two questions about engines:

[fyneyoungstunna]

What are the pros and cons of high rev vs low rev
What are the pros and cons of I6 vs V6, and which one is a better NA build?

[PeaceOnesxWai]

uhh...

Theres so many factors to even weight in before you can talk about high rev vs low rev.

heres a brief if its on something like a honda motor
Pros : more power on small displacement engines
cons : more moving parts, more friction, more wear, more expensive

I6 vs V6
Only thing i can think of V6s are more balanced on the crank.. but ive seen I6s make crazy amounts of power.


Whats better for N/A? Thats easy... Whichever motor has the most aftermarket support


This is the best forum for N/A power (http://honda-tech.com/register.php?registration_type=-1)

for high vs low revs:
lets say its also for v6 or I6. on the I6 side i have one NA and one T its the nissan L series out of a 280zx. on the V side its the vg30de, as I am going for a lil higher compression, a more responsive powerband, and better throttle response (which I will be using lighter rotating parts and better valvetrain to aid in this)

The straight-six layout is the simplest engine layout that possesses both primary and secondary mechanical engine balance, resulting in much less vibration than engines with fewer cylinders.

Due to the odd number of cylinders in each bank, V6 designs are inherently unbalanced, regardless of their V-angle. Each cylinder bank in a V6 has an odd number of pistons, so the V6 also suffers from the same problem unless steps are taken to mitigate it. In the horizontally opposed flat-6 layout, the rocking motions of the two straight cylinder banks offset each other, while in the straight-six engine layout, the two ends of engine are mirror images of each other and compensate every rocking motion.

Low rev engines are designed for Tq(KA). High rev engines are deigned for Hp(SR).
