can I redline?
I've got a '00 3.8L v6 manual with a problem with a slight crack in the manifold and a problem with the crankshaft (not clear on what the crankshaft problem is but every time i switch gears, i hear a metal noise). also when i floor it anywhere on 3000 RPMs or after the gear shifter rattles like crazy. my question is, am i still able to shift after the start of the redline zone (my redline starts at 5300 RPMs)? would i get any horsepower if i were to shift after redline? or should i just shift right on redline? what's the bad part about shifting in redline zone, will the engine just shut off or something? i really want to know because it doesn't seem like i'm getting the engine's full horsepower and torque even when i'm shifting at around 5300 RPMs, being complete stock (but i'm putting in an air intake real soon, in about a week or so). and how do i get more hp easily without spending much money? thanks in advance
