly what is going on there....I notice you lifted off the gas immediately after that.

Its the rev limiter..when you hit a certain RPM it drops down 200 or so rpm and recovers..its to help provent you from blowing it...I don't have the exact numbers atm but that is what it is..

The kid said it doesn't lose power when the RPM drops the couple hundred, so I really don't think it was the rev limiter. Rev limiter shuts down injectors.
I don't think he hit the rev limiter since it still had one more gear to go.....at redline it would have shifted to the next gear, not bounce off the limiter....which it does do in the next segment at around 103mph or so.
I'm sure the car has a speed limiter built into the PCM too. If 108 is all it will do, then it's a good bet that's what the limit is.
If we had one in the shop I could check what that is real quick, but there isn't one in here at this moment.
I'm not about to go try to actually drive one that fast, that's against the law.
Kid, it's easy to count the gears.

Just checked an 06 in the air, run to an indicated 136mph with no shutdown.
I'm not gonna push it, I don't want to buy any tires or knock the car off the hoist from vibrating.

Driving 100mph on a public road is dangerously close to street racing, the only difference being the lack of another car and driver.
Hopefully you've gotten the answers you need.
