RE: Overdrive off

Why would you even turn it off for a race??? It does nothing to have it turned off except it will never shift into O/D. It doesn't make it any faster or anything. That makes no sense to me to want to drive at 4k rpms. H pipes sound better at lower rpms. If you like high rpms get an x pipe, they sound better at higher rpms than h's. Or better yet I'd say get a civic or something if you like to keep the engine wound up like that.

RE: Overdrive off
I have an 02 Auto 4.6 running 373 RWHP and I leave the overdrive on except when I nail it. Since I am running 3:73 gears, I tach out at about 118mph and I can feel the rev limiter hinting back and forth. When I activate the overdrive at that time, I can go till 138mph. Yes, it does rev higher with the overdrive off and it will not hurt the engine in it's self, but as a rule of thumb, higher revs will wear out an engine faster, that is obvious. If you want to drive with overdrive off all the time, you will lose about 1 to 1 1/2 miles per gallon and the action will cause your computer to relearn your driving style. You can expect a loss of passing gear for a few days untill your computer gets reacculamated with the higher rpm settings.
Out of curiosity, do you get passing gear every time you hit on it? I ask because I don't and it annoys me big time. I would say I get a drop 50 percent of the time with a really strong kick down 1 in 10 times. Any imput would be appreciated.

RE: Overdrive off
Wow man no need to get all defensive about it. I'm just wondering why you would want to run your car at 4k all the time. I mean you have a muscle car that's pretty loud even at low rpms since you have exhaust, and its gonna stand out no matter what without riding around at 4k. I'm not gonna tell you what you're doing is wrong just trying to understand.

Turning the OD off does change the shift pattern for all gears. Cruise at 30 and turn it off, jumps 500 RPM's. Take it to the floor and it olds each gear longer. I'm sure its just a computer change.

RE: Overdrive off
If you are WOT the car is gonna shift the same with the O/D off or on. It will shift at the redline. Now if you're not at WOT then it probably does shift differently. But I doubt that it makes your car any faster to run it with the O/D off. No matter what at WOT its gonna shift at the redline.
