I have a mustang for my daily driver. But also like to have some fun at night. When I race i just leave it in drive and don't redline her. shifts at alittle over 5000rpm. Will I get much performance gain if i keep her till after 6000rpm? Main reason I don't just try is b/c I don't like to beat my car to much
Ok, I tried to read the other posts and in doing so, I was left amazed. Here I am late at night, half asleep, and yet, I see a huge problem here.
Your car is an automatic and you plan on racing it quite frequently, yet, no one has made mention of a transmission cooler ? I suggest you get one of these if you don't wish to fry your transmission.
As for shifts, your stock shift points will be fine. Higher rpms for a car like yours is pointless since you have the pre 99-04 cylinder head and cam setup. If you are looking for firmer shifts, I suggest getting a good shift kit like the well-known "Jerry mod" most of us 4r70w automatic guys use. For more information on the Jerry mod, go to
www.tccoa.com and read up on their tech articles for the 4r70w automatic transmission. I'de also recommend getting a good computer tune from some place like Superchips Tuning Inc.
The advice given above about "foot-braking" is a tricky subject. Some people benefit from holding in the brake and reving up the car for launch and others have had bad results with it. If you can afford it, just get a higher stall torque converter and be done with it.
When racing, be sure to take traction control and o/d off, especially at the track. Last thing you want to do is shift into o/d at wide-open throttle. That will blow the o/d band for certain.
