Ok, my question is this: People will say like "get the CC306, its top end is amazing" or "get this cam, the bottom end is great"

Now does that refer to RPM range or velocity of the car?

Like will a better top end cam (i.e. CC306) give me tons of power when I am cruising on the freeway at 60 mph at ~2000 RPM's ? Or does that mean when I have it at WOT and I reach like ~6000 RPM's I'll have a ton of power there?


So what I want to know is, what is a good cam to have so I am able to race someone from a 60 mph roll and have my power there? Would I want a good bottom end cam or good top end?

Sorry if this is a dumb question, but I was just confused

 

Top end is higher RPM’s. If you are racing from a roll, top end is what you want.

 

well, in genral- you want top end in a race- so long as its not a short race.

The way the math/physics behind it work is you make more power by revving higher all things being equal-
but then air flow restrictions come into play because what gets more air in and out-
a valve open for a minute or one open for an hour

so it becomes a related rates equations and all kinds of good stuff i'm still readin up on.

HOWEVER- you acceleration is defined by your torque curve.
your acceleration is the derivatve of your tq at a given rpm-
so you realy want more average torque

ok i'm done for now and i just hijacked this thread and turned it into a bid debate because i left this so unfinished and wide open
