Allison Transmission Horsepower Limit
I was wondering how much horsepower (and torque) the stock Allison can handle, is 150 - 200 horsepower over stock too much? A lot of guys on this site have their chips at a higher level but don't mention any tranny upgrades. What HP are some of you running at with stock tranny's?
