Can't redline in 4th and stop gaining speed at 129!!!! HELP!!!!
Tonight when my friend and I were on the way to town we decided we wanted to see how fast my car would go because I hadnt topped it out yet and we both wanted to see what it would do. It was really nice all the way up through the most part of 4th gear and I just stopped gaining speed. I was at ~128 or 129 and my RPM's were at about 7000 i think..... anyway, I've heard people saying that stock they go like 157.... did i mis-read something or is my car just not performing like it should? Sucks pretty bad if I have a car that i use the entire powerband up before i even get into 5th gear.... any info and help is appreciated. Thanks ahead of time.

Something is not right.

what does your power curve look like? perhaps you just dont have enuf power/low boost/popped engine or something. i would check about the fuel cut though, what boost psi are you running?

My car was doing the same thing, first few times i topped it out (2x) was a hair past 150 (redline 140 in 4th, and a little more out of her in 5th)
Now (4 months later) she wont redline in 4th like she used to (runs out of breath at 130) similar to what you described. I'm blaming it on a clogged cat ( my boost now drops to 6-7psi at redline in the 2 highest gears)
If you dont have a boost guage, I'd suggest you get one asap, if you dont have a downpipe, order both from someone and save on shipping.

Wow, when my car was bone stock I could only get up to 150, now granted once I got a boost gauge and realized I had no secondary boost I felt alot better. Just a hose popped off one of the solenoids under the UIM, then I could really get into it, that was great. So I say check your hoses, and like ijneb said it could also result from a clogged pore or main cat. Definetly get the boost gauge though!

Regardless of what gear you're in at red-line, that all the speed you're gonna get!. If you want additional acceleration/velocity, try shifting to 5th next time. BTW, do this at a race track, PLEASE!!!!
Also, hesitation may be a sign that the Plugs need to be changed.

Further to my 17-year old comment, since there's a problem with the car, that brings into question how well the car is being maintained -- going triple digits in a poorly maintained car is a dumb idea, at best.

Next time you may want to try to finish reading the entire post(s) before posting thoughts that contain insipid remarks.

Also, he didn't experience hesitation, his car just stopped accelerating at 129 mph. I doubt that plugs could kill 30 mph off the top speed, but I suppose anything's possible. The most likely culprit is a boost leak though, as that is going to kill power more than anything else.
