dont shift at 7000 grand because by the time you do it its gonna hit 72000 which is not good for the motor, the valves and pistons haven't been made strong enough to last multiple 7 grand shifts, plus your outta the power band
Fuel cut is 7050rpm's. Redline on the stock tach is 6800. I have my shiftlight going off at 6700 and has seen 7000rpms more then a few times and it runs just fine.
I think fuel cut is 7200 or 7250rpms
This is about where my power begins to fall of on the dyno. However these cars need to stay in the higher rpm each shift to start off higher in the next gear unless you are running a 4.10+ gear. I personally shift at about 6500rpm.shift by 6300-6500 or your wasting both time and engine life. 6800 is where the actual red starts on the tach and 7200 is where it'll start to kill your fuel.
