ok ive been drivin stick for about 2 years now but i got a quick simple question about revvin the engine.
ex
i move out of first and hit second revvin around 2000, i then floor it and bring my revs to 5000 but i see a stop sign ahead and i dont feel like shifting to third so is it bad to let the car rev back down to 2000.usually i would just throw it in Neutral but is it bad for the transmission to be revved to say 5000 then just let go and rev back to 2000 without braking etc.

I dont see how it can do any damage. I do it all the time its not going to wear out the clutch and its not going to add much wear and tear to the engine and can save an insignificant amount of your brake pads.

what you described is called engine braking

it's fine, wouldn't do damage. alot of people who "powershift" will rev it that high or downshift to lower gear (increasing rpm) to engine brake when slowing down.

Might waste a little extra gas leaving it at higher RPM's, but otherwise you should be fine.

wouldn't it use the same amount of gas as if it were idleing? Since no gas is being applied and if gas was being applied by the computer the car wouldn't decelarate (SP? its too late to care about spelling)

i got a simple question, what rpm is a good to shift from 1st to 2nd and 2nd to 3rd? after the 3rd, i usually shift at 3000 rpm but just wanted to hear some opinions, is it bad to go upto 4000 rpm?
thanks.

I would think if the engine is spinning at higher speeds you'd be using more gas regardless if your foot is on the gas pedal.

Depends on the engine and transmission. Wheres the red line and where about is the power curve?

Semi's use Jacob's Brakes to decelerate going downhill.

Well it's a 1999 Audi A4 1.8T with 180 hp but i got a stage 1 upgrade to 225 hp. The redline starts at 6,000 rpm and the highest RPM level shown is 7,000 but it has the same amount of space under after 7,000 (same amount of redline between 6k rpm and 7rpm).

No problems.

You can go up to your redline (6,000) but I do not suggest it as damage can occur (if you are all out accelerating go to about 5,500 to 5,800rpm's max) and escpecialy do not go above 4000rpm's if your engine is cold you can do some serious damage to the gaskets.

Of course what rpm you shift at doesn't really matter its just depending on if you are going to accelerating or cruise in the next gear.

No need to be looking at tach when shifting while casually driving. Just listen to the engine and don't let it struggle or roar.

how hard is it to put your car in reverse when you're doing 50 mph, or even a 100? or is it like putting it into first gear when you do anything over 4 mph, next to impossible?

yeah my mom's old toyota corolla had no rpm meter so i had to do that on that car but this car is modified a little so i really cant get used to listening the engine.

for those that do not know, Jacob brakes are exaust brakes. they basicly close off the exaust so no exaust can escape (gross oversimplifacation, but relitively acurate) which increases piston pressure which improves engine braking.

um.... All manual transmissions should lock out reverse while you are moving forward at any speed. Unless you wanna fvck over your car and probaly kill yourself why would you want to?

The engine braking between cars and semi's are similar but the semi's are specialized to take better advantage over engine braking. I think but am not sure that when the jacobs braking it done the pressure actualy causes the Diesel to fire while the piston is on the bottom of the cyclinder thus causeing alot more brakeing than what a normal car can do.

yep, i normally shift about 2500, 3k if i'm needing a bit more power......my moms doesn have a tach, so i used to listen to the engine to know when to shift, now i know at about what speed i normally shift at and watch that, but my acceleration is pretty uniform for every-day driving, so it's timing :D

well i usually swith to 2nd at 20 mph and 3rd at 30 mph, 4th at 45 mph and to 5th at 60-65 mph, so it's slightly over 3,000 RPM.

No one can tell you "shift at XXXX rpms" - it depends on the car. Like was mentioned - listen to the engine, and stop staring at your bloody tach before you rear-end someone. :p
