looks like it was all in your 60' time

 

[stang72]

I know a lot of it was 60 ft.But how much does the difference in da affect the 2 runs.

How was the air quality? Tune? ect. Seems more like just track time

 

[stang72]

Well the da is what looked up.But this may are may not be fair comparsion.My car was dyno tuned before but is now running BBR stage 1 cams with your email tune.

Here is what info could get.

before cams
610 elevation
71.6 f
30.23 barometric pressure
57% humidity

After cams
610
77
29.99
57

id be happy with that. your sixty foot was .08 worse but your 1/8 time was only .02 worse and even in WORSE DA you picked up 1.5 mph. that probably would have been 2 or so mph in the 1/4. and .1 or .2 better in the 1/4 with the same sixty foot. All is well dude.

edit: i only picked up 2mph (3 on one run) and .1 to .2 in the quarter with my cams. Thats about what you got and thats all there worth. my time was 1.80 and a 12.91 and then a 1.73 and a 12.60. Mph was 107.00 and 109.5-110 after.

Also, cams can affect your power band. If you were launching at your "before cams" rpm, you might need to bump that a few hundred rpm. You might also need to shift a slightly higher RPM as well.

I say you picked up around 15whp. All things being equal to the first pass, you would have run a 8.0x.

Yeah I'm working on launch.If I launch at 4500 I bog, and if launch at 5000 I spin.As for shift points before cams 6000 got the best results now shifting at 6500.I haven't tryed to vary shift points since the cams.Just want to stay at 6500 till I got my 60ft down.I don't like to try 2 things at once.So once I get my 60's down then I'll try different shift points.

Looks like you picked up about 20-25rwhp. As somone said make sure you get your shift points dialed in right for those cams. You probably want to get the car dynoed if you havent yet, so you can see where the power drops off and know where to shift at.
