[QUOTE="Dirty Dog, post: 453814, member: 24042"] We used regular old playing cards. Baseball cards were way too important to damage. I think the acceptability of the power output of the 3.8 is largely dependent on three things. 1 - What are you used to? I'm used to driving a stupid fast car. So it makes anything else seem more sluggish to me than to others. 2 - How seriously do you take speed limits? I grew up largely in Europe and thanks to traveling the Autobahn, I don't take highway speed limits very seriously at all. 3 - Where are you? There's a big difference between driving a 200HP 3.8 at sea level and over a pass. A sea level, assuming a minimal 15% drivetrain loss, you're putting about 170HP to the ground. Going over Monarch pass, that engine will only be making about 130 crank HP, and with the same 15% drivetrain loss you're only putting about 110HP to the ground. In reality, it's probably even worse. Drivetrain loss is 15-25%, with automatics losing more. If we assume worst case, you're putting down 150HP at sea level, and a whopping 99HP over the pass. Add in the steep incline (on Monarch, you climb something like 2600 feet in 8 miles, and it's not the steepest highway around here) and it means the JK is going to struggle. With the Olympic Training center in the area, it's entirely possible you will be passed by a bicycle... [/QUOTE]
