i just noticed this & thought it was very funny, the 1.8 v6 mx-3's make max torque & hp at 4500 rpm, yet the redline is at 7k, & every one of these guys i watch on youtube runs their car clear to 7k regardless of the fact that they do much better at 3-4k lower rpms & its not necessary to rev that high as the power drops off when you can just shift & use it as its building to its peak & a bit past. i just think its funny that none of these guys realize that they are ricing without even realizing it (probably). thoughts, anybody got anything funny to say about ricers or a video/story/etc...?

just because u can run 7k rpms doesnt mean u shoul

I was hitting 6750 on a regular basis on my 1/4 mile runs... I did that because my gear spacing is so f'ed up if I shifted any earlier it would drop the rpm's below my power area and the car would bog.
Sometimes you run a shift high to make sure when it hits the next gear its in the sweet spot.
I'm dropping it down to 6200 max now, since I'll have a 3k converter and the nitrous so I doubt I'll have any bog spots LOL

I'll agree with that, but most 4 bangers don't make much power unless they are spinning like a top too.

Issues who has a 3500 swapped into a Corsica told me the other day he had his up to 8500-9000 once and yes the valves were floating but it survived... LOL
And throwing on a turbo on a 4 banger kind of defeats the purpose of the N/A discussion... A turbo will help any motor in the upper RPMs... And yeah there are some high power N/A 4 bangers, but they rev to like 8-9 grand... No thanks.sigpic New 2010 project (click image)

A little lesson in physics...
Torque is produced by the mechanical, axial (twisting)force converted from thermal combustion. The axial force must overcome the inertia of the standing body since inertia is the force that retains the state of motion and is impacted by velocity
Torque in an engine will continue to increase with velocity until mechanical and thermal coefficient loss is equall to the energy produced by combustion.
If an engine has been built with enhanced breathing, better thermo-efficiency and sufficient fuel delivery, then coefficient loss is minimized.
An engine's horsepower is measured by its peak "power-producing" speed (rpm) x peak torque (ft/lbs) / 550. This means that total power output in an efficiently aspirated and well fueled engine will increase with higher speeds.
Now that the lengthy explanation out of the way, what is exactly wrong with building a high revving engine?
How is this so "rice" as you put it?Took a break from working on the car. Got some better tools, got a better shop, got a better job... Its time to burn metal!
