4.6L 3v engine.
I plan to get some dyno runs in soon so I can calculate the optimal shift points for each gear, but I'm wondering how far you can go and still be safe.
It's seeing where the max torque/HP is and shifting within that range.
You actually want to shift before it goes beyond those ranges.
Autocross? Who needs valve springs anyway?
Why would you ever want to shift before max HP?? You want to maximize the average power to the wheels in each gear. That will always be after the peak in the curve. Unless the HP drop off a cliff right after peak, but I have never seen an engine drop THAT fast.
you guys on stock engines with minor changes (Intake, catback, tune) were do you find the optimal shift point? for the 2005-2009 4.6L motor.
I don't have a stock engine right now but I can recall what I was told when I did have the stock engine.you guys on stock engines with minor changes (Intake, catback, tune) were do you find the optimal shift point? for the 2005-2009 4.6L motor.
