Why does high RPM matter?

Well, let's not drink ALL the Kool-aid now. To keep it in the same ball-park I am referring below to the C5 Z06. The C6Z is just WAY over the top.

An LS6 motor does not weigh much more than an F20C. The 'vette uses some pretty high tech suspension pieces and all of it is made from forged aluminum. The GM engineers also placed the transmission in the back of the car to help balance out the weight distribution of the car.

So between the lower CG, wider stance, and wider tires the Z06 has a far higher lateral G than the S2000. Throw in the extra HP with the marginally heavier weight and the Z06 is an extremely fast car.

At the end of the day, I don't care how many valves the car has. I want a car that I find "cool" and there are several things that make a car "cool" to me. One of them is uniqueness. I want something special, unique, something that is not easily replicated. Fast is ALWAYS cool, but if it's not unique, it better be DAMN fast. (So an SRT-4 just ain't gonna git-r-done.)

I am not convinced that the F20C is "more refined" than a SBC. Sure it has pushrods and only a single cam, but it makes more power and gets better gas mileage.

If the smallblock Chevy,(350 c.i. or 5.7 liters)was making 120 bhp/liter,as the F20,it would be up to 684 bhp.
Also,tell me why,they rev the F-1 at 19,000 R.P.M.,and tell me what kind of H.P.vs Torque they have;and they're quite fast.

Lets say your opponent has a redline of 7k and you have a redline of 9k. When your on the track and your about to hit a corner it would be useless to upshift just for that fraction of a second just to downshift to take the turn again and with 2k more you would have an advantage over the guy with 7k

I couldn't find any specific HP ratings for F1 Cars. However, keep in mind they have specific requirements on displacement.

If you want to go for small displacement, then you either have to rev the crap out of the motor or go to forced induction for power. If people thought comparing an S2000 to a Z06 was stupid, comparing a street car to a race car is really, REALLY dumb.

Yes, if the SBC made 120HP/L it would have more power than an Enzo. So what? It already has more power than the S2000, weights only slightly more, and is as fuel efficient WITH the greater displacement.

There are too many variables to simplify this. The gearing of each car and the power it delievers in the lower or higher gear would have such a dramatic impact on corner speed. Not to mention lateral grip. I see what you are getting at, but the comparison is hard to do.

The closest possible comparison is an '03 to an '04 S2000. There was a lot of testing done when the '04 came out and the testers found that there were some places on some tracks where holding the gear in the '03 helped, and some places where the added low-end torque helped the '04 to the point that it was almost a wash.

Not to be confused with an ap1 vs. ap2 thing....

But...

When you hear the engine revving through its last few hundred RPM on its way to 9 grand, its a thrilling sensation because you feel as though you are literaly on the edge of total distruction; that if this thing goes now, its going to go big......... then you shift and do it again !

I feel dumber for reading this
If you have listened to what other people have said with the same logic, it makes sense. A guy up there replied with an equation..

Remember, horsepower equals torque multiplied by RPM divided by 5252.
This was exactly the info I did not have. - Thanks Jakup

This is exactly what I am battling, and as Ruexp already summed up, there are too many variables to make this a true statement. That guy with the 7k RPM redline may have a higher speed per gear... cornering speed could be the same regardless of redline. It is the way the engine makes the most power in the best way possible that really matters.

Like I said TWICE, 9000rpm rules! I just question the way people boast it sometimes.

This thread sucks. The 9000 rpm is just thrilling, fun, and unique.
