Default high rpm = power loss ?

I've never really driven my car hard until yesterday. 01' 2.5 RS 5-speed. Anyways, I'm acclerating quite hard and hit 7000 rpm in 2nd gear. I noticed that the power seemed to back off. It felt like either the ECM cut fuel to the engine or the physical connection between the trans and the engire was temporarily cut. Is this something that occures normally to protect the engine from damage at high rpm? I did a search for this and didn't find anything.
Thanks in advance.

1) isnt ur redline like 6200
2) higher rpm doenst necessarily mean more power
3) that felling your getting has gotta be the rev limiter

Yeah...you could not have hit 7k rpm while accelerating. And the ECU does cut fuel and spark at 6250rpm, feels kinda like hitting a wall.

Thanks for the replys. I'm going to search on the board about the "rev limiter." I'm was not sure exactly where the RPM needle was, I thought it looked liked 7K. Man I wish my car was faster.

Even if the rev limiter did not kick in or a fuel cut, you don't want to rev that high anyways. There's no power up there in the 2.5RS. The torque falls off significantly and it's not worth going past the stock limits unless your cams or something is done to keep the torque from falling flat on its face.

Just due to momentum the tach needle may go above redline.

So, we pretty much agree that you hit the rev limiter.

LOL I never had my Tach on both my cars go over the red line.. My EJ18 is 6,000 and the EJ25 is 6500.. Both of them kick in with the rev limiter kinda abrupt..

I find that after 4000 Rpms in the EJ25 thats about all their is.. It pulls good from a Stop
