So ive read "Ridenour's" explanation of the best time to shift (below). I understand that, but what about the peak horsepower? For example the stock 2008 mitsubishi evoultion has 290Horsepower@6500 (290Horsepower@6500RPM)RPM but has 300lb. of torque@4000RPM

I'm just confused because those RPM are total difrent, so according to "Ridenour" I'd want to shift at 6500 RPM and keep my RPM around that number. Is that correct? If so, what do i use the horsepower rating for?

And quickly, do any californians recommend a place to dyno?



That could be the way your torque curve works. All cars have different torque curves. If you don't know how the torque curve / "power band" works, let me explain. Your engine makes more power at different RPMS. That's why, it may be slow off the line, but really push you back into your seat once you hit higher RPMS. And then it may boggggg down after you get to a certain point. All engines have different torque curves, and all have ideal areas for keeping the RPM's - The power band. It's the range of RPM's where the most torque is produced. So the idea is to try to keep the RPM's in the power band as much as possible. For example, in my Grand Am, the "power band" is between 4500 to about 5500 RPMs, and the "torque peak" is 4800 RPM. So when I shift, I try to rev-match in order to keep it in that range. My car doesn't redline until 5800 RPM, but anything past 5500 in my car is lost power, I can feel it, adter 5500 it's just like bwahhhgg..........

So your CRX's torque curve could work in a way that a good chunk of the power band is past your redline. In higher spinning engines, it's often common to have the torque curve be at much higher RPM's then higher displacement engines.

Your best bet is to do some research online, and find out exactly where your engine's power band / torque peak is at. The idea is to shift out at the top of the power band, rev match, and try to land the RPM's back in the power band as much as possible.

But it deffinately sounds like your torque curve goes past your redline. Redline's are often under-estimated by the way.

So if shifting past redline helps get more power out of your power band, I'd say go for it. I just wouldn't do it on a regular basis, due to the fact that it's probably pretty rough on that engine. I mean just save it for when your racing.
