"Improving breathing is one of the keys for power enhancement. Unquestionably, in the 2-valve era valves used to be the bottleneck, hence the need for more valves...A typical 2-valve engine has just 1/3 combustion chamber head area covered by the valves, but a 4-valve head increases that to more than 50%, hence smoother and quicker breathing. 4-valve design also benefit a clean and effective combustion, because the spark plug can be placed in the middle...Formula One cars and even the Ferrari F1 cars which was once famous for 5V engine has switched back to 4-valve design a few years ago...In the mid-80s, both Honda and Toyota made 4-valve engines standard in virtually all mainstream models. The Western car makers did that some 10 years later!"
Also consider this:
Your extra .3 liters in your Jeep SOHC is only giving you 20 more horses and 15 lb/ft torque (at 800 RPMs higher) more than the Toyota's 8 year old 3.4.
By comparison, the Toyota's new DOHC 4.0's extra .3 liters is making 35 more horses and 48 lb/ft torque (at only 3400 RPMs) than your SOHC 3.7.
Why is the extra .3 liters in the Toyota DOHC making so much more power than your extra .3 liters?
You stated "if the shootout between tacoma, wranger, and hummer was just a year ago, can you direct me to it? just fyi, it was a 1998 four-wheeler article i believe. you know, the first year for the TRD pkg., and you know what scorpio says, whatever is new and hot in it's first year usually wins the awards"
Nope, the Tacoma has been winning awards since its first year and continually thereafter. Sorry.
You stated "either way, your tacoma is still down on power and torque to the liberty, not to mention the all important mileage thing. and that's hilarious."
Nope, we've already been down this road. The Tacoma has the better power to weight ratio. Your extra 600lbs more than cancels out your miniscule torque advantage you keep bragging about.
Better mileage? Nope, in V6, 4x4 trim and auto tranny, the Liberty gets 16/20, the Tacoma 17/19 (manual Tacoma probably even better). Please explain to us all how the Liberty gets better mileage. I'm dying to hear this one!
"Can I come and visit you in that world you live in..? I am tired of reality."
I couldn't agree more!
