Choose a gear so that car is between 65 and 70 mph at 4000 RPM.
Cruise at just above 4000 RPM, coast down to 4000, then floor it.
The data should look like this:
Setting 0 time to be whatever time it hits 100 kPa, here is sample data format (not actual)
5 psi - 0.2 sec
10 psi - 0.5 sec
12 psi - 0.6 sec
15 psi - 0.8 sec

Wow, that would really throw this thread for a loop. I was thinking displacement ranging from 1.6-2.1L not 1.6-7.0......and just to make sure this thread is basically a dick measuring contest, correct? lol Not really relevant except for initial spool for highway racing?
To a noob like you, yes.
To others, like Jason, no.
If you read through our previous spool thread and glance over the plotted charts with everyones contributed info, you'll find it very helpful since you will see what combo's produce what curves.
Post less.
Read more.
