Do any of you see a point of running the Boss intake if you are not launching around 6K?
i beg to differ, you typically want to shift 200-300 past when your power starts dropping off
that is why i am trying to keep a 7700 or so shift point
plus it brings you in at a higher rpm and better power range on the shift
That graph doesn't really show the power as falling off. It looks like its carrying it to me.
Unless you have a boss manifold there is no point in revving past 7.
if that's correct and what beefcake said was incorrect (since his car has a blower) then why did my car pick up mph when i shifted over 7k?N/A motor = correct.

my car has a CAI and a Xpipe and thats it.

To many variables.
i admit i am not a very consistent driver, ET-wise. however, my mph was consistent...108-109. ~100 degree temps. i was grannyshifting.To many variables.
Could be temp, 60ft, how fast or slow the actual shift was...
Were the ET's consistant?
agreed.you have to look at your dyno graph, and see where you are making power.
4v motors liked to be revved. The other thing is if power isn't dropping off that much it can still be beneficial to bring you in closer to peak torque.
A dyno to see your power band will always help.
More than likely you are shifting in a better torque position and higher in your horsepower band.
ive got 3.73s.What gear is in your car? The RPM drop between shifts may be impacting that number.

My car pulls power all the way out to 7800. Bolt ons with Boss.When I was using the stock intake, 6,800 was a good shift point for N/A. The stock intake starts to trail off past 6,500 N/A with stock heads/cams on a bolt on car.
The Boss intake shift point for me is ~7,700. The car continues to hold that power all the way to 7,800+. JJ's results are exactly the same as mine as-well-as many other's with similar mods.

Last time at the track ran the car shifting at 7300 and also 7800. I ran about .1-.2 better when shifting at 7800. best run was a 11.80@117 w/ 1.58 60ft. DA of 2800ish abovee SL.
Are any of you guys actually datalogging these passes or just assuming you are shifting at a certain RPM?
Ya that is the point I was trying to prove. Just because you think you are shifting at a certain RPM doesn't mean its actually happening. For the average Joe at the track there is just way too much going on and adrenaline pumping to be able to stare at the factory tach.
