Shifting At Right Time

[JoeWagon]

It's been added for a while, we just need sticky on that one.

5250. just understand that you don't shift at peak, you shift to stay near peak. If you shift at peak you will drop to like 4k which isn't much power. You will develop more power holding the gear out, than if you shift and drop it down.

Also remember, the more time you can run in a gear.. the faster you will be. Shifting takes time, so you wouldn't want a 10 speed transmission even if you could stay within ~500rpm of peak power.

It's about the same in every gear.. but remember: the wider/taller the gear, the more you will drop when you shift. If you shift at 6k in first, you will lose time because you're not near peak again (probably 4k) so going to 7 lets you drop to 4.5 or 5.

Kevin's gears are stock. The only lengthening I know is beneficial is 5th gear (to drop RPM's are cruising) which doesn't affect racing. It might help your 1/4 time if you got gears for your setup, but they aren't available.

I still run stock gear ratios. Torque and HP always cross at 5252 rpm. But just because torque is dropping off somewhere above that, doesnt mean that you should shift. Dont forget that the next higher gear will have LESS torque multiplication than the current gear. My whole point above is that this is about wheel torque, not engine torque. Which is why you need the gear ratios to figure out when you should be shifting. When you would have more wheel torque in the next gear than you have in the current gear, you should be shifting. Shift point from gear to gear will change because wheel torque will vary between gears.

I sift at 6k every gear should i change, I have a UICP,1g bov,airfilter and mas air flow adapter. I shift with my foot staying on the gas to the floor and push the clutch in hit the next gear and let the clutch go( very fast movment)

Do 7k in first (this may be different for FWD, but it should be ok) and 6k in subsequent gears. Speed shifting is fine if you have the traction to make use of it.

if somone applied this to their car, why wouldnt they want to swap to an automatic and set these perfect shift points for perfect track times

[JoeWagon]

Although an TYPICAL auto may shift faster, they seem not to be faster in the 1/4. No doubt part of that is weight, and there's a lot of inefficiency about an automatic transmission. You lose power through all the friction, etc...

Now if we are talking about an F1 style gearbox... then I would have to agree it has the possibility of being much much faster.

Thats right. Auto trannys suck up a ton of power, especially in the torque converter. And they are a lot heavier as mentioned.
