A misfire at 4000 RPM could be caused by several factors, including ignition system issues such as faulty spark plugs, ignition coils, or wiring. Fuel delivery problems, such as a clogged fuel filter or failing fuel pump, could also lead to insufficient fuel reaching the engine. Additionally, issues with the air intake system, such as a malfunctioning mass airflow sensor or a vacuum leak, can disrupt the air-fuel mixture, resulting in a misfire. Lastly, engine mechanical problems, like low compression or valve issues, might contribute to the misfire at higher RPMs.
It could cause a low rpm misfire/stumble/die off.
Dont drive at 4000 rpm My truck, at highway speeds, only reaches to 3000 rpm...IF I take it out of overdrive, otherwise it runs around 1700 rpm. 4000 rpm is the MAXIMUM for race shifting (give or take).
if the car is in park the almost any car wont go over 4000 rpm usaully like 3700 it is a safety issue
800 rpm
You May Have a misfire if Check Engine Light is on Have it Scanned or possibly a dirty Mass Air Sensor
The engine will have low compression and misfire, especially at idle. The misfire will seem to disappear at higher RPM.
I would only do so if the manufacturer of the equipment said it was safe. The drastic speed change could at least cause excess wear, and at worst cause catastrophic failure due to increased centrifugal forces. Logically, if the machine could get better production at a higher speed, they would have made it go that speed in the first place, right?
GXE: Horsepower 160 HP @ 5600 RPM Torque (lb-ft) 182 LB @ 4000 RPM SE: Horsepower 190 @ 5600 RPM Torque (lb-ft) 205 @ 4000 RPM
There was 2 different 454 in 1974 , One had advertised 230 HP@4000 RPM And the other had 250 HP@4000 rpm
I think its telling you to "SHIFT ALREADY"!!!. 2500 to 3000 is plenty, 4000 is abuse

It was rated at 180 HP at 4000 or 4500 RPM and 210 at 5200 RPM.
