Explanation of "top end and "low end"

[Wifesblaster]

Might sound like a dumb question, but I'm sure it confuses some people. Does top end refer to the higher gears or the higher rpm range in a single gear? Say top end pipe for example. Does this mean that a top end pipe will increase over rev in all gears or pull harder in the higher gears?

I believe it means the higher rev in each gear... Helps with powerband i think I:I

That's what I think too, but as I read some posts it has me thinking.

Yeh, i think people just say "higher" thinking there own thing... No one really has the same meaning lol

 

[89blaster89]

i think it means both. higher gears and higher rev

 

[mud runner]

i thought topend pipes ment more power in higher rpms and lowend ment pore power in lower rpms

 

[Awk08]

i thought topend pipes ment more power in higher rpms and lowend meant more power in lower rpms

ding ding ding !
you can be in the topend of the rpm range in any gear

ya i win but what prize do i get????????

That's what I thought. I have been doing some reading about it and it seems some people equate a top end pipe to top speed. That's why you have low end, mid range, and top end.

I top end pipe is designed to produce the most power from the engine in the mid to top RPM range. A pipes power range is based on the design of the chamber. There's an RPM range where the pipe works like a supercharger and helps pull the air/fuel into the cylinder. That's where the term low-mid-top pipe comes from.

Gears are simply torque converters. Your engine always exerts the same amount of power and torque, although these change as the revs change. Gears simply change the gearing and allows the torque to be expressed differently.

In other words. Gears have nothing to do with top end/bottom end.

Electric engines do not need gears because they can produce 100% of their torque almost instantly and continually. Petrol engines only produce 100% of their torque at +-3000 - 4000 rpm, the rest of the time it is either increasing or decreasing, so you need gears to make use of that to get the best out of the motor.

Thats why we all know, wrong gear + wrong time = trouble.

Answer? go electric! (if it were not for batteries)

The answer is simply rev range.

Low rev, bottom end and vice versa.
