Launch RPM for a 4 Speed?

[mfchassisworks]

What do you have for a fuel pump and fuel pressure on the top end? (not at idle)

For launch RPM , to simplify it, drive the car in 2nd or 3rd the speed isn't important, start just above an idle and accelerate hard, watch the tach, the rpm when it starts to pull hard is roughly where you combination starts to work, ( you can't go by the cam card) stick cars generally have a 1400/1800 drop in rpm from the launch rpm. For example if the rpm was 3200rpm then dump the clutch at no less than 4600 etc... Launching at 3200rpm would net a 1800 rpm conv. which is wrong. If it was an automatic you would choose a 32/3400 conv.
The bog isn't really a bog, it's the motor struggling to get in it's power band. You can tune it to make it better but it won't give you the et you are looking for.
