Re: New at this, trying to understand horse power
Pretty decent, and twice as much as the Muslim countries of Kuwait: ($2.1m)
and UAE: ($2m) combined contributed to helping their Muslim brethren in
Indonnesia. Not that Saudi was much better at 10 million, but at least they
all contributed something unlike Iran, anything ending -istan, Turkey etc.

Yes, uses for utility vehicles like Jeeps are for offroad climbing and
such which needs a lot of low end torque and slow speeds. Also, they
don't handle well at 140mph. :) They don't need a high winding 13,000
rpm engine like your Nissan example.

Gearing in the transmission and differential do take advantage of higher
reving engines and also lower torque engines and everything in
between. You choose the gearing to best suit your needs and what your
engine provides.

It's all in what you want and what you want to spend. I prefer multiple
vehicles to satisfy these 'needs'. A Jeep and a sports car is a nice
combination. I personally don't get the meld of the two into a vehicle
like the FX or the Cayenne.

Re: New at this, trying to understand horse power
Bill R U seriously trying to say that there are no modern OHC engines that can
match the horsepower/torque of a 50's cast-iron V8? Have you ever heard of
Ferrari? What about Lambourghini? I'll bet an Acura NSX can easily match any
50's cast-iron V8 w/pushrods. Pushrods are "prehistoric" because all that mass
contributes to valve float at high RPM's. Large diameter pistons (i.e. in large
displacement engines) also contribute to inefficient combustion. F1 doesn't use
pushrods -- either in motorcycles or cars.

match the horsepower/torque of a 50's cast-iron V8? Have you ever heard of
Ferrari? What about Lambourghini? I'll bet an Acura NSX can easily match any
50's cast-iron V8 w/pushrods. Pushrods are "prehistoric" because all that mass
contributes to valve float at high RPM's. Large diameter pistons (i.e. in large
displacement engines) also contribute to inefficient combustion. F1 doesn't use
pushrods -- either in motorcycles or cars.

Re: New at this, trying to understand horse power
You got something better than this six thousand horsepower fifties
