Just wondering if Im shifting at the best time? This is what I do
1st= 5000
2nd, 3rd,= 5400

 

Oh, god no...

6200 1-2
6000 2-3, 3-4

stock camshaft and heads.

Have you even experimented with shifting at redline? You're cheating yourself out of quite a lot. The engine needs those extra RPM to be in its most effective power band after each upshift.

The goal is to produce the highest AVERAGE HP to the wheels during the 1/4.

I imagine you'll pick up 3 or 4 mph in trap speed by shifting it where it should be shifted.

 

You're et and mph aren't too bad for shifting where you do. Try taking it up to the redline and see how that does.

When I was fairly stock, I'd shift at 6000 for every gear cept 1st, which ended up about 6200 due to tach lag.

A few things done here and there, and just moderatly mod'd, I found that holding it in 3rd for as long as possible netted me the best results. With the 4.11s installed, I would cross the traps (in 4th) then hit the limiter (sometimes) just a split second later. Before the gears I was consistant at 108 mph, haven't been back since due to other problems, but I'll get some new times soon.

 

I have my PCM set to shift the car at 6200, but that's also because a supercharger ups the power band by like 600-800 RPMs. I could have it shift at 6600 and see another 2psi, but I'd have to replace my pushrods and springs/retainers first for safety

 

Stock cam needs to be shifted at 5900-6000rpm

 

Sometimes I'll short-shift first at 5500, but my best times have come when i shift all gears at no less than 6k.

 

Like I said in your last post:

<<<Uh.........you were told wrong. I shift around 5800-6100 (stock tach is slow, so I never know exactly) and except for a lid, my car is basically stock. Also, shifting would have nothing to do with your 60' time..........that would be your launch technique, but yeah, it's pretty good. Don't change that, just hold your shifts longer.>>>

 

Well like I said in my other post, if I shift anywhere past 5000 grandin first I spin the tires like crazy. And as for the other gears, my first two times at the track I tried shifting all over the place low rpm's high rpm's and both, the best I could manage was a 13.7. My third time I did the same and the method that got me consistant 13.2's was what I said earlier. I didnt ask this question because Im stupid and dont know how to shift or drive I asked because I too agree that the shift times seem to soon. Now sometimes I shift into 4th at around 5900 but the other gears I stay the same due to tire spin. I know I need new tires right now I have pirellis on 17 inch c5 wheels.

 

I have my shift light set to come on at 6,000

 

I shift at redline but I'm hitting my rev limiter just before the end of the quarter in third gear. Completely stock I ran a 13.85 last week, 2.2 @ 60 ft.
