This is the logic behind it, if Im understanding correctly. My RPM's in 3rd going 70 are about 4750. If Im going 70 on the highway for example, in 5th gear, and my RPM's are at say 2500, and a car pulls alongside wanting to run. If I push in the clutch, my RPM's drop to idle. I then put it into 3rd, then when I release the clutch and hit the gas, I have to wait for my RPM's to go all the way from idle to 4750 before I will accelerate once I let out. But, if I push in the clutch, put it into 3rd, rev to about 4750 and let out on the clutch while applying sufficient pressure to the gas pedal, I wont have to wait for the RPM increase, it will just hit and take off like hell. Think Ive actually spun the tires a bit at that speed doing it like that before. So I think it kinda makes a difference.
Thats if I understand it right.

The primary reasons for rev matching when d/s a manual tranny at high speeds is to get the pressure plate spinning at approx. the same rpm as the clutch disk in order to prevent excessive wear on these 2 components when they make contact, and to reduce the shock load on all of the driveline components when the clutch pedal is released.

Yea so that works pretty well. I was trying it at a slower speed. I need to practice a lot more but a few tmes I got it just right and the car lurched forward. The tires even lost traction for a second.

Glad to hear that it worked.
FWIW, you can create a 3rd gear reference sheet that shows which rpm to rev the engine to for different speeds. For instance, with 4.10 gears and stock tires your car's engine will rev at approx. 3800 at 50, 4200 at 55, 4600 at 60, 5000 at 65, and 5400 at 70.
BTW, if you don't mind my asking, where in Pa. do you live?

I liked the G37 Coupe a lot. But not the 15,000 worth of difference in the price of my GT. I paid 21K for a new GT because of Ford cash incentives and dealer's willingness to let it go for invoice. G37s were pushing 35 - 40K. The Mustang is an american icon and is faster than the vast majority of cars on the road. But there are some faster. BTW, I bet you can take a G37 from the dig for a while. Rolling is clearly their game with their better aerodynamics and 330 HP. 410s didn't help you on the roll either. 4th was to low and 5th to high.
