Your red line is basically what you shouldn't spin your motor past; it has nothing to do with tq or hp peak.
Sounds to me like some people should hit the books!
Keep your cents, you'll need them to help with your education!

I was referring to variables in different motor types when stating the 80%...Comprehension was a bit off but, my blame for imporper punctuation.
Your redline is set by the factory as the safest RPM you can run your motor without a greater chance of Valvetrain Failure or other possible problems including issues with shortblock etc (talking stock) ona built motor you should understand the parts you use and set to there.
We should hit the books? Then do you realize that Torque is what turns all the parts that make you move? Or that HP is calculated and based off yoru torque curve considering HP=Torque x RPM/5252. I also stated in the lower gears I.e. first and second and sometimes 3rd since the ratios are numerically greater thus multiplying TORQUE. Anybody that understands how power is transfered through gears knows that Gears Multiply Torque but Divide RPM, This is why your acceleration is greater on a 3.33 gear with a 4.00 final drive than compared to a 2.25 gear on the same final drive. Changing the final drive has the same effect, but this increase in acceleration due to the multiplied torque comes at a cost of actual Speed due to the division of the RPM that the motor makes to the wheels. That is why Torque is multiplied by gear ratios and not HP. That is also why manufacturers base the gearing of thier cars off the Torque and not the HP.
Although basing your shifts off HP is true in Top gears such as 4th and 5th. Before you throw insults understand cars better.
there how about 10 cents rolled into one package.
