Shift Points

[AZ3.8Camaro]

I have a 97 3.8, no Y87 package or anything. (See Below). Does anyone have a similar car who has figured out the best shifting points? Or does everyone just about redline it in every gear?

[AZ3.8Camaro]

Oh yeah, Its an M5, in case no one could deduce it. I am taking it to the track soon, so I just wanted to know.

you make max hp at 5600 rpms, so the perfect shift would happen right then and be as fast as possible.

Even a powershift (shift w/ out taking foot off gas) would be great, but VERY dangerous for the tranny if you don't know how to do it really well.

I thought the peak was 5200...

So I take it mostly everyone just redlines it? Magnus, you are experienced at the track, what have you figured out? I know you have 3.73s, but still some advice won't hurt!

magnus has an auto. Shifting around 5500 rpms should be good for a completely stock car

[AZ3.8Camaro]

Oh yeah, guess I missed that... I completely overlooked the fact that he has an auto. so 5500 it is then. I raced my friends mustang, (before i got tires) and i spun the wheels early in the gears, but it seems that my car really whoops *** in the high rpm range because i blew by him.

Right before the redline to me. [img]graemlins/thumbsup.gif[/img]

Here is what works for me.. (Auto as you know)..

The less back pressure you have, the more HP you will make at those very HIGH rpm's.

When you have more back pressure, the engine will have to work harder at those very high RPM's to make the power it might be better to shift it a little early.

I have completely stock exhaust, except a magnaflow straight through muffler, so maybe at 5300-5400 RPMS?

Yep, My shift points are completely different with exhaust off and on. I am still practicing, use assometer to figure it out. I drive back and forth and do U-turns in the same area to practice my shift points. As soon as I get them down I do something tht throws them off.

Ok. First of all I was checking your future mods...make sure you swap out those stock Z28 gears and get some lower ones. When I had my 3.23's in my car I would shift before redline. You dont want to go too high...1)Your power will drop drastically afterwards, 2)Your rev limiter might kick in and mess up your run. Even now that I got my 3.73'2, I still shift before redline...except now it pulls alot harder. [img]graemlins/burnout.gif[/img]
