What ideal RPM should I shift?

As far as rpm to shift to match a V6....it depends on the powerband of the two engines. If you have a low RPM torque-y 4-cyl, you'd need to shift SOONER than the V6. Or if it's a turbo car, with a high rpm band....you'd need to shift later.

Just depends on the exact engine, specs, etc and so forth.

And yes, reving higher will add wear and tear and affect gas mileage.3. Old Man Dirt Says: How fast a car accelerates is dependent on the HP to weight ratio and the gear ratio of the differential - not the number of cylinders.
The ideal shift point is determined by what end result the driver wants.
I don't know if I could handle a car with a shift point as low as you are talking about. My Miata's like a shift point of about 7500 for acceleration and 4500 for fuel economy. I don't consider this a high RPM engine by the way. A high RPM engine (IMHO) can handle 10000 + RPMS Tag: What ideal RPM should I shift?
