Let me ask you this. I know you like reving high and all but where does gearing fall into that formula? I would think if the gears aren't tall enough then you won't be in your power band long enough anyways right?


For example: (hypothetically speaking) you have a rev happy b16 and I have a gsr b18. Lets say in the b16 first gear = 35mph second gear=62 third gear = 91mph forth gear = 117mph and fifth gets you to 140mph or whatever they top out of.

The b18 first gear 42mph second gear 72mph third gear 105mph fourth gear 128mph and fifth gear take you to 150 or whatever.

Now lets say that both cars are turboed make the same hp and the same torque. With the same weight and similar tranny setups.

Now the b16 revs to 8k and the b18 revs to 8k. Wouldn't the b18 win because the gears are taller? Not because it revs higher?


My point is you don't you have to factor in gearing in your equation somewhere?
