1) Racing
2) Curising
3) Save Gas

Thx~

 

1. around 7500rpm or maybe even a little higher if you have a good EMS

2. around 3500 to 4500 depending on if you want to jump ahead of other traffic

3. around 3000 to 3500. That will keep your turbos from spooling too much as long as you aren't flooring the gas and shifting really early.

But then again it's really hard to keep the turbos from spooling seeing as they are extremely addictive to most of us. Hope that helps.

If you're racing, you're already ******* the **** out of your car so push it to the redline.

Cruising and saving gas are pretty much the same thing. It's not when to shift, it's how hard you're accelerating. Avoid going into boost for sure because that's when you car injects more fuel to balance out the extra air entering the motor.

Simple Logic bro!

 

ooo
yeah
so logical
thx

 

For racing, it depends on your torque curve.

You want the total combination of torque for both gears(engine speed) to be the greatest. T1 in lower gear + T2 in next gear to be the highest of any such set. If I shift at 7500 instead of 6200 , I have used 1300 rpm of greatly decreasing torgue for my engine.


Look at my old dyno curve and do some stats with how rpms changes from gear to gear change and compare 7500 shift to 6500.

 

this doesn't take into account the gearing of the car. first gear multiplies torque the most, fifth the least, obviously. so each successive gear you'll be making less torque. so you probably are making more power between 6300 and 7500 in first than you would at any rpm in second. (since your torque curve is virtually flat) so you should wait to shift (at least in first) this may not be true for every gear, you have to look at the ratio of power before and after shifting, and compare it to the ratio of the gearing. if your engine makes enough torque at lower rpm to make up for the difference in gearing, then you should shift. but i don't think you can just compare the torque curve by itself. (Did that make sense? I just woke up and i can't tell)
