You are just all over the place. Just about everything you just posted is completely irrelevant and refutes nothing.

Yes it's about area under the curve...hence why what you said a few posts up is complete bullshit. You think longer gears are going to make our cars faster from a roll? A peaky car will take even MORE advantage of short gears because they DON'T have power under the curve. You're out of it. You're making it up as you go along. Stop confusing people.

 

dude.. no matter what you say.. 4.77's arent good for roll racing..

these cars are pretty close.. but the vette was coming back every time..[media]http://www.youtube.com/watch?v=PBf-hoW_rUk [/media]

another one.. now you cant tell me that the z06 (c5) has and advantage over the s2000 other than the gearing that is has.. the s2000 shifts like twice to the vette's one shift..[media]http://www.youtube.com/watch?v=F78K8mssD6Q [/media]

 

You don't even know what you're debating. I'd suggest some ADD medication. If you honestly think longer gears are an advantage for a peaky car like the S2000, that's fine. Enjoy hard parking, street racing, taking HD pictures of your car and stretching your tires.

Seriously - give me a HALFWAY technical explanation (besides, "dude no matter what you say...") as to why 4.10s are superior to 4.77s in a roll-racing scenario. Two stock cars. And I want you to think long and hard about how small the S2000's peak power window is and how shorter gears KEEP THE CAR IN ITS SMALL POWER BAND.

 

The car will be in it's power band reguardless whether it's going through it faster or not.. Honda geared the car just fine.. 4.77's are for track purposes and maybe dig racing..

Tell you what.. You go run your stock s2000 from a 45 roll against a s2000 that is stock with 4.77's.. I've beaten one before.. Granted it was an ap1 but I doubt that makes a difference..

And pm me your results..

 

I just got a detailed explanation on the subject..

And from what I was saying showed the weak points of the human body's capabilities.. You can only do things so fast.. So if it takes you ___ amount of time to shift.. Then that's ___ amount of time that you aren't accelerating.. I have to admit that I was wrong about the 4.77's.. The gear should in all honestly accelerate harder.. It just depends on how fast you can shift to keep your momentum going.. But the shorter gear increases the chance for driver error (ie: shift time and the possibility of missing gears)..

Excuse my ignorance.. There are so many variables that this debate involves.. And I wasn't looking at all of them.. Thanks for the lesson.. I get the whole picture now..

If you see any grammar errors.. Sorry for them I'm on my iPhone..

 

As you shift up through the gears, you lose the mechanical advantage of shorter final drive gears. You have an advantage in lower gears, but once you are in a higher gear than the other car but going the same speed, you start losing the advantage.

It's pretty straightforward math. The power at the wheels is the trans gear ratio * the final drive ratio * engine torque. So in 1st from a stop, the 4.77 car has the advantage. But at speeds where the 4.77 car is in 3rd and the 4.10 car is in 2nd, the stock-geared car has the gearing advantage.

When you race from a stop, the geared car will be far enough ahead by the time it starts losing the gearing advantage that it doesn't matter. But the higher the starting speed from a roll, the sooner the stock geared car gains the upper hand.

This link will help do the math part: http://www.f-body.org/gears/

Input the relevant stock numbers, and calculate the gear/speed chart. Then do it again for 4.77's. Basically, if you have to be in 3rd at 60 mph and the stock geared car is still in 2nd, the stock-geared car has the gearing advantage.

Powerbands come into play only a bit here. If the stock-geared car is at the torque peak in 2nd at the start of the race, the 4.77 geared car is going to lose badly because it's in 3rd and has lost any gearing advantage. If you insist on starting the race when the 4.77 car is at it's torque peak, the stock car will start at a disadvantage, but as soon as the 4.77 car shifts the stock car will gain the upper hand for the rest of the race.

IOW, if the race between AP2's starts at 50 mph, the 4.77 car might jump out at the start. But if the race starts at a higher speed, like 60 mph, it will lose from the start. However, driver error (short shifting/hitting the rev limiter) and slow shifting accounts for a lot in this kind of race.

 

Thank you for your post!! It kind of puts what I was trying to say into prospective..

But it also proves that I was wrong about what I was thinking..

So basically if the 4.77 car choses the speed then the 4.10 car should be at a disadvantage.. But from my experience I chose the speed.. And I was at am advantage.. So that's why I thought otherwise..

Thanks for clearing the confusion!!

 

One thing that throws a wrench in it is that in top gear the 4.77 car will have a slightly higher top speed because it is putting more power to the ground when both cars are in 6th. So basically once the stock car hits 6th, the 4.77 car will start pulling. But who races that high with only 240 hp?

 

4.77s lower the top speed

 

Amen^^
